Description:

These electric motors meet IEC standards.

The motors are rated for continuous operating mode S1 from AC network, 50 Hz, 6000 V.

The motors are manufactured with frictionless bearings with one shaft end. Bearing lubrication of electric motors АВ5А-800 is consistent, bearing lubrication of АВ5А 1000 and АВ5А-2000 motors is liquid in oil reservoirs.

Winding insulation of the motor is thermosetting «Monolith-2», it belongs to heat-resistance class “F” by GOST 8865-93, and with temperature usage as class “В”. Temperature excess for motor parts meets GOST 183-74.

The stator winding has six terminals, which go to one terminal box. Phase connection is “star”.  Winding ends are connected in “zero” on one insulator inside the terminal box.

Protection degree of the motor meets IP 54, of the terminal box – IP55.

Constructive mounting arrangement – IM 4011 by GOST 2479-79.

The motor shaft is coupled with the pump shaft by flexible coupling, thus axial efforts should not affect on the motor shaft.

Motors are made with right sense of rotation, if you see from side of the working shaft end.
Cooling method – ICW37A81 GOST 20459-87.

Climatic construction and allocation category is УХЛ4. Electric motors of tropical version TB3 may be manufactured.

The motor designation is decoded as follows:

АВ5А

А – asynchronous
В – vertical
5 – number of series
А – for usage at NPP

ХХХ – Rated power, kW
Д – Designation for voltage 10 kV
Х – Number of poles
ХХХ – Climatic construction
Х – Allocation category
