This paper presents a practical approach of FEA modeling and optimization of the design of the compact electromagnetic actuator. This special actuator is designed to perform the gear shifts in the synchronized segmentally interchanging pulley transmission system (SSIPTS.) The geometry and material properties of the actuator, which are confined by the assembling space and running condition of SSIPTS, are parametrically optimized by using FEA package, Comsol Multiphysics. The current density of coil, the geometric parameters of magnet, and the permeability of structural materials are major control variables in the optimization of the novel actuator. The target of the optimization process is to find the maximum electromagnetic force and the minimum mass of the entire device within the available space in the transmission package. The simulation results for the optimized design are presented and further compared with the performance requirements of the actuator.
