The most common technique used to vary the applied voltage is called **Pulse Width Modulation (PWM)**, where constant amplitude voltage pulses of varying widths are provided to the motor - the wider the pulse, the more energy transferred to the motor. ​If The frequency of the pulses is high enough that the motor’s inductance averages them, and it runs smooth. + The Brushed DC motor is the simplest type of motor to control, all that needs to be done is to vary the supply voltage and the motor'​s speed will vary proportional to the voltage.
