Abstract

A motor includes two or more sections. Each section includes a submersible tubular housing and a stator core disposed within the housing. The stator core has one or more lobes and each lobe has a winding wrapped therearound. The motor further includes a rotor disposed within the housing and including a shaft and a rotor core. The rotor core has two or more lobes. Each section is incrementally oriented so that the sections may be operated to mimic a multi-phase motor.
