摘要
从组合式ALA+PM转子同步电机的基本特征和弱磁性能出发,讨论永磁段相对转子全长KPM对电机性能的影响。在样机的扩速范围为3.18倍基速时,KPM应取0.7。仿真结果证明了从电机恒转矩运行性能和恒功率运行性能来确定KPM是合理的。
Based on the basic characteristic and the field-weakening performance of the combined ALA＋PM rotor synchronous motor, the effect of the length KPM of surface permanent magnet （PM）part with respect to the full- length of the rotor exerts on the performance of the motor is discussed. KPM can be 0.7 when the speed range of the prototype is 3.18 times with respect to the base speed. The simulation results show that it is reasonable to confirm KPM value form the operation performance of the constant torque and the constant power.
