IEC 60034-30: October 2008 defines three IE (International Efficiency) efficiency classes of single speed, three phase, cage induction motors.
- IE1 = Standard efficiency (efficiency levels roughly equivalent to EFF2 in Europe nowadays)
- IE2 = High efficiency (efficiency levels roughly equivalent to EFF1 in Europe nowadays and identical to EPAct in USA for 60 Hz)
- IE3 = Premium efficiency (new efficiency class in Europe nowadays and identical to "NEMA Premium" in the USA for 60Hz)
Efficiency levels defined in IEC 60034-30 are based on tests methods specified in IEC 60034-2-1: 2007. Compared to old efficiency classes acc. to CEMEP agreement the scope been expanded.
IEC 60034-30 covers almost all motors (for example standard, hazardous area, marine, brake motors):
• Single-speed, three-phase, 50 Hz and 60 Hz
• 2, 4 or 6-pole
• Rated output from 0.75 to 375 kW
• Rated voltage UN up to 1000 V
Duty type S1 (continuous duty) or S3 (intermittent periodic duty) with a rated cyclic duration factor of 80% or higher capable of operating direct online
Following motors are excluded from IEC 60034-30:
- Motors made solely for converter operation
- Motors completely integrated into a machine (for example, pump, fan and compressor) that cannot be tested separately from the machine.
