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.

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

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

Hydraulic rotary actuators use a pressurized, incompressible fluid to rotate mechanical components.

Electrohydraulic valve actuators and hydraulic valve actuators convert fluid pressure supply pressure into motion

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