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.
Claims19
A ceiling fan motor comprising,
- a stationary stator;
- a rotor mounted for rotary movement about said stator;
- a motor shaft coupled to said stator, said motor shaft having an upper portion extending outwardly from said stator with a plurality of clip mounting slots, said motor shaft also having a clip configured to be mounted to one said slot of said plurality of slots, and
- a motor adapter configured to receive said motor shaft and abut said motor shaft clip and be coupled to a motor housing.
A motor shaft for use with an electric motor having a stationary stator, a rotating rotor, and a motor housing adapter, the motor shaft comprising a middle portion configured to be coupled to the stator of the electric motor, a lower portion extending from said middle portion and adapted to extend downwardly and outwardly from the stator of the electric motor, and an upper portion extending from said middle portion and adapted to extend upwardly and outwardly from the stator of the electric motor and be received within the motor housing adapter, said upper portion having at least two clip channels and a clip configured to be received within one said clip channel and to abut the motor housing adapter coupled to said motor shaft.
A ceiling fan motor comprising,
- a stationary stator;
- a rotor mounted for rotary movement about said stator;
- a motor shaft coupled to said stator, said motor shaft having an upper portion extending outwardly from said stator;
- a motor adapter configured to be received upon said motor shaft, and
- adjustable stop means for limiting the position of said motor adapter along said motor shaft, said stop means including a stop configured to be coupled to said motor shaft at a plurality of pre-selected longitudinal positions along said motor shaft.
A method of manufacturing a ceiling fan comprising the steps of:
- (A) providing an electric motor having a motor shaft with a plurality of clip channels and a clip configured to be received within a clip channel;
- (B) providing a motor adapted configured to mate with the motor shaft;
- (C) providing a motor housing adapted to mate with the motor adapter;
- (D) selecting a clip channel from the plurality of clip channels to provide a proper spacing between the motor and the motor housing;
- (E) positioning the clip within the selected clip channel;
- (F) mounting the motor adapter to the motor shaft in a position to abut the clip, and
- (G) coupling the motor housing to the motor adapter.
