摘要
针对普通永磁无刷直流电机由于调磁困难而限制了其使用范围这一问题,研究了一种永磁磁极与调磁线圈混合励磁的新型永磁电机.首先给出了该型电机的结构及工作机理,然后对其磁链、反电势、电感等静态特性进行分析和仿真研究,以验证理论的正确性,最后通过样机实验验证了该型电机的可行性.
A novel hybrid excitation brushless motor combining permanent magnet with field windings is proposed, which can weaken or strengthen the magnet flux control by adjusting the field winding current. After presenting the configuration and relevant theory of the hybrid excitation motor, its static state characteristics including flux linkage, back EFM, and inductance are analyzed and simulated to verify the theory. The experimental motor confirmed the feasibility of the novel motor.
