This invention provides an electric motor for high speed operation that includes an inner housing assembly made up of two members having tubular walls having telescoped sections bonded together at the central portion of the assembly, with the field of motor bonded to the inside of the two inner housing members. The opposite ends of the inner housing assembly then are bored to provide precisely aligned bearing support 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 an unobstructed annular passageway for circulating coolant. The passageway includes inwardly directed portions around the bearings for efficient removal of heat from those areas.
