ABSTRACT:
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.
