2980. Moore, E. S. W., and Boyden, T. L. Feb. 7. Motors, controlling. -The speed variation of direct-current motors is controlled by exciting the field by means of an exciter driven by the motor. As shown in the Figure, the motor M drives the dynamo D, its field MC being in series with the field DC and armature of the generator D. This arrangement is particularly applicable to boosters.
