TRACTION VEHICLE ELECTRIC POWER TRANSMISSION GEAR Russian patent published in 2007 - IPC H02P5/00 B60L11/08 

FIELD: electrical equipment for electrified traction consists.

SUBSTANCE: proposed device has synchronous traction generator set in rotary motion by means of heat-engine shaft, first electric-power transmission gear control unit (driver's controller), first uncontrolled rectifier, off-line current inverter, traction slip-ring induction motor, current sensor of first uncontrolled rectifier, voltage sensor of third uncontrolled rectifier, traction synchronous generator excitation unit, third control unit, and microprocessor controller; traction induction motor shaft is coupled with axles of traction-vehicle moving wheels; two three-phase rotor windings of traction induction motor are shifted apart through 30 el. degrees and connected by means of series-interconnected second and third rectifiers to first uncontrolled rectifier; synchronous traction generator excitation unit is connected to first output of microprocessor controller by means of second control unit.

EFFECT: reduced cost, size, mass, and power requirement for cooling power transmission, enhanced reliability and efficiency of device.
