ad of the currentbeing distributed as indicated in Fig. 465, the actual condi-tions approach those of Fig. 466. Here it is seen that, owingto the rotor current lagging behind the voltage, the rotors Nand S poles come considerably back under the stators N andS poles respectively. Consequently, the… … j-^iG. 465.—Magnetic Held set up by the rotor when the current is in step with voltage. The Induction Generator.—Assume that power is appliedto the rotor.
