Question

EA Fig. 2.32 shows a slot con- Iron tining z, conductors and each conductor carries a current of i amperes. The retic circuit is assumed to have infinite perme- ability. iron part of the mag- h2 (a) Find the variation of the flux density in the part of the slot (i) above the conductor portion and (ii) occupied by the conductor. Slot leakage ! flux (b) Find an expression for the leakage flux above the conductor portion. Current out (c) Find the electromagnetic force fe, created of paper by the slot leakage flux present above the conduc- tor portion Fig. 2.32. Slot leakage flux, Example 2.17. (d) For i = 2 (1000) sin 314t, find the direction and magnitude of magnetic force found in part (c). There are two conductors in the slot, embedded length is 1 metre and slot width is 5 cm.
