F. Mcquade et al., CORRELATION OF INTERNAL-STRESS AND POWER LOSS WITH DOMAIN MOTION IN STRIP WOUND MAGNETIC CORES, Journal of magnetism and magnetic materials, 133(1-3), 1994, pp. 136-139
An investigation into the correlation between stress induced by adhesi
ve bonding in wound cores and the effect on the domain structure is pr
esented. Increases in power loss of up to 70% at a flux density of 1.7
T, 50 Hz are found in toroids after the application of adhesive. Inve
stigations on dynamic domain motion showed that the amount of wall bow
ing was almost doubled at an overall flux density of 1.0 T, 50 Hz unde
r the influence of the stress induced by the adhesive.
