d current is kept as small as pos-sible by the use of a small air gap clearance between the statorand rotor; a 50-h.p., 900-r.p.m. induction motor will have a rotordiameter of 20 in. (51 cm.) and an air gap clearance of 0.03in. (0.075 cm.) and, in spite of this small air gap, the magnetizingcurrent… … Fig. 344.—No-load Fig. 345.—Ideal. Fig. 346.—Actual,vector diagram.
