Iron losses in turbogenerator teeth
Journal of Applied Physics, 1982The flux density was measured in a typical tooth of a 500-MV A synchronous generator. Peak flux densities of 14.3, 16.9, and 21.2 kG were observed in an open circuit test at 80%, 100%, and 125% of rated voltage. The search coil voltage waveforms were rich in odd harmonics tending toward a square wave.

Iron Loss and Iron Requirement
1983Measurement of iron loss is technically difficult. Chemical iron balances require meticulous technique to avoid contamination, and they do not allow the differentiation between nonabsorbed iron and iron excreted through the gastrointestinal tract. Isotope techniques require knowledge of the distribution of the radioiron within the organism and the ...

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.

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 ...

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

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.
