TECHNOLOGIES

POWERFUL SCIENTIFIC AND PRODUCTION BASE, INCLUDING THE COMPLETE CYCLE OF ELECTRIC VEHICLE CREATION FROM DESIGN STAGE TO MASS PRODUCTION.

MANY TECHNOLOGIES, MODERN EQUIPMENT AND DIAGNOSTIC DEVICES ARE USED TO ACHIEVE THE BEST RESULTS IN PRODUCTION:

  • fabrication operation of free-form shapes on the laser complex;
  • casting of non-ferrous metal parts by rotational casting, as well as on high-pressure casting vehicle;
  • using modern high-performance metalworking equipment;
  • testing of traction motors by reciprocal load;
  • roller ultrasonic inspection;
  • electromagnetic inspection;
  • removal of armature winding by gyroscopic method;
  • gas-pressure welding of electric machine shafts;
  • dynamical commutator rectifier forming;
  • compound of the armature winding with the commutator rectifier by the welding procedure of non-consumable electrode in the inert-gas blanket;
  • vacuum pressure impregnation armature;
  • dynamic balancing of traction electric motor with computerized process control;
  • semi-automatic coil wrap by "edge" strip taping;
  • coil-winding short circuit checking;
  • traction electric motor shaking table testing for increased vibration;
  • determination of specific losses in the stator steel;
  • measurement of interaxial spaces, control of the ratio of the throat housings of traction motors in the performance of fittings and assembly works;
  • stripping of the centre of the wheel and elastic gear from the axis of the wheelset;
  • high-frequency heating of the elastic gear and the wheel centre;
  • heating of bandages of wheel centres;
  • small gear press from the shaft of traction electric motor blast pipe;
  • shrink-ring rolling;
  • restoration or replacement of gear, wheel centre, bracing cage;
  • registering of diagrams insertion and strike shift checking;
  • wheel-motor block trimming;
  • crack detection;
  • wheel-motor block running test in complete;
  • painting, reconstruction.
