Multipolar double fed induction wind generator with a single phase secondary winding

The project concerns the practical applications of multipolar induction machines as generators for small and medium wind turbines. Such a multipolar generator should be built in a way that the primary and secondary windings are placed on the stator, and the rotor is tooth-like without windings, with each tooth equivalent to one pole pair. The most reliable design is that with a single-phase secondary winding, which provides efficient control of the generator.
