Siemens has launched the SIMOTICS SD200 severe-duty motor in frame size 440 as its latest offering in the low-voltage SIMOTICS motor portfolio. Providing high productivity and energy-efficient operation in all torque ranges, these new cast-iron NEMA motors are built to power pumps, fans, compressors, hoists, winders, and similar equipment in harsh environments. The SD200 motors offer 75-800 hp output and feature 444-5013 cast-iron frames for operation in 460V and 575V ranges. They meet or exceed NEMA Premium^® MG1 Table 12-12 efficiencies. A wide selection of options are offered, including IP56 ingress protection, encoders, brakes, and blowers plus others to suit the applications presented.

For insulation, the Class-H non-hygroscopic system with NEMA Class B temperature rise provides an extra margin of thermal life. The insulation system meets or exceeds NEMA MG1 2014 Part 31, making these motors suitable for variable speed drives in constant torque (4:1) and variable torque (20:1). All windings are tested for Corona Inception Voltage (CIV).
