Abstract
Aircraft electric motors include a rotor having a plurality of magnet segments arranged on a frame of the rotor, the rotor defining an internal cavity radially inward from the plurality of magnet segments, an output shaft operably coupled to the rotor, and a stator having a support structure and at least one winding wrapped about a plurality of stator teeth. The stator teeth include inner teeth arranged on a radially inward side of the support structure and outer teeth arranged on a radially outward side of the support structure and the stator is arranged within the internal cavity of the rotor. At least one of the inner teeth, the outer teeth, or the support structure is formed from a non-magnetic material with embedded magnetic wires.

An aircraft electric motor comprising:
- a rotor comprising a plurality of magnet segments arranged on a frame of the rotor, the rotor defining an internal cavity radially inward from the plurality of magnet segments;
- an output shaft operably coupled to the rotor;
- and
- a stator comprising a support structure and at least one winding wrapped about a plurality of stator teeth comprising inner teeth arranged on a radially inward side of the support structure and outer teeth arranged on a radially outward side of the support structure, the stator arranged within the internal cavity of the rotor;
- wherein at least one of the inner teeth, the outer teeth, or the support structure is formed from a non-magnetic material with embedded magnetic wires.
An aircraft comprising:
- at least one aircraft electric motor;
- at least one electrical device;
- and
- a power distribution system configured to distribute power from the at least one electric motor to the at least one electrical device,
- wherein the at least one aircraft electric motor comprises:
- a rotor comprising a plurality of magnet segments arranged on a frame of the rotor, the rotor defining an internal cavity radially inward from the plurality of magnet segments;
- an output shaft operably coupled to the rotor;
- and
- a stator comprising a support structure and at least one winding wrapped about a plurality of stator teeth comprising inner teeth arranged on a radially inward side of the support structure and outer teeth arranged on a radially outward side of the support structure, the stator arranged within the internal cavity of the rotor,
- wherein at least one of the inner teeth, the outer teeth, or the support structure is formed from a non-magnetic material with embedded magnetic wires.
