Magnetic Field Modeling and Analysis of U-Shaped Ironless Permanent Magnet Synchronous Linear Motor
摘要
Abstract
Due to the influence of the core breaking,the traditional iron core linear motor had the end-effect of lateral and vertical side,which made the output of the thrust line fluctuate greatly.The ironless permanent magnet synchronous linear motor has the advantages of zero slot effect,simple structure and flexible control.Based on the analysis of air gap magnetic field ironless permanent magnet synchronous linear motor problems by using two kinds of analytical method,namely equivalent magnetic potential method and the equivalent magnetizing current method,and the finite element analysis of the magnetic field using the finite element method.The analytical method for magnetic field analysis was verified to be accurate.By changing the motor parameters,the optimization design was achieved,which provided the reference for the design and analysis of same kind of motors.关键词
