摘要：This invention provides an electric motor for high speed operation that includesan inner housing assembly made up of two members having tubular walls havingtelescoped sections bonded together at the central portion of the assembly, with thefield of motor bonded to the inside of the two inner housing members. The oppositeends of the inner housing assembly then are bored to provide precisely aligned bearingsupport surfaces. Ball bearings fit on these surfaces and rotatably mount the armature.An outer housing fits around the inner housing and is spaced from it, providing anunobstructed annular passageway for circulating coolant. The passageway includesinwardly directed portions around the bearings for efficient removal of heat from thoseareas.
