Simotics SD 200 low-voltage, severe-duty AC motors have gained 75-800 hp outputs, feature 444-5013 cast iron frames for operating in 460 V and 575 V ranges, and meet or exceed NEMA Premium MG1 Table 12-12 efficiencies. They also offer IP56 ingress protection, encoders, brakes, blowers and other options. A unique offset rotor bar provides improved efficiency, while larger bars and end rings reduce resistance. For insulation, Class-H non-hygroscopic system with NEMA Class B temperature rise provides extra thermal life.
