Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, and in particular to a winding device for an external rotor of a motor. Background Technology

[0002] In the motor manufacturing process, the winding operation of the outer rotor is a key step that directly affects the performance and reliability of the motor. Existing winding equipment usually places the outer rotor on the outside of the fixed shaft, and the motor drives the fixed shaft to move closer to the winding unit, which then winds the wire around the outside of the outer rotor.

[0003] However, the fixed shaft and the middle part of the outer rotor are fixed by mutual contact friction. During the rotation of the outer rotor, the frictional restraint force of the fixed shaft on the outer rotor in the vertical direction is reduced, which makes the outer rotor prone to vertical positional displacement. This not only affects the uniformity and tightness of the winding, but may also cause faults such as wire breakage or short circuit during the winding process. In order to solve the above problems, this utility model proposes a winding device for the outer rotor of a motor. Utility Model Content
