Abstract: Steady state performance is studied for brushless doubly-fed machines. The frequency of every winding is converted to the same value by application of the frequency-conversion method. Equivalent circuit and the phasor diagram can be made. The phasor diagram can be used to analyze the effect of control winding current on power winding. Electromagnetic torque and power equation are alsoused for determining the steady state performance of brushless doubly-fed machines.
