Description

Technical Field

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

[0002] A servo motor is an engine that controls the operation of mechanical components in a servo system. It is an auxiliary motor indirect speed change device. The servo motor can control speed and position with accurate accuracy. It can convert voltage signals into torque and speed to drive the controlled object. Compared with a single asynchronous motor, the servo motor has three significant characteristics: large starting torque, wide operating range, and no self-rotation. The overall heat dissipation of the servo motor is increasingly valued because the efficiency of the overall and output shaft heat dissipation directly affects the motor's operating performance.

[0003] For example, a Chinese patent (CN206962643U) discloses a servo motor spindle heat dissipation device, which includes a heat-conducting ring sleeved on the spindle, and a plurality of heat-dissipating fan blade assemblies extend outward from the outer surface of the heat-conducting ring, and each heat-dissipating fan blade assembly includes two parallel heat sinks; it also includes a disc-shaped heat-dissipating cover, the heat-dissipating cover is provided with an axial hole, the spindle passes through the axial hole of the heat-dissipating cover, and the back of the heat-dissipating cover is provided with a plurality of air inlets, and the air inlets are installed with air inlet pipes; the back of the heat-dissipating cover and the top surface of the motor are fixed by a connecting rod; through the air-cooling heat dissipation method, the heat dissipation of the spindle can be effectively realized, and the spindle temperature can be reduced. The uniquely designed double-leaf structure can quickly take away the heat while reducing the wind resistance coefficient of the spindle and reducing power loss.

[0004] The above scheme also has the following technical defects: the heat dissipation effect of the servo motor is not uniform enough. Since the above scheme adopts air cooling, the air blown by the cooling fan blades can be fully cooled. However, the air is blown to the surroundings. Therefore, there is still a large amount of heat around the servo motor and in places where the cooling fan blades cannot blow. It is difficult to dissipate. Based on this, a servo motor driver heat dissipation structure is proposed. Utility Model Content
