Electric Motors And Drives

It is important to distinguish between motors and drives. A motor is a mechanical or electrical device that generates the rotational or linear force used to power a machine. A drive is an electronic device that harnesses and controls the electrical energy sent to the motor. The drive feeds electricity into the motor in varying amounts and frequencies, thereby indirectly controlling the motor’s speed and torque.

          There are two types of drives: a standard inverter drive for controlling speed and torque only; a servo drive for controlling speed and torque, and positioning machine components used in applications that require complex motion. Together, a motor and drive form a “drive system.”
