Motor starters and contactors are motor-starting devices.

DC motors are most commonly used in variable speed and torque applications.

DC motor starters combine a controller (most often a contactor) with overload protection, allowing a motor or motor-controlled equipment to be turned on and off

Gearmotors consist of an AC or DC motor with an integral gearbox or gear head that steps delivered speed up or down.

Motor controllers receive supply voltages and provide signals to motor drives that are interfaced to motors.

AC motors include single, multiphase, universal, induction, synchronous, and gear motors.

Servo drives provide electrical drive outputs to servo motors in closed-loop motion control systems where position feedback and corrective signals optimize position and speed accuracy.
