SIMOTICS SD Severe Duty motors

Key visual SIMOTICS SD

The Severe Duty motors with their rugged gray cast iron housing are the first choice for all important applications in normal industrial settings as well as under harsh ambient conditions. They operate reliably in a temperature range from -50 °C to +60 °C. Degrees of protection up to IP66 and a coating system up to C5 (offshore duty) permit operation in humid, dusty or vibrating environments as well as in aggressive atmospheres. This makes them ideally suited for the petrochemical industry and the general process industry. Their design supports optimum heat dissipation and thus enables very compact dimensions. The modular platform concept offers identical handling to the General Purpose series. This results in a shortened engineering phase and simplified spare parts management. SIMOTICS SD motors cover an integrated performance range from 90 W to 1,000 kW.

Standard SIMOTICS SD next generation motors

With SIMOTICS SD next generation, a new scalable generation of low-voltage motors is ready for digitalization. Thanks to their impressive performance and the additional versatility in their range of applications, this motor series ensures future-proof drive technology.

Dust and vibrations cannot slow them down, nor can aggressive environments in the process industry. Their optimized design allows compact dimensions with a high power density. A standardized range of options and the flexible terminal box concept allow easy integration in different plant configurations and applications.

Product overview

SIMOTICS SD Add and SIMOTICS SD Pro offer global certificates. They are therefore ready for use in all major world regions and markets. They can be used as standard in the European Union and North America. They are supplied with the electrical values stamped on the rating plate in accordance with IEC and EISA requirements. Like with the Eagle-Line for the smaller shaft heights, the motors represent a NEMA version electrically (mechanically acc. to IEC). In addition, many other country-specific certificates are available.
