Description for Felm F3 250M-4 Motor
Efficiency Classes of Motors and Measuring Methods The “efficiency” describes how efficiently an electric motor transforms electrical energy into mechanical energy. Previously in Europe, low voltage three-‐phase motors have been graded and marketed in three efficiency classes – EFF3, EFF2 and EFF1 – based on a voluntary agreement between motor manufacturers and the European Commission. This classifica-on system is well proven and has now been adapted in many countries around the world. Unfortunately, other countries have also developed their own na-onal systems, which are very different from the European system. That was the reason for the German motor manufacturers in ZVEI, with the support of their European neighbours, to develop an energy efficiency standard for the Interna-onal Electrotechnical Commission (IEC). The objec-ve was to have a common interna-onal standard that replaces all the different na-onal systems. This project was successful and the objec-ve has been met. The new interna-onal standard, IEC 60034-‐30:2008, defines efficiency classes IE1, IE2 and IE3 for three-‐ phase motors. This ensures a common interna-onal basis for the design and classifica-on of motors as well as for na-onal legisla-ve ac-vi-es. At the same -me, the IEC developed improved methods for determining the efficiency of these motors. The interna-onal standards IEC 60034-‐30:2008 (classifica-on) and IEC 60034-‐2-‐1:2007 (measuring methods) have been adopted as European standards without any changes as EN 60034-‐30:2009 and EN 60034-‐2-‐1:2007. For the sake of simplicity, the following sec-ons will refer to the IEC standards only.Recommended Products For Felm
