In article electromechanical ratios of system of the multi-engine adjustable electric drive of water lifting pump installations are considered. It is shown that in relation to the system of the multi-engine electric drive with electric communication on a rotor chain and with the general inverter conducted by network the equivalent circuit provided to a chain of the straightened currents of rotors of asynchronous engines is created. On the basis of the equivalent circuit the system of the equations of electric balance for in common working driving electric motors of pump units as a part of water lifting pump installation which at the corresponding mathematical transformations allows to receive the main electromechanical ratios of the considered system of the multi-engine electric drive is received.
