  3. Abstract:
  4. Brushless Doubly fed machines have two stator windings and an especial cage rotor. The main advantage of the machine is higher reliability in compare with DFIGs. Cross coupling is the mechanism, which provides indirect coupling of the two stator windings. In this paper, time and space harmonics in a BDFM are studied to find a criterion for evaluating different rotor designs and better cross coupling, based on the space harmonics. Then the equivalent space and time harmonic circuits are established, using basic equivalent circuit. Finally, the effects of these harmonics on the torque-speed characteristic are studied
