The motors are designed to drive (directly) the fans in cooling towers and rated for operation from AC network with voltage: AСВO15 – 380V; ВАСВ 17 – 6000V, AСВO5К – 380 V and 380/660 V, and frequency 50Hz.

Description:

Motors AСВO15 and ВАСВ 17.

Operating mode is continuous. Climatic construction: У1.
Stator winding insulation is thermosetting of «Monolith 2» type of heat-resistance class «F».

Motors have constructive mounting arrangement:
AСВO 15 – vertical – IМ8421;
ВАСВ 17 -vertical -IМ8221.
Degree of protection: case and terminal box:
AСВO – blown, with protection degree IP44;

ВАСВ – with water cooling, with protection degree IP44.

Along the shaft these electric motors can be completed with magnetic-liquid sealing, which prevents ingress of moisture, dust, etc. in the bearing assembly.

Motors AСВO5К.

Operating mode is continuous. Climatic construction and installation category – У1.5 by GOST 15150-69.
Electric motors AСВO5К are designed to replace electric motors AСВO15.
Constructive mounting arrangement: IM 9631

Protection degree: the case and terminal box – IP54.
Cooling method: ICA0141 – blown, with self-ventilation.

Motor run is direct, it is realized both at rated voltage and at mains voltage drop during the start up to 0,8 Unom.
Motors have frictionless bearings. Bearing lubrication – consistent grease.
Motors have left and right sense of rotation.

Stator winding insulation is thermosetting of «Monolith 2» type of heat-resistance class «F».
The terminal box has three power clamps and grounding clamps, it enables inlet of the armoured cable with copper or aluminum veins.

Temperature sensors are installed in frontal parts of the winding to control stator temperature.

The motor designation is decoded as follows:

АСВО5К

А – asynchronous
С – special
В – vertical
О – blown
5 – series number
К – made in Novaya Kakhovka
75 – Power of the motor in kW
34 – Number of poles
У1.5 – Type of climatic version and installation category by GOST 15150
