Hybrid Actuator

Internal research


A new linear hybrid actuator for active force cancellation was developed.

In precision machines vibration isolation systems isolate the machine components from the surroundings. For suppressing the reaction forces originating in the positioning systems of the machine itself a novel actuator is developed.



  • Realization of an actuator with low stiffness, high force density and low power dissipation
