  • AC Induction motor braking system
    Patent number: 4374352
    Abstract: A three-terminal network which electrically senses the time at which the voltage applied to an AC induction motor is removed and concurrently therewith utilizes energy which was previously stored in a capacitor to effect eddy-current braking of the AC induction motor is disclosed.The disclosed system may be utilized to quickly, i.e., within two revolutions, brake a two-terminal shaded-pole induction motor, or a two-terminal unidirectional split-phase motor, or a three-terminal bidirectional split-phase motor.
