Design and Modified Radial Flux Synchronous Generator Using V-Shaped Permanent Magnet Method

Abstract

Indonesia has the potential for low speed wind energy which can be used as an energy source for electricity generation. Permanent Magnet Synchronous Generator (PMSG) is a technology used for applications in wind turbines. Permanent Magnet Generators based on the direction of the flux are categorized into two groups, namely radial flux and axial flux. PMSG technology with radial flux direction has been developed with various geometric variations used to overcome common problems in generator performance, one of which is by modifying the modeling of the stator iron core and rotor. Therefore, it is necessary to develop low speed PMSG with radial flux direction. In this paper, a design and simulation will be carried out using the umbrella field method on the stator design and the V-Shaped Magnet Neodymium (NdFeB) model in the rotor design based on specifications to obtain performance values when the engine is operating. The generator is designed to get a voltage of 140 volts and 200 watts of power at a speed of 750 RPM. The design and simulation process was carried out using Finite Element Method (FEM) based software.
