Motor - Science topic

first i saw this video then i do some searching in theory i found it possible but in real world i dont see clearly application just this video down.

so what you thing ?

I am using a polygon mirror scanner that have 6 facets and the dc brushless motor speed was given 10,000 RPM. Now I want to know how to calculate the polygon speed if I change the power supply voltage.

Hello everyone,

I'm administering subanesthetic doses of ketamine to mice (10 mg/kg; i.p.), and I noticed that their motor coordination becomes compromised for up to an hour following injection. Has anyone experienced this with their mice or do I have to reconsider?

Despite the available evidence (in other words bad reputation) on the use of cortidoids in patients with acute spinal cord injury and the correlation with some complications such as gastrointestinal bleeding among others, and not finding significant changes with respect to control groups studies. Such as the 2020 meta-analysis of the Journal club entitled High dose methilprednisolone for acute spinal cord injury.

In your own daily practice, how do you manage this type of ASCI patients in your health centers?

Do you considerer use any corticosteroid?, either methylprednisolone or dexamethasone or some other in an empirical or modified form and not necessarily as indicated by the traditional NACSIS studies?

I am referring specifically to the personal decision between using it and not using it, personally I have seen good results not necessarily with such high doses and not with methylprednisolone. but I have indeed seen improvement in a few hours on the motor test compared to the first motor test. Regardless of whether it is a surgical candidate or not.

I appreciate your opinion,

Best regards,

How to solve the interference of magnetic field from the energized phase on the non energized phase of a two-phase stepper motor under full step drive

I would like to enhance the torque out of motor by enhancing the dimensions as i have the flexibility to increase the dimensions....In this context I am not changing voltage and current....by doing so, i observe the back emf is increasing and it is beyond the voltage limit which is against the principles....How to overcome this issue...

Can I change the input parameters to the motor to enhance the torque??? May i know what is the principle to enhance the torque density of motor?

I am trying to move aircravt propeller from horizontal to vertical position in 10 seconds. What will be forces acting on the propeller and how will they affect the toque required from motor

Hello dear colleagues,

I am looking for a elastic actuator for a robotic arm. It should be able to contribute 1/3rd in lifting the arm with the motor as the motor contributes 2/3rd. It should also ensure safe landing of the arm instead of free fall and also during emergency situations like, if the motor's program is bugged and it actuates in the wrong direction then also the actuator should ensure safe landing. My intial ideas were a spring and damper syste, torsional spring alone but there are some restrictions with them so, please suggest something.

Hello

Thank you

In recent years, in connection with the inclusion of the agricultural sector in the process of green transformation of the economy as well, new solutions are being sought, created and implemented to enable the transformation of productive farms into sustainable, pro-environmental, pro-climate, organic farms growing crops and other aspects of agricultural activity in accordance with the principles of organic farming and with the simultaneous implementation of sustainable development goals. Accordingly, on a farm operated in accordance with the formula of sustainable organic agriculture, pesticides and other chemical pesticides and chemically produced fertilizers are not used in agricultural crops, energy is obtained from renewable and emission-free energy sources, water is obtained mainly from rainwater catchment facilities, organic manure and processed organic waste from composters are used to fertilize farm fields, crop rotations are used within the framework of multi-year cycles to restore high soil quality and prevent soil aridity, individual farm fields are separated by green belts and flower meadows to provide foraging areas for pollinating insects, on-farm mini-treatment plants are built to treat wastewater generated on the farm and not used in a specific way for farm purposes, etc. Besides, on a farm run according to the formula of sustainable organic farming, available technologies for the production of biofuels based on organic compost, from organic waste from agricultural crops, through which motor fuel is produced to power tractors and other agricultural machinery, should be used. These may include the construction of biogas plants, where biogas can be produced, which can then be used to power agricultural machinery. Besides, in a sustainable, ecological, pro-environmental, pro-climate farm, agro-tourism activities may also be developed, and certain preserves, food products, such as jams, juices, cheeses, etc., may be produced within the framework of a micro-production activity or manufactory, within the framework of local brands on the basis of organically produced, cultivated crops. In addition, such sustainable, organic agritourism farms may be associated within a local producers' cooperative with silos, warehouses, etc. in which crops from the cultivation of several or more locally operating farms and/or agritourism farms are stored, including or mainly, only those operating under the formula of sustainable organic farming.

