In order to avoid the asymmetrical magnetic pull and electromagnetic noise caused by the magnetic fields with two different pole pairs coexisting in the same motor. The rotor of brushless doubly-fed machine (BDFM) is designed with different pairs of stator primary and secondary windings. The effect of the "pole-to-log converter" directly affects the performance of BDFM. Compared with the high-voltage inverter system, the brushless doubly-fed machine can be used as a common asynchronous motor when the inverter fails, which is very important for those occasions where no shutdown is allowed. But the brushless doubly-fed machine also has the limitation, when the design needs according to the concrete request synthesis consideration. If the speed is increased, the volume of the motor will be greatly increased and the manufacture will be more difficult. In summary, the brushless doubly-fed machine (bdfm) has obvious technical and economic advantages in large-capacity speed control systems with low speed and small range of speed regulation
