ABSTRACT:
A motor comprising a stator core having stator windings wound thereon and an elongated outer shell which surrounds the core and the windings, the shell extending lengthwise beyond the end turns of the windings and supporting the motor bearings. The core is slidable in the shell but is retained in place in the lengthwise direction by first and second abutments fastened to the interior of the shell at opposite ends of the stator. At least one of the abutments is a ring which may be removed, thereby enabling easy assembly or disassembly of the motor. The core is retained against angular movement by a key which engages lengthwise extending keyways in the core and the shell. Tubular spacers are mounted between the stator core and the abutments.
