DEFINITION

Classification: 318/477

(under subclass 476) Subject matter in which the load on the motor or the armature or primary circuit of the motor is

caused to be increased to a magnitude in excess of or above a predetermined value at the will of an operator or by means which is designated to, and will cause the motor to be overloaded at a time selected by the operator or designer.

(1) Note. For example, an operator may deliberately increase the load on the motor by manually increasing the load actuated by the motor, or by manipulating the motor controls so as to cause the motor to draw an excessive current; or a temporary obstruction may be placed in the path of movement of the motor or device actuated thereby which will cause the motor to exert greater effort with resultant increase in motor current, as a result of which some motor control will be exercised.

SEE OR SEARCH THIS CLASS, SUBCLASS:

469, for motor systems having automatic means for controlling the motor at its limit-of-travel (by means located at the limit-of-travel of the motor or device actuated thereby for overloading the motor) in order to cause the circuit of the motor to be opened or otherwise controlled.
