The SIMOTICS SD100 severe duty motors are designed and built for long, trouble-free life in harsh environments. Industries from petrochemical, pulp and paper and mining to food and beverage, water and wastewater, minerals and more trust their operations to the SD100. They power fans, compressors, pumps, conveyors, hoists, winders and many more applications in the toughest environments day after day, night after night. Built for long, trouble-free life, they are backed up by a 3-year warranty.All SD100 motors are inverter duty and have their VFD ratings right on the nameplate. They are designed and manufactured to meet or exceed NEMA Premium® efficiency (MG1 Table 12-12); higher efficiency is available on many sizes with the optional copper rotor. A wide selection of options, among them IP56 ingress protection, encoders, brakes and blowers, plus other QuikMOD modifications provide higher flexibility and reliability in diverse operating conditions.

The SIMOTICS SD100 frame, end shields, fan guard and easy-to-access diagonally split, oversized terminal box are all cast iron. The terminal box features a neoprene gasket and includes a heavy duty ground lug and clearly and permanently marked non-wicking leads. These characteristics plus high strength zinc-plated hardware, epoxy paint and stainless steel nameplates provide exceptional structural integrity and corrosion resistance and make them ideal for severe duty applications in harsh environments.
A unique offset rotor bar design provides improved efficiency, while larger bars and end rings reduce resistance for lower rotor losses. Each die cast aluminum rotor assembly is dynamically balanced for extended bearing life and includes a high-strength carbon steel (C1045) shaft for maximum rotor performance.
The stator is manufactured with premium electrical C5-grade steel laminations and copper electrical magnet wire that furthers the reduction of losses.
The proprietary Class F non-hygroscopic insulation system with NEMA Class B temperature rise provides an extra margin of thermal life. The varnish system ensures maximum winding penetration to provide protection from moisture, corrosion and electrical shock. This insulation system meets or exceeds NEMA MG1 2014 Part 31 making the motors suitable for variable speed drives in constant torque (4:1) and variable torque (20:1). All windings are tested for CIV.
A non-sparking, bi-directional fan is locked and keyed to the shaft. Its low-inertia design reduces windage losses, improves airflow, reduces noise and provides dependable cooling. Cast Iron fan covers are standard for all frames sizes.
Single shielded bearings and V ring slingers are used for optimum bearing protection against contaminants. Inpro/Seal® bearing isolators are available on both ends.
