Abstract
A hybrid hysteresis motor is disclosed. The hybrid hysteresis motor includes a stator with, a plurality of axial slots on a first base-end and a plurality of radial slots on an inner surface. The motor further includes an output shaft, a first axial-flux rotor mounted on the output shaft and associated with the stator, and a radial-flux rotor mounted on the output shaft and disposed inside the stator.

A hybrid hysteresis motor comprising:
- a stator comprising:
- a first stator region comprising a first base-end and a plurality of first axial slots disposed along the first base-end;
- a second stator region comprising a second base-end and a plurality of second axial slots disposed along the second base-end;
- a radial slot region comprising an inner surface, a plurality of radial slots disposed along the inner surface,
- wherein:
- the first stator region and the second stator region extending a first distance from an outer edge of the stator from a top perspective and the radial slot region extending a second distance from the outer edge of the stator from the top perspective, the second distance greater than the first distance, and
- the stator comprising ferromagnetic particles enclosed by an electric insulating film;
- an output shaft;
- a first axial-flux rotor associated with the stator, the first axial-flux rotor comprising a steel discoid rotor mounted around a first non-conductive disc holder, the first non-conductive disc holder mounted on the output shaft with an axial air gap extending between the first axial-flux rotor and the first base-end of the stator;
- and
- a radial-flux rotor associated with the stator, the radial-flux rotor comprising a steel annular rotor mounted around a non-conductive ring holder,
- the non-conductive ring holder mounted on the output shaft, the radial-flux rotor disposed inside the stator with a radial air gap extending between the radial-flux rotor and the stator,
- wherein the first axial slots and the radial slots of the stator host a stator winding.
