Thrust for Permanent Magnet Linear Synchronous Motor

In order to increase the traction efficiency and driving speed of low-speed maglev train, synchronous traction technology is applied to low-speed maglev train. In order to reduce the normal force of the motor and enhance the stationarity of traction, the motor is designed with air-core coil as primary and permanent magnet Halbach array as secondary. Through theoretical analysis, the analytical expression of motor thrust and normal force is concluded and the thrust of motor is measured on the basis of a certain permanent magnet linear synchronous motor test platform. The effectiveness of the analytical method is verified by means of the measurement result accordingly
