DEFINITION

Classification: 318/362

(under the class definition) Subject matter in which means are provided for braking the motor.

(1) Note. For definition of motor braking control, see Class Definition, Glossary, "Motor Load Control"

(2) Note. Whenever the motor is braked by "plugging" (i.e., by power reversal while motor is running) and energization is continued so that motor operates in the reverse direction, classification is in combination reversing and braking. See subclass 261.

SEE OR SEARCH THIS CLASS, SUBCLASS:

86, and the subclasses specified in the Notes thereto, for plural motor systems having braking control.

159, for motor systems where the motor has means (e.g., springs) for biassing the motor against rotation. 161, for motor systems where the motor has a fly-wheel or other massive rotary member for retarding an increase in speed of the motor.

273, and the subclasses specified in the Notes thereto, for motor systems having braking control and another motor-operation control.

703, for braking means in synchronous motor systems.

757, and the subclasses specified in the Notes thereto, for braking means in induction motor systems.
