UNA MAQUINA DE CORRIENTE ALTERNA DE M FASES.

摘要

A multiphase electric machine whose stator winding is disposed in an air gap between a smooth stator wall and the rotor. The coils of the stator winding are wound stepwise in such a way that per coil the field variation in the direction of movement of the rotor is substantially sinusoidal and the winding has a constant thickness.
