Abstract
Low-speed permanent magnet synchronous generator (PMSG) has the characteristics of high torque and low voltage. This study presents an optimized design about an outside rotor 10 kW low speed PMSG which is in the vertical vane wheel hydro-generator unit. Maxwell software is used to establish the finite element model of the low-speed PMSG, and the simulation analysis including three-phase flux waveforms, induced voltage waveforms, voltage waveforms, current waveforms, flux density distribution and torque characteristic curve is carried out under the no-load and rated load. Simulation results show that the low-speed PMSG, which has the skew stator core and fractional slot concentrated winding, has a series of advantages of low cogging torque, high efficiency, small output voltage harmonics and low waveform sine distortion rate, fully meeting the design requirements.
