IEC/EN 60034-30 standard was published by the nternational Electrotechnical Commission in October 2008.

The standard defines efficiency classes for motors and harmonizes the currently different requirements for induction motor efficiency levels around the world. It will hopefully put an end to the difficulties encountered by manufacturers producing motors for the global market. Motor users will benefit through the availability of more transparent and easier to understand information.

What motors are covered by the standard?

The scope of the standard is wider than that of the agreement previously in force in Europe. IEC 60034-30 covers almost all motors (for example standard, hazardous area, marine, brake motors):

• −− Single-speed, three-phase, 50 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 50 and 60 Hz.

What motors are Excluded by the standard:

• −− Ex – motors acc. to ATEX 94/9/EC.
• −− Motors with directly mounted-on brake.
• −− Smoke extraction motors >400°C.
• −− Built-in motors as well as completely submerged motors.
• −− Motors developed for site altitude.
• −− > 1000m and Tamb > 40°C resp. < -15°C.
• −− Coolant temperature >25°C or <5°C for water-cooled motors.
• −− Motors which are integrated in a system and the efficiency of which can only be measured in the complete system.
