This paper introduces a design method of line-start permanent magnet synchronous motor (LSPSM). The structure of stator lamination, rotor lamination and stator windings are designed. Finally, the starting process of the motor is simulated by ANSOFT according to its model. By simulation, the distribution of magnetic and the starting performance of motor are presented.
Firstly, the basic principle of space vector pulse width modulation (SVPWM) technology is introduced simply in this paper. Then, simulation model of permanent magnet synchronous traction motor control system is established based on MATLAB/Simulink. The starting and braking characteristics simulation results show that the model is effective, as well as the PI adjuster parameters is appropriate. The...
Now the motors used in pump jacks are usually three-phase induction motors. To meet the requirement for high starting torque, large capacity motors are used. However, since the normal output is only 20-30% of rated power, the efficiency and power factor are low. To overcome this problem, permanent magnet synchronous motor (PMSM) of high efficiency and high starting torque is developed in this paper...
