This paper introduces the analysis of traction demand for medium-speed maglev trains,and selects the type and design of linear motors.The specific parameters of the hollow Halbach permanent magnet linear synchronous motor for medium-speed maglev train are given by establishing the surface current model.Then by analyzing the influence of different pole pitch,different dimension side length and end ef⁃fect on the motor thrust,the rationality of the motor size parameters is preliminarily verified.Finally,the traction simulation calculation and the model vehicle traction test result demonstrate that the motor meets the train traction demand,which is of great significance for providing reference data for the design and manufacture of the medium speed maglev train linear motor.
