DEFINITION

Classification: 318/742

Electromagnetic brakes:

(under subclass 741) Subject matter wherein the braking action is a result of electromagnetic force.

(1) Note. The force of this subclass type may be within the motor or external to the motor and physically transmitted to it.

(2) Note. Electromagnetic brakes of this subclass type include, for example, eddy current brakes.
