WIRELESS IN-WHEEL ELECTRIC ASSEMBLIES WITH INTEGRATED IN-WHEEL COOLING AND VEHICLES CONTAINING THEM

摘要

An in-wheel wireless electric motor assembly having a wheel, an electric motor disposed within the wheel, the electric motor having a stator and a rotor, a receiving coil disposed within the wheel and for receiving wirelessly transmitted power, a first inverter disposed within the wheel, electrically coupled to the receiver coil and serving to convert the wirelessly transmitted energy from the receiver coil to direct current, an inverter circuit disposed within the wheel electrically connected to the converter circuit and the electric motor is and serves to provide the electric motor with power. The in-wheel wireless electric motor assembly further includes a cooling system disposed within the wheel and including: a micropump that serves to pump coolant, a fluid conduit that serves to direct the coolant proximate to the converter circuit and / or the inverter circuit along, and a heat exchanger, which serves to receive heated coolant and dissipate heat to the environment.
