It will be appreciated that in the actual assembly process, the two conductive columns 120, the signal connection member 130 and the air pipe connection member 140 are all installed on the connection barrel 110, when the integrated liquid cooling motor is assembled, one end of the two conductive columns 120 can be directly connected with the positive terminal and the negative terminal of the motor, one end of the signal connection member 130 is connected with the control board of the integrated liquid cooling motor, one end of the air pipe connection member 140 is connected with the internal air circuit pipeline of the integrated liquid cooling motor, and connection of the internal circuit and the external circuit of the integrated liquid cooling motor is realized through the conductive columns 120, the signal connection member 130 and the air pipe connection member 140 which are arranged on the connection barrel 110.

Since the connection cylinder 110 is used as the outlet support structure, it is unnecessary to punch holes in the stator shaft 200 as in the prior art, which is advantageous in ensuring the strength of the stator shaft 200 of the integrated liquid-cooled motor.
Optionally, the connecting cylinder 110 is a steel cylinder, and is responsible for connecting a motor circuit and a gas circuit and also plays a role of bearing the stator shaft 200 to some extent. Of course, the material of the connecting cylinder 110 can be selected according to actual needs.