In view of the above, I address the following question to the esteemed community of scientists and researchers:

And what is your opinion on this topic?

Dear ResearchGaters

For some time now I have been hopelessly searching for a new internal permanent magnet synchronous machine (IPMSM). In our lab we only have SPMSM (surface-PMSM) types, so I would like to purchase an IPMSM to expand our research topics and teaching capabilities.

However, it is almost impossible to find them in datasheets and on European manufacturers' websites (well, not without writing directly to sales support) because the Ld/Lq ratios are usually missing in the motor type specifications. Nor are their specific names given in publications.

Therefore, I would like to kindly ask you if you have any IPMSMs at your workplace and if you can provide me with their nameplate (motor name) and manufacturer information so that I can try to order one. Alternatively, if you can provide me with a tip on an IPMSM from a specific manufacturer, I would be very grateful.

I am particularly interested in motors with the following ratings - rated power < 3 kW, rated frequency > 50 Hz. Encoder included. The other nominal values are not that important (except of course Ld<Lq). My budget is around 1000 EUR, so motors with lower power ratings would probably be more suitable.

I would prefer to choose motors available on the European market, as the invoice will have to be paid by the university, which has very conservative payment practices. So stores like ebay, alibaba, etc. are out of the question unfortunately (even if it would be cheaper).

Should I compare the natural frequency to RPM of motor? or is it related to cogging torque? How do I know if my motor remains stable & won't vibrate at natural frequencies?

When considering dynamic loads (induction motor loads) in an isolated microgrid, should the induction motors be directly connected to the grid, or should they be connected to the grid through an AC-AC converter?

What are the methods of gluing the internal insulators to the case of a composite solid-propellant rocket motors?

I want to use an ac motor in proteus but I couldn't find. So how can I get that motor ?

I want to do Open loop analysis of BLDC motor. While doing so, when I want to connect BLDC motor block with 3-phase inverter in Simulink, it don't let me to connect it. This is the desired circuit which I want to connect it with.

In robotics, we use DC motors in joints. Sometimes, we see overshoots in the output torque from these DC motors. Can someone please explain why these overshoots occur and what are the possible ways to reduce these overshoots?

i am searching for new sensors that is used in cars for effective performance of motor.

can you give me a book or paper or introduce me a site?

I would like to ask a question about using of linear motor E1100.

I downloaded linear motor software to computer. It is working. I can work command table mode, triggered command table and triggered time curve, continuous curve at run mode selection. But i can not adjust force control. I watched linmot tutorials in youtube.  But still I can not do this.

i used command table with the following commands

id1:vai go to pos with force ctrl limit and target force(target position:70, maximal velocity:0.01, acceleration 1 m/s2, force limit:14N, target force: 15N)(383xh)

id2:vai go to pos from act pos and reset force control (381xh)

these commands give error:pos lag always too big

description: the motor was not able to follow the demand position. the maximal allowed position difference is definwd through parameter. 1473h(error limit)

recommend actions: check the motor load, check the motor stroke range for possible collisions, check the position controller setup, check the setpoint generation (unreachable speed/acceleration values?), check the motor sizing.

I want to apply 15 N force to my textile pressure sensors by continuous cycles. Could ypu suggest something? Should I change the homing position and how?

thank you so much

I am happy to share my new paper related to EV applications, which is currently an emerging area of research. I request everyone to please share my paper with your knows or groups.

