摘要

DYNAMOELECTRIC MACHINE SUPPORT FRAME WITH COPLANAR AND AXIALLY ALIGNED MOUNTING SURFACES A support frame for a dynamoelectric machine having a stator and a rotor supported in bearings mounted in brackets for rotation about a horizontal axis with a uniform air gap between stator and rotor includes a horizontal base member and a pair of axially extending upstanding side walls rigidly connected to the base member and having first and second axially spaced pairs of planar rotor bearing bracket mounting surfaces adjacent opposite ends of the base member with all points thereon in a common horizontal plane and also having first and second axially spaced pairs of planar stator mounting surfaces disposed intermediate the first and second pairs of bracket mounting surfaces with all points thereon in a common horizontal plane. In a preferred embodiment all mounting surfaces on the same lateral side of the frame are axially aligned with one another.
