Technical Field

The invention relates to the technical field of motors, in particular to a concentric type electronic winding two-layer wire inlet mode.

Background

The traditional wire-entering mode of the concentric stator winding is a three-layer type, the three-phase winding is named A, B, C as an example, the three-phase winding is A, B, C three-phase coil from outside to inside, when the three-phase winding enters the first layer of coil, the outside is not interfered, when the three-phase winding enters the second layer of coil and the third layer of coil, the interference of the first layer of coil and the second layer of coil is received, the end parts of the A-phase coil and the B-phase coil need to be extruded forcefully, and space is provided for embedding the coils. Because the coil end is squeezed, the insulation of the slot at the slot opening of the stator is easily broken, the voltage resistance of the motor to the ground is poor, and meanwhile, the wire inlet mode has low efficiency and high rework rate, so that the development of a more convenient wire inlet mode is needed to solve the problems.

The Chinese invention patent is disclosed, the publication number is: CN103414271A, patent name: permanent magnet brushless DC motor and stator winding method, application date: 20130607 which discloses a stator winding method and a permanent magnet brushless dc motor. The two stator winding methods provided by the invention can realize different functions, wherein one winding method enables the motor to obtain large torque at low rotating speed, and the other winding method enables the motor to obtain small torque at high rotating speed. The invention realizes the conversion between low rotating speed, large torque, high rotating speed and small torque of the same type of motor by different winding modes, improves the production efficiency, reduces the production cost, enriches the functions of the motor and ensures that the motor can be applied to different occasions.
