Abstract

A bracket for mounting a motor protector on an endshield of a motor comprises a tube sized and shaped for receiving the protector. The tube includes at least one integrally formed fastener for fastening the protector to the bracket. At least one integrally formed projection extends outwardly from the tube to facilitate fastening the bracket to the endshield of the motor.

Claims (50)

1. A bracket for mounting a motor protector on an endshield of a motor comprising:

a tube sized and shaped for receiving the protector, the tube including:

at least one integrally formed fastener for fastening the protector to the bracket,

at least one integrally formed projection extending outwardly from the tube to facilitate fastening the bracket to the endshield of the motor.

2. The bracket of claim 1 wherein an end of the tube includes an integrally formed wall having a hole therethrough for receiving a manual reset of the motor protector.

3. The bracket of claim 2 wherein the tube is formed of a flame retardant material.

4. The bracket of claim 3 wherein the flame retardant material is an injection molded plastic and is electrically insulating.

5. The bracket of claim 1 wherein an end of the tube is open for receiving the motor protector.

6. The bracket of claim 1 wherein the tube comprises two of the integrally formed projections, each projection shaped to engage the endshield.

7. The bracket of claim 6 wherein each projection includes a hole for receiving a fastener therethrough, the fastener mating with the endshield of the motor.

8. The bracket of claim 7 wherein there is no gasket between the end of the tube and the endshield.

9. The bracket of claim 1 wherein the tube includes two of the integrally formed fasteners, each fastener including a detent for mating with a portion of the protector.

10. An electric motor comprising:

a rotor,

a stator in magnetic coupling relation to the rotor and having windings,

a housing surrounding the stator and rotor,

an endshield disposed at an end of the rotor and stator and attached to an end of the housing,

a motor protector for protecting the motor from damage, and

a bracket securing the motor protector to the endshield,

the bracket being formed of a flame retardant material.

11. The electric motor of claim 10 wherein the bracket comprises a tube sized and shaped for receiving the protector and having first and second ends, the tube including:

at least one integrally formed fastener adjacent the second end of the tube for fastening the protector to the bracket,

at least one integrally formed projection extending outwardly from the tube to facilitate fastening the bracket to the endshield.

12. The electric motor of claim 11 wherein the second end of the tube includes an integrally formed wall for at least partially closing the second end of the tube.

13. The electric motor of claim 12 wherein the protector includes a manual reset button.

14. The electric motor of claim 13 wherein the wall includes an opening for receiving the button.

15. The electric motor of claim 12 wherein the first end of the tube includes an opening for receiving the motor protector.

16. The electric motor of claim 11 wherein the tube comprises two of the integrally formed projections, each projection shaped to engage an endshield of the motor.

17. The electric motor of claim 16 wherein each projection includes a hole for receiving a fastener therethrough, the fastener mating with the endshield of the motor.

18. The electric motor of claim 16 wherein the second end of the tube is shaped to engage the endshield.

19. The electric motor of claim 11 wherein the tube includes two of the integrally formed fasteners, each fastener including a detent for mating with a portion of the protector.

20. An electric motor comprising:

a rotor,

a stator in magnetic coupling relation to the rotor and having windings,

an endshield disposed at an end of the rotor and stator,

a housing receiving the rotor and stator,

a manual reset motor protector for protecting the motor from damage, and

a bracket receiving the protector and securing the motor protector to the endshield,

the bracket comprising a tube having an open end for receiving the protector and an opposite end having a hole sized to receive a reset button of the protector,

the bracket including integral detents, each detent mating with a portion of the protector,

the bracket including outwardly extending ears having holes therethrough for receiving fasteners that extend into the endshield,

the bracket being formed of an electrically insulating, flame retardant material.

21. An electric motor comprising:

a rotor;

a stator in magnetic coupling relation to the rotor and having windings;

an endshield disposed at an end of the rotor and stator;

a motor protector for protecting the motor from damage, the motor protector including a manual reset button; and

a bracket securing the motor protector to the endshield and formed of a flame retardant material, the bracket comprising a tube sized and shaped for receiving the protector, the tube including: (a) first and second ends; (b) at least one integrally formed fastener adjacent the second end of the tube for fastening the protector to the bracket; and (c) at least one integrally formed projection extending outwardly from the tube to facilitate fastening the bracket to the endshield,

wherein the second end of the tube includes an integrally formed wall for at least partially closing the second end of the tube.

22. The electric motor of claim 21 wherein the wall includes an opening for receiving the button.
