A method for winding a motor rotor

Abstract

A motor rotor winding method is provided. A motor rotor comprises a rotor rotary shaft, and an insulation sleeve and a coil sleeved on the rotor rotary shaft. A communicator and a bobbin are sequentially provided around the insulation sleeve. A magnetic pole group is mounted on an outer side surface of the bobbin. Eight wire through-slots are sequentially disposed around the circumference of the bobbin and are sequentially numbered N1, N2, N3, N4, N5, N6, N7, and N8 around the bobbin circumference. Eight copper hooks are sequentially disposed along the circumference of the communicator and are sequentially numbered P1, P2, P3, P4, P5, P6, P7, and P8 around the communicator circumference. An included angle between an armature stacking centerline (1) and a corresponding communicator centerline (2) is 4.5° to 8.5°. The communicator centerline (2) is near to a left pole end of the rotor. Slot-crossing is performed twice, and each instance of hook winding requires two instances of slot-crossing, so that motor rotor winding resistance is evenly distributed, and motor stall torque error is relatively low, thereby reducing energy consumption of a motor and extending service life of a motor.

Description

technical field [0001] The present disclosure generally relates to the field of auto parts, and in particular to a method for winding a motor rotor. Background technique [0002] As people have higher and higher requirements for the safety, comfort and reliability of automobiles, the design of the door accessories, which are the main accessories of the car body, is the key to the design of the car door. Automobile door and window glass not only needs to ensure that the driver has enough viewing angles to drive and drive safely; at the same time, in order to meet the needs of riding comfort, the position of the glass often needs to be adjusted, so the range of glass adjustment and the flexibility and convenience of manipulation become important performances. index. The mechanism that ensures the flexible adjustment of automobile glass is the glass regulator, which is also an important part of automobile safety and comfort. [0003] The micro motor is the heart of the automo...

Problems solved by technology

[0003] The micro motor is the heart of the automotive window regulator. At present, the increase of the stall torque deviation of the motor leads to the increase of the power consumption of the motor and the shortening of the life of the motor. This problem has always existed in the manufacture and use of the motor. The reason is still due to the resistance of the motor rotor winding. caused by uneven