A PIC microcontroller-based Robotic Arm is a project that involves the design and construction of a robotic arm that is controlled using a PIC microcontroller. The goal of the project is to create a robotic arm that can perform a range of tasks, such as picking and placing objects, manipulating tools, and executing pre-programmed sequences. The robotic arm is typically made up of several servo motors, which are used to control the movement of the arm's joints. The PIC microcontroller is responsible for receiving commands from the user, processing these commands, and sending the appropriate signals to the servo motors to control the movement of the arm. The primary aim is to manually control the servo motors and in later stages include the use of control algorithms, such as inverse kinematics, to determine the optimal path of the arm for a given task.

I had a plan to run the GDI injector for a single pulse injection. This injector draws high current and voltage for its operation. For that I used a GDI injector, Arduino Atmega 2560, Motor Shield, and 12V Battery source. The motor shield was fixed with Arduino pin-wise for easy operation and control. The jumper wire was kept on during this process as the power supply is only by battery for both Arduino and motor shield. The connections are follows (can be seen from figure):

The code was processed to run the injector for 20 ms of operation as follows:

#include <AFMotor.h>

AF_DCMotor motor1 (1);

void setup() { // put your setup code here, to run once:

}

void loop() { // put your main code here, to run repeatedly: motor1.setSpeed(500); motor1.run(FORWARD); delay(20); motor1.run(RELEASE); delay(10000);

}

The injector was actuating with very low power and seems will not be able to actuate for sufficient flow rate. However, when the injector was connected in direct contact with battery previously, it was grabbing more current and a large tick sound was observed assuming good operation.

Hi everyone. I have three questions about stranded windings in Ansys Maxwell and how to calculate their losses. Also, I want to know how to calculate friction losses in a motor, so I define it in RMxprt. I want to simulate a synchronous motor. It has 12 stranded windings. Each winding has 24 thin wires that act as one wire, with 5 turns. I want to know how I should tell the software that my windings are like this. And how should I define friction and winding losses in it? Thanks for your responses

comparisons for speed control of BLDC motor

I am looking for information about the generation of CO2 emitted by small fishing boats. The information can be of any type of small-scale boats, or of the types of engines that are used in this type of boats (outboard motors), mainly gasoline, and even diesel engines. I appreciate your feedback.

connecting rod of 250 cm long and 5 cm diameter is connected with motor and 3 blade at other end. 3 phase electric motor gives 5 hp and 1500 rpm to the given object. Rotating object rotates at 1500 rpm then switched off the motor. after doing so how much time it takes to completely stops and how much revolution. linear velocity is 7.85 m/s and acceleration is 7.85 m/s^2. 3 blade radius is 63.5 cm. used material is Al6061. Take total mass of rotating object is 15.4 kg. 3 blade and rod are hollow type object that's why photo and given 15.4 kg may vary. But take total mass 15.4 kg. 3 blade mass is 8.4 kg and rod mass is 7 kg.

I would like indications of works and articles about the project I am developing. A gearbox with multiple motors and only output shaft that will work like the engine in a longtail boat.

Guten Tag allerseits, hello everyone,

in search of an answer I decided to post my question in this forum and hope to gather lots of different thoughts:

I've been wondering about the origin of the cognitive vs. motor tasks distinction - historically, what are the roots of separating so-called 'cognitive' from 'motor' tasks? Who was the first to talk about it? Which disciplines used this separation for their research?

(I have some answers in my mind, that I will add later in the discussion; don't want to direct readers' thoughts already.)

Looking forward to reading your ideas - and: warm thanks for contributing to this question

Hi all,

I have a longitudinal study design of Parkinson's patients (about 8 years follow-up data) and I want to run a model that will examine how clinical variables (ex. motor function) influence functional ability. For this I wanted to run a generalized linear mixed model (GENLINMIXED) in SPSS and I am having some trouble setting it up.

My dependent (outcome) variable is the Schwab and england score, which has a skewed distribution therefore the need for a generalized model. As fixed effects I have months of follow-up, age, education, motor severity (etc. etc.). Random effects are the intercept.

