    Abstract: An electrical machine system includes a stator having a conical stator surface defining a rotary axis. A rotor is operatively connected to the stator for rotation relative thereto, wherein the rotor includes a conical rotor surface. A conical gap is defined between the conical surfaces of the stator and rotor about the rotary axis. An actuator is operatively connected to at least one of the stator and rotor for relative linear motion along the rotary axis of the stator and rotor to change the conical gap, wherein the actuator provides relative linear motion between a first position for a first conical gap width and a second position for a second conical gap width different form the first conical gap width. In both the first and second positions the full axial length of one of the rotor or stator is axially within the axial length of the other.

    Abstract: A phase separator for an electrical machine includes a first end portion, a second end portion, and a midsection. The midsection connects the first end portion to the second end portion such that the first end portion opposes the second end portion. The midsection is configured for fixing the phase separator in the electrical machine for separating the adjacent phase windings from one another. The first and second end portions are for separating end turns of adjacent phase windings of an electrical machine.

    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.
