Explosion Proof Electric Motors IE2

  • High Efficiency – IE2: Explosion-proof Electric Motors IE2

In accordance with this European regulation, UMEB offers now asynchronous AC motors efficiency class High Efficiency (IE2).

The new IEC 60034-30:2008 defines worldwide the following efficiency classes of low voltage three-phase motors, in the range from 0.75 to 375 kW.

IE1 = Standard Efficiency (comparable to EFF2)
IE2 = High Efficiency (comparable to EFF1)
IE3 = Premium Efficiency

The efficiency factor defines the efficiency of motors when transforming electrical into mechanical energy. For many years low-voltage three-phase motors in the European Union have been sold in three efficiency classes EFF3, EFF2 and EFF1. Energy efficiency classification systems have been introduced and well-proven in many countries all over the world. They unfortunately differ from each other in terms of scope, wording and values. That was the reason for the International Electrotechnical Commission IEC to develop and publish an energy efficiency standard which replaces all the different national issues. In parallel IEC developed and issued a new standard for the determining the motor efficiencies. The new standard IEC 60034-30 defines and harmonizes worldwide the efficiency classes IE1, IE2 and IE3 for low-voltage three-phase motors.
