摘要
工频稀土永磁发电机的气隙磁场是由稀土永磁体提供,具有功率密度大、体积小、结构简单等特点.介绍了单相小功率(4kVA)工频稀土永磁发电机组的设计,通过采样REPMG端电压信号反馈自动调节油机转速,以及采用非均匀气隙长度分布设计永磁发电机的极靴形状,实测样机的性能表明其具有电压波形畸变率和电压变化率小的特点.
Air-gap magnetic field of work-frequency rare earth permanent magnet generator（WFREPMG） is provided by rare earth permanent magnet,has such characteristics as large power density,small size and simple structure.This paper introduce the design on the single-phase small-power（4 kVA） WFREPMG set.By sampling the REPMG voltage signal feedback automatically to adjust the speed of the diesel engines,using non-uniform air-gap length distribution to design the WFREPMG pole shoe shape,the performance of the measured prototype shows that its characteristics with small voltage waveform distortion and small rate of voltage change.
