Conference Paper
Full-text available
In this paper, sea wave power plant was designed to be applied in southern coast of Yogyakarta, Indonesia. The plant was expected to generate 700 Wp output. It had two components: tubular linear permanent magnet generator (TLPMG) and floater buoy. The buoy and the ocean wave were assumed moving continuously. By this condition, the generator was the...
Conference Paper

This paper aimed to find out a model of 1 kWp flat-quasi linear permanent magnet generator (LPMG) for ocean wave power plant in South Java Ocean. First, a flat-quasi LPMG is modeled based on the wave characteristic at the placement site. The model was then simulated using finite element software of FEMM 4.2. Next, the model was optimized to find ou...
Article
Full-text available
Flat-quasi type of linear permanent magnet generators (LPMGs) have been considered to be applied for several applications, such for wave energy conversion and free piston combustion engine. One of the important issues concerning LPMG is the permanent magnets configuration, due to its effects to the generator’s excitation performance. In this paper,...

Indonesia has several potential ocean energies to utilize. One of them is tidal wave energy, which the potential is about 6 GW. To convert the tidal wave energy to electricity, linear permanent magnet generator (LPMG) is considered as the best appliance. In this paper, a pico-scale tidal wave power converter was designed using quasi-flat LPMG. The...
Conference Paper
Full-text available
Burning process of fossil fuels in electrical power plants has been known to release carbon emission, which lead to global climate change. In Indonesia, the fossil fuels cover about 85% of fuel usage for electrical power plants. This amount should be reduced by increasing the utilization of renewable energy for the plants. However, several barriers...

span lang="EN-US">This paper proposes a design of a 5 kW, 100 volts brushless direct current (DC) (BLDC) motor using an existing stator connected to an inverter and equipped with Hall sensors. The stator is a radial flux motor-type with 54 slots positioned at the outer side of the machine. In this case, the design is focused on the rotor components...

For generating electricity, direct-drive wave energy converters (WECs) with linear permanent magnet generators (LPMGs) have advantages in terms of efficiency, simplicity, and force-to-weight ratio over WEC with rotary generators. However, the converter’s work under approaching-real wave conditions should be investigated. This paper studies the perf...
Conference Paper
This paper analyzes the performance of point absorber wave energy converter (WEC) system using linear permanent magnet generator (LPMG) under regular wave condition. First, a WEC design was modeled. It consists of a floater as wave's mechanical energy capturer, coupled to an LPMG as power take-off system. Then, operation of the WEC system was simul...
Article
Linear permanent magnet generator (LPMG) is an essential component in recent wave energy converter (WEC) which exploits wave's heave motion. It could be classified into tubular-type, flat-tricore type, and quasi-flat type. In previous researches, these three models have been studied and designed for pico-scale WEC. Design optimization has further b...
Conference Paper
Electricity is one of the most important sources of energy in the world. Its use is increasing rapidly for home appliances and industrial apparatus to support every activity in both developed and developing countries. Small-scale, distributed and autonomous power system are all developed in concern about the energy conservation as well as environme...
Conference Paper
Full-text available
South coast of Java has been highly preferred as the placement location of wave energy converter, due to its relatively huge energy potential. Furthermore, linear permanent magnet generator (LPMG) has became one of the popular methods to convert wave energy to electrical energy. Based on the shape of stator core, there are several models of LPMG. Q...
Conference Paper
Full-text available
Conventional tubular linear permanent magnet generator (LPMG) is composed of permanent magnets which are placed in translator, and stator which is made of iron. However, this topology suffers from relatively huge cogging force due to interaction between the magnet and the iron, also large core losses from hysteresis and eddy current. To reduce the...
Conference Paper
According to statistical data, human population in Indonesia is increasing rapidly with population growth rate 1.49 % per year. The effect from high population growth in Indonesia causes several problems. One of the problems is that lot of productive agricultural land has been converted into residential land. On the other hand, the need of foods an...
