Electric linear actuators have an output rod that provides linear motion via a motor driven ball screw, lead screw, or ACME screw assembly.

Piezoelectric actuators are devices that produce a small displacement with a high force capability when voltage is applied.

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

Hydraulic linear actuators use a cylinder and hydraulic fluid for motive force

Piezoelectric devices generate electrical signals in response to vibrations and produce mechanical energy in response to electrical signals.

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.
