Abstract: We propose a new linear oscillatory actuator which converts rotational motion into linear motion using brushed DC motors for Active Control Engine Mounts (ACMs). It was assumed that ACMs using this actuator would be low cost because brushed DC motors can be easily mass produced and the control method has already been established. Finally, we verified the performance of this actuator through FEM analysis, dynamic simulation, and experiments on a prototype.
