Description

Technical Field

[0001] This utility model relates to the field of stator core technology in motors, and in particular to a stator core for positioning, blocking and protection of wire groups. Background Technology

[0002] The stator core and rotor core together constitute the main magnetic circuit of the motor, and at the same time provide the installation and support structure for the stator winding. When the motor is running, the current flowing through the stator winding generates an alternating magnetic field. Through its excellent magnetic permeability, it guides the magnetic field to form a closed loop, reducing magnetic energy loss. In addition, its performance directly determines the motor's iron loss, efficiency, torque ripple and noise level. It is the core guarantee for the stable operation of motors in many devices such as new energy vehicles, electric bicycles, and compressors.

[0003] Different types and specifications of motors require corresponding stator cores. In modern industry, where the requirements for motor speed and power are becoming increasingly stringent, existing stator cores are increasingly unable to meet the needs. Therefore, a new type of lock core is needed, which adds a protective layer to the groove of the stator core winding to prevent the coil from being damaged during the winding process. In addition, the stator laminations are positioned by their own structure to improve assembly efficiency during assembly. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a stator core for wire positioning and blocking protection, so as to avoid damage to the wires during the winding process, and to improve the assembly efficiency of the stator laminations through the positioning of the stator core itself.

[0005] This utility model also provides a stator core with the above-mentioned wire group positioning and blocking protection, including a stator body, the stator body being composed of several stator laminations stacked and fixed, several isolation plates being fixedly connected to the inner side of the stator laminations, the isolation plates forming a winding slot, a protective coating being fixedly connected to the inner side of the winding slot, four circular pins protruding from one side of the stator laminations, and four circular grooves recessed from the other side of the stator laminations.

[0006] According to the present invention, a stator core for positioning and blocking protection of a winding assembly is provided, wherein four sets of through fixing holes are provided at the four corners of the stator lamination, and the fixing holes are located on the outside of the winding slots.

[0007] According to the present invention, a stator core for positioning and blocking protection is provided, wherein four sets of through-holes for injecting glue are provided on the side of the stator body, and the glue injection holes are located outside the protective coating.

[0008] According to the present invention, a stator core for positioning and blocking protection of a wire group is provided, wherein a toothed groove is fixedly connected to the inner side of the isolation plate, and the toothed groove is located on the inner side of the stator plate.

[0009] Beneficial effects: 1. The stator body is composed of several stator laminations stacked and fixed together. Several isolation plates are fixedly connected to the inside of the stator laminations. The isolation plates form a winding slot. A protective coating is fixedly connected to the inside of the winding slot.

[0013] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0014] Reference Figure 1-6This utility model provides a stator core for positioning, blocking and protecting a wire group. It includes a stator body 1, which is composed of several stator plates 2 stacked and fixed. Several isolation plates 6 are fixedly connected to the inner side of the stator plates 2. The isolation plates 6 form a winding groove 3. A protective coating 9 is fixedly connected to the inner side of the winding groove 3. Four circular pins 8 are protruding on one side of the stator plate 2, and four circular grooves 7 are recessed on the other side of the stator plate 2.

[0015] Specifically, when stacking and fixing stator laminations 2, alignment is required. In traditional production, this operation requires the use of alignment tools. However, after the circular pin 8 and the circular groove 7 are engaged and fixed, it can not only strengthen the connection between stator laminations 2, but also accurately position and align the two stator laminations 2 without the aid of tools. The protective coating 9 is made of high-temperature resistant rubber, which can prevent the coil from contacting the side opening edge of the stator body 1 during coil winding, thereby reducing the possibility of coil damage due to friction. At the same time, it can prevent the two from contacting each other and causing a short circuit, which could burn out the coil assembly.

[0016] The stator lamination 2 has four sets of through fixing holes 4 at its four corners, which are located outside the winding slot 3.

[0017] Specifically, the function of the fixing hole 4 is to assist in fixing the stator body 1 to the motor housing.

[0018] The stator body 1 has four sets of through-holes 5 for injecting glue, which are located outside the protective coating 9.

[0019] Specifically, the injection hole 5 is used to inject insulating adhesive. The activated coating enables the laminations to automatically bond during stacking without additional welding or riveting, reducing magnetic circuit interference and improving the overall integrity of the force stator laminations 2 after stacking.

[0020] The inner side of the isolation plate 6 is fixedly connected with a toothed groove 10, which is located inside the stator plate 2.

[0021] Specifically, the function of the toothed groove 10 is to ensure uniform magnetic field distribution, reduce torque pulsation, and reduce motor noise during vehicle operation.

[0022] Working principle: When assembling the stator core, first align the two stator plates 2, and then align and fix the circular pins 8 and circular grooves 7 on the side of the stator plates 2. Similarly, align and fix the stator plates 2 in sequence according to the setting requirements until they form a complete stator body 1. Insulating adhesive is injected into the injection hole 5, which makes the stator plates 2 adhere more tightly and enhances the integrity of the stator body 1. Finally, a protective coating 9 is evenly applied to the winding slots 3 between the isolation plates 6, and the side edges of the stator body 1 become smooth.

[0023] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
