(a) Estimate the hysteresis loss at 60 Hz for a toroidal (doughnut-shaped) core of 300-mm mean diameter and a square cross section of 50mmby 50mm. The symmetrical hysteresis loop for the electric sheet steel (of which the torus is made) is given in Figure.
(b) Now suppose that all the linear dimensions of the core are doubled. How will the hysteresis loss differ?
(c) Next, suppose that the torus (which was originally laminated for reducing the eddy- current losses) is redesigned so that it has half the original lamination thickness. Assume the stacking factor to be unity in both cases. What would be the effect of such a change in design on the hysteresis loss?
(d) Suppose that the toroidal core of part (a) is to be used on 50-Hz supply. Estimate the change in hysteresis loss if no other conditions of operation are changed.
