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