Abstract: A motor casing includes a frame assembly and a motor base. The frame assembly includes a frame having an inner face defining an air channel, and a plurality of connection members disposed in the air channel. Each connection member has first and second ends. The first ends of the connection members are coupled to the inner face of the frame. The motor base includes a supporting member and a covering member. The supporting member has an inner surface defining a through-hole, and an outer surface coupled with the second ends of the connection members. An opening portion and a coupling portion are formed at two sides of the through-hole. The covering member is coupled to the opening portion of the supporting member and has first and second surfaces. The first surface faces the through-hole of the supporting member. The covering member includes at least one vent.

Abstract: A motor base comprises a supporting member and an enclosure member. The supporting member has an outer surface and an inner surface, wherein the inner surface defines a through-hole. One side of the through-hole forms an opening portion and another side of the through-hole forms a coupling portion. The enclosure member is coupled to the opening portion of the supporting member and has a first surface and a second surface opposing to the first surface. The first surface faces the through-hole of the supporting member. The enclosure member further comprises at least one vent extending from the first surface to the second surface thereof.
