Design of Linear Motor for Medium and Low Speed Maglev Train

Abstract

Starting from the requirements of medium and low speed maglev vehicles for traction system and the design of traction performance, the characteristics of linear motor are determined through size requirements and power analysis. Through the configuration of typical medium and low speed maglev vehicle traction system, the traction system design of medium and low speed maglev train is gradually developed. The traction characteristics, motor size, motor top-level design parameters and motor performance of the motor are analyzed respectively. Based on the demand of traction characteristics, space size and material cost, a linear induction motor suitable for the maglev train of Qingyuan line in Guangdong is designed. Based on this linear motor, the simulation test is carried out. The experiment shows that this design can meet the requirements of medium and low speed maglev traction.
