Abstract: A ceiling fan motor (10) is disclosed which is coupled to a motor adapter (14) which in turn is coupled to a downrod (12) and motor housing (13). The motor adapter 14 has a downrod receiver (45), a motor shaft receiver (46), and three mounting arms (47). The downrod receiver is defined by a tubular cylindrical wall (52) which has a first set screw hole (58) and a threaded, second set screw hole (59) which are aligned with downrod set screw holes (60). The cylindrical wall includes ridges (61) which are positioned on either side of the second set screw hole (59). A threaded set screw (62) extends through the first set screw hole, through the downrod set screw holes, and threaded into the second set screw hole. The threaded set screw has a head (63) with a tapered portion (64) which abuts the downrod.

Abstract: A ceiling fan motor (10) is disclosed which is coupled to a motor adapter (11) which in turn is coupled to a downrod (12) and motor housing (13). The ceiling fan motor has a stationary stator (17) and a rotor (18). A motor shaft (20) is coupled to the stator. The motor shaft has an upper portion (23), a middle portion (24), and a lower portion (25). The shaft upper portion has a helical thread (28) and five C-clip spaces (29) which are longitudinally spaced from each other. A C-clip (31) is fitted into one of the five C-clip spaces. The C-clip is configured to abut the bottom surface (32) of the motor adapter to limit the downward movement and position of the motor adapter upon the motor shaft.
