he balance coil taps. One coil willoperate the system, but two coils, giving four points spaced 90 electricaldegrees apart, give better distribution of the current to the armaturewinding and better regulation of the voltage. Boosters.—A booster may be defined as, a dynamo insertedin a circuit at a… … Fig. 805.—Crocker Wheeler motor-dynamo set. There are numerous cases where such acomisination is useful for furnishing a circuit with a voltage different from that of the mainplant or with a voltage that can be varied independently. For storage battery chargingand electrolvtic work, where constant…
