New IE2 & IE3 Series:

The New 15:12615-2011 is based on the International Standard IEC 60034-30 (2008) which defines New Efficiency Classification for single speed, three phase, induction motors.

The IS: 12615-2011 covers single speed, three-phase, 50Hz, cage induction motors that:

• Have rated voltage < 10000V
• Have a rated output 0.37kW
• Have either 2,4 or 6 poles
• Meet frame size to output relation as stipulated in IS:1231 (for outputs covered by IS:1231)
• 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 balanced voltage conditions as defined in 7,2,1 of IS\IEC 60034-1,
• Designed for an ambient temperature not exceeding 400C and altitude not exceeding 1000m
• Have degree of protection 1P44 or superior
• Have method of cooling 1C411 in accordance with 1S 6362\ IEC 60034-6
• Have service factor not exceeding 1.0

The Efficiency classes defined are:

• IE1-Standard Efficiency
• IE2-High Efficiency
• IE3-Premium Efficiency

The IS:12615-2011 also stipulates that for motors to be classified as "Energy Efficient", these must meet at least IE2 efficiency values.

Two case studies are given on page Sand 6, showing savings through 1E2 and 1E3 range of motors over 1E1.
