Description

Technical Field

[0001] The utility model belongs to the field of motors and relates to a stator and rotor, in particular to a stator and rotor which is convenient for heat dissipation. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy. It uses an energized coil to generate a rotating magnetic field and thereby drives the rotor to output torque. The stator and rotor are both important components of the motor. The two components cooperate with each other through the action of the energized coil to convert electromagnetic energy into mechanical energy.

[0003] The stator and rotor generate heat during rotation. In order to dissipate the heat generated by the stator and rotor, an impeller is usually installed inside the stator and rotor as a heat dissipation component. However, the heat dissipation effect of the impeller is not ideal, and it is difficult to dissipate the heat generated in the stator slot. The heat inside the rotor cannot be fully dissipated, causing the motor coil to age due to high temperature, reducing the motor's working energy efficiency.

[0004] For example, patent number CN202123073048.X is a quick-assembly high-efficiency heat dissipation motor stator and rotor. In order to solve the problem that the stator and rotor are installed with an impeller through a threaded connection but it is inconvenient to disassemble and the threaded structure is easily worn, an impeller positioning plate is installed on the rotating shaft, and a buckle 1 is provided on the impeller, and a buckle 2 is provided on the impeller positioning plate. Buckle 1 and buckle 2 are engaged with each other to complete the installation of the impeller.

[0005] The above patent solves the problem that the impeller is difficult to disassemble and assemble due to threaded connection and is prone to wear, but the heat dissipation of the impeller is difficult to completely dissipate the heat inside the stator and rotor, and the heat dissipation efficiency is not high. Utility Model Content

[0006] The purpose of the utility model is to provide a stator and rotor with better heat dissipation effect in view of the above problems existing in the prior art.

[0008] In the above-mentioned stator and rotor for facilitating heat dissipation, heat dissipation teeth are arranged in the winding grooves.

[0009] In the above-mentioned stator and rotor for facilitating heat dissipation, a groove is provided on the fixing frame, and the cooling pipe is placed on the groove.

[0010] In the above-mentioned stator and rotor for facilitating heat dissipation, a sealing plug is fixedly mounted on the cooling pipe, and a plurality of sealing rings are mounted on the sealing plug.

[0011] In the above-mentioned stator and rotor for facilitating heat dissipation, a plurality of sealing grooves are provided on the inner wall of the opening of the cooling pipe, and the sealing grooves correspond to the sealing rings.

[0012] In the above-mentioned stator and rotor for facilitating heat dissipation, a mounting portion is provided on the cooling pipe, and mounting bolts are installed at the mounting portion.

Implementation

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] like Figures 1 to 6As shown, the utility model can be implemented through the following embodiments: a stator and rotor that are easy to dissipate heat, including a stator core 1, a rotor core 2 and a cooling assembly 4, the stator core 1 is provided with a winding groove 11, the stator core 1 and the rotor core 2 are provided with fixing holes 3, the cooling assembly 4 is divided into a fixing frame 41 and a cooling pipe 42, the cooling pipe 42 is installed on the fixing frame 41, the fixing frame 41 is installed on the stator core 1 and the rotor core 2 by fixing bolts 5, the fixing bolts 5 are installed in the fixing holes 3, the stator core 1 and the rotor core 2 are provided with heat dissipation grooves 6, the cooling pipe 42 is installed in the heat dissipation grooves 6, and the cooling pipe 42 is filled with coolant 421.

[0023] A cooling assembly 4 is installed on the stator core 1 and the rotor core 2. A cooling pipe 42 installed on the cooling assembly 4 extends into the heat dissipation holes opened in the stator core 1 and the rotor core 2 to increase the cooling capacity of the coolant 421 on the stator core 1 and the rotor core 2. A fixing frame 41 of the cooling assembly 4 is used to install and fix the stator core 1, which reduces the processing of the stator core 1 and the rotor core 2 and facilitates the disassembly, assembly and replacement of the cooling assembly 4.

[0024] like Figure 2 and Figure 5 As shown, a heat dissipation tooth 111 is provided in the winding slot 11. The heat dissipation tooth 111 can absorb the heat of the air in the winding slot 11, guide the heat into the stator core 1, and cool it through the cooling pipe 42, thereby improving the heat dissipation efficiency.

[0025] like Figure 1 As shown, a groove 411 is provided on the fixing frame 41, and the cooling pipe 42 is placed on the groove 411. The groove 411 facilitates the positioning and placement of the cooling pipe 42, and prevents the cooling pipe 42 from being displaced when the stator and rotor move, causing the cooling pipe 42 to rub against the stator core 1 and the rotor core 2, causing the coolant 421 to leak, or the iron filings generated by the friction to affect the normal operation of the stator and rotor.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, a sealing plug 7 is fixedly mounted on the cooling pipe 42, and a plurality of sealing rings 71 are mounted on the sealing plug 7. The installation of the sealing plug 7 can ensure that the cooling pipe 42 does not leak the coolant 421 when the stator and rotor are running, and the sealing ring 71 enhances the sealing performance of the sealing plug 7.

[0027] like Figure 4 As shown, the inner wall of the opening of the cooling pipe 42 is provided with a plurality of sealing grooves 422, and the sealing grooves 422 correspond to the sealing ring 71. The mutual cooperation between the sealing grooves 422 and the sealing ring 71 improves the sealing performance between the sealing ring 71 and the sealing grooves 422.

[0028] like Figure 1 and Figure 2As shown, the cooling pipe 42 is provided with a mounting portion 423, and a mounting bolt 8 is installed at the mounting portion 423. The mounting bolt 8 is threadedly connected to fix the mounting portion 423 and the fixing frame 41, so that the sealing plug 7 and the cooling pipe 42 are fixed on the mounting frame. At the same time, the cooling pipe 42 can be replaced without disassembling the fixing frame 41, thereby improving the efficiency of replacing the coolant 421.

[0029] The working principle of the utility model is to pour the coolant 421 into the cooling tube 42, and insert the sealing plug 7 into the cooling tube 42, then install the fixing frame 41 on the stator core 1 and the rotor core 2 through the fixing bolts 5, and then connect and fix the mounting portion 423 of the cooling tube 42 and the fixing frame 41 through the mounting bolts 8. If the cooling tube 42 needs to be replaced, the above steps can be reversed.

[0030] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0031] Although various terms are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
