感应电机双馈调速系统是一种性能优越的电力拖动控制系统，它不仅降低了功率 变换器的额定功率，而且能够通过调节转子电压的幅值、相位和频率来实现电机定子 侧功率因数的调节。 -The doubly-fed speed control system of induction motor is a superior performance of the electric drive control system, it not only reduces the rated powe

this examlpe shows how to configure the TIM peripheral in PWM(Pulse Width Modulation mode). the four PWM signals generated with different duty cycles are then fed to the robot CC motor phase. Display menu to choose between different motor speed:
