ABSTRACT:
A reliable long-life subfractional horsepower electric motor comprising stator and rotor assemblies The stator assembly includes injection molded thermoplastic end housings and plastic bearing inserts shrink fitted into the end housings. The rotor assembly includes a shaft with a special ground finish that affords a long service life and the bearing material includes solid lubricant that coats the shaft to make it corrosion resistant thereby allowing the shaft to be made of inexpensive material such as plain carbon steel. The disclosed motor construction affords a significant reduction in the number of parts and production procedures as compared to prior art long-life motors to effect a significant reduction in manufacturing cost.
