带阻尼绕组的永磁同步电动机起动分析

Analysis of Jump-start of a Permanent-magnet Synchronous Motor with Damp Resistance

为了改善永磁电机的起动性能,建立了无阻尼绕组和带阻尼绕组两种永磁同步电动机的数学模型方程,并建立它们的模型,在一组参数下对两种永磁同步电动机进行了起动性能仿真,比较分析了带阻尼绕组的永磁同步电动机在起动上的优点。

In order to improve the capability of jump-start for a permanent-magnet synchronous motor, we find two kinds of models of the permanent-magnet synchronous motor without damp resistance and with damp resistance respectively, and simulate a set of design parameter. Compare with permanent-magnet synchronous motor, the merits in jump-start is obtained.
