Simulation analysis of permanent magnet motor in high voltage disconnecting switch under different structure and winding parameters

The permanent magnet motor is presented and employed in GIS disconnecting switch in order to reduce the VFTO in operation and enhance the operating performance in motion, which it can achieve the opening and closing operation, have a good quicker response ability and control performance for the disconnecting switch. The mathematical model of motor is developed, which the dynamic behavior is carried out by using the transient finite element method. The speed characteristics of motor are computed considering the different structure and winding parameters of driving motor such as the operating voltage, length to diameter ratio, length of air-gap, thickness of permanent magnet, pole arc coefficient and turns and line width ratio. The results indicate that permanent magnet motor have an excellent performance which can give a sufficient speed to meet the requirements of disconnecting switch. It can provide a base for shorten the design cycle and reduce the performance testing cost of permanent magnet motor which applied in GIS disconnecting switch.
