ELECTRIC BRAKING APPARATUS FOR ALTERNATING CURRENT MOTORS

摘要

ELECTRIC BRAKING APPARATUS FOR ALTERNATING CURRENT ELECTRIC MOTORS An electric braking circuit for a.c. motors is disclosed. When the a.c. power is cut off from the motor windings, at the same time a switch is thrown to connect the a.c. source of power to the same windings via a rectifier and a smoothing circuit, to thereby bring the motor to an immediate smooth stop.