Now my main problem is that in SPSS I can include a repeated measure - however it is difficult to find information on 1) whether I should include one and 2) what to put in. For example, I have seen a study including time as the repeated measure, and another which used age because age was repeated each visit?

Could anyone guide me on the use of the repeated measures in GLMM? Running the models with and without the 'repeated_measures' part gives very different results unfortunately.

I have pasted my syntax below, the bolded part is what I am confused about. EVENT_months is the visit date (0, 12 months, 24 months, etc) and FU_months is the actual months elapsed (which will be different for each participant).

What should be my specific objectives

BLDC controller have 3 speeds provided, by default 2 speed is selected, when i select the 1 speed, 2 speed or 3 speed there will be no kind of change is made by the controller on BLDC motor, i am not getting which type of problem is it. can you guys help me to sort out this problem.

Dear folks,

I'm working on a design for a solar panel fixture for a capstone project. I have a panel weighing 20 lbs and with the frame, it's overall 35 lbs. The panel assembly will be mounted on a rod (48in long) using 6 routing clamps, and the rod has 2 bearings attached to the ends. I want to determine how much torque will I need to rotate this solar panel assembly, therefore using that to determine the size of the motor. And, to determine the radial and axial load to choose the right bearings. The speed will be 5rpm. Would be much appreciated if someone can provide support.

I need to know the motor torque that can provide me a clamp force of 98N using a cable pulley mechanism as shown below in the figure. Any suggestion on how should I should approach to tackle this problem?

Regards,

Sameed.

Hello, I'm a beginner at matlab/simulink and EV.

Recently, I studied EV fuel efficiency simulation using matlab and simulink, but there is something I don't understand. The MCT method (measured by dividing into UDDS, HWFET, and constant-speed sections) was used to measure fuel efficiency, and simulation output data (Time, Distance, Battery SOC, motor RPM, motor Torque, SOC voltage, Electric consumption current, Electric power) were obtained.

Based on these data, I would like to calculate the total amount of battery discharge energy and charge energy for this vehicle. When measured using an actual car rather than a simulation, the discharge energy amount was 37kWh and the charge amount was 42kWh. The actual battery specifications were 120Ah, 319.4V. I used a machine for actual measurement, but I wonder which data I should use to calculate the simulation using the output data above. And I also want to know how to calculate it.

I've actually tried it

1. integrate Electric power

2. To multiply the motor current and SOC voltage and integrate the results

But I can't judge whether these two methods are correct or not. I need your help. Thank you.

How to drive a 36v motor within Arduino hardware?

I am attempting to perform electrophysiology recordings from electrodes implanted in the brain of a rat while he is walking on a treadmill. Currently the noise level is extremely high (Strongest at 60Hz and 120Hz, but enough across the spectrum to be unfilterable) when the motor on the treadmill is in operation, even when the rat is ~5m away. I have tried grounding the metal body of the treadmill, but without much benefit. The recording system is a Plexon Omniplex system. Is this typical for treadmill recordings, and what is the typical approach at reducing this noise?

about drone but motors downwards

I want to focus on electric vehicle motor design in my thesis. There are many types of motors made in this field in the sector. My aim is to address a less studied type of motor. My studies will not only be theoretical, but I am aiming for a research that can be done in practice.Is there a motor type that you would recommend to me in this field in terms of the capabilities of the Ansys program?

Thank you in advance for your answers.

Best regards

I am in the preliminary design phase of a heavy-lift octocopter. Is there a systematic approach to selecting the proper propeller, motor, and battery for the given configuration provided that the frame size is still variable, the required payload weight is W and the endurance is T minutes?

All of the above parameters are coupled so I am guessing this will be an interactive solution. Any suggestions?

Thank you in advance for your advice and guidance,

Hello,

I am working on an inductive resonant wireless power transfer technology and using NFC for communication between the transmitter and receiver sides. My aim is to transfer the power of 1.5kW from the transmitter side to the receiver side with resistive and motor load. I achieved it with the bulb load (resistive load) but with DC motor load the NFC communication is interrupting as soon as the motor turns ON, I tried to run the motor at a very low voltage to reduce the noise generated by the motor but that too is not helping. I need your expert opinion on this to resolve the issue.

