DEFINITION

Classification: 318/367

(under subclass 366) Subject matter in which the sensing means is responsive to the magnitude or the rate-of-change of the magnitude of the electric current in the armature or primary circuit of the motor being braked.

(1) Note. Where the sensing means comprises a relay which is responsive to the terminal voltage of the electric motor (i.e., connected to shunt to the motor armature circuit) such sensing means is treated as being responsive to the terminal or c.e.m.f. voltage of the motor and not to the armature current thereof, and is classified in subclass 368.

368, see (1) Note above.

474, and the subclasses specified in the Notes thereto, for other motor control systems responsive to the armature or primary current of the motor being controlled.
