.~ By auxiliary electric generator or by magnetic attraction or repulsion devices
DEFINITION
Classification: 318/382
(under subclass 362) Subject matter in which the braking means comprise (1) an electric generator connected to be driven by the motor for the purpose of braking the motor or (2) Magnetic-Flux-producing means which operate directly through the agency of the flux, per se, to oppose, by magnetic repulsion or by magnetic attraction, the tendency of the motor to continue in motion, if in motion, or to move if not in motion.
(1) Note. Magnetic operators for other types of brakes (e.g., friction, fluid, etc.) are not included herein.
SEE OR SEARCH THIS CLASS, SUBCLASS:
375, for systems wherein the motor itself is converted into an electric generator to operate as a braking means.

388, Electricity: Motor Control Systems, art collection 931 for single motor running-speed control systems wherein a generator is driven by the motor, while the motor is electrically energized, which generator acts as a retarding or braking means to affect the running-speed of the motor.
