Device for synchronizing two asynchronous rotary field motors, the output of said motors being via reduction gears connected to the movable parts of synchronizers of for instance the selsyn type, said synchronizers being connected to generate a correction signal dependent on direction and value of a positional difference between the said movable parts, said motors being controlled by a frequency converter the output frequency of which is controlled by an electrical input, at least one of said inputs being combined with said correction signal, R.C.-circuits controlling the time function of the said electrical inputs. |
