Description

Technical Field

[0001] The utility model relates to the field of motor windings, in particular to an integrated structure of a motor winding. Background Technique

[0002] A motor winding refers to a coil that fixes a conductive coil at a specific position to create a magnetic field. It is the core component of a motor and plays a crucial role in the normal operation of the motor. The main principle of the motor winding is based on Ampere's force and Faraday's law of electromagnetic induction.

[0003] In the prior art, the tooth poles and the stator core are integrally cast, and the spacing between multiple tooth poles is very small. When installing the winding, tools are needed to press the winding between two tooth poles. Also, when performing winding maintenance or replacement, tools are required to remove the winding, which takes a long time and has a cumbersome process, resulting in a reduced disassembly and assembly efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose an integrated structure of a motor winding.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: an integrated structure of a motor winding, including a stator core, wherein a groove is opened on the inner wall of the stator core, and the number of grooves is multiple. Positioning grooves are opened on the inner walls of multiple grooves. Locking grooves are opened on both sides of the inner wall of the positioning groove. Tooth poles are installed inside multiple grooves. A sliding groove is opened on the joint surface of the tooth pole and the inner wall of the groove. A lead screw is movably connected to one side inner wall of the sliding groove. A thread is connected to the outer wall of the lead screw located inside the sliding groove with two sliders. Locking pins are fixedly connected to the opposite surfaces of the two sliders. The locking pins are located inside the positioning groove. Windings are sleeved on the outer walls of multiple tooth poles.

[0006] As a further description of the above technical scheme:

[0007] Through holes are opened on the outer walls of multiple tooth poles, and the through holes are communicated with the sliding grooves. The other end of the lead screw is located inside the through hole.

[0008] As a further description of the above technical scheme:

[0009] Limiting strips are fixedly connected to the outer wall of the stator core, and the number of limiting strips is multiple.

[0010] As a further description of the above technical scheme:

[0011] The outer wall of the stator core is sleeved with a motor housing. The inner wall of the motor housing is provided with a plurality of limiting grooves, and the number of the limiting strips is multiple. The multiple limiting strips are respectively located inside the multiple limiting grooves.

[0012] As a further description of the above technical solution:

[0013] The inner part of the motor housing is provided with a plurality of threaded holes, and the inner wall of the stator core is provided with a plurality of communication grooves.

[0014] As a further description of the above technical solution:

[0015] The multiple threaded holes respectively correspond to the multiple communication grooves. Bolts are respectively threadedly connected inside the multiple threaded holes, and the other ends of the bolts are located inside the communication grooves.

[0016] The utility model has the following beneficial effects:

[0017] A plurality of grooves are formed in the inner wall of the stator core, and positioning grooves are formed in the inner walls of the plurality of grooves. The winding is wound around the outside of the tooth pole in advance. In the initial state, the two sliders inside the tooth pole are in a relatively close state. Then, the tooth pole sleeved with the winding is inserted into the groove formed in the inner wall of the stator core. At this time, both sliders are located in the positioning grooves formed in the inner part of the groove. Then, the lead screw is rotated to move the two sliders away from each other until the locking pins connected to the outer walls of the sliders are inserted into the locking grooves formed in the inner walls of the positioning grooves, so that the tooth pole is firmly connected to the stator core. When maintaining or replacing the winding, the lead screw is rotated in the reverse direction to move the two sliders relatively, and the locking pins connected to the sliders are removed from the locking grooves, and the tooth pole can be directly taken off for the replacement and maintenance of the winding. The winding sleeving is simple. The tooth pole and the stator core are installed in a separated manner. The winding sleeving is simple. There is no need to use tools to press the winding into an integral stator core, which is convenient for replacing and maintaining the winding, and the disassembly and assembly efficiency is high.

[0018] A plurality of limiting strips are connected to the outer wall of the stator core. When installing the stator core, the limiting strips are aligned with the limiting grooves formed in the inner wall of the motor housing. After the stator core completely enters the motor housing, the stator core can be fixedly connected to the inner wall of the motor housing through a plurality of bolts, ensuring that the stator core will not vibrate during the operation of the motor.
