Description:

Explanation of designation P2Sh-ХХХ-ХХХ-ХКХ4:
P2Sh – designation of motor series
XXX – height of rotation axis, mm (630, 800, 1000)
XX – number of armature diameter (21,25) (armature diameter, mm, accordingly 2150, 3400)
X – number of armature core length (3.4,5,6)
X – quantity of brushes on each bracket (4,7)
K – designed on rolling bearings (in motors size 21 of cantiliver version letter “K’ is missing)
X4 – climatic version (UHL or 0) and category of location.

The motors are enclosed machines with closed horizontal design with induced ventilation from separate ventilator
with open or closed circuit employing air coolers.
Thermal endurance class of insulation of all armature circuit windings – “H”, that of field winding – “F”.
Insulation of the armature circuit windings to the frame has been designed for 1500 V and that of the field
winding – for 1000 V.

Tolerable current overloads:
– operational not more than 15 s – 2,0 I nom,
– breaking – 2,25 I nom. I nom means rated current value.

The motors are intended for use in temperate climate and withstand continuous current loads 1,15 I nom under
permissible overheatings of class “F”.

Rated voltage of motors – 930 V. Separate excitation – 220 or 110 V.

Main rated voltage – 220 V.

For power transfer to rated voltage 110 V the motor has an outlet for four finishes of field winding.
Used in the motors are rolling bearings lubricated by consistent (fat) grease to facilitate operation.
