374
.~.~ Energy flow interrupted when motor stops
DEFINITION
Classification: 318/374
(under subclass 373) Subject matter in which means are provided for interrupting the flow of energy to the motor substantially at the time that the motor speed is reduced to zero.
(1) Note. The termination of the flow of electric energy to an electric motor as the motor speed substantially reaches zero is considered part of the operation of braking and not another motor control operation, such as automatic stopping of the motor; and hence, such systems are not considered combined braking and automatic stopping systems but rather merely a braking system, per se.
SEE OR SEARCH THIS CLASS, SUBCLASS:
461, for motor systems having automatic control means for merely stopping the motor when the speed of the motor falls below a predetermined value.
519, for motor systems having an armature or primary circuit making and/or braking device for stopping the motor.
