Challenger Series IE2 Motors

  • Overview
  • The New IS:12615 : 2011 : is based on the international standard IEC 60034-30 (2008) which defines New efficiency classification for single speed, three phase, induction motors. The new IS: 12615 covers single speed, three phase, 50 Hz, cage induction motors that:

    – Have rated voltage 1000V
    – Have a rate output 0.37 KW to 375 KW
    – Have either 2,4, or 6 poles;
    – Meet frame size to output relation as stipulated in IS: 1231c(for outputs covered by IS:1231);
    – Are rated on the basis of either duty S1 (continuous duty) or S3 (intermittent periodic duty) with rated cyclic duration factor of 80% or higher
    – Are capable of opening direct on-line
    – Are designed for operation on virtually sinusoidal and balanced 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 IP 44 or superior
    – The efficiciency classed defined are:
    IE1 – Standard Efficiency
    IE2 – High Efficiency
    IE3 – Premium Efficiency
    The New IS: 12615 also stipulates that for motors to be classified as “Energy Efficient”, these must meet at least IE2 efficiency values.
