Description

Technical Field

[0001] The utility model belongs to the technical field of motor rotors, in particular to a rotor structure of a high-efficiency motor. Background Art

[0002] An electric motor, commonly known as a "motor", is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. A high-efficiency motor refers to a motor with higher efficiency, and its efficiency should meet the relevant energy efficiency level requirements. The components of a motor are a stator, a rotor, an end cover, a shaft and bearings, etc. The rotor is usually composed of an iron core and a rotating shaft.

[0003] At present, rotors on the market generate a lot of heat when working. In order not to affect the use effect of the rotor, the rotor needs to be cooled. However, in the existing technology, most rotor cooling methods rely on heat dissipation holes for heat dissipation, and this heat dissipation method has poor heat dissipation effect, thereby reducing the service life of the rotor. Utility Model Content

[0004] The purpose of the present utility model is to provide a rotor structure of a high-efficiency motor to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a rotor structure of a high-efficiency motor, comprising a rotor body and a heat dissipation assembly; wherein, the rotor body comprises a rotating shaft body and an iron core body; the iron core body is sleeved on the rotating shaft body; the heat dissipation assembly is arranged on the iron core body; wherein, the heat dissipation assembly comprises a heat dissipation groove and a slow-flow groove; a plurality of heat dissipation grooves are evenly arranged on the iron core body; a plurality of slow-flow grooves are symmetrically arranged on both sides of the inner wall of the heat dissipation groove in a linear array.

[0006] As a preferred embodiment, the slow flow grooves on both sides of the inner wall of the heat dissipation groove are staggered.

[0007] As a preferred embodiment, the slow flow trough includes a drainage portion and a slow flow portion, the drainage portion is in an inclined structure, and the opening direction formed by the two drainage portions is arranged toward the slow flow portion.

[0010] As a preferred embodiment, the expansion groove is an arc-shaped isosceles trapezoidal structure, and the size of the expansion groove close to the drainage portion is smaller than the size of the expansion groove away from the drainage portion.

[0011] As a preferred embodiment, the inclination direction of the expansion groove is the same as the rotation direction of the rotor body.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are:

[0013] The rotor structure of the high-efficiency motor is provided with a heat dissipation component. When the rotor body rotates, the gas in the high-efficiency motor will enter the heat dissipation groove, causing the gas to flow in the heat dissipation groove. Moreover, the gas flowing in the heat dissipation groove can take away the heat generated by the rotor body during the rotation process, thereby achieving heat dissipation of the rotor body. When the gas flows in the heat dissipation groove, the gas will pass through the slow flow groove, so that the gas flows in the heat dissipation groove for a longer time, thereby improving the heat dissipation effect of the rotor body.

[0014] The rotor structure of the high-efficiency motor is provided with an expansion groove, which is arranged into an arc-shaped isosceles trapezoidal structure, and the size of the expansion groove close to the drainage portion is smaller than the size of the expansion groove away from the drainage portion. When the rotor body rotates, the gas in the motor can more easily and in large quantities pass through the inclined surface of the expansion groove into the heat dissipation groove, so as to increase the flow of gas and further improve the heat dissipation effect, thereby improving the practicality of the utility model.

[0029] The utility model provides a heat dissipation component 2. When the rotor body 1 rotates, the gas in the high-efficiency motor will enter the heat dissipation groove 201, so that the gas flows in the heat dissipation groove 201. Moreover, the gas flowing in the heat dissipation groove 201 can take away the heat generated by the rotor body 1 during the rotation process, thereby achieving heat dissipation of the rotor body 1. When the gas flows in the heat dissipation groove 201, the gas will pass through the slow flow groove 202, so that the gas flows in the heat dissipation groove 201 for a longer time, thereby improving the heat dissipation effect of the rotor body 1.

[0030] As a preferred embodiment, the slow flow groove 202 includes a guide portion 2021 and a slow flow portion 2022. The guide portion 2021 has an inclined structure, and the opening formed by the two guide portions 2021 is arranged in the direction of the slow flow portion 2022. The slow flow portion 2022 has an arc-shaped structure. When the gas flows in the heat dissipation groove 201, it will pass through the guide portion 2021. After being guided by the guide portion 2021, it will gather in the slow flow portion 2022. After flowing back through the slow flow portion 2022, the gas in the slow flow portions 2022 on both sides of the heat dissipation groove 201 will converge with each other, allowing the gas to flow again from the position it has flowed through, so that the gas can repeatedly remove the heat generated by the rotor body 1 during the rotation process.

[0031] As a preferred embodiment, it also includes a flow expansion groove 3; the flow expansion groove 3 is opened at the entrance of the heat dissipation groove 201; wherein, the flow expansion groove 3 is an arc-shaped isosceles trapezoidal structure, and the size of the flow expansion groove 3 close to the drainage portion 2021 is smaller than the size of the flow expansion groove 3 away from the drainage portion 2021; wherein, the inclination direction of the flow expansion groove 3 is the same as the rotation direction of the rotor body 1.

[0032] The utility model sets the expansion groove 3, and sets the expansion groove 3 into an arc-shaped isosceles trapezoidal structure, and the size of the expansion groove 3 close to the drainage portion 2021 is smaller than the size of the expansion groove 3 away from the drainage portion 2021. When the rotor body 1 rotates, the gas in the motor can more easily and in large quantities pass through the inclined surface of the expansion groove 3 into the heat dissipation groove 201, so as to increase the flow of gas and further improve the heat dissipation effect, thereby improving the practicality of the utility model.

[0033] The rotor body 1 is a conventional instrument. Its working principle, size and model are irrelevant to the problem solved by this application, so no further description will be given. The control method of the present invention is controlled by a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
