DEFINITION

Classification: 318/469

(under subclass 468) Subject matter in which means are provided for overloading the motor automatically when the limit-of-travel has been attained.

(1) Note. For example, when the motor or a device actuated

thereby reaches its limit-of-travel it may contact a compression spring or an abutment device placed permanently or temporarily or momentarily in its path thereby placing increased load on the motor resulting in increased armature circuit current which may be availed of to effect the particular motor control desired.
