组合式永磁同步磁阻电机的转子设计

Design on a Combined Rotor of Permanent Magnet Synchronous Reluctance Machine

用解析法设计了ALA磁阻段的主要参数,提出永磁段与磁阻段两轴线偏转技术,增大了组合式转子等效直轴电感,减小了等效交轴电感,充分利用磁阻特性弱磁,扩大调速范围,提高逆变器的利用率。

The analytical method was used to design the main parameters of ALA reluctance segment. It was proposed that the high-inductance of the reluctance segment could be aligned an appropriate angle with the polar axis of the permanent magnet segment to increase the equivalent direct inductance and to decrease the equivalent quadrature inductance. The field-weakening performance of the reluctance was fully utilised for a wide speed range, the utilization of inverter could be improved, bring up with the feasibility to improve stable performance of the motor
