Abstract :
A novel WRLS-PMSM (wound rotor line-start permanent magnet synchronous motor) with WMW (weak magnetic winding) on rotor is proposed in this paper. The WMW installed under the starting winding is to restrain the braking torque of PMSM in the process of starting. Mathematical model of WMW and magnetic circuit is established. In order to do simulation analysis of this type of motor, a prototype of 22kw is designed. This paper analyzes the weak magnetic effect of WMW when its main dates change such as number of turns and wire gauge. The analysis results and mathematical model can provide the basis for design. This paper does research in the induced voltage and weak magnetic current change rule of WMW under the diode of single guide using the FEA method. This paper also studies the relationship between the specific dimensions of starting winding on rotor and performance parameters, for example, starting torque, generating and braking torque, pull-in torque, starting current, etc. Study the relationship between external series resistance and asynchronous torque. Study the difference of asynchronous torque when magnetic circuit structure is symmetrical or not.
