然这种电压的波形也是脉动的，但是由于调制的频率可以达到很高，因此波形仍然可以很好。从上述原理看出，PWM的特点可以使系统的快速性提得很高。如果采用晶体管，其动态调节时间比可控硅快，但允许的电流较小，因此比较适合中、小功率的驱动电路。除了直流进给电机外，FANUC的交流电机也采用PWM控制。交流电机的控制，是通过交流、直流、交流的原理产生交流电压去控制交流电机。

首先电网的交流电压经过整流变成直流电压，供电给逆变器，它把直流磁路，减小低速脉动。这种电机非常适合数控车床和数控齿轮机床的应用。除此以外，FANUC还开发了与机床主轴直连的主轴电机，油冷主轴电机。为了简化变成交流；而逆变器是由PWM控制的，通过PWM电路，变化交流电压的幅值，频率低时，输出电压的幅值也低，频率高时，由于采用PWM的控制，输出电压的幅值也高。这样就达到变频的同时也改变了电压。不但进给驱动系统采用这个原理；而且交流主轴电机的调速也是如此。一般频率为3kHz～10kHz。
