Article
Full-text available
This paper includes weight optimization method of rotor and analysis of total power loss in radial magnetic bearing consisting of four, eight and twelve poles. Weight optimization reduces copper loss in bearing since the electromagnetic force is reduced due to optimized rotor. Further numbers of poles in magnetic bearing are varied for same electro...

Full-text available
The magnetic bearing works on the principle of magnetic levitation. Integration of the geometric and control designs is the current trend in mechatronic products. Conventionally, in control of rotors in the vertical direction, it must be supported at two places by radial magnetic bearings. A thrust magnetic bearing is also provided to prevent axial...
Article
Full-text available
A typical problem of radial magnetic bearing is chosen and bearing involving n-pole pairs, where n = 2,3,4,6,8, are designed. Various losses occurring in magnetic bearings such as copper loss, eddy current loss, hysteresis loss, windage loss are summarized as total loss and the methods of evaluating are discussed. Each individual loss and total los...
Article
Full-text available
Weight optimization of coil in eight pole radial magnetic bearings (RMB) has been carried out using multi-objective genetic algorithms (MOGAs). The coil weight of RMB and copper loss has been selected as the minimization type objective function. The maximum space available, saturation flux density, the maximum current densities that can be supplied...
Research
Standard fibers have attracted the attentiveness of technocrats, specialists, experts, and researchers throughout the globe as elective support for fiber built up polymer composites, due to their predominant properties like high explicit strength, low weight, minimal expense, truly incredible mechanical properties, non-grating, eco-accommodating, a...
Article
Radial magnetic bearing (RMB) works on magnetic levitation principle. Use of magnetic forces for supporting a shaft has been topic of interest of researchers. Shaft supported using magnetic force eliminates the use of lubricant and these bearing are free from rubbing action between the surfaces. Application of turbine rotor 60 mm diameter is taken...
Article
Technocrats and researchers are attracted to the Polymer Matrix Composite (PMC) material due to its predominant mechanical properties. It has been observed from the literature survey that, use of any of the natural fibers alone from the available category like, Bast fibers e.g. jute, kenaf etc., Leaf fibers e.g. Sisal, Banana etc, Grass fibers e.g....
Article
The sheet-metal parts have already replaced many expensive cast, forged, and machined products in today’s practical and cost-conscious world. The factor is obviously the relative cheapness of these methods, or otherwise mass-produced parts, as well as greater control of their technical and aesthetic parameters. Press working is generally defined as...
Article
The rapid developments of vehicle technology over the last few decades, flywheels have been used to achieve smooth operation of machines. The early models where purely mechanical consisting of only a stone wheel attached to an axle. Nowadays, flywheels are complex constructions where energy is stored mechanically and transferred to an integrated mo...

The friction brake pads are an important component in the braking system of an automotive. As there is conversion of kinetic energy to heat energy, temperature of friction pair increases which causes coefficient of friction to decrease. This paper gives information about the work done by many researchers to stabilize the coefficient of friction and...
Article

Knowledge of End mill tool performance during milling machining of work material is much required in order to improve the effectiveness of the machining process. The tool-workpiece impact and correlated effects of tool wear and surface roughness are regularly the subjects of importance, although, more work has been done to set up the connection bet...

Finite Element Analysis (FEA) is a numerical technique (Numerical analysis, means the study of algorithms that use numerical approximation, for the problems of mathematical analysis, as distinguished from discrete mathematics) for finding approximate solutions to boundary value problems. It uses methods of variations (the calculus of variations, me...

Pelton wheel turbine is generally used for mechanical power generation in hydroelectric power plant. Vibration produced in the system is forced vibration. The dynamic characteristics of a hydro turbine power depend heavily on changes in load disturbances. Thus the hydro turbine exhibits highly nonlinear, non-stationary system whose characteristics...

Smooth-running of internal combustion engine is possible because of exhaust valve. Role of the exhaust valve is to pass on the exhaust gases to the exhaust manifold from the combustion chamber. During the operation of internal combustion engine, exhaust valves are subjected to the axial stresses due to exhaust gas pressure, cyclic stresses due to r...

The presence of a crack is hazardous problem in the performance of many structures and it affects many of the vibration parameters like Natural frequency and mode shapes. Crack in a structure changes the dynamic behaviour of the structure and by examining this change, crack size and location can be identified. Current research has focused on using...
