AI Technical Summary
Technical Problem
Existing brake dust capture systems for vehicles with electric traction motors are inefficient and costly due to space constraints, and existing solutions do not adequately address the spread of harmful brake dust particles into the environment.
Method used
A motor vehicle wheel design incorporating a stator with permanent magnets on its external circumferential face, featuring cavities that capture and retain brake dust particles, allowing for efficient and economical brake dust retention without obstructing the wheel.
Benefits of technology
The design effectively captures and retains a large quantity of brake dust particles, preventing their spread into the environment and optimizing space for other components, thus enhancing ecological compliance and vehicle performance.

Abstract
MOTOR WHEEL FOR MOTOR VEHICLE WITH BRAKE DUST PARTICLE CAPTURE The present invention relates to a wheel (4) of a motor vehicle (2), comprising: - an electric motor for driving the wheel in rotation, said electric motor comprising a stator (8) intended to be fixedly connected to a suspension axle of a motor vehicle, and a rotor (10) mounted for rotation relative to the stator and comprising an axis of rotation, said stator being arranged radially internally within said rotor; and - a braking device (16) capable of braking the rotor, notable in that the stator comprises at least one permanent magnet (22) disposed on an external circumferential face (8.1) of said stator, said at least one permanent magnet comprising an external face (22.1) provided with a cavity (24) opening radially outwards towards the rotor, said cavity being configured to capture and retain brake dust particles (26) originating from the braking device. (Figure to be published with the abbreviation: Figure 3).
