The simple circuit was designed using a 555 timer and pulse width modulation for controlling the speed of DC motor. The pulse width modulation (PWM) pertains to the process of switching the power ...

Using pulse outputs from a PLC is a cost-effective way to get simple motion. Most, if not all, PLC manufacturers provide a way to control servos and steppers using a pulse train signal. So when a ...

Getting step motors up to speed has never been a problem. Getting them to stop is a different matter. Step motors (because of their magnetodynamics) are naturally springy, so they tend to vibrate at ...
