Abstract
This application provides a motor shell, manufacturing method of motor shell, and electric fan. The motor shell includes an outer shell and a connecting part. The outer shell defines a holding cavity with an opening at one end of it. The connecting part extends along an axial direction of the outer shell on the holding cavity. The connecting part defines a matching surface which is at one end of the connecting part away from the bottom wall of the holding cavity. The matching surface is configured to abut against an inner ring of a bearing. A beneficial effect of this application is that a flatness of the matching surface is easier to improve, which is conducive to increasing a contact area between the matching surface and the inner ring, improving supporting effects of the bearing, reducing skids of the bearing and wears caused by the skids.
