IE2 Motor

STANDARD RATINGS :

2 pole 0.18-315Kw
4 pole 0.12-315Kw
6 pole 0.18-250Kw
8 pole 0.18-200Kw

EFFICIENCY :

Confirm to IE2 Level & are marked.

POWER SUPPLY :

For greater application flexibility and increase safety margin our motors are suitable for 415V +/-10%, 50Hz+/5%, combined variation allowed +/10%

AMBIENT TEMPERATURE

-15 to 50 degree C is standard.

SERVICE FACTOR :

These motors have a 1.00 S.F. at 50Hz, typical for IEC motors, Duty class S1.

CONSTRUCTION :

The rugged cast iron construction of the frame, endshields, integral feet and flanges absorbs shock and reduce motor vibration to provide a low-maintenance motor life.

TERMINAL BOX :

The terminal box is of cast iron construction and is available on Top.

STATOR WINDING & INSULATION:

The stator core is built up from low loss, high permeability, silicon steel for increased efficiency. It features a class F insulation system with design for class B maximum temprature rise.

ROTOR :

The rotor is built with the same high quality lamination steel, die cast with high conductivity aluminum, shrunk fit on to a high strength carbon-steel shaft. The rotor assembly is dynamically balanced to provide low noise and smooth, vibration-free operation for long trouble free life.

BEARINGS :

All motors use 100,000 hours direct coupled/25,000 hours belted, anti-friction, deep-grooved ball Bearings 160 frame & above of 63 series, on drive, tight fit in.

COOLING METHOD:

IC 411 bi directional cooling fan.

CONNECTION:

Star-connection for up to 3Kw, delta-connection for 4Kw and above.

WARRANTY:

Oxford motors are warranted to be free from defects in material, workmanship for a period of one year.
