Abstract :
The brushless doubly-fed machine is a machine which incorporates the robustness of the squirrel cage induction machine and the speed and power factor control of a synchronous machine. The electromagnetic environment within the brushless doubly-fed machine is investigated using simple formulae in order to develop an intuitive feel for the mechanism which enables precise speed control of the machine. The concept of cross-coupling from one stator winding to the other via the rotor is described and verified by experiment
