the winding is sequentially wound on each stator tooth;

the protection end plate is annular and is arranged on one end face of the stator core.

Preferably, a plurality of insertion parts which are arranged along the circumferential direction of the protection end plate at intervals are fixedly arranged on one surface of the protection end plate, and the plurality of insertion parts are respectively inserted into the plurality of stator slots.

Preferably, the protective end plate and the stator core are fixed through ultrasonic welding.

Preferably, the protection end plate and the stator core are fixed through a buckle structure.

Preferably, the protection end plate is made of plastic, and a plurality of hollow holes are formed in the protection end plate at intervals along the circumferential direction of the protection end plate.

Preferably, the hollow holes comprise a plurality of first hollow holes and a plurality of second hollow holes, the first hollow holes and the second hollow holes are alternately arranged along the circumferential direction of the protection end plate, the plurality of first hollow holes are respectively arranged opposite to the plurality of stator teeth, and the plurality of second hollow holes are respectively arranged opposite to the plurality of stator slots.

After the structure more than adopting, compared with the prior art, the utility model, have following advantage:

the utility model discloses a stator module is provided with the protection end plate, like this, after the winding twines on each stator tooth of stator core in proper order, will protect on the end plate is fixed to a terminal surface of stator core, like this, the protection end plate can form spacingly to the winding to put the winding in order on stator core, in order to avoid the winding to tie a knot the winding, thereby avoid taking place the safety problem.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 and 2, the stator assembly of the present invention includes a stator core 10, a winding, and a protective end plate 20.

The stator core 10 includes an annular body 11 and a plurality of stator teeth 12, the plurality of stator teeth 12 are all disposed on an inner wall surface of the annular body 11, one end of each stator tooth 12 is fixedly connected to the annular body 11, the other end of each stator tooth 12 extends inward along a radial direction of the annular body 11, the plurality of stator teeth 12 are disposed at intervals along a circumferential direction of the annular body 11, and a stator slot 13 is defined between each two adjacent stator teeth 12.

The windings are sequentially wound around each stator tooth 12.

Protection end plate 20 be the annular, protection end plate 20 sets up on a terminal surface of stator core 10, like this, after the winding twines in proper order on each stator tooth 12 of stator core 10, will protect end plate 20 and fix to a terminal surface of stator core 10, like this, protection end plate 20 can be spacing to the winding formation in the axis direction to conclude the arrangement to the winding, avoid the winding to tie a knot and twine.

One surface of the protection end plate 20 is fixedly provided with a plurality of insertion parts 21 arranged along the circumferential direction of the protection end plate 20 at intervals, and the plurality of insertion parts 21 are respectively inserted into the plurality of stator slots 13, so that the connection between the protection end plate 20 and the stator core 10 is more stable.

The protection end plate 20 and the stator core 10 are fixed through ultrasonic welding, or the protection end plate 20 and the stator core 10 are fixed through a buckle structure.

The above-mentioned buckle structure specifically means that the edge of the protection end plate 20 is provided with a plurality of buckle elements 24, a plurality of buckle holes 14 are correspondingly formed in the stator core 10, and the plurality of buckle elements 24 are respectively fastened and fixed in the plurality of buckle holes 14, so that the protection end plate 20 is connected with the stator core 10.

Protection end plate 20 make by plastics, be provided with the fretwork hole that a plurality of set up along the circumference interval of protection end plate 20 on the protection end plate 20, because protection end plate 20 is made by plastics, and monoblock plastic slab yielding, intensity are low, so set up the fretwork hole on protection end plate 20 in this embodiment, can strengthen the structural stability of protection end plate 20 for protection end plate 20 non-deformable.

The hollow holes comprise a plurality of first hollow holes 22 and a plurality of second hollow holes 23, the first hollow holes 22 and the second hollow holes 23 are alternately arranged along the circumferential direction of the protection end plate 20, the plurality of first hollow holes 22 are respectively arranged opposite to the plurality of stator teeth 12, and the plurality of second hollow holes 23 are respectively arranged opposite to the plurality of stator slots 13.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention, but should not be construed as limiting the claims, and the present invention is not limited to the above-described embodiments, but may be modified in various ways. In summary, all changes that can be made within the scope of the independent claims of the present invention are within the scope of the present invention.
