DEFINITION

Classification: 318/279

(under subclass 278) Subject matter in which the automatic control means comprises means responsive to an electrical condition for stopping the motor which means, however, has been rendered inoperative or is otherwise less responsive to the electrical condition during the acceleration period of the motor.

(1) Note. Characteristic of the subject matter of this subclass are those acceleration systems in which overload or excessive-current cut-outs are provided for automatically stopping the motor by opening the armature or primary circuit thereof when the armature or primary current exceeds a predetermined value during the full-speed operation of the motor but wherein means are provided for preventing or reducing the tendency of such cut-out to operate during the acceleration period of such motor.
