Description

Technical Field

[0001] The invention belongs to the technical field of hub motors, and in particular relates to a method for dividing copper wires of hub motors. Background Art

[0002] The hub motor is a motor designed by integrating the car's "power system, transmission system, and brake system." The working principle of the hub motor is a permanent magnet synchronous motor. "Wheel-side motor and hub motor" refer to motors installed in different positions on the vehicle. Advantages of hub motors: Advantage 1: Omitting a large number of transmission components, making the vehicle structure simpler; Advantage 2: A variety of complex driving methods can be achieved; Since the hub motor has the characteristic of independent driving of a single wheel, it can be easily achieved whether it is front-wheel drive, rear-wheel drive or four-wheel drive. Full-time four-wheel drive is very easy to achieve on vehicles driven by hub motors.

[0003] As the pressure of energy shortage and environmental problems continues to increase, new energy vehicles have begun to attract attention from all walks of life. New energy vehicles driven by hub motors have gained more and more attention due to their compact structure, fewer transmission parts, and low energy loss. At present, the assembly of motor windings is mostly done manually, generally with two steps: wire splitting and wire winding. Since the two steps are not easy to complete at the same time, the traditional method has the disadvantages of high labor cost, uneven wire splitting, and low labor efficiency.
