connected to atwo-phase circuit, and let curves A and B, Fig. 451, representthe voltage applied to the windings, consequently the currentflowing in them. At the instant a on the curves, Fig. 451, itwill be seen that the voltage in phase A is at a maximumvalue, while that in B is at zero,… … Fig. 452 <^Fig. 452.—Schematic diagram of two-phase motor.Fig. 453.—Same as Fig. 452, but 45 degrees later. indicated. Since the current is at a maximum, the magneticfield will also be at a maximum value and will divide at thecenter of the N poles, pass into the rotor core back into the Spoles,…
