The Siemens Drive Technologies Division now offers IEC motors consistently across the efficiency classes IE2 and IE3 covering the application range of EU Regulation 640/2009 from 750 W to 375 kW. Furthermore, the motors are available for the NAFTA market with EISA-certification in the Energy Efficiency and Premium Efficiency classes.
Siemens offers the IEC motors in two different series: General Purpose and Severe Duty. The General Purpose motors with aluminum housings and shaft heights of between 80 and 160 and an output of 550 W to 22 kW are used mainly for pumps, fans and compressors. The Severe Duty version has a particularly rugged cast iron housing which makes it suitable for use in tough conditions such as those found in the process industry. It is available in the power range from 2.2 kW to 375 kW and with shaft heights between 100 and 315.
