s. The A. C. dynamo has no commutator andthe armature can in addition be made the stationary part. TheA. C. induction motor (§ 710) also shares in the advantages ofhigh insulation as well as efficiency and simplicity. 696. Two Phase and ThreePhase A. C. Dynamos. Thealternating current dynamo… … Fig. 464. 6o6 ELECTROMAGNETIC INDUCTION. are the two and three phase systems. The currents are gene-rated in coils placed at different angles on the armature. Thus ina two phase machine, there are two sets of armature coils, thefirst set cutting the magnetic field at a maximum rate, when the…
