DUAL-ROTOR HUB MOTOR BASED ON AXIAL MAGNETIC FIELD AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/160426
Kind Code:
A1
Abstract:
Disclosed in the present invention are a dual-rotor hub motor based on an axial magnetic field and a control method therefor. The dual-rotor hub motor based on the axial magnetic field comprises a wheel axle and a hub; the wheel axle is fixedly connected to a vehicle frame; the hub relatively rotates by using the wheel axle as a center; a disc-shaped middle stator is fixedly connected to the wheel axle; a left coil assembly and a right coil assembly are respectively and fixedly mounted at the two sides of the middle stator; a left rotor and a right rotor are arranged at the two sides of the middle stator; the left coil assembly drives the left rotor to rotate, and the right coil assembly drives the right rotor to rotate; and a left clutch is provided between the left rotor and the hub, and a right clutch and a deceleration mechanism are arranged between the right rotor and the hub. The present invention has the following beneficial effects: the present invention can satisfy the requirements of variable working conditions during actual driving of a vehicle, and two motors both can work at high efficiency, so that the energy consumption of a whole vehicle can be reduced; the mounting spaces of the left and right clutches are optimized, the axial size of the motor is reduced, and the weight is reduced.
