| Zusammenfassung: | A speed controller for a direct‐current motor has been constructed, operating on the principle of the differential gear. It has been found that the speed of the direct‐current motor is controlled by this arrangement with about the same degree of accuracy as the regulation of the frequency of the controlled‐frequency a.c. power line which serves as a standard. |
