SIMOTICS SD Severe Duty Motors

The Severe Duty motors with gray cast iron frames are especially rugged. This makes them the first choice for applications in the toughest of environmental conditions. They have outstanding performance both in dust loading and in vibration as well as in the aggressive atmospheres that prevail in the petrochemical and process industries. Their design supports optimized heat dissipation and offers the same handling as the general purpose variants.
