Siemens has combined its Chemstar product range with the properties of its Simotics XP low-voltage motor platform. The new generation of motors are available in a range from 0.25 – 500 kW covering ignition protection spectrum for zones 1, 2, 21 and 22 in Ex db, Ex eb, Ex ec, Ex tb and Ex tc. The motors are made with a highly robust design comprising an enclosure and bearing plates in grey cast iron and a fan cover in steel. The high level of efficiency (class IE3) and easy-maintenance design mean low operating costs for the user. A number of pre-defined industry-specific options are available, such as special coatings with category C4 high-level corrosion protection, stainless steel screws and bolts or extended warranty periods, which enable these motors to be used in the chemical or oil and gas sectors. The standardised documentation is flexibly configured to allow adaptation to both simple and highly complex projects.
