A servo motor using a PWM control signal needs a pulse width with a duty cycle from 10% to 20% for the full control range and a signal period of 5 milliseconds. What is the minimum and maximum pulse widths required for the full control range? Not enough information. 1 millisecond to 2 milliseconds. 50 microseconds to 500 microseconds. 500 microseconds to 1 milliseconds.

Speed control of motor

Speed control by DC motor-speed controller is required to realize variable speed drive. Whenever a motor drives a particular load, it is called drive, and variable speed drive refers to a load requiring variable speed. All this is obtained by a DC motor speed controller.
