Problems solved by technology

[0006] The first solution, on the premise of meeting the performance requirements of the motor, two sets of coils of copper wires with different wire diameters are wound in the slot, the depth of the slot is not enough, the coil in the slot is too full, and the outer edge of the coil is close to the wire. It is not allowed to extend the slot or extend to the outside of the slot. First, it is impossible to install the power supply lead wire on the coil frame, which cannot be implemented in the production process. Electric arc, there are potential safety hazards, and the third is that there are three technical problems that exist in traditional double coils
[0007] In the second solution, the two sets of coils are made of thin copper wires, but it cannot meet the performance requirements of the motor. The performance requirements of the motor are an important indicator for the motor purchasing enterprise to purchase the motor. Whether the motor purchasing enterprise Will purchase motors that do not meet performance requirements
