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

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

DC motor drives act as the interface and power supply between a motion controller and a DC motor

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

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

Stepper motors use a magnetic field to move a rotor in small angular steps or fractions of steps.

DC servomotors are generally small and powerful for their size, and easy to control.
