Abstract
A ceiling fan motor structure includes a housing, a magnetic ring, and a cover. The housing has an annular wall and a shielding plate which jointly define a receiving room. The open side of the annular wall forms an opening. The housing has an annular edge around the opening. The annular wall has a plurality of projections projecting from the inner wall surface of the receiving room. The magnetic ring has a plurality of recesses on its outer periphery and is placed into the receiving room of the housing in a way in which the recesses are respectively aligned with the projections and in which each projection is placed in the corresponding recess to prevent relative rotation between the magnetic ring and the housing. The cover closes the opening and is fixedly connected to the housing.
