Abstract: An induction motor includes a stator defining stator inner and outer diameters extending about a longitudinal axis, the stator includes a plurality of windings extending longitudinally and circumferentially between the stator inner diameter and the stator outer diameter and passing an electric current therethrough to create a magnetic field, a rotor extending along the longitudinal axis having a rotor outer diameter less than the stator inner diameter, the rotor rotates about the longitudinal axis relative to the stator in response to the magnetic field, and a stator thermal exchanging fluid circuit extending both through and about the stator whereby the stator thermal exchanging circuit exchanges thermal energy with the stator.

Abstract: A sliding spoke rotor to hub attachment is provided. The hub is rotatably positioned about a stationary axial shaft. The hub includes a plurality of outwardly radiating spokes. The rotor includes a socket disposed between an end of said spoke and the rotor. The socket slidingly engages the end of the spoke in a radial direction.

Abstract: The present invention is an energy storage apparatus for an automotive vehicle. The energy storage apparatus includes a rotor, a stator, and a hub rotatably positioned about a stationary axial shaft. The hub includes a plurality of spokes radiating outwardly from the hub. A socket is disposed between an end of the spoke and the rotor to slidingly engage the spoke end in a radial direction. A middle layer having an adhesive on both sides is intraposed between the socket and the rotor.
