Asynchronous Squirrel Cage Motors (IEC)

The perfect motor for every application

SIMOTICS high voltage asynchronous IEC motors are the perfect solution for applications which call for high efficiency, maximum reliability, compact construction and running smoothness. They are available for mains and converter operation in power ratings from 150 kW up to 38 MW, voltage from 2 up to 13.8 kV, 2-16 poles, speeds up to 15,900 rpm, all usual cooling types, degree of protection up to IP66, in all usual types of explosion protection, also double protection. Suitable also for demanding environments, they fulfill all of the international certifications and sector-specific requirements.


Asynchronous Squirrel Cage Motors (IEC)

Below are four categories of high voltage asynchronous squirrel cage motors (IEC) to help filter out and focus your search for the right motor to match your project and application specifications based on key features like shaft heights, protection, power or cooling type.
