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 ...

In this chapter, methods to calculate iron losses of motors by using electromagnetic field analysis are presented. First, the components of iron loss, i.e., hysteresis loss, eddy current loss, and excess loss, are explained. Next, the iron loss calculation methods that consider the effects of nonlinear characteristics of the core materials, mechanical ...

Tritium loss in iron meteorites
Earth and Planetary Science Letters, 1967Abstract The concentrations of cosmic ray produced3He in the medium octahedrites Ruff's Mountain and Roebourne are too low as compared to the concentrations of other spallogenic nuclear species. A number of arguments is compiled which indicate that the3He anomaly in these octahedrites and in some hexahedrites, as well as the low spallogenic tritium ...

Magnetic materials and iron losses
2008Most electrical machines and instruments rely on magnetism for their operation, and in many cases ferromagnetic materials are used, since the magnetic flux produced is thereby increased. This chapter considers some of the properties of these materials and indicates that in many cases the application of magnetic materials brings with it problems which ...
