Abstract
A laminated stator assembly for an electric motor includes plate laminations which have square-trimmed edge segments separated by circular peripheral edge sectors, which plates are randomly oriented in assembling the stator to provide a generally cylindrical outer surface. In this manner, the stator can be enclosed in and supported by an outer motor shell or housing which is substantially thinner and less expensive. The stator assembly of the present invention enjoys the material savings and enhanced air cooling characteristics of prior art stator constructions utilizing square-trimmed laminations, but eliminates the detrimental aspects of difficult alignment and heavier motor housings. In addition, overall stator assembly is substantially simplified.
