A Linear Electromagnetic Actuator with Three Holding Points for Gear Shift Unit

Gear shift mechanisms using linear electromagnetic actuators (LEAs) can change gears without mechanical fiction. However, they need a large amount of power consumption to hold required positions. In order to solve this problem, we propose a novel LEA for the gear shift unit. The proposed LEA can hold a gear contact at three points by the detent force. In this paper, the characteristics of the proposed actuator are verified using a three-dimensional finite element method.
