Rotor-Wheeled Motor Assembly With Integrated Inverter and Cooling Device for Electric Vehicles - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240051404 titled 'Rotor-Wheeled Motor Assembly With Integrated Inverter and Cooling Device for Electric Vehicles
Simplified Explanation
The abstract describes a rotor-wheeled motor assembly that includes a wheel with a rim and an interior region. The rim has a tire mounting surface and an interior radial surface. An electric motor is disposed within the interior region and includes a rotor embedded into the tire mounting surface. The rotor rotates in unison with the tire mounting surface. A stator assembly with stator windings opposes the rotor, creating an axial flux air gap between them.
- The assembly includes a wheel with a rim and an interior region.
- The rim has a tire mounting surface and an interior radial surface.
- An electric motor is embedded within the interior region.
- The motor includes a rotor that rotates with the tire mounting surface.
- A stator assembly with stator windings opposes the rotor.
- The opposition creates an axial flux air gap between the rotor and stator windings.
Potential Applications:
- Automotive industry: This technology can be used in electric vehicles to provide a compact and efficient motor assembly.
- Robotics: The rotor-wheeled motor assembly can be utilized in robotic systems that require compact and powerful motor systems.
- Industrial machinery: The assembly can be integrated into various industrial machinery to provide efficient and reliable motor functionality.
Problems Solved:
- Compact design: The rotor-wheeled motor assembly offers a compact design by embedding the motor within the wheel, saving space and reducing the overall size of the motor assembly.
- Efficient power transmission: The axial flux air gap between the rotor and stator windings allows for efficient power transmission, resulting in improved motor performance.
- Simplified installation: The tire mounting surface of the rim allows for easy installation of the wheel onto a vehicle hub assembly, simplifying the assembly process.
Benefits:
- Space-saving: The compact design of the assembly saves space, making it suitable for applications where size is a constraint.
- Improved efficiency: The axial flux air gap and efficient power transmission result in improved motor efficiency, reducing energy consumption.
- Easy installation: The tire mounting surface of the rim allows for easy installation onto a vehicle hub assembly, saving time and effort during assembly.
Original Abstract Submitted
a rotor-wheeled motor assembly includes a wheel that includes a rim coaxial with an axis of rotation of the wheel and circumscribing an interior region of the wheel. the rim has a tire mounting surface and an interior radial surface on an opposite side than the tire mounting surface and opposing the interior region. the tire mounting surface is configured to mount the wheel to a vehicle hub assembly. an electric motor is disposed within the interior region and includes a rotor disposed on or embedded into the tire mounting surface. the rotor is configured to rotate in unison with the tire mounting surface about the axis of rotation along a plane perpendicular to the axis of rotation. a stator assembly includes a stator core and stator windings. the stator windings axially oppose the rotor to define an axial flux air gap separating the rotor and the stator windings.
