FIELD: engines and pumps.
SUBSTANCE: invention relates to excavator electrical drives and allows increasing the service life of traction motors. The transfer station electrical drive is designed to provide for transfer of excavators and drilling machines in open pits with the power supply cable disconnected from the supply circuit. The proposed device is a separate electrical drive per every traction motor configured as a "generator-motor" assembly controlled by the PPD-1.5V-type power magnetic amplifier.
EFFECT: longer life of the motor.
