电压调速法：通过改变电源电压来调节电机的转速。当电源电压增大时，电机的转速也随之增大，反之，电机的转速会减小。

　　电枢调速法：通过改变电枢绕组的接法来改变电机的转速。在串联接法中，将电枢和电源串联，可以使电机的转速随着负载增加而减小。在分流接法中，将电枢和电源并联，可以使电机的转速随着负载增加而增大。

　　磁极调速法：通过改变电机的磁极数来改变电机的转速。当磁极数增大时，电机的转速会减小，反之，电机的转速会增大。

　　负载调速法：通过改变电机的负载来改变电机的转速。当负载增加时，电机的转速会减小，反之，电机的转速会增大。

　　此外，还可以通过在电路中加入调速器来实现电机的调速。常见的调速器包括可调电阻、调压器、PWM控制器等，可以根据具体的调速要求来选择不同的调速器。
