Abstract: An electric machine having a thermal management system includes a stator having a stator core, and a rotor having a rotor core that is moveable relative to the stator. At least one of the stator and the rotor include one or more windings. One or more coolant cans encapsulate one or more of the windings disposed on the at least one of the stator and the rotor in an interior compartment of the coolant can. The interior compartment of the coolant can defines a coolant flow passage through the one or more windings. The coolant can includes a coolant inlet and a coolant outlet in fluid connection with the interior compartment of the coolant can. The interior compartment of the one or more coolant cans are fluidically isolated from the stator core and the rotor core.

Abstract: An electric motor has a stator defining multiple stator poles with associated electrical windings, and a rotor having multiple rotor poles. The rotor has flux barriers between adjacent rotor poles, the flux barriers each having a material with an electrical conductivity higher than the rotor pole material. The flux barriers are electrically isolated from one another external to the ferromagnetic material. Eddy currents are induced in the flux barrier to cause destructive interference of an impending magnetic field, such that the flux barrier effectively acts to inhibit magnetic flux during motor operation, which in some cases will result in a repulsive force that will act to increase an induced motive force on the rotor poles.

Abstract: An electric motor has a stator mechanically coupled to the rotor by a nutating traction interface, such that during nutation of the rotor with respect to the stator a tilt axis of the rotor progresses about the axis of rotation of the output shaft. The rotor and a surface of the stator bound a dynamic gap across which a magnetic field is produced by electrical activation of the motor to generate a force between the rotor and the stator. The traction interface and the gap are arranged such that, in a plane containing the axis of rotation of the output shaft, the traction interface is angled with respect to the stator surface bounding the gap. The rotor is connected to the output shaft by a tiltable connection such as a gimbal.
