TERS 1,461 With this simple machine the following principles can be demon-strated: 1. If the coil be rotated, alternating currents can be taken fiom thecollector rings and it is called an alternator. 2. By connecting up the wires from the commutator segments, adirect current will flow in the… … Flu. 2.036.—Diagram of three phase rotary converter. In this type, the winding is tapped atthree points 120° distant from each other, and leads connected with the correspondingcommutator segments. 4. If a direct current be sent in the armature coil through the com-mutator, the coil will begin to…
