Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a stable output hollow cup motor. Background Technology

[0002] With the rapid development of technology, various industries have increasingly stringent requirements for motor performance. In fields such as aerospace, medical equipment, and high-end electronic equipment manufacturing, motors not only need to have efficient power output, but also need to ensure the stability of the output to ensure the precise operation of the entire system. Coreless motors have been widely used in these fields due to their advantages such as low inertia, high response speed, and good speed regulation performance.

[0003] In existing technologies, traditional coreless motors have significant shortcomings in meeting the requirements for high precision and high stability. In terms of connection methods, the conventional interface design makes the connection process between the motor and the power supply or control equipment extremely cumbersome. For example, in automated production lines, if the motor needs to be replaced or debugged, the staff needs to spend a lot of time plugging and unplugging the interface, and the interface may be damaged due to improper operation. This not only delays the production schedule but also increases the equipment maintenance cost. In addition, the heat dissipation effect of traditional coreless motors is not ideal. When running under high load for a long time, the heat generated inside the motor cannot be dissipated in time, which affects the output stability of the motor and shortens its service life. Utility Model Content

[0004] The purpose of this invention is to solve the problems of conventional interface design in the prior art, which makes the connection process between the motor and the power supply or control equipment extremely cumbersome, and the unsatisfactory heat dissipation effect of traditional coreless motors, and to propose a stable output coreless motor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a stable output hollow cup motor, comprising a housing, a magnet fixedly installed on the inner side of the housing, a brush holder fixedly installed on the inner side of the housing, a rotor disposed inside the housing, an output shaft fixedly connected to one end of the rotor, a front cover disposed on one side of the housing, a rear cover disposed on the other side of the housing, a bearing body fixedly installed inside the front cover, a bearing cap bolted to the side of the front cover, a through hole through the side of the rear cover, a power socket disposed inside the housing, a plug disposed inside the power socket, and a quick plug-in / plug-out mechanism disposed inside the power socket;

[0006] The quick plug-in / plug-out mechanism includes a powerful magnet A, which is located inside the power socket. A powerful magnet B is provided on the side of the plug. A tension spring is fixedly installed inside the plug. A limit block is slidably connected inside the plug. A limit hole is opened on the side of the power socket.

[0007] Preferably, the rotor is located between the magnets, and the output shaft is rotatably connected to the bearing body.

[0008] Preferably, the strong magnet A and the strong magnet B are attracted to each other, and there are two sets of strong magnet A and strong magnet B.

[0009] Preferably, one end of the tension spring is fixedly connected to the side of the limiting block.

[0010] Preferably, the limiting block and the limiting hole are slidably connected.

[0011] Preferably, the other end of the rotor is fixedly connected to a connecting shaft, the surface of the connecting shaft is provided with fan blades, and the side of the rear cover is provided with heat dissipation fins.

[0012] Preferably, the number of heat dissipation fins is three sets, and they are distributed in a circular pattern on the side of the back cover.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, through the design of a quick plug-in / plug-out mechanism, when the plug is inserted into the power socket, strong magnet A and strong magnet B attract each other for easy and quick positioning. After insertion, the limiting block pops out under the action of the tension spring and slides into the limiting hole to ensure a stable connection. When disassembling, pressing the limiting block overcomes the tension spring force to disengage it from the limiting hole, allowing the plug to be quickly pulled out. In scenarios where frequent motor replacement or equipment debugging is required, this greatly improves the convenience of connecting the motor to the external power supply, reduces connection and disassembly time, and avoids damage to the interface due to improper operation. Furthermore, the output shaft is fixedly connected to one end of the rotor, and the output shaft is rotatably connected to the bearing body inside the front cover, ensuring the stability and smoothness of the motor's power output.