System detail:

Input voltage 230V ac, output voltage:230V Dc, 6.5Amp.

Transmitter side details: Rectifier stage, H-bridge, series resonance

Receiver side details: Series resonance, Uncontrolled HF full bridge rectifier, DC bulk cap, DC motor (as a load)

NFC details: protocol- NFC-A/ISO14443A.

Anyone please tell me how to interface L298N stepper motor module to PLC S7-1200.

I have seen that almost all four-wheeler commercial vehicles or power requirements over 10 kW, PMSM or Induction motors are used. Is the reason behind this is more torque ripple and lower speed range of BLDC motors? What are the other reasons?

But if I want to use a BLDC motor for a power requirement of around 40 kW in an EV, considering better power density, what are the disadvantages that can be faced. What are the other advantages of BLDC that can support its application in this case?

Is there any commercial EV that is using a BLDC motor for the power requirement range of 30-50 kW?

I am using stepper motors to transport nanofibers in an electrospinnig setup. Howaver with the electric field (46 kV) I applied, the stepper motor drivers give an error and the motors do not work. I grounded the motor and drivers. I used UPS (Uninterruptible Power Supply). But the same problem persists. Why does a stepper motor exposed to an electric field put itself in protection mode? What can be done so that the driver does not give an error?

Hello everyone,

i have a question regarding event/task-related EEG data. Are there any indications that baseline power increases from trial to trial? For example, in the case of a fine motor task (e.g. finger movement), that baseline power slowly accumulates from trial to trial through the task (baseline power trial 1 < trial 100)?

I am aware that the time between trials should be such that there is a return to baseline. However, if the power increases slowly, could it be that an effect is only seen after 70-80 trials?

Does anyone have experience or know of studies that can provide guidance on this issue?

Regards

Niko

Hi, All,

We have an Agilent 1100 HPLC with an attached evaporative light-scattering detector (ELSD). The analog-to-digital conversion was done by a 35900E A/D converter. Alas, the 35900E has died (fan motor bearing seized during unattended operation), and we discovered that Agilent no longer sells or supports the 35900E. Instead, they have something called a universal interface box 2 (UIB2).

Can anyone tell me if the UIB2 is a drop-in replacement for the 35900E? Will it work with ChemStation version B.04.03-SP1 [87]?

Thanks for your time and attention!

I am working on a paper that focuses on GTO to GEO satellite transfer maneuver. In most of scientific papers, constant thrust magnitude model has been considered for AKM or low thrust engines. Is there any liquid continuous or electric low thrust engine with controllable thrust magnitude? Or we should always consider constant thrust magnitude.

I would be grateful if you could mention some references.

I have read papers on multilevel inverter feeding BLDC motor drives. My question is BLDC motor having trapezoidal back-emf, is it possible to drive the BLDC motor using an l inverter that gives a perfectly sinusoidal voltage output? Also, I would like to get clarified about the stability of such a drive and torque ripple. I will be grateful to you if you could kindly let me know the significance of such an inverter application to BLDC motor drives.

I have designed an SRM for fan application that has a rated speed of 1400 rpm but the controllability for the torque ripple minimization is not achieved with the design. for example, I want a rated current of 4A at the rated condition and the hysteresis controller is used to minimize the torque ripple but at a rated speed of 1400 rpm, the motor is not permitting the rated current because of large dL/dtheta(large back emf in the rising inductance zone). Due to this, the current can't reach near the rated current(4A) and hysteresis control is not working. The number of turns can't decrease because of the MMF requirement in the pole as per the rated torque. The volume of the motor has certain limitations so I can't increase the length or diameter. So, please help me out on this issue. I will be highly obliged for your time and support. Thanks & Regards
