Design and analysis of a Limited angle torque motor with Dual Halbach Arrays

This paper present a new design of a Limited angle torque motor (LATM) with Dual Halbach Arrays for rotary direct drive valve (DDV), which needs high frequency response, high power to weight ratio. Reluctance model of proposed LATM is discussed. The structure parameters are optimized by particle swarm optimization (PSO) method to improve performances… (More)
