DCS Siemens New Simotics SD200 Frame Size 440 Low Voltage 1 400

Siemens announces the immediate availability of the SIMOTICS SD200 severe-duty motor in frame size 440 as its latest offering in the low-voltage SIMOTICS motor family. Cast-iron motors meet or exceed NEMA Premium® efficiency standards for oil-and-gas/petrochemical, pulp-and-paper, grain and rock processing, and other harsh environments.

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. With a three-year warranty, 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.

On these motors, the frame, end-shields, fan guard and easy-access, diagonally split, oversized terminal box are all cast-iron. Complementing this construction are zinc-plated hardware, epoxy paint and stainless-steel nameplates for long life and easy identification in the field. A unique offset rotor bar provides improved efficiency, while larger bars and end rings reduce resistance. Each die-cast aluminum rotor assembly is dynamically balanced for extended bearing life and includes a high-strength C1045 carbon steel shaft for maximum performance. Premium C5-grade steel laminations and copper magnet wire are standard.

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).

The Siemens Product Manager for Low-Voltage NEMA Motors, Oscar Palafox, explains, “One of the features of the SD200 is its flexibility in the field, as the motor can be switched from F1 to F2 and F3 orientation with ease. Plus, the safety features on this new line are unmatched by competition. Full H-Class conformity provides winding protection, while the swivel hooks are a significant improvement over eyehooks for handling of these heavy units. In addition, the unique Siemens composite insulation on the SD200 is a cost-saver over the ceramic bearing alternative with ten times the resistance of other solutions in the market. Finally, the NEMA Premium® efficiency is a guarantee of long performance life with very tight deviation of losses. Shaft current remains more consistent for better uptime.” Palafox further notes this new line affords users Division II, Class 1 (gas) and Class 2 (dust) protection.

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-and-gas / petrochemical, grain, rock product, plus food-and-beverage and other
markets with Division II, Class 1 and 2 conditions present.

Put to the Ultimate Test – Part 1: Torsion Tests by HELUKABEL

DCS Put to the Ultimate Test Part 1 Torsion Tests by HELUKABEL 1 400x275

Cables and wires in industrial robots and other moving machine parts are often required to withstand extreme stresses caused by torsion. Constant repetitive movements put materials under considerable strain. At the same time, operators expect components to function perfectly and reliably throughout their entire service life to avoid disruptions, outages and safety hazards.

For this reason, at HELUKABEL, we simulate intensive and continuous torsion stresses under realistic conditions with our high-tech testing equipment in Windsbach. We have several types of apparatus for doing this because some of our customers, for example those in the automotive industry, have very precise specifications for how a torsion test is carried out. The tests show that our cables and wires withstand speeds up to 1,000°/s, accelerations up to 2,000°/s² and torsion angles up to 720°. Hence, we make sure that each product always meets our customers’ high standards, and that they receive the impeccable quality they rightly expect from us as a leading supplier of cables, wires and accessories for more than 40 years.
