Description

Technical Field

[0001] The utility model relates to the field of servo motors. More specifically, the utility model relates to a servo motor with a heat dissipation structure. Background Art

[0002] When a servo motor is working, it will generate heat. Especially for some high-power servo motors, more heat will be generated during operation. Prolonged use will not only affect the normal use of the motor but also have an impact on the performance of the motor itself, and ultimately reduce the service life of the motor. Therefore, it is necessary to use an external structure to dissipate the heat generated by the servo motor externally to achieve temperature reduction and ensure the safe and stable operation of the servo motor. The heat generated by the servo motor during operation is mainly achieved through the heat exchange between its housing and the outside world. Usually, in order to increase the heat dissipation effect of the housing, heat dissipation fins are also arranged outside the housing for heat dissipation. In addition, a fan can be installed inside the housing to improve the air exchange between the inside of the housing and the outside world to dissipate heat from the motor, and the fan is driven by the rotating shaft of the motor to rotate synchronously to dissipate heat from the motor. For ordinary servo motors, the above heat dissipation means can effectively dissipate heat from the servo motor. However, for high-power servo motors, the heat dissipation effects of simple heat dissipation fins and fans are no longer sufficient to meet the heat dissipation requirements during their operation.
