On the coefficients of core loss formulas for electrical machines

- Summary
- Metrics

Abstract

In this paper the behavior of core loss coefficients is studied using a new method of core loss separation. This method eliminates the assumption of uniform magnetic field distribution in a material especially at high frequencies. With this separation method, the hysteresis and eddy current coefficients are calculated using the original Steinmetz equation and its derivative. The calculated loss from the coefficients of the two formulas is then compared to the loss from the separation. Results and conclusions are also presented.
