Abstract :
The application of dimensional analysis to measurements made on cold rolled electrical steels yields empirical equations relating ac core losses to hysteresis losses and other factors. As frequency increases from low values, three different patterns of loss variation occur because of increasing skin effect. Loss measurements indicate that samples with lower hysteresis losses and thinner gauges have relatively larger magnetic domains. The hysteresis losses of well-annealed samples are found to depend primarily on grain sizes and orientations. The steels investigated have only incidental amounts of grain orientation.
