（a）供给电流时，Q1和Q4导通，电机接通电源。等效短接电机两个引脚的方法有两种。（b）在电流再生1的电路中，在（a）的状态下将Q1关断，断开与电源的连接，使Q2导通，Q4保持导通，将电机的引脚间短接。（c）在电流再生2的电路中，同样将Q1关断，但Q2保持关断，Q4也保持导通，电机电流经由Q2的寄生二极管循环流动。 图2为使用了这种将电机的两个引脚端接的电流再生方法时的PWM工作波形。作为等效电路，（b）和（c）基本相同，所以波形也相同。为了更容易理解，电流波形峰值之间的变化绘制得比实际要大。 

时间t为∞，即当电机发电电压（Ec）为零时，稳定状态的电机平均电流值Iave如下： Iave＝Ea･m/R  ※Ea：电机电源电压，m：导通占空比，R：电机等效电阻 因此，电机电源电压Ea乘以导通占空比m而获得的电压被施加到电机。
