Patent ID: 10319505

Abstract:
The Electro-Magnetic Flux Valve (EMFV) is an electrically actuated permanent magnet field flux shunt comprised of a low reluctance ferromagnetic core, surrounding a permanent magnet, with at least two imbedded control element sections by which the permeance of the core can be reduced. When placed within an external closed magnetic circuit, the EMFV core, at quiescence, acts as a keeper to the magnetic flux of the magnet. When electrically activated, the EMFV core permeance is reduced and the permanent magnet flux is released to energize the external magnetic circuit. When the control signal is removed the EMFV core again becomes highly permeable and constrains the permanent magnet flux thus deenergizing the external magnetic circuit. The EMFV is intended to be an integral part of a Magnetic Power Converter.
