    摘要: For use with a phase synchronizing circuit which synchronizes an A-C motor at the receiving end of a communication link with one at the transmitting end thereof by repeatedly applying to the main coils of the receiving end motor, reduced frequency signals having a lower frequency than the rated frequency thereof to thereby reduce the phase deviation between the receiving and transmitting end motors, the improvement of a braking circuit for enhancing the speed and accuracy of the phase synchronizing circuit, the braking circuit including means for applying a direct-current voltage to the main coils of the receiving end motor prior to or in lieu of each of the reduced frequency signals.
