ABSTRACT:
A direct current motor includes a chopper in series with the field coil of the motor to regulate the current flowing through the armature of the motor during electrical braking when the motor functions as a generator to produce current. In addition, a shunting device is connected to the field coil to regulate the current flowing through the coil so that it is maintained at a value less than the armature current.
