Abstract

A ceiling fan assembly having a motor with a rotor and a stator, at least one blade operably coupled to the stator, a motor shaft extending from the stator and having an internal wire passage and a wire opening in a side of the motor shaft, with the wire opening providing access to the internal wire passage, a control mounting plate having a motor shaft opening through which the motor shaft extends and an electronic control unit carried by a side of the control mounting plate.

Claims (51)

1. A ceiling fan assembly comprising:

a motor having a rotor and a stator;

at least one blade operably coupled to the motor;

a motor shaft extending from the stator and having a peripheral side terminating at opposing ends to define an internal wire passage and a wire opening in the peripheral side, with the wire opening providing access to the internal wire passage;

a control mounting plate having a motor shaft opening through which the motor shaft extends, with the motor shaft opening being sized to define gap between motor shaft and the control mounting plate, with the control mounting plate and the gap extending entirely circumferentially around the motor shaft, and the control mounting plate is located, relative to the motor shaft, between the wire opening and the rotor and stator, the control mounting plate having opposing first and second sides, with the first side oriented toward the wire opening and the second side oriented toward the rotor and stator;

an electronic control unit carried by a first side of the control mounting plate and electrically connected to the motor by wires passing through the wire opening and wire passage; and

a multiple segment plug occluding the gap.

2. The ceiling fan assembly of claim 1 wherein at least one of the multiple segments is mounted to the motor shaft.

3. The ceiling fan assembly of claim 2 wherein all of the multiple segments are mounted to the motor shaft.

4. The ceiling fan assembly of claim 1 wherein at least two of the multiple segments have overlapping portions.

5. The ceiling fan assembly of claim 4 wherein at least one of the overlapping portions is a step.

6. The ceiling fan assembly of claim 5 wherein another of the overlapping portions resides above the step.

7. The ceiling fan assembly of claim 1 wherein at least one of the multiple segments defines at least a portion of a collar circumscribing the motor shaft.

8. The ceiling fan assembly of claim 7 wherein all of the multiple segments have a portion, which collectively defines the collar.

9. The ceiling fan assembly of claim 7 wherein the collar has a cut out portion corresponding to the wire opening.

10. The ceiling fan assembly of claim 1 wherein at least one of the multiple segments comprises an indexing rib receiving within the motor shaft opening.

11. The ceiling fan assembly of claim 10 wherein all of the multiple segments comprise an indexing rib, which collective have a peripheral shape complementary to the motor shaft opening.

12. The ceiling fan assembly of claim 1 wherein at least one of the multiple segments is located on the second side of the control mounting plate.

13. The ceiling fan assembly of claim 12 wherein all of the multiple segments are located on the second side.

14. The ceiling fan assembly of claim 1 wherein the multiple segments comprise two segments.

15. The ceiling fan assembly of claim 14 wherein the two segments collectively define a periphery complementary with the shape of the motor shaft opening.

16. The ceiling fan assembly of claim 15 wherein the periphery is a circle.

17. The ceiling fan assembly of claim 16 wherein the two segments form equal halves of the circle.

18. A ceiling fan assembly comprising:

a motor having a rotor and a stator;

at least one blade operably coupled to the motor;

a motor shaft extending from the stator and having a peripheral side terminating at opposing ends to define an internal wire passage and a wire opening in the peripheral side, with the wire opening providing access to the internal wire passage;

a control mounting plate having a motor shaft opening through which the motor shaft extends, with the motor shaft opening being sized to define gap between motor shaft and the control mounting plate, and the control mounting plate is located, relative to the motor shaft, between the wire opening and the rotor and stator, the control mounting plate having opposing first and second sides, with the first side oriented toward the wire opening and the second side oriented toward the rotor and stator;

an electronic control unit carried by a first side of the control mounting plate and electrically connected to the motor by wires passing through the wire opening and wire passage; and

a multiple segment plug occluding the gap and all of the multiple segments have a portion, which collectively define a collar circumscribing the motor shaft.

19. A ceiling fan assembly comprising:

a motor having a rotor and a stator;

at least one blade operably coupled to the motor;

a motor shaft extending from the stator and having a peripheral side terminating at opposing ends to define an internal wire passage and a wire opening in the peripheral side, with the wire opening providing access to the internal wire passage;

a control mounting plate having a motor shaft opening through which the motor shaft extends, with the motor shaft opening being sized to define gap between motor shaft and the control mounting plate, and the control mounting plate is located, relative to the motor shaft, between the wire opening and the rotor and stator, the control mounting plate having opposing first and second sides, with the first side oriented toward the wire opening and the second side oriented toward the rotor and stator;

an electronic control unit carried by a first side of the control mounting plate and electrically connected to the motor by wires passing through the wire opening and wire passage; and

a multiple segment plug occluding the gap wherein at least one of the multiple segments comprises an indexing rib receiving within the motor shaft opening.

20. A ceiling fan assembly comprising:

a motor having a rotor and a stator;

at least one blade operably coupled to the motor;

a motor shaft extending from the stator and having a peripheral side terminating at opposing ends to define an internal wire passage and a wire opening in the peripheral side, with the wire opening providing access to the internal wire passage;

a control mounting plate having a motor shaft opening through which the motor shaft extends, with the motor shaft opening being sized to define gap between motor shaft and the control mounting plate, and the control mounting plate is located, relative to the motor shaft, between the wire opening and the rotor and stator, the control mounting plate having opposing first and second sides, with the first side oriented toward the wire opening and the second side oriented toward the rotor and stator;

an electronic control unit carried by a first side of the control mounting plate and electrically connected to the motor by wires passing through the wire opening and wire passage; and

a multiple segment plug occluding the gap wherein all of the multiple segments are located on the second side of the control mounting plate.

21. A ceiling fan assembly comprising:

a motor having a rotor and a stator;

at least one blade operably coupled to the motor;

a motor shaft extending from the stator and having a peripheral side terminating at opposing ends to define an internal wire passage and a wire opening in the peripheral side, with the wire opening providing access to the internal wire passage;

a control mounting plate having a motor shaft opening through which the motor shaft extends, with the motor shaft opening being sized to define gap between motor shaft and the control mounting plate, and the control mounting plate is located, relative to the motor shaft, between the wire opening and the rotor and stator, the control mounting plate having opposing first and second sides, with the first side oriented toward the wire opening and the second side oriented toward the rotor and stator;
