アクティブコントロールエンジンマウント用電磁アクチュエータの開発

抄録

　Linear oscillatory actuators using a DC motor converts a rotational motion into a linear motion. The actuator we previously proposed is difficult to assemble and its armature sometimes can collide with the rotor during operation because the armature is sandwiched between two rotors. In this study, we propose a linear oscillatory actuator that has a new structure. The new structure of this actuator solves the above problems because the armature is inserted inside the rotor. Also, we verified that the performance of the new actuator is equivalent to the previous model through FEM analysis and dynamic simulation.
