Description:

Explanation of designation:
P2-ХХХ-ХХХ-ХСХХ:
P2 – designation of motors series
XXX – height of rotation axis (630, 800, 1000 mm)
XX – number of armature diameter – 21, 22, 23, 24, 25 (armature diameter in mm is produced accordingly
2150,2500,2850,3100,3400)
X – number of length of armature core (3, 5, 6, 7, 8)
X – quantity of brushes on each bracket (8, 14)
C – design on plain bearings
X – climatic version (UHL, O, T)
X – location category (4, 3)

For design Y3 minimum temperature of ambient air is minus 10°C.

The motors are enclosed machines with closed or open circuit induced ventilation employing air coolers.

Tolerable 15-s operation overloads:
– at rated rotation frequency – 2,25 I nom;
– at maximum rotation frequency – 1,8 I nom.
Breaking overloads:
– at rated rotation frequency – 2,75 I nom;
– at maximum rotation frequency – 2,0 I nom. I nom means rated current value.

When operating under the above-specified overloads the maximum rate of current changes in armature circuit is up to
100 Inom/s.
The motors that operate in temperate climate withstand continuous current loads 1,15 Inom at temperature rises for class
“F” insulation.

Rated armature voltage – 930 V.

Rated voltage of separate motor excitation – 220 V.

For power transfer to 110 V the motor has an outlet of four finishes of field winding.

The motor is supplied from static and rotatable voltage converters.

Winding insulation of class “F’ is of polyimide. Insulation of windings of armature circuit relatively the motor frame is
designed for 1500 V, field winding – 1000 V.

Motor reverse is performed by changing of current direction in the armature circuit.

Tolerable is three-fold excitation forcing.
