摘要

A motor comprising two or more sections, each section comprising:
a submersible tubular housing;
a stator core disposed within the housing and having one or more lobes, each lobe having a winding wrapped therearound; and
a rotor disposed within the housing and comprising a shaft and a rotor core, the rotor core having two or more lobes,
wherein each section is incrementally oriented so that the sections may be operated to mimic a multi-phase motor.
Preferred application to the dewatering of gas wells.
