HOLTZER-CABOT ELFXTRIC CO. ROSTON, MASS, hIGURE 12. Alternating Current Motor=Generators. nU SATISFACTORY and reliable Alternating Current Motor-Gen-Iri erator is necessary when the alternating current is to be used ^— in conjunction with a mechanical or other direct current in-terrupter. We recommend the form here shown as thoroughly reliable andsatisfactory. It transforms the commercial alternating current to 20 volts directcurrent, furnishing the same kind of current to be used in the induc-tion coil as is delivered by the Direct Current Motor-Generator shownon the preceding page. In ordering an Alternating Current Motor-Generator it is neces-sary to specify the voltage and frequency of the alternating current tobe used. Alternating Current Motor = Generators.
