Asynchronous electric motors with squirrel cage rotor of АОДA type are designed for continuous operating mode S1 from AC network, 50 Hz, to work in structure of pump devices delivered to NPP.
The motors meet the IEC requirements.
The motors are manufactured for voltage 6000V and 10000V.
The motors are produced with frictionless bearings, with one shaft end. Bearing greasing is liquid independent with build-in oil coolers. Outlet ends are removed in the terminal box.
Degree of protection for the motors – IP54, for the terminal box – IP55.
The motors are cooled by self-ventilation. Cooling method – ICW37А71 by GOST 20459. Heated air is cooled by one horizontal air cooler fixed above on the motor housing.
Winding insulation of motors is thermosetting of “Monolith – 2” type with class of thermal classification «F» by GOST 8865, which is used by class «В».
The motor designation is decoded as follows:
АОДА – asynchronous blown motor for NPP
5 – series number.
ХХХ – Rated power, kW
Х – Voltage of the motor, kV
2 – Number of poles
ХХХ – Climatic construction
Х – Allocation category
