Description

Technical Field

[0001] This utility model relates to the technical field of motor structure, specifically a cooled servo motor. Background Technology

[0002] Electric motors are a common power source with a wide range of applications, typically including various types such as stepper motors and servo motors. Servo motors, in particular, drive controlled objects by converting voltage signals into torque and speed, achieving accurate control of speed and position. They are usually an important component of servo systems, providing power output. Since servo motors need to meet the requirements of high-speed operation, cooling and heat dissipation of servo motors are very important.

[0003] Especially for high-power servo motors, heat dissipation during operation is directly related to their service life. If the motor operating temperature is too high, it may malfunction and shorten its service life. Therefore, those skilled in the art have proposed a cooled servo motor to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to provide a cooled servo motor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] As a further embodiment of this utility model: the blowing assembly includes an annular tube disposed on the inner wall of the outer shell, and a plurality of air outlet pipes disposed on the annular tube; a wind pump is installed on the cooling box; a condenser pipe is installed inside the cooling box; and the outlet end of the wind pump and the inlet end of the annular tube are both connected to the inner cavity of the cooling box.

[0008] As a further embodiment of this utility model: the location and quantity of the cooling components correspond to the air outlet pipe. The cooling components include an air inlet duct disposed on the outer wall of the inner sleeve and a connecting bracket disposed on the inner wall of the inner sleeve. The inner circumferences of the air inlet duct and the connecting bracket are respectively provided with a first heat-conducting plate and a second heat-conducting plate. The middle part of the first heat-conducting plate is connected to the middle part of the second heat-conducting plate through a heat-conducting rod. The two ends of the first heat-conducting plate extend to the outside of the air inlet duct, and the two ends of the second heat-conducting plate extend to the outside of the connecting bracket.

[0009] As a further improvement of this utility model, the inner diameter of the air inlet duct gradually decreases from the direction near the outer shell to the direction near the inner sleeve.

[0010] As a further embodiment of this utility model: a support block is connected to the end of the connecting bracket away from the inner sleeve, and the end of the support block away from the connecting bracket abuts against the outer wall of the motor body, and the support block is U-shaped.

[0011] This utility model has the following advantages: The motor structure provides double protection for the motor body through the outer shell and the inner sleeve. Even if the outer shell is dented or damaged by external impact, it will not directly damage the motor body. The inner wall of the outer shell is equipped with a blower assembly, the inner sleeve is equipped with a cooling assembly, and the outer wall of the outer shell is equipped with a cooling box. The blower assembly, cooling box and cooling assembly are balanced, which can achieve sufficient heat dissipation inside the outer shell, ensure a good operating environment for the motor body and have greater practicality.

[0020] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0021] Example 1: Please refer to Figures 1 to 4 A cooled servo motor includes a housing 1, a cooling box 7 on the top of the housing 1, a control box 9 mounted on the cooling box 7, a blower assembly on the inner wall of the housing 1, a fan pump 8 inside the cooling box 7, the blower assembly being connected to the fan pump 8, end caps 11 and sealing plates 10 at both ends of the housing 1, an inner sleeve 3 in the middle of the inner cavity of the housing 1, a motor body 2 inside the inner sleeve 3, and several cooling components 4 evenly distributed around the circumference of the inner sleeve 3, an end cap 11 at the front end of the housing 1 with a filter screen 12, and a removable sealing plate 10 at the rear end of the housing 1. The cooling box 7 is positioned near the rear end of the housing 1 so that the blown-out cold air can pass through the entire inner cavity of the housing 1.

[0022] Please see Figures 1 to 4The blowing assembly includes an annular pipe 5 disposed on the inner wall of the outer casing 1, and a plurality of air outlet pipes 6 disposed on the annular pipe 5. A wind pump 8 is installed on the cooling box 7, and a condenser pipe is installed inside the cooling box 7. The outlet end of the wind pump 8 and the inlet end of the annular pipe 5 are both connected to the inner cavity of the cooling box 7. In this embodiment, the position and number of the cooling assembly 4 correspond to the air outlet pipes 6. The cooling assembly 4 includes an air inlet pipe 14 disposed on the outer wall of the inner sleeve 3 and a plurality of air outlet pipes 6 disposed on the annular pipe 5. A connecting bracket 18 is placed on the inner wall of the inner sleeve 3. The inner circumference of the air inlet duct 14 and the connecting bracket 18 are respectively provided with a first heat-conducting plate 15 and a second heat-conducting plate 17. The middle part of the first heat-conducting plate 15 is connected to the middle part of the second heat-conducting plate 17 through a heat-conducting rod 16. The two ends of the first heat-conducting plate 15 extend to the outside of the air inlet duct 14, and the two ends of the second heat-conducting plate 17 extend to the outside of the connecting bracket 18. The first heat-conducting plate 15, the second heat-conducting plate 17, and the heat-conducting rod 16 are all made of copper.

[0023] Example 2: See Figure 1 , Figure 4 Based on Embodiment 1, the inner diameter of the air inlet duct 14 gradually decreases from the direction near the outer shell 1 to the direction near the inner sleeve 3, so that the cold air can be better blown to the periphery of the motor body 2.

[0024] Please see Figure 1 , Figure 4 The end of the connecting bracket 18 away from the inner sleeve 3 is connected to a support block 19. The end of the support block 19 away from the connecting bracket 18 abuts against the outer wall of the motor body 2. The support block 19 is U-shaped, and several support blocks 19 together support the outer wall of the motor body 2.

[0025] Working principle: In use, open the sealing plate 10, install the motor body 2 into the inner sleeve 3, and extend the output shaft of the motor body 2 from the middle of the end cover 11. After installing the sealing plate 10, external air is delivered to the cooling box 7 by the air pump 8. The incoming air is cooled by the condenser pipe. The air pump 8 blows the cold air into the annular pipe 5 to form cold air. After passing through the annular pipe 5, the cold air is blown out through the air outlet pipe 6 into the air inlet duct 14. The air inlet duct 14 cools the first heat-conducting plate 15 and the second heat-conducting plate 15 is cooled by the heat-conducting rod 16. The cooling plate 17 is used for cooling. The cold air flows from the rear end to the front end of the inner cavity of the outer shell 1 and finally exits from the filter screen 12. The heat is transferred to the outside of the motor body 2 through the second heat conduction plate 17, thereby cooling the outside of the motor body 2. The air cooling is combined with the flow of cold air for heat dissipation. A temperature sensor 13 is installed on the inner wall of the outer shell 1. The temperature sensor 13, the air pump 8, and the condenser 20 are all connected to the control box 9. The temperature sensor 13 detects the real-time temperature inside the outer shell 1. When the temperature is too high, cooling is performed to reduce energy consumption.
