Abstract
A multi-phase motor including a rotor and a stator including at least one core. The stator includes a plurality of phase sections. Each phase section is configured to provide a phase of the multi-phase motor. Each phase section includes at least one of the core(s), at least two ring magnets having polarity facing in a substantially same direction, and a winding between the at least two ring magnets. The winding is configured to be energized to direct flux through the at least one core at a first portion associated with a first one of the ring magnets, and to be differently energized to direct flux through the at least one core at a second portion associated with a second one of the ring magnets.

A multi-phase motor comprising:
- a rotor;
- and
- a stator comprising at least one core, where the stator comprises a plurality of phase sections, where each phase section is configured to provide a phase of the multi-phase motor, where each phase section comprises at least one of the core(s), at least two ring magnets having polarity facing in a substantially same direction, and a winding between the at least two ring magnets, where the ring magnets comprise permanent radially magnetized ring magnets, where the winding is configured to be energized to direct flux through the at least one core at a first portion associated with a first one of the ring magnets and to be differently energized to direct flux through the at least one core at a second portion associated with a second one of the ring magnets.
A multi-phase motor comprising:
- a rotor;
- and
- a stator comprising at least one core, where the stator comprises a plurality of phase sections, where each phase section is configured to provide a phase of the multi-phase motor, where each phase section comprises at least one of the core(s), at least two ring magnets having polarity facing in a substantially same direction, and a winding between the at least two ring magnets, where the winding is configured to be energized to direct flux through the at least one core at a first portion associated with a first one of the ring magnets and to be differently energized to direct flux through the at least one core at a second portion associated with a second one of the ring magnets,
- where a first phase section comprises a first stator member and a second stator member, where a second phase section comprises the second stator member and a third stator member, and where the each stator member comprises a top toothed section and a bottom toothed section.
A multi-phase motor comprising:
- a rotor;
- and
- a stator comprising at least one core, where the stator comprises a plurality of phase sections, where each phase section is configured to provide a phase of the multi-phase motor, where each phase section comprises at least one of the core(s), at least two ring magnets having polarity facing in a substantially same direction, and a winding between the at least two ring magnets, where the winding is configured to be energized to direct flux through the at least one core at a first portion associated with a first one of the ring magnets and to be differently energized to direct flux through the at least one core at a second portion associated with a second one of the ring magnets, where a first phase section comprises spaced top and bottom stator members having the at least two ring magnets and the winding therebetween, where the each stator member comprises an inner toothed section and an outer toothed section facing an opposite direction.
