FIELD: ventilation.
SUBSTANCE: fan system comprises first and second stage rotors that are linked to the driving gear from the independent asynchronous power motors. The first stage rotor shaft is linked to the rotor of the phase-wound rotor asynchronous motor, and the second stage rotor shaft is linked to the rotor of the squirrel-cage asynchronous motor, and the primary winding of the squirrel-cage asynchronous motor is plugged into the secondary winding of the phase-wound rotor asynchronous motor via impedance corrector.
EFFECT: efficiency upgrading when direct and reverse working.
