It should be understood that the sequence of the liquid medicine entering the motor and the electronic speed regulator can be selected according to actual conditions, for example, the sequence can be selected according to positions, and also can be selected according to cooling requirements, which is not specifically limited in the present application. When the position according to electron speed regulator and motor is selected, can consider the convenience that the pipeline set up, for example, the liquid medicine reachs the electron speed regulator at first, then gets into the motor, and the process of also cooling is at first cooling the electron speed regulator, then gets into the motor and cools down the motor. When selecting according to the cooling demand, can consider the size of calorific capacity, for example, if the motor is bigger for electronic governor calorific capacity, more heat need be taken away, more heat can be taken away to the liquid medicine can pass through the motor earlier, can take away more heat, and electronic governor is lower relatively the demand of cooling, and the liquid medicine rises to motor cooling back temperature, still can satisfy electronic governor's cooling demand.
