Description

一种二极单、三相永磁发电机的多电压单双层绕组A multi-voltage single-layer winding of a two-pole single-phase and three-phase permanent magnet generator

技术领域technical field

本发明涉及一种永磁发电机，尤其是一种单、三相永磁发电机的多电压单双层绕组。The invention relates to a permanent magnet generator, in particular to a multi-voltage single-layer winding of a single-phase or three-phase permanent magnet generator.

背景技术Background technique

在小型永磁发电机中，单层绕组被广泛采用。单层绕组没有层间绝缘，槽利用率高，便于机械下线，但定子绕组多为整距绕组，电势谐波含量高，转子电压波形畸变率往往大于10%，不满足国际标准要求。国际市场上，对小型永磁发电机不但要求相电压波形畸变率小于5%，还要求单、三相能通用，并且要求有多种接法，满足有多电压等级的要求。In small permanent magnet generators, single-layer windings are widely used. The single-layer winding has no interlayer insulation, the slot utilization rate is high, and it is convenient for mechanical off-line, but the stator winding is mostly full-pitch winding, the potential harmonic content is high, and the distortion rate of the rotor voltage waveform is often greater than 10%, which does not meet the requirements of international standards. In the international market, small permanent magnet generators not only require the phase voltage waveform distortion rate to be less than 5%, but also require single-phase and three-phase common use, and require multiple connection methods to meet the requirements of multiple voltage levels.
