DEFINITION

Classification: 322/91

(under subclass 89) Subject matter wherein the generator is controlled by short circuiting the armature winding or a portion thereof.

SEE OR SEARCH THIS CLASS, SUBCLASS:

47, for generator control systems under subclass 44 where the generator is an induction generator.

53, for the subject matter where the generator is provided with an odd number of brushes (i.e., has an auxiliary brush) and the generator control means includes an armature winding or a portion thereof connected to a short circuit between the odd or auxiliary brush and one of the load brushes.

95+, for generator control by shunting the armature winding through an impedance. Subclass 91 differs from subclass 95 in that in subclass 95 the armature is shunted through a resistance and in this subclass (91) the shunt connection has negligible impedance. See subclass 98 where the shunt circuit contains a resistance.

SEE OR SEARCH CLASS 307, Electrical Transmission or Interconnection Systems,

100, for systems including means for shunting or short circuiting the same.

310, Electrical Generator or Motor Structure,

177, for dynamoelectric machines having a short circuited winding or conductor.

318, Electricity: Motive Power Systems,

379+, for motor braking systems having armature short circuiting and subclass 501 for motor armature circuit control by shunting armature in whole or in part.

320, Electricity: Battery or Capacitor Charging or Discharging, appropriate subclasses, particularly

123, for a battery or capacitor charging or discharging system including a generator.
