Abstract
Submersible electric motors for pumping fluid from wells are assembled together in tandem relationship for increasing total output horsepower. Means are provided to make electrical connections just prior to assembly and interconnect the oil flow corridors between motors during assembly. Precompressed spring-loaded thrust bearings compensate for shaft length changes and dampen vibrations. The oil circulation corridors include filtration.
