Abstract

Certain exemplary embodiments comprise a system comprising: a motor stator comprising: a motor frame comprising a core shell adapted to surround a stator core comprising: a plurality of panels; a plurality of apertures located in one or more of said panels; and a first plurality of non-destructively removable plates adapted to effect a first direction of stator core air flow by impeding airflow through a first selectable sub-plurality of said plurality of apertures.

Claims (43)

1. A method for cooling a motor, said method comprising a plurality of activities comprising:

operating a motor that defines a longitudinal axis, the motor comprising a stator core surrounded by a core shell, the core shell comprising:

at least four longitudinal panels;

a plurality apertures located in one or more of the at least four longitudinal panels, the plurality of apertures adapted to be covered by a plurality of non-destructively removable plates adapted to, said plurality of plates adapted to change ventilation of the motor from an X ventilation scheme to a Z ventilation scheme, the X ventilation scheme comprising cooling air entering the motor from both longitudinal ends of the motor, flowing parallel to a longitudinal co-axis of, and between, the rotor and stator, radially through the stator, and substantially exiting via one or more apertures in the core shell, the Z ventilation scheme comprising cooling air entering the motor from a first longitudinal end, flowing axially and parallel to a longitudinal co-axis of, and between, the rotor and stator, and substantially exiting via a second longitudinal end on an opposing end of the motor from the first longitudinal end; and

covering a first selected sub-plurality of said plurality of apertures with a first sub-plurality of said plurality of non-destructively removable plates.

2. The method of claim 1 , further comprising:

removing the first sub-plurality of non-destructively removable plates from the first selected sub-plurality of apertures.

3. The method of claim 1 , further comprising:

relocating the first sub-plurality of non-destructively removable plates to a second selected sub-plurality of apertures.

4. The method of claim 1 , further comprising:

covering a second selected sub-plurality of apertures.

5. The method of claim 1 , further comprising:

covering a second selected sub-plurality of apertures with a second sub-plurality of non-destructively removable plates adapted to effect a second direction of air flow across the stator core.

6. The method of claim 1 , further comprising:

circulating air along the stator core of the motor.

7. The method of claim 1 , further comprising:

operating a fan attached to a rotor of the motor.

8. The method of claim 1 , further comprising:

operating a fan attached to a rotor of the motor, the fan adapted to circulate air along the stator core of the motor.

9. The method of claim 1 , further comprising:

effecting air flow within the care shell.

10. The method of claim 1 , further comprising:

adjusting a baffle coupled to the core shell, the baffle adapted to effect stator core air flow.

11. The method of claim 1 , further comprising:

adjusting a baffle comprised by the motor, the baffle adapted to effect stator core air flow.

12. The method of claim 1 , further comprising:

causing stator care cooling air to flaw across a heat exchanger.

13. The method of claim 1 , wherein:

the care shell comprises at least six longitudinal panels.

14. The method of claim 1 , wherein:

the core shell comprises at least eight longitudinal panels.

15. The method of claim 1 , wherein:

each of the at least four longitudinal panels has a longitudinal dimension, the plurality of longitudinal dimensions of the at least four longitudinal panels being substantially equal.

16. The method of claim 1 , wherein:

the at least four longitudinal panels define a regular polygon.

17. The method of claim 1 , wherein:

a configuration of the motor qualifies as a National Electrical Manufacturers Association weather protected enclosure.

18. The method of claim 1 , wherein:

a configuration of the motor qualifies the motor as a National Electrical Manufacturers Association weather protected motor.

19. The method of claim 1 , wherein:

a configuration of the motor qualifies the motor as a Totally Enclosed Air-to-Air Cooled motor.

20. The method of claim 1 , wherein:

a configuration of the motor qualifies the motor as a Totally Enclosed Water-to-Air Cooled motor.
