MOTOR
A motor converts electrical or chemical energy into mechanical energy.
Electric motors are commonly used in robots. They can operate from
alternating current (AC) or direct current (DC), and can turn at a wide
range of speeds, usually measured in revolutions per minute (rpm) or revo-
lutions per second (rps). Motors range in size from the tiny devices in a
wristwatch to huge, powerful machines that can pull a train.
