Primary core and solid secondary eddy-current losses are determined in the electromagnetic topology of a tubular linear induction motor (TLIM). The nonlinear B-H characteristic, hysteresis and skin effect are considered in deriving formulas for eddy-current losses. A means to reduce these losses in...
A new analytical method to calculate eddy-current losses in the ferromagnetic tube of pipe- type cables has been developed. A uniform current distribution in the cylindrical cable cores was assumed. The magnetization characteristic of the pipe material was assumed linear and hysteresis losses were neg...

In this paper formulas are developed, on the basis of simple physical conceptions, for the calculation of eddy currents in solid and laminated iron, which, as the experiments presented show, enable the losses caused by eddy currents to be predicted with surprising accuracy. A simple formula for...

Eddy currents are generated when a conductor undergoes varying magnetic fields. As these eddy currents are ideal and not functional, these impose a loss in the magnetic substance and are known as Eddy Current Losses. In the same way as hysteresis losses, eddy current losses also enhance the mag...
