SIMOTICS SD200

One Motor for Any Challenge

Built for the Harshest Industries and Applications

A wide range of industries already trust their operations to Siemens severe-duty motors — from oil and gas, petrochemical, pulp and paper, and mining, to food and beverage, water and wastewater, minerals, and more. The next-generation SIMOTICS SD200 motor is built to power fans, compressors, pumps, conveyors, hoists, winders and similar equipment in these tough environments day after day, night after night. The reliable motor design ensures a long, trouble-free life backed by a three-year warranty.

Frame and End Shields

The SIMOTICS SD200 features a cast-iron frame, end shields and an easy-to-access, diagonally split, oversized terminal box. The terminal box comes with a neoprene gasket and includes a heavy-duty ground lug and non-wicking leads that are clearly and permanently marked. A total of 38 optional positions are available, most of which are field-modifiable. These features — along with the high-strength zinc-plated hardware, epoxy paint and stainless steel nameplate — provide exceptional structural integrity and high resistance to rust and corrosion, which makes the motor more than suitable for severe-duty applications in harsh environments.

Rotor and Stator Windings

A unique offset rotor bar design ensures 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 C5-grade electrical steel laminations and copper electrical magnet wire to further the reduction in losses.

Insulation

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 wire 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) applications. All windings are tested for CIV.

Cooling Systems

A non-sparking, bidirectional 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 provided for all frame sizes.

Bearings

Single-shielded bearings are used for better bearing protection against contaminants.
