Patent ID: 7348697

Claim:
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.
