频繁启停;适合频繁启停和正反转换操作。该系统具有高启动转矩和低启动电流的特点，因此在启动过程中电流冲击小，电机发热小于连续额定运行期间。它适用于频繁的启停和正向和反向转换操作。

性能好;调速性能好。控制开关磁阻电机至少有四种主要运行参数和常用方法：相导角、相关分断角、相电流幅值、相绕组电压，灵活方便。根据电机的运行要求和电机的状况，可以采用不同的控制方法和参数值，使其以佳状态运行（如大输出，率等），还可以实现各种功能。特定曲线。例如，电机具有完全相同的四象限运行能力，具有高的启动转矩和串联励磁电机的负载能力曲线。可用于速度闭环控制，形成非静态速度控制系统可以非常方便。

效率高;开关磁阻电机系统是一种的调速系统。以3kW SRM系统为例，系统效率在宽范围内可以达到87%。
