Tubular Permanent Magnet Linear Synchronous Motor Thrust Fluctuation Optimization

Abstract

The thrust fluctuation optimal design of the tubular permanent magnet linear synchronous motor is the key to sinusoidal flux density wave degree in theoretical analysis. And the paper analyses the law of different parameters on the flux density waveform. The axial magnetized linear motor is optimized. The measures which inhibited thrust fluctuation is obtained. It has guidance action in motor designing. It has practical engineering value.
