[0002] The stator is an important component of motors such as generators and starters. It is a crucial part of the electric motor. The stator consists of three parts: the stator core, the stator windings, and the frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by magnetic lines of force within this rotating magnetic field, thereby generating (output) current.
[0003] With the increasing demand for high-performance motors in fields such as new energy and industrial automation, the heat generation and mechanical stability of motors directly affect their reliability and lifespan. However, in traditional motor stators, the busbars and copper wires are prone to unsoldering under vibration, leading to short circuit faults. Utility Model Content

However, in traditional motor stators, the busbar and copper wire are prone to unsoldering under vibration, leading to short circuit faults.
[0005] To achieve the above objectives, this utility model provides a motor stator assembly with a plastic-coated structure, including a stator core and a connecting device.

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0019] The embodiment of this application is as follows:
[0020] Please see Figure 1-5 , Figure 1 This is a schematic diagram of the overall structure of a motor stator assembly with a plastic-coated structure according to this utility model. Figure 2 This is a schematic diagram of the conductive component of this utility model. Figure 3 This is a schematic diagram showing the connection between the stator core and the insulating housing of this utility model.

[0021] This utility model provides a motor stator assembly with a plastic-coated structure: it includes a stator core 101 and a connecting device, which includes an insulating housing 102, a wire group 103, a conductive component, and a plastic-coated resin 105. The aforementioned solution solves the problem that with the increasing demand for high-performance motors in fields such as new energy and industrial automation, the heating and mechanical stability of the motor directly affect the reliability and lifespan of the motor. However, in traditional motor stators, the busbar and copper wire are prone to unsoldering under vibration, leading to short circuit faults.
[0022] In this embodiment, the stator core 101, the insulating housing 102, the wire group 103, and the conductive component are integrally coated with the plastic coating resin 105, thereby preventing the conductive component and the wire group 103 from detaching under vibration.
[0023] The insulating housing 102 is sleeved on the stator core 101. The wire group is wound around the outside of the insulating housing 102. The conductive component is installed on the stator core 101. The plastic coating resin 105 is disposed on the outside of the stator core 101. There are multiple sets of stator cores 101, which are arranged in a circular structure. Each set of stator cores 101 has two sets of insulating housings 102, which are disposed on the upper and lower sides of the stator core 101. The insulating housing 102 is made of insulating material. The wire group 103 is made of copper material and is composed of multiple copper wires. The ends of the copper wires are vertically arranged. The conductive component is used to establish a low-impedance conductive channel for the wire group 103, so that the wire... Group 103 is connected to an external power source. The plastic coating resin 105 wraps around the outside of the stator assembly. At the same time, the plastic coating resin 105 can evenly conduct the heat generated by the wire group 103, enhancing the heat dissipation effect of the overall stator structure. During installation, the insulating clip 102 is sleeved on the stator core 101, and the stator core 101 is formed into a circular structure by winding the wire group 103. The conductive component is installed from top to bottom on the top of the stator core 101. Finally, the stator core 101, the insulating clip 102, the wire group 103, and the conductive component are integrally plastic coated with the plastic coating resin 105, thereby preventing the conductive component and the wire group 103 from detaching under vibration.
[0024] Secondly, the three-phase terminal 106 and the neutral point terminal 107 are both mounted on the stator core 101 through the support member. The three-phase terminal 106 and the neutral point terminal 107 are respectively fixedly connected to the wire group 103. The three-phase terminal 106 consists of three phases: U phase, V phase and W phase. The support member facilitates the mounting of the three-phase terminal 106 and the neutral point terminal 107 on the stator core 101. The three-phase terminal 106 and the neutral point terminal 107 facilitate the connection of the wire group 103 to an external power source.
[0025] Furthermore, the support ring 108 is fixedly connected to the three-phase terminal 106 and the neutral point terminal 107; the insert 109 is fixedly connected to the support ring 108, and the insert 109 is inserted into the stator core 101. The support ring 108 has a circular structure, and there are multiple sets of inserts 109 arranged in a ring at the bottom of the support ring 108. The insert 109 has an inverted L-shaped structure. Through the cooperation of the support ring 108 and the insert 109, it is convenient to insert the support ring 108 into the stator core 101 after it is formed into a circle, thereby facilitating the installation of the three-phase terminal 106 and the neutral point terminal 107 on the stator core 101.
[0026] Furthermore, the first claw 110 is fixedly installed on the three-phase terminal 106; the second claw 111 is fixedly installed on the neutral point terminal 107. Each phase of the three-phase terminal 106 is provided with a first claw 110, and the number of second claws 111 is the same as the number of neutral point terminals 107. Both the first claw 110 and the second claw 111 are V-shaped structures. The arrangement of the first claw 110 and the second claw 111 facilitates the welding of the ends of the wire group 103 to the first claw 110 and the second claw 111 respectively, making the connection between the ends of the wire group 103 and the three-phase terminal 106 and the neutral point terminal 107 more stable.
[0027] Finally, the slots 112 are spaced apart on the outside of the insulating housing 102. There are multiple sets of slots 112, which are linearly distributed on the outside of the insulating housing 102. The slots 112 facilitate the winding of the wire group 103 into the slots 112 when the wire group 103 is wound around the insulating housing 102, thereby limiting the winding of the wire group 103 and making the winding of the wire group 103 more stable.
[0028] In this embodiment, during use, two sets of insulating clips 102 are respectively fitted onto the stator core 101 from the upper and lower ends. Then, the wire group 103 is wound around the slots 112 on the insulating clips 102, so that the stator core 101 forms a circular structure. Then, the support ring 108 and the insert 109 are inserted into the upper end of the stator core 101, so that the end of the wire group 103 is inserted into the first claw 110 and the second claw 111. The first claw 110 and the second claw 111 are then welded to the end of the wire group 103. Finally, the stator core 101, the insulating clips 102, the wire group 103 and the conductive component are integrally coated with the plastic coating resin 105, thereby preventing the conductive component and the wire group 103 from detaching under vibration.
[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
