System for ventilating a motor

1. A system for cooling an electric motor, said system comprising a plurality of components comprising:

a motor stator comprising:

a motor frame comprising a core shell adapted to surround a substantially cylindrical stator core that defines a longitudinal axis of the electric motor, said core shell comprising:

at least four longitudinal panels;

a plurality of apertures located in one or more of said at least four longitudinal panels; and

a first plurality of non-destructively removable plates adapted to effect a first direction of stator core air flow by covering a first selectable sub-plurality of said plurality of apertures, an operative insertion of said first plurality of non-destructively removable plates into said core shell configured to cause a ventilation of the electric motor to be changed from a ventilation scheme whereby cooling air enters from both longitudinal ends of the electric motor and exits via the plurality of apertures to a ventilation scheme whereby the cooling air enters via a first longitudinal end of the electric motor and exits via a second longitudinal end of the electric motor.

2. The system of claim 1 , further comprising:

a second plurality of non-destructively removable plates adapted to effect a second direction of stator core air flow by covering a second selectable sub-plurality of said plurality of apertures.

3. The system of claim 1 , further comprising:

a fan adapted to continuously circulate air along the stator core.

4. The system of claim 1 , further comprising:

a plurality of fans adapted to continuously circulate air along the stator core.

5. The system of claim 1 , further comprising:

a fan adapted to be coupled to a motor rotor and to continuously circulate air along the stator core.

6. The system of claim 1 , further comprising:

a heat exchanger adapted to cool air circulated along the stator core.

7. The system of claim 1 , further comprising:

an air-to-air heat exchanger adapted to cool air circulated along the stator core.

8. The system of claim 1 , further comprising:

a water-to-air heat exchanger adapted to cool air circulated along the stator core.

9. The system of claim 1 , further comprising:

a baffle coupled to said core shell and adapted to effect stator core air flow.

10. The system of claim 1 , further comprising:

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

11. The system of claim 1 , wherein:

said at least four longitudinal panels form a regular polygon.

12. The system of claim 1 , wherein:

said core shell comprises at least six longitudinal panels.

13. The system of claim 1 , wherein:

said core shell comprises at least eight longitudinal panels.

14. The system 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.

15. The system of claim 1 , wherein:

each of the first plurality of non-destructively removable plate is adapted to be removed from a corresponding aperture from said first selectable sub-plurality of apertures.

16. The system of claim 1 , wherein:

at least one of said first plurality of non-destructively removable plates is adapted to cause air to flow across a heat exchanger.

17. The system of claim 1 , wherein:

the motor is a National Electrical Manufacturers Association weather protected Type II motor.

18. The system of claim 1 , wherein:

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

19. The system of claim 1 , wherein:

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

20. The system of claim 1 , wherein:

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