Hanna Curves For Silicon Steel

0 4 8 12 16 20 24 ence in inductance between Y and Y' is 4 per cent, for a difference in air gap of 33 per cent. An example will show how easy it is to make a reactor according to this method. Example. Assume a stack of silicon-steel laminations having a cross section Y in. by Ji in., and with iron filling 92 per cent of the space. The length of the flux path l0 in this core is in. It is desired to know how many turns of wire and what air gap are necessary to produce 70 henrys when 20 ma direct...
