Controlling the Speed of the Motor
... An electric motor is a device that converts electric current (AC or DC) into rotary motion. The speed of a DC motor varies with the voltage applied to the terminals – higher voltage results in higher speeds. This suggests a simple way to control the speed of a DC motor: simply raise the voltage if w ...
