Abstract
Aircraft electric motors include a rotor having magnet segments arranged on a frame of the rotor, the rotor defining an internal cavity radially inward from the magnet segments. An output shaft is operably coupled to the rotor and a stator, having a yoke and at least one winding wrapped about stator teeth, is arranged within the internal cavity of the rotor. The stator defines a radial span as a distance from the yoke to a radial outward edge of the at least one winding. The plurality of stator teeth have at least one tooth formed from a magnetic material with the tooth having an engagement end configured to engaged with the yoke, a distal end opposite the engagement end, and a shaped end at the distal end of the tooth, with a portion of the tooth at the shaped end being closer to the yoke than the radial span.
