Description

Technical Field

[0001] The utility model mainly relates to the technical field of motors, and in particular to a heat dissipation structure of a brake motor. Background Art

[0002] The brake motor is also known as the electromagnetic power-off brake motor and the brake asynchronous motor. Its working principle is that there is an electromagnetic brake at the tail of the motor. When the motor is powered on, it is also powered on and attracted. At this time, it does not brake the motor. When the motor is powered off, it is also powered off. The brake brakes the motor under the action of the spring.

[0003] In addition to generating heat when the existing brake motor itself is running, the electromagnetic brake at the tail of the motor consumes electrical energy to generate braking torque when working, which will cause the electromagnetic brake to heat up. If the motor temperature is too high, the motor efficiency will decrease or even be damaged, and the brake device will not work properly. Utility Model Content

Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive. Example

The heat dissipation device 3 includes a positive blade fan 301 and a negative blade fan 302. The positive blade fan 301 is connected to the output shaft 102, and the negative blade fan 302 is set at the tail of the brake device 2.

[0023] It should be noted that mounting blocks 104 are provided on the left and right sides of the motor body 1, cooling fins 103 are provided on the motor body 1, a front cover 4 is connected to the output shaft 102, the positive blade fan 301 is located inside the front cover 4, a heat dissipation groove 201 is provided on the surface of the brake device 2, the brake device 2 is connected to the rear cover 5, and the reverse blade fan 302 is located inside the rear cover 5.

[0024] It should be noted that the heat dissipation fins 103 are evenly distributed on the outer surface of the motor body 1, further increasing the heat dissipation area and facilitating heat dissipation. The heat dissipation slots 201 are evenly distributed on the outer surface of the brake device 2, improving the heat dissipation capacity of the brake device 2.

[0025] Please refer to the attached Figure 3 As shown, a bearing 401 is provided at the center of the front cover 4 , an air inlet 402 is opened on the front cover 4 , a first dustproof net 403 is provided in the air inlet 402 , and the positive blade fan 301 draws air into the motor through the air inlet 402 .

[0026] It should be noted that the output shaft 102 is rotatably connected to the front cover 4 via the bearing 401 and can pass through the front cover 4 without affecting the rotation. The first dustproof net 403 can block external dust and impurities to ensure the normal operation of the positive blade fan 301.

[0027] Please refer to the attached Figure 4 As shown, a heat sink 501 is provided on the outer surface of the back cover 5 , an air outlet 502 is opened on the back cover 5 , a second dustproof net 503 is provided inside the air outlet 502 , and the reverse blade fan 302 discharges hot air outward from the air outlet 502 .

[0028] It should be noted that the heat sink 501 is evenly distributed on the outer surface of the rear cover 5 in a circular shape, thereby improving the heat dissipation capacity of the brake device 2. The second dustproof net 503 can block external dust and impurities to ensure the normal operation of the reverse blade fan 302.

[0029] It should be noted that the positive blade fan 301 provided on the output shaft 102 can draw air into the motor through the air inlet 402, while the negative blade fan 302 provided at the rear of the brake device 2 can exhaust hot air outward through the air outlet 502, thus forming a good air convection. This air convection can quickly remove the heat generated by the motor body 1 and the brake device 2 during operation.

[0030] The specific operation mode of the utility model is as follows:

[0031] When the brake motor is operating, the output shaft 102 drives the straight-blade fan 301 to draw cool air in through the air inlet 402. The first dust screen 403 of the air inlet 402 filters dust. The cool air flows through the motor body 1, where its heat dissipation fins 103 transfer heat to the air. Heat generated by the brake mechanism 2 is dissipated through the surface heat dissipation grooves 201. The reverse-blade fan 302 inside the rear cover 5 at the rear of the brake mechanism 2 exhausts the hot air through the air outlet 502. The second dust screen 503 of the air outlet 502 prevents dust from entering. The heat dissipation fins 501 on the surface of the rear cover 5 further dissipate the heat from the brake mechanism 2. The straight-blade fan 301 and the reverse-blade fan 302 work together to create air convection, removing heat from the motor body 1 and the brake mechanism 2. The mounting blocks 104 on both sides of the motor body are used to mount the motor and ensure its stable operation. The heat dissipation fins 103, heat dissipation grooves 201, heat sink 501, and fans work together to ensure motor performance and life.

As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
