Title:
ELECTRIC MOTOR, GIMBAL AND MOBILE PLATFORM
Document Type and Number:
WIPO Patent Application WO/2024/113284
Kind Code:
A1
Abstract:
An electric motor, a gimbal and a mobile platform. The electric motor comprises: an electric motor shaft; a radial flux electric motor assembly, which comprises a rotor assembly and a stator assembly arranged in a radial direction of the electric motor shaft, wherein the rotor assembly and the stator assembly are both sleeved on the electric motor shaft and arranged spaced apart from each other; and a magnetic gear assembly, wherein the magnetic gear assembly and the rotor assembly are sleeved on the electric motor shaft in the radial direction of the electric motor shaft, alternatively, the magnetic gear assembly and the rotor assembly are sleeved on the electric motor shaft in an axial direction of the electric motor shaft, the magnetic flux of the magnetic gear assembly being distributed in the radial direction of the electric motor shaft. The magnetic gear assembly comprises a torque input member and a torque output member, wherein the torque input member is mechanically coupled to the rotor assembly; the torque output member is fixedly connected to the electric motor shaft; and transmission between the torque input member and the torque output member can be achieved under the action of a magnetic field. The stator assembly can drive the rotor assembly to rotate at a first speed, such that the electric motor shaft rotates at a second speed under the action of the magnetic gear assembly, the second speed being smaller than the first speed.
