Iron losses in direct-current machines
Proceedings of the American Institute of Electrical Engineers, 1916The term iron loss, as used in connection with rotating machinery, is shown to cover a large number of losses, some of which actually do not lie in the iron itself. The term core loss should be used except when the losses are actually located in the iron itself.

Iron Deficiency and Hearing Loss
ORL, 2010Cochlear changes were studied in 141 growing rats raised on a basic iron-deficient diet for 7–100 days; 130 rats served as normal or chronic anemia controls. Electrophysiological findings showed that the incidence of an auditory threshold elevation of more than 15 dB was 31.85 % in the iron-deficient rats, but it was unchanged in all the control ...

Since inductors used in power electronics circuits are magnetized under completely different conditions from sinusoidal alternating voltage/current, the manner of occurrence of iron loss is often greatly different. In this chapter, we clarify the difference between the magnetizing modes of the transformer and inductor used in the power electronics ...

A mechanical method of iron loss measurement in a rotational field was developed and, using this method, the mechanism of iron losses of motor cores was investigated. Iron losses in rotational fields of angular velocity ω(rad/s) induce torque T (Nm) in specimens, and the total losses are calculated from ωT.

ABSTRACT To the Editor:— In your editorial "Recent Studies of Iron" (page 904, March 25, 1950) you called attention to large losses of iron in the sweat as reported by Mitchell and Hamilton (J. Biol. Chem.178: 345, 1949). We have recently studied the iron content of sweat obtained from 25 normal persons (Adams, Leslie and Levin: Dermal Loss of Iron, to

In Section I the iron loss in six d.c. machines with undistorted flux has been analysed to determine:? (a) The effect of high flux-density upon the hysteresis loss. (b) The hysteresis and eddy-current exponents over a wide range of flux density. (c) The ranges of frequency and of flux density over which the total iron loss can be represented by an ...
