Vertical asynchronous electric motors of ВАН-5 type with squirrel-cage rotor are used to drive vertical hydraulic pumps for national economy needs, and electric motors of ВАН-5A type – for NPP pumps.

Description:

These electric motors meet IEC standards.

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

Climatic construction – У, Т, allocation category – 3 by GOST 15150-69 and GOST 15543.1-89.

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.

Constructive mounting arrangement – IM8425 by GOST 2479-79.

During operation motors take weight loads from rotating pump parts and water reaction. In motors of 118, 143 gabarits the flange with the shaft are made separately, in motor of 173, 215 gabarits the flange with the shaft are made as an integral item.

Motors are made with right sense of rotation, if you see from side of the working shaft end.

Protection degree of the motor meets IP23, of the terminal box – IP55 by GOST 17494-87.

Cooling method – ICА01 GOST 20459-87.

The motor designation is decoded as follows:

ВАН5А-Х-ХКЭМХЗ

В – vertical
А – asynchronous
Н – to drive pumps
5 – number of series
А – for NPP

Х – Motor power, kW
Х – Number of poles
К – With contact rings
Э – Version for installing the electromechanical  drive to turn pump blades
М – With coolers for sea water
Х – Climatic construction (У, Т)
З – Allocation category
