Synchronous electric motors of СДKП 4 type are used to drive compressors, and they are designed for operation in continuous mode in explosive zones of premises of all classes, except for outdoor installations. The motors are rated for operation in continuous mode from AC network, 50 Hz, with voltage 6000 V or 10000 V.

Description:

Climatic version – УХЛ4 by GOST 15150.

Degree of protection – IP44. Motors have explosion-proof level of explosion protection (1), with explosion protection «filling the casing under overpressure» (р) by GOST 22782.4, (рх) by GOST R 51330.3, group of electric equipment II, thermal class Т5 by GOST 22782.0, GOST R 51330.0. Explosion protection marking is 1ExpIIТ5 by GOST 12.2.020 for delivery to Ukraine and 1ExpxIIТ5Х by GOST R 51330.3 for delivery to Russia.

Construction version – IM 5710 (console) – for electric motors СДKП4-16,17,18; IM 7125 (flange) – for electric motors СДKП4-17,18,19.

The thyristor exciters with control and self-regulating system for exciting current energize the motors.
Motor start is asynchronous, direct, at full network voltage with discharging resistance going into the circuit of field winding.
Insulation of stator winding belongs to heat-resistance class not lower than “F”. Stator winding is connected in “star” and has six terminals brought in the terminal box.
