DCIB-100 DC INJECTION BRAKE

In certain applications involving polyphase induction motors, it is sometimes desirable to have available a means of braking the motors speed (e.g., an overhauling load). Unlike the DC motor in which the armature is disconnected from the line and connected across a resistor as a generator (as with the Hampden Model DB-100 Dynamic Braking Demonstrator), there is no way to disconnect the primary armature of an induction motor and still maintain excitation of the rotor secondary in the same manner. Braking can still be accomplished, however, if the primary excitation is removed and if the stator is excited with direct current instead.
