Champion IE Series Motors

The IS: 12615-2011 for Energy Efficient Motors

The Indian Standard IS: 12615-2011 replaces the earlier IS:12615-2004. With this change, the efficiency classes eff2
and eff1 are no longer valid. This new standard defines new "International Efficiency" classes similar to IEC 60034-30
(2008).The IS:12615-2011 defines efficiency values for a motor to be classified as energy efficient. This standard covers single speed, three phase, 50Hz, Cage Induction Motors that,

  • Have rated voltage ≤1000V;

  • Have a rated output 0.75kW ≤ PN ≤ 375kW;

  • Have either 2, 4 or 6 poles;

  • Meet frame size to output relation as stipulated in IS:1231 (for outputs covered by this standard);

  • Are rated on the basis of either duty type S1 (continuous duty) or S3 (intermittent periodic duty) with rated cyclic
    duration factor of 80% or higher;

  • Are capable of operating direct on-line;

  • Are designed for operation on virtually sinusoidal and balance voltage conditions as defined in 7.2.1 of
    IS/ IEC 60034-1;

  • Designed for an ambient temperature not exceeding 40°C and altitude not exceeding 1000m;

  • Have degree of protection IP44 or superior;

  • Have method of cooling IC411 in accordance with IS 6362 (Part 0/Sec0):1995 / IEC 60034-6(1991);

  • Have service factor not exceeding 1.0.

This standard also stipulates that for a motor to be classified as energy efficient, it must meet as a minimum, efficiency class IE2. The losses and efficiency for motors conforming to this standard have to be determined as per IEC 60034-2-1(2007).

IE2 Series Motors

Champion – High Efficiency Motors

IE2 series motors are offered from 0.37kW – 375kW in 2, 4 & 6 Pole. These squirrel cage Induction motors confirming to the IS: 12615 / IEC: 60034-1 are offered in Cast Iron housing with IP 55 protection and with IC411 cooling as per IS: 6362 TEFC.

The Champion IE2 Series motors are offered for an Ambient of  50°C, for Altitude < 1000m, with Class F insulation, 63 Series bearing for frame 160 and above with identical bearings at DE and NDE which helps in reducing the inventory.
