The motor thus constructed exhibits too, abetter regulationof current from no load to load, and there isless difference between the apparent and real energy expendedin running The it. true synchronous speed of this form of motoris that of the generator when both are alike that is to say,ifthe number of the coils on the armature and on the field is a?,themotor will run normally at the same speed as a generator drivingUv^-^Mfa^Lum'Fms. 45, 46 and 47.it if the number of field magnets or poles of the same be also or.Fig. 43 shows a somewhat modified arrangement of circuits.There is in this case but one armature coil the E, winding ofwhich maintains effects corresponding to the resultant poles producedby the two field-circuits.Fig. 44 represents a disposition in which both armature andfield are wound with two sets of coils, all in multiple arc to theline or main circuit. The armature coils are wound to correspondwith the field-coils with respect to their self-induction. Amodification of this plan is shown in Fig. 45 that is to say, the
