ABSTRACT:
A permanent magnet direct current machine is provided. The rotor has permanent magnets acting as poles for feeding magnetic flux to the stator. The stator has a multiplicity of "slot paths". Each slot path has as many slots as there are poles on the rotor and also has as many coils as there are poles on the rotor. The coils of a slot path are equally spaced around the axis of the machine and each coil of the slot path is wound through two slots. The coils of a slot path may be switched from series to parallel to hybrid relationships to vary the operating characteristics of the machine.
