Problems solved by technology

[0004] The existing hub motor generally has only one rotor. When the distance between the rotor and the hub is large, the driving force of the hub motor to the hub is small. In order to improve the driving force of the hub motor to the hub, the general method is to reduce the hub motor. The distance between the hub and the hub, due to the reduction of the distance, the friction between the two is greatly increased, which greatly reduces the life of the hub motor

Abstract

The invention discloses a double-rotor or multi-rotor hub motor. The double-rotor or multi-rotor hub motor comprises a motor end closure, a motor shaft, a stator and rotors, wherein a winding set is arranged on the stator; permanent magnets are arranged on the rotors; the stator is arranged inside a hollow internal casing of the rotors; two or more rotors are provided; and a clutch is arranged between the two adjacent rotors. By adopting the structure that two or more rotors are provided and the clutch is arranged between the two adjacent rotors, when in use, two or more rotors can be jointed together to drive a hub to rotate, or one motor or a part of the rotors drives the hub to rotate as required, so that the double-rotor or multi-rotor hub motor is flexible and free to use; and by increasing the number of the rotors, the power of the hub motor increases in a building block way to meet different power demands of an electric vehicle.

Description

technical field [0001] The invention relates to a hub motor, in particular to a hub motor with double rotors or multiple rotors. Background technique [0002] New energy vehicles have now become a forward-looking field in the automotive industry, and the drive technology of new energy vehicles is quite different from traditional internal combustion engine vehicles, and one type of drive technology has great development prospects, which is in-wheel motor technology. [0003] The in-wheel motor is also called the in-wheel motor. Its biggest feature is that the power, rotation and braking devices are integrated in the wheel hub, so the mechanical part of the electric vehicle is greatly simplified. The application of hub motors in electric vehicles can not only improve the efficiency of motor drive, but also greatly simplify the mechanical transmission mechanism, reduce the weight of the vehicle, reduce its transmission and additional losses, that is, reduce costs, save energy a...
