Title: Innovations of Jeffrey H Campau

Introduction

Jeffrey H Campau is an accomplished inventor based in Pinckney, MI (US). He holds a total of 4 patents that showcase his expertise in the field of centrifugal pump systems. His innovative designs focus on enhancing the efficiency and functionality of these systems through advanced magnetic structures.

Latest Patents

One of his latest patents is titled "Impeller position compensation using field oriented control." This invention involves a centrifugal pump system that features an impeller rotating with first and second magnetic structures on opposite surfaces. A levitation magnetic structure is positioned at one end of the pump housing, creating a levitating magnetic field that axially attracts the first magnetic structure. Additionally, a multiphase magnetic stator at the opposite end generates a rotating magnetic field to attract the second magnetic structure. The system includes a commutator circuit that provides multiple phase voltages to the stator, while a sensing circuit determines the respective phase currents. A controller calculates commanded values for the phase voltages based on the determined phase currents and a variable commutation angle, ensuring the impeller remains centered within the pumping chamber.

Another significant patent by Campau is the "Startup sequence for centrifugal pump with levitated impeller." This invention also features an impeller with magnetic structures and a levitation magnetic structure. The multiphase magnetic stator generates a rotating magnetic field, and the commutator circuit supplies phase voltages to the stator. The controller in this system determines the commanded values of the phase voltages during operation, responding to the desired impeller speed and actual impeller phase.
