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.

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

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.

Potentiometers, rheostats and trimmers are three-terminal resistors that are used to measure or divide voltages, and to protect or control circuits.

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