rcegenerated in the dynamo causes the current of electricity to passfrom a lower to a higher potential in the machine, and from thehigher back to the lower potential in the external circuit; thatis, the dynamo generates electrical pressure which overcomes theresistance or opposition to the current… … Fig. 162.—Holzer Cabot type M dynamo. The design of the base is such that it allows thefield ring or frame to drop down, lowering the center of gravity, which gives increasedstability. The pedestals are bolted directly to the base. Both front and rear pedestals areremovable, so that the armature…
