[0002] The control motor serves as an actuator, a detection element, and an arithmetic element in the control system. In terms of working principle, there is no essential difference between a micro-control motor and an ordinary motor, but they are different in terms of usage functions. Ordinary motors have a large power and focus on performance indicators such as starting, running, and braking of the motor, while the control motor has a smaller output power and focuses on the control accuracy, response speed, and operation reliability of the motor. There are many types of micro-control motors produced at home and abroad with different functions.

[0003] However, at present, the heat dissipation water channels for power devices are mostly formed by casting.

Moreover, once the casting mold is finalized, it cannot be changed. If the heat dissipation is insufficient, it cannot be further adjusted. Therefore, a heat dissipation water channel that can be machined is designed. Summary of the Utility Model
