Abstract

When using a powder magnetic core fabricated from iron powder coated with an insulator in motors, reactors, etc., the effect of stress on its magnetic properties should be considered. In this paper, a system for measuring the magnetic properties of a powder magnetic core under compressive stress was developed and applied to a powder magnetic core, namely a high-density magnetic composite (HDMC). It is illustrated that the iron loss is increased by about 20% when a compressive stress of 100 MPa was applied
