An illustration from Small motors, transformers, electromagnets; a practical presentation of design and construction data for small motors, small low- and high-tension transformers, electromagnets, and induction coils, 1920, leaf 186 — ines of force is concerned, a corebuilt up of plates as shown in Fig. 18 so as to break jointsconstitutes a fairly good magnetic circuit and is very easy notonly to construct but to take apartwhenever desired. Assumed Data for Eddy=CurrentLoss. The equations for the eddy-cur-rent loss and the… … Fig. 18. BuUt-Up Core ofTransformer The quantities are assumed to be as follows: b equals 15 1000 inch. or 15 mils, and b^ equals 225; / equals 60 cycles, and /^ equals3600; and M equals 3000 gausses, and M^ equals 9,000,000.
