see page 288. The rotor bars, however, are also cutting the field <f>y, and,since this field is moving in a direction opposite to that of therotor, the frequency of the resulting rotor current Iy is almostequal to 2/. This frequency is high, and the current Iy lags bya large angle; so that… … Fig. 364. Fig. 365. Figs. 364 and 365.—Single-phase series motor. machine runs as if it had only one field 4>x. The characteristicswith respect to slip, efficiency and power factor are thereforesimilar to those of a polyphase induction motor. 340. Single-phase Series Motor.—This machine is wound…
