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.



SIMOTICS HV Asynchronous Squirrel Cage Compact Motors (IEC)

Compact motors designed for standard and extreme protection requirements

The high voltage compact IEC motors featuring asynchronous technology cover a power range from 150 kW to 7 MW, at shaft heights from 315 up to 1000 mm, in all relevant cooling types for low installation heights – in addition to classic fin cooling, also available with tube cooling and water jacket cooling. With these versions, they seamlessly cover the corresponding power and application ranges – from basic or standard up to sector-specific applications. They can also address extreme requirements with degree of protection up to IP66, in special designs up to IP68 and all types of explosion protection. The compact motors sets themselves apart as a result of its high power density and compact design that applies across the board. Further, as a result of their outstanding reliability, as well as low maintenance, they boost plant and system availability and reduce energy costs based on their high efficiencies.
