SEPARATE ELECTRIC DRIVE OF TRAVELER DISPLACEMENT MECHANISM Russian patent published in 2013 - IPC B60L9/16 

FIELD: transport.

SUBSTANCE: invention aims at equalising loads of traveler running gear motor loads. Separate electric drive of traveler displacement mechanism comprises running wheels 1, 7 with reduction gear units 2, 4 driven by induction motors 3, 5. one of running wheels 1 is driven by induction motor with phase rotor 3 while another running wheel is driven by induction squirrel-cage motor 5. Stator winding of the latter is connected to first motor rotor winding via matching transformer 4. Transformation coefficient of the latter equals that of reducing the stator winding to first motor rotor winding.

EFFECT: equalised load of traveler running gear motors, higher efficiency and safety.
