Description

Technical Field

[0001] This utility model relates to the field of servo motor technology, specifically a high-protection, high-power servo motor. Background Technology

[0002] A servo motor is a high-precision drive device that integrates precision mechanics, power electronics, and intelligent control. It consists of a permanent magnet synchronous motor body, a photoelectric / magnetic encoder, and a drive controller, forming a closed-loop control system. It achieves ±0.01° angle resolution and millisecond-level dynamic response by real-time feedback of speed / position signals.

[0003] When a high-power servo motor is working, the current is large, and the current passing through the windings generates a lot of heat, increasing the internal heat of the servo motor. However, due to the structural design of the high-power servo motor, its heat dissipation area is relatively limited, and the generated heat cannot be dissipated in time, causing heat accumulation and temperature rise. This leads to the accelerated aging of the insulation material inside the motor at high temperatures, shortening its service life. When the temperature exceeds the allowable temperature of the insulation material, the insulation performance will drop sharply, affecting the normal operation of the internal components of the servo motor. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a high-protection, high-power servo motor to solve the problem mentioned in the background art that the insulation material inside the motor ages faster at high temperatures, shortening its service life, and that the insulation performance drops sharply when the temperature exceeds the allowable temperature of the insulation material, affecting the normal operation of the internal components of the servo motor.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-protection, high-power servo motor, comprising:

[0008] A servo motor housing, wherein a stator winding is installed inside the servo motor housing, a stator core is installed on the surface of the stator winding, and a rotor is installed on the surface of the servo motor housing;

A semiconductor refrigeration module is installed on the upper surface of the cooling box. A centrifugal coolant pump is installed at the outlet of the cooling box. A coolant channel is installed at the outlet of the centrifugal coolant pump. The coolant channel has a threaded design and is installed inside the servo motor housing. The outlet of the coolant channel is connected to the inlet of the cooling box.

[0010] A sealing assembly is disposed on the surface of the inlet and outlet ends of the coolant channel. The sealing assemblies are all mounted on the upper surface of the servo motor housing. Each sealing assembly has a sealing ring installed inside it, and the inner ring of the sealing ring is in contact with the surface of the coolant channel.

[0011] Preferably, the upper surface of the sealing assembly is equipped with a limiting cylinder, and the sealing rings are inserted into the inside of the limiting cylinder, which allows for easy replacement of the sealing rings.

[0012] Preferably, the upper surface of the limiting cylinder is uniformly provided with extrusion plates, and each extrusion plate has a threaded groove. A nut is screwed onto the outer ring of the extrusion plate. The nut can extrude the extrusion plate, thereby extruding the sealing ring. This allows the sealing ring to make tight contact with the surface of the coolant channel, thus sealing the connection between the coolant channel and the servo motor housing.

[0013] Preferably, a support base is installed at the bottom of the servo motor housing, and a buffer pad is installed at the contact portion between the support base and the servo motor housing, which can buffer the vibration of the servo motor housing.

Furthermore, a semiconductor cooling module maintains the coolant in the cooling tank at a low temperature, effectively reducing the motor's operating temperature, improving its reliability and lifespan, and guaranteeing the normal operation of the internal components. This provides high protection for the servo motor's internal components. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a technical solution: a high-protection, high-power servo motor. Please refer to [link / reference needed]. Figure 1 The servo motor housing 1 includes a stator winding installed inside the servo motor housing 1, a stator core installed on the surface of the stator winding, and a rotor 2 installed on the surface of the servo motor housing 1.

[0026] Cooling box 3 is located on the upper surface of servo motor housing 1. Please refer to [link / reference]. Figure 3 The cooling tank 3 contains coolant. A semiconductor refrigeration module 31 is mounted on the upper surface of the cooling tank 3. A centrifugal coolant pump 4 is installed at the outlet of the cooling tank 3. A coolant channel 5 is installed at the outlet of the centrifugal coolant pump 4. The coolant channel 5 has a threaded design. Please refer to [link / reference needed]. Figure 2 The coolant channel 5 is installed inside the servo motor housing 1, and the outlet of the coolant channel 5 is connected to the inlet of the cooling tank 3.

[0027] Please see Figure 3 The sealing assembly 6 is disposed on the surface of the inlet and outlet ends of the coolant channel 5. Both sealing assemblies 6 are mounted on the upper surface of the servo motor housing 1. (See also...) Figure 5 Each sealing component 6 has a sealing ring 7 installed inside, and the inner ring of the sealing ring 7 is in contact with the surface of the coolant channel 5.

[0028] Starting the centrifugal coolant pump 4 can inject the coolant in the cooling tank 3 into the coolant channel 5. The coolant channel 5 has a threaded design, which can evenly dissipate heat from the inside of the servo motor. Furthermore, the semiconductor cooling module 31 can ensure that the coolant in the cooling tank 3 is kept at a low temperature, so that the coolant channel 5 can effectively reduce the temperature of the motor during operation, thereby improving the reliability and service life of the motor.

[0029] Limiting cylinders 8 are installed on the upper surface of the sealing assembly 6, and sealing rings 7 are inserted into the inside of the limiting cylinders 8, which makes it easy to replace the sealing rings 7.

[0030] The upper surface of the limiting cylinder 8 is evenly provided with extrusion plates 9, and the surface of each extrusion plate 9 is provided with threaded grooves. A nut 10 is screwed onto the outer ring of the extrusion plate 9. The nut 10 can extrude the extrusion plate 9, thereby extruding the sealing ring 7, so that the sealing ring 7 can be in close contact with the surface of the coolant channel 5, and can seal the connection between the coolant channel 5 and the servo motor housing 1.

[0031] Please see Figure 1 The bottom of the servo motor housing 1 is equipped with a support base 11, please refer to [link / reference]. Figure 4 A buffer pad 12 is installed at the contact part between the support base 11 and the servo motor housing 1, which can buffer the vibration of the servo motor housing 1.

[0032] Please see Figure 3 A heat sink 13 is installed on the upper surface of the cooling box 3. A fan 14 is installed at the air outlet of the heat sink 13. The fan 14 can cool the semiconductor cooling module 31.

[0033] In operation, this solution works as follows: First, the centrifugal coolant pump 4 is started to inject coolant from the cooling tank 3 into the coolant channel 5. The coolant channel 5 has a threaded design, which can evenly dissipate heat from the inside of the servo motor. Then, the semiconductor cooling module 31 ensures that the coolant in the cooling tank 3 is at a low temperature. The fan 14 cools the semiconductor cooling module 31, so that the coolant channel 5 can effectively reduce the temperature during motor operation, improve the reliability and service life of the motor. Finally, the nut 10 can compress the extrusion plate 9, which in turn compresses the sealing ring 7, so that the sealing ring 7 can make tight contact with the surface of the coolant channel 5, and seal the connection between the coolant channel 5 and the servo motor housing 1.
