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. The outer-periphery of the support portion is made resilient, preferably by the provision of resilient elements about its periphery. For example, a plurality of wheels may be disposed on the outer periphery. 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 for deflection or supported in elastomeric bushings or, alternatively, the axle is supported in a cantilever fashion. Wheels may also be formed of a compressible elastomeric material. Alternatively, a structural spring may be provided at the outer periphery of the support position of the bearing.
