CERRITOS, Calif. – May 7, 2019 – Upwing Energy, an artificial lift technology company and a subsidiary of Calnetix Technologies, announced today that Calnetix’s Principal Research Engineer Alexei Filatov will present at the International Electric Machines and Drive Conference (IEMDC) in San Diego on May 13.
Filatov will present a paper co-authored by Larry Hawkins, Calnetix’s Director of Technology for Magnetic Bearings, on the design of a non-contact radial electromagnetic damper and its application in a multi-stage downhole natural gas compressor being developed to boost gas flow from the wells. The paper discusses the capability of this non-contact electromagnetic damper to restrict lateral rotor motions without exerting rotational drags or destabilizing negative stiffnesses.
“The active radial electromagnetic damper has been successfully used in Upwing’s Subsurface Compressor System to stabilize rotodynamic modes,” said Herman Artinian, President and CEO of Upwing Energy. “This technology is enabling us to introduce magnetic bearings into downhole rotating devices for increased product reliability and availability.”
Over 20 years since its inception, IEMDC is the premier forum for the presentation and discussion of new research results and advances in the field of electric machines and drives. IEMDC seeks to address all aspects of design, operation, control, and systems integration of electric machines, electromechanical actuators, and the controls and power electronic drives that implement their applications.
