Patent ID: 7345385

Claim:
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.
