WIPO Patent Application WO/2023/113025
Kind Code:
A1
Abstract:
Provided is an in-wheel motor that makes it possible to prevent magnet demagnetization due to the influence of heat from a friction brake. This in-wheel motor is an outer rotor-type in-wheel motor comprising: a stator which includes coils; and a rotor which includes magnets facing the coils and which rotates around a motor shaft with respect to the stator. The rotor includes a rotor case which holds the magnets, and further includes a brake disc which is connected to a wheel-width-direction inner end of the rotor case and which rotates together with the rotor case. The rotor case and the brake disc are connected to each other through a heat capacity member.