[0015] 2. In this utility model, a connecting shaft is fixedly connected to the other end of the rotor, and fan blades are provided on the surface of the connecting shaft. Multiple sets of circumferentially distributed heat dissipation fins are provided on the side of the rear cover. When the motor is running, the rotor drives the fan blades to rotate, which accelerates the air flow. With the help of the heat dissipation fins, the heat generated inside the motor can be effectively dissipated, the motor temperature can be reduced, the motor performance can be avoided due to excessive temperature, the service life of the motor can be extended, and thus stable output can be achieved.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figures 1-5As shown, this utility model provides a technical solution: a stable output hollow cup motor, including a housing 1, a magnet 2 fixedly installed on the inner side of the housing 1, a brush holder 3 fixedly installed on the inner side of the housing 1, a rotor 4 disposed inside the housing 1, an output shaft 5 fixedly connected to one end of the rotor 4, a front cover 6 disposed on one side of the housing 1, a rear cover 7 disposed on the other side of the housing 1, a bearing body 8 fixedly installed inside the front cover 6, a bearing cover 9 bolted to the side of the front cover 6, a through hole 10 through the side of the rear cover 7, a power socket 11 disposed inside the housing 1, a plug 12 disposed inside the power socket 11, and a quick-plug mechanism disposed inside the power socket 11, the quick-plug mechanism including... A strong magnet A131 is located inside the power socket 11. A strong magnet B132 is located on the side of the plug 12. A tension spring 133 is fixedly installed inside the plug 12. A limit block 134 is slidably connected inside the plug 12. A limit hole 135 is opened on the side of the power socket 11. The rotor 4 is located between the magnets 2. The output shaft 5 is rotatably connected to the bearing body 8. The strong magnets A131 and B132 attract each other. There are two sets of strong magnets A131 and B132. One end of the tension spring 133 is fixedly connected to the side of the limit block 134. The limit block 134 is slidably connected to the limit hole 135.

[0025] In this embodiment, through the design of the quick plug-in / plug-out mechanism, when the plug 12 is inserted into the power socket 11, the strong magnets A131 and B132 attract each other, facilitating quick positioning. After insertion, the limiting block 134 pops out and slides into the limiting hole 135 under the action of the tension spring 133, ensuring a stable connection. When disassembling, pressing the limiting block 134 overcomes the elastic force of the tension spring 133 to disengage it from the limiting hole 135, allowing the plug 12 to be quickly pulled out. In scenarios where frequent motor replacement or equipment debugging is required, this greatly improves the convenience of connecting the motor to the external power supply, reduces connection and disassembly time, and avoids damage to the interface due to improper operation. Furthermore, the output shaft 5 is fixedly connected to one end of the rotor 4, and the output shaft 5 is rotatably connected to the bearing body 8 inside the front cover 6, ensuring the stability and smoothness of the motor's power output.

[0026] Example 2: As Figures 1-5 As shown, the other end of the rotor 4 is fixedly connected to a connecting shaft 18. The surface of the connecting shaft 18 is provided with fan blades 19. The side of the rear cover 7 is provided with heat dissipation fins 20. There are three sets of heat dissipation fins 20, which are distributed in a circular pattern on the side of the rear cover 7.

[0027] In this embodiment, by fixing a connecting shaft 18 to the other end of the rotor 4 and setting a fan blade 19 on the surface of the connecting shaft 18, and providing multiple sets of circumferentially distributed heat dissipation fins on the side of the rear cover 7, when the motor is running, the rotor 4 drives the fan blade 19 to rotate, accelerating the airflow. With the help of the heat dissipation fins, the heat generated inside the motor can be effectively dissipated, reducing the motor temperature, avoiding the impact of excessive temperature on motor performance, extending the service life of the motor, and thus achieving stable output.

[0028] The working principle of this embodiment is as follows: When it is necessary to connect the power supply to the motor, the quick-plug mechanism is operated. The plug 12 is aligned with the power socket 11. Since the strong magnet A131 inside the power socket 11 and the strong magnet B132 on the side of the plug 12 attract each other (there are two sets of both), the plug 12 can be easily and quickly positioned. During insertion, the limiting block 134, which is slidably connected inside the plug 12, is compressed under the action of the tension spring 133. When the plug 12 is fully inserted, the limiting block 134 aligns with the limiting hole 135 on the side of the power socket 11. The tension spring 133 pops the limiting block 134 out, causing it to slide into the limiting hole 135, thereby ensuring that the plug 12 is properly inserted. The power socket 11 is securely connected. To remove the plug 12, simply press the limiting block 134 to overcome the tension spring 133, causing the limiting block 134 to disengage from the limiting hole 135, allowing the plug 12 to be quickly pulled out. During motor operation, current is input to the motor through the connection between the power socket 11 and the plug 12, causing the rotor 4 to rotate under the magnetic field generated by the magnet 2. This, in turn, drives the output shaft 5 to rotate and output power. Simultaneously, the connecting shaft 18, which is fixedly connected to the other end of the rotor 4, also rotates, and the fan blades 19 on the surface of the connecting shaft 18 rotate accordingly, accelerating airflow. The three sets of heat dissipation fins distributed circumferentially on the side of the rear cover 7, in conjunction with the airflow driven by the fan blades 19, quickly dissipate the heat generated during motor operation, maintaining the motor at a suitable temperature, ensuring stable motor performance, and achieving stable output.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
