摘要
内置式永磁同步电机电抗参数无论对电机的电动运行性能还是发电运行性能都有着重要影响。首先分析了磁钢成V型排列的内置式永磁同步电机的电抗特性,计算得到了不同转子结构的电抗参数,总结了该种结构的永磁同步电机电抗参数随磁钢结构的变化规律,然后分析了不同磁钢结构即不同凸极率下内置式永磁同步电机的外特性变化规律,并解释了发生变化的原因。
The reactance parameters of internal permanent magnet synchronous motor have important impact on the working performance. This paper firstly analyzed reactance characteristics of the internal V-shaped permanent magnet synchronous motor, and calculated the reactance parameters of different rotor structures, the variation in reactance parameters of rotor structures of the permanent magnet synchronous motors was determined, and then analyzed the the working performances of different salient pole rates.
