| Abstract |
For high power industrial applications requiring high dynamic performance and a large fieldweakening range, the double fed wound rotor asynchronous motor (DFAM) offers an interesting solution. Due to the high flexibility of the DFAM (four degrees of freedom) flux, torque, rotorfrequency and powerfactor can be controlled independently. The observability of the rotorcurrents and the better field distribution of the wound rotor induction motor as compared with cage induction motors, allows for a more precise open loop torque control. This paper describes an indirect vector control strategy for induction motors fed by two IGBT PWM inverters. Experimental results are included. |
