Abstract
Abstract A dynamoelectric machine mounting assembly is provided with a plurality of adaptors positioned at spaced locations adjacent to the perimeter of a generally cylindrical frame of a dynamoelectric machine having a central axis. At least one end of each of the adaptors is attached to the frame and a band encircles the frame and the adaptors and exerts a radially inward force on the adaptors. Means are provided for connecting the band to an external structure. By mounting the adaptors on the frame such that one end of each adaptor is radially spaced from the frame, a tapered gap is formed between that end of the adaptor and the frame such that when the adaptor is subjected to a radially inward force from the band, the central portion of the adaptor can deform radially inward without contacting the periphery of the machine frame.
