INDUCTION DEVICES WITH DISTRIBUTED AIR GAPS

摘要

A distributed air gap material for an induction device in power systems for minimizing fringe losses, mechanical losses, vibration and noise in the core. The distributed air gap material occupies a selected portion of the core and is formed of a finely divided magnetic material in a matrix of a dielectric material. The air gap material has a zone of transition in which the magnetic permeability values vary within the air gap material.
