[0007] The motor is vertically arranged and fixedly connected to the connecting base, so that the motor is suspended in the air, and a circle of feet is arranged at the bottom of the base, so that there is a gap between the base and the workbench, so that the inside of the casing is in direct contact with the outside through the gap, which effectively accelerates the heat dissipation of the motor and improves the working stability and life of the motor.

[0008] At the same time, the motor is basically contained in the thin-walled cylinder, so as to utilize the extremely thin cylinder wall of the thin-walled cylinder to accelerate the heat transfer speed between the inside and outside of the casing, thereby further accelerating the heat dissipation of the motor.
