SIMOTICS SD200 AC Motor

Providing high productivity and energy-efficient operation in all torque ranges, the SIMOTICS SD200 severe-duty motors are built to power pumps, fans, compressors, hoists, winders, and similar equipment in harsh environments. The motors offer 75-800 hp output and feature 444-5013 cast-iron frames for operation in 460 and 575V ranges. They meet NEMA Premium MG1 Table 12-12 efficiencies. Options include IP56 ingress protection, encoders, brakes, and blowers, plus others to suit application requirements.

On these motors, the frame, end-shields, fan guard, and terminal box are all cast-iron. An offset rotor bar provides improved efficiency, while larger bars and end rings reduce resistance. Each die-cast aluminum rotor assembly is balanced for extended bearing life and includes a high-strength C1045 carbon steel shaft for maximum performance.

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 NEMA MG1 2014 Part 31, making these motors suitable for variable speed drives in constant torque and variable torque.

Siemens SIMOTICS SD200 frame size 440 low-voltage, severe-duty AC motors will be introduced at EASA 2021.  They are designed for use in the harsh environments of oil & gas/petrochemical, grain, rock product, plus food-and-beverage and other markets with Division II, Class 1 and 2 conditions present.
