  • Wireless in-wheel electric assemblies with integrated in-wheel cooling and vehicles incorporating the same
    Patent number: 10381901
    Abstract: A wireless in-wheel electric motor assembly having a wheel, an electric motor disposed within the wheel, the electric motor including a stator and a rotor, a receiving coil disposed within the wheel and operable to receive wirelessly transmitted energy, a first converter disposed within the wheel, electrically coupled to the receiving coil and operable to convert the wirelessly transmitted energy from the receiving coil into direct current, an inverter circuit disposed within the wheel, electrically coupled to the conversion circuit and the electric motor, and operable to power the electric motor. The wireless in-wheel electric motor assembly further includes a cooling system disposed within the wheel that includes a micro pump operable to pump coolant, a fluid line operable to pass the coolant proximate at least one of the conversion circuit and the inverter circuit, and a heat exchanger operable to receive heated coolant and dissipate heat to the environment.
