DEVICE FOR UNIFORM LOAD-CURRENT DIVISION AMONG INDEPENDENTLY EXCITED OR SHUNT-WOUND DC MACHINES Russian patent published in 1997 - IPC

FIELD: electrical engineering; paralleling independently excited or shunt-wound DC machines. SUBSTANCE: armature circuits of various parallel-running DC machines set up of armature windings and commutating windings connected to them on side of like- polarity brushes are interconnected by equalizing wires; points of connection of these wires correspond to those of connection of armature and commutating windings. EFFECT: improved uniformity of load sharing among parallel-running DC machines operating as generators and as motors due to introduction of equalizing wires on side of connection of commutation and armature windings using effect of switching armature reaction. 1 dwg
