[0002] With the rapid development of the motor technology of electric two-wheel vehicles, the definition of electric two-wheel vehicles by customers has changed from the original "able to ride, easy to ride" to "fun, good-looking, easy to ride". In this environment, the requirements for the performance of motors are further improved. The motor should not only start quickly but also have a large rotational torque. However, due to the influence of the stator core structure in the prior art, the filling rate of the wire embedding grooves on the stator core for installing copper wires is relatively low, resulting in limited rotational torque of the motor and affecting the service performance of the motor, which needs to be improved.

[0006] The copper wire is pre-sleeved on the wire sleeve through the wire embedding area, and through the clamping fit between the wire sleeve and the straight teeth, the copper wire can be quickly fixed on each straight tooth, thereby improving the installation density of the copper wire on the stator core and improving the service performance of the motor.
[0007] Preferably, in the above-mentioned inserted wire embedding structure for a motor, a buckle is arranged on the wire sleeve, a locking convex ring extending in the height direction is arranged on the stator core, and the locking convex ring is inserted between the buckle and the wire sleeve and is in clamping fit.
[0008] The fixing of the height direction of the wire sleeve is realized through the clamping fit between the buckle and the locking convex ring, and the stability of the wire sleeve sleeved on the straight teeth is improved.
[0009] Preferably, in the above-mentioned inserted wire embedding structure for a motor, the number of both the buckle and the locking convex ring is two, the buckles are symmetrically distributed at the upper end and the lower end of the wire sleeve, the locking convex rings are arranged on the upper surface and the lower surface of the stator core, and the locking convex rings are respectively inserted between the corresponding buckles and the wire sleeve.
[0010] The number of buckles and locking convex rings is both set to two, which increases the fixing area of the wire sleeve and the stator core, and further improves the stability of the wire sleeve fixed on the stator core.
[0011] Preferably, in an insert-type wire embedding structure of an electric motor described above, a tooth groove is formed between adjacent straight teeth, and both sides of the wire sleeve are respectively inserted into adjacent tooth grooves, and the side ends of adjacent wire sleeves are in contact with each other.

[0025] Preferably, the wire sleeve 3 is made of nylon PA66 material.
[0026] Specifically, when assembling the wire sleeve 3 on the stator core 1, first wind a copper wire of appropriate specification around the wire embedding area 32, then align the sleeve cavity 31 with the straight teeth 2, and move the wire sleeve 3 towards the straight teeth 2 until the straight teeth 2 are inserted into the sleeve cavity 31. The locking ring 5 is inserted between the snap fastener 4 and the wire sleeve 3 and is in contact with the inner surface of the snap fastener 4. At this time, the assembly of the wire sleeve 3 and the stator core 1 is completed. Through the clamping cooperation between the wire sleeve 3 and the straight teeth 2, the copper wire can be quickly fixed on each straight tooth 2, thereby increasing the installation density of the copper wire on the stator core 1 and improving the performance of the motor.
