Short-stroke actuators are used to realize short piston strokes up to 0.2 mm with a simply designed actuator. Compact Dynamics has developed an actuator with extremely shot switching times especially for usage in injection valves. When the stator is energized, the rotor will be lifted and when the current is switched off, the rotor will be released.

Linear motors are provided for larger piston strokes.
A rotor is sliding in guides and can be designed for high movement speed, high precision in the hold position or very high forces. There are hardly limitations of the length of the piston stroke.
Compact Dynamics designs the linear motors according to requirements of the customers.
Linear motor are therefore used in a wide range of applications.
