Abstract
A system for operating in a wellbore in a subterranean formation is described. The system includes a housing, a rotor, a stator, and a controller. The rotor is within the housing and includes a rotatable shaft, a fluid impeller, and a magnetic field source. The magnetic field source is configured to generate a net magnetic field around an entire circumference of the rotor that is uniformly polarized in a single orientation. The stator is within the housing and laterally surrounds the rotatable shaft. The stator is configured to conduct the generated magnetic field to produce a voltage waveform signal. The controller is communicatively coupled to the stator. The controller is configured to receive the voltage waveform signal from the stator and determine an operating characteristic of the rotor based on the received voltage waveform signal.
