Combined shell for air cooling servo motor

The invention provides a combined shell for an air cooling servo motor, and relates to the field of motor shells, the combined shell comprises a main shell, the main shell is cylindrical, the main shell is provided with ventilation holes, the ventilation holes penetrate through the front end and the rear end of the main shell, the ventilation holes are annularly distributed, and a plurality of heat conduction pipes are embedded in the main shell. And the plurality of heat conduction pipes are arranged in parallel and are arc-shaped. According to the combined shell for the air cooling servo motor, the annular air channel is formed in the inner side of the main shell through the annularly-distributed ventilation holes, the ventilation holes are arranged to be in a regular hexagon shape and are arranged in a honeycomb shape, the contact area between the inner walls of the ventilation holes and airflow can be greatly increased, and therefore the heat dissipation area is greatly increased, and the service life of
