Embodiment Construction

[0025] Below again in conjunction with accompanying drawing, the specific embodiment of the application of the present invention is described in further detail:

[0026] As shown in the accompanying drawings, it is an embodiment of the application of the present invention.

[0027] People can make a toroidal stator 1 according to the usual manufacturing method of a disc motor, and make the two sides of the toroidal stator 1 have two annular planes. At the same time, use the inner circle yoke 9 and the outer circle yoke 14 of the stator 1 to forcefully clamp and fix the annular body stator 1 from the inner circle direction of the stator 1 ring body outward and from the outer circle direction inward.

[0028] On the two annular planes on both sides of the annular body stator 1, slots for installing the coil winding 4 and the coil winding 5 are opened respectively, and then the insulating material is put in according to the rules and procedures, and the coil is embedded, and the ...

Abstract

The invention discloses a high-power hub motor power wheel. Because the inner space of a wheel hub is narrow, a high-power motor cannot be installed, and the practical requirement that a pure electricvehicle uses a high-power hub motor power wheel cannot be met. Therefore, one motor stator and two motor rotors are specially designed and adopted to integrally construct the total power output by two rotary electromagnetic field air gap spaces, and the total power is about two times of the output power of one rotary electromagnetic field air gap space, so that the high-power hub motor power wheel is formed. Compared with a power wheel composed of a hub motor with the same power, the high-power hub motor power wheel has the advantages that the size of the motor is reduced, consumption of copper, iron and other materials is reduced, the weight is reduced, and the production and manufacturing cost is reduced; the electric energy consumption of the whole vehicle is reduced; the endurance mileage is increased; and the climbing capacity is improved. High-power hub motor power wheels can be produced on a large scale, and huge requirements of the hub motor power wheel market can be expectedto be met.

Description

technical field [0001] The application of the present invention relates to a method for forming a high-power in-wheel motor powered wheel, which is a design concept and manufacturing technology of mechatronics, and it is possible to design and develop a reliable practical technology for the rapid development and progress of pure electric vehicles. Background technique [0002] The wheels of existing pure electric vehicles do not have power, and most of them rely on the vehicle-mounted electric motor power system to drive the axle to drive the wheels to rotate forward; their cruising range is short, climbing ability is insufficient, control response is slow, ... extremely The earth restricts the progress and development of pure electric vehicles. It was not until January 24, 2018, at the summit forum of the China Electric Vehicles Hundred People’s Association, that the hub drive was publicly admitted that compared with the centralized drive, it is more advanced, energy-saving...
