November 27, 2017 - With the introduction of its Simotics SD Add low-voltage motors, Siemens is extending the application scope of the Simotics SD low-voltage motor series it launched at the beginning of this year. By offering low start-up current levels, this addition to the series is designed to open up greater application scope: for instance, to comply with sector-specific requirements in the process industries, or in fields requiring enhanced grid stability by reducing grid loads in the event of voltage dips. The availability of country-specific certificates means that these motors can be used without restrictions in all regions and markets of importance around the world.
Simotics SD Add with efficiency classes IE3 and IE4 has a special electrical design designed to enable the start-up current levels in the Simotics SD Add to be reduced while retaining the same size. Low start-up currents increase the service life of the motor, as they reduce the incidence of torque shocks, which stress the motor windings both thermally and also due to electrodynamic forces. This design also enables supply cables, control cabinets, protection equipment and industrial controls to be more compactly dimensioned. Lower start-up current levels mean that grid loads due to disturbing voltage dips can be reduced.
To simplify commissioning, servicing, spare part procurement and the attachment of optional components, the Simotics SD Add motors are fitted as standard with a DataMatrix code. This enables all relevant information such as technical data, spare parts and operating instructions for the individual motors to be accessed on mobile terminals using the Simotics Digital Data App.
