SYSTEM FOR IMPROVING LINEAR SYNCHRONOUS MOTOR MOMENTUM OF ULTRA-HIGH SPEED RAILWAY TUBE TYPE TRAIN PROPEL

摘要

PURPOSE: A module phase set shift application system is provided to reduce an average value of a cogging force ripple by modularizing a linear synchronous motor field magnet consisting of a plurality of poles. CONSTITUTION: An LSM(Llnear Synchronous Motor) wounded type movement field magnet(10) is composed of a first LSM field magnet module(11) and a second LSM field magnet module(12) to n LSM field magnet module(1n). The first LSM field magnet module and the second LSM field magnet module to n LSM field magnet module are separated as pole pitch. A LSM three phase armature coil(22) is installed in the ground of the lower side of the LSM wounded type movement field magnet. The LSM three phase armature coil comprises an LSM three phase armature core(21) and a plurality of LSM three phase armature coils(22) included on the upper side of the LSM three phase armature core.
