Kernverlust
Kernverlust refers to the energy that is lost as heat in the magnetic core of electrical devices such as transformers, inductors or electric motors when the core is exposed to alternating magnetic fields. It is composed mainly of two contributions: hysteresis loss and eddy current loss.
Hysteresis loss arises from the repeated realignment of magnetic domains as the magnetic flux density changes
Material and design implications: To minimize Kernverlust, engineers select soft magnetic materials with favorable hysteresis properties,
Measurement and standards: Core loss is specified for given drive conditions and is typically expressed in
Applications: Core loss is a key efficiency parameter in power transformers, inductors, reactors and electric machines,
