SELF-CONTAINED TRACTION ELECTRIC DRIVE Russian patent published in 1996 - IPC

Abstract RU 2053143 C1

FIELD: transport engineering. SUBSTANCE: electric drive has two traction motors. Armature windings and field windings of motors are connected by switching elements into one series circuit with rectifiers supplied from two armature windings of ac generator. Provision of two circuits, each consisting of series- connected braking resistor and diode connected to sections of above-indicated series circuits, ensures electric braking. Electric drive can be built around contact or noncontact switching elements. EFFECT: enlarged operating capabilities, enhanced reliability. 7 cl, 4 dwg
