Calculation of the reaction force of high-coercivity permanent magnets in half-couplings of a magnetic clutch with dismantling of a sealed vertical pump

Abstract

An expression is provided for determining the reaction force (separation force) of high-coercivity permanent magnets made of rare-earth element alloys during separation (axial movement of the outer with respect to the inner half-coupling) of a half-coupling of a clutch, used in vertically sealed pumps.
