Abstract
A multi-phase, inductive coupling first portion is carried by a tubular. The coupling first portion is configured to inductively transmit current with a corresponding multi-phase, inductive coupling second portion. A downhole-type electric stator is carried by the tubular and is configured to receive and electromagnetically interact with an electric rotor-impeller. The coupling first portion is electrically connected to windings of the stator.
