基于梯形波相电流控制的六相感应电机性能分析

摘要

By using the trapezoidal phase current waveform, the stator winding is separated into the field winding and the torque winding, which can realize direct control of the field and torque without the complex Park transformation. The paper carries on the analytical calculation of the rotor flux linkage and induced voltage as MMF decoupling. The Finite Element calculation and practical measurements are used to verify the rotor induced voltage of the motor. The result of the rotor induced voltage obtained from these methods show good agreements.%六相感应电机通过使用梯形波相电流而把定子绕组分成励磁绕组和转矩绕组,这样可以实现励磁磁场和电磁转矩直接控制而不需要复杂的派克变换,本文主要对磁势解耦时磁链和转子感应电压进行了理论和有限元分析,并实验测量了梯形波相电流驱动下六相感应电机转子感应电压,结果表明转子感应电压的有限元分析和实验结果是一致的.
