On the coefficients of core loss formulas for electrical machines

IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012
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 ...

Ultra-low Loss Silica Core Fiber

Optical Fiber Communication Conference, 2018
We review recent advances in optical fiber technologies that realize ultra-low losses as low as 0.142 dB/km including pure-silica core and reduction of microscopic density fluctuation.

Squirrel-cage induction-motor core losses

Journal of the A.I.E.E., 1925
An experimental method is presented for segregating the various no-load losses of a squirrel-cage induction motor. It is shown that for insulated rotor bars the losses consist principally of stator fundamental-frequency losses, rotor surface losses and eddy-current losses in the rotor bars due to radial and tangential slot-leakage fluxes in the rotor ...
