ABSTRACT:
An elongated electric motor having an annular stator with laminations and a segmented rotor on a shaft bearing assemblies provided between the rotor segments support the shaft and rotor. The bearing assemblies include a sleeve for supporting the shaft and a support portion adjacent the stator with a plurality of wheels to disposed thereon. The wheels inhibit rotation of the bearing while at the same time permitting easy longitudinal movement of the bearing relating to the stator. The wheels are provided with a spring characteristic by mounting on an axle which is supported in elastomeric bushings or, alternatively, the axle is supported in a cantilever fashion. The wheels may also be formed of a compressible elastomeric material.
