What is IEC 60034-33:2017 ?

IEC 60034-33:2017 is an essential international standard that defines the technical specifications and requirements for the efficiency classes of rotating electrical machines. This standard is published by the International Electrotechnical Commission (IEC) and is widely recognized and implemented in the electrical engineering industry.

The primary objective of IEC 60034-33:2017 is to establish a universal method for determining the energy performance of various types of motors and generators. This standard provides a set of guidelines and testing procedures to evaluate the efficiency of these machines, helping manufacturers produce more energy-efficient products.

Efficiency Classes

The efficiency classes of rotating electrical machines are determined by their ability to convert electrical energy into mechanical work. The efficiency classes are categorized into five levels, as per IEC 60034-33:2017:

E-1: The least efficient, with a power factor of less than 0.15.

E-2: The second least efficient, with a power factor of between 0.15 and 0.25.

E-3: The third least efficient, with a power factor of between 0.25 and 0.35.

E-4: The fourth least efficient, with a power factor of between 0.35 and 0.45.

E-5: The most efficient, with a power factor of greater than 0.45.

The efficiency classes of rotating electrical machines are determined by their ability to convert electrical energy into mechanical work.
