Simulation of the dynamic behavior on two stator winding structures of motor operating mechanism for high-voltage disconnecting switch

The structure and parameters of the motor used in the operating mechanism is designed according to the characteristics requirement of disconnecting switch. The two kinds of stator winding structures, one of which is stator winding symmetric distribution and the other one of which is stator winding asymmetric distribution, are proposed in the motor design. The dynamic simulation is achieved by using the finite element method according to the two kinds of stator winding structures. The simulation results verify the reasonable of motor design and gain the characteristic curves (torque, current, revolution and angle, etc.). The analysis results indicate that both of the two stator winding structures motor have an excellent performance which can give a sufficient opening or closing speed to meet the requirements of disconnecting switch.
