SR machines can offer a wide variety of aspect ratios and salient pole topologies.

SR机器可能提供各种各样的长宽比和明显杆拓扑结构。

Salient -pole and non-salient pole, unsaturatedand saturated situations are considered.

其中分别考虑了凸极和隐极，不饱和和饱和情况。

Based on the thought of salient pole tracking, the paper studied the application of this method in sensorless control of PMSM in detail.

基于凸极跟踪的思想，详细讨论了高频电压信号注入法在永磁同步电动机无位置传感器运行控制中的应用。
