<p>59-GM-289 LAMINATED ROTOR FOR A DYNAMOELECTRIC MACHINE WITH COOLANT PASSAGEWAYS THEREIN A laminated rotor for a dynamoelectric machine characterized by requiring and incorporating only two differently configured sets of rotor laminations to afford axial and radial coolant passageways through the rotor. Each lamination in the respective sets is provided with punched apertures that form, respectively, conductor sots arcuately spaced around its periphery, and is further provided with a plurality of axial coolant passageways near its inner diameter. Each lamination in one of the sets of laminations also includes a plurality of arcuately spaced radial ducts, each disposed between a respective pair of conductor slots. The axial coolant passageways in one set of laminations are arranged to overlap a predetermined portion of the inner ends of the radial ducts in the other set of laminations to enable cooling air to be forced through the axial coolant passageways into the radial ducts and thence into the air gap of the machine when the sets of laminations are stacked to form a rotor that is then mounted in operating position, relative to an associated stator.</p> |
