Siemens Industry Inc. introduced the XP100 (1-300 hp) line of motors, designed for hazardous operating environments such as the petrochemical and chemical processing, mining, and grain handling industries.

The Siemens line of XP100 motors are UL and CSA listed for gas and dust ignition-proof environments and are suitable for Division 1, Class I, Groups C and D, Class II, Groups F and G, hazardous area classifications. They are also available for drill rig duty in Division 1, Class I, Group D hazardous locations. Their advanced electrical design meets or exceeds the requirements of the Energy Independence and Security Act of 2007 (NEMA MG1 – table 12-12). Siemens is a NEMA Premium licensee. Therefore, all XP100 motors bear the prestigious NEMA Premium logo.

Available from stock with ratings from 1 hp through 300 hp and modifiable to specific customer needs, the XP100 motors combine durability, superior operating performance and energy efficiency into a single package.

“Siemens has been manufacturing motors since 1860, and the product development of the XP100 took into account the vast extremes that are required from our end users, allowing our design team to meet and exceed the expectations of our customers and government and industry certifications," says John Caroff of Siemens Drive Technologies Division.

The Siemens XP100 explosion proof motor features a cast iron frame and bearing housings that provide high structural strength.

In addition to the use of all cast iron construction, the XP100 features epoxy enamel paint, polycarbonate cooling fan, non-hygroscopic insulation, corrosion resistant hardware and stainless steel nameplate to reduce the effects of industrial contaminants, moisture and extreme weather conditions.

The stator insulation system design and components result in an anti-corona system that can withstand voltage spikes caused by fast switching IGBTs from adjustable speed drives. Each die cast aluminum rotor assembly is balanced for extended bearing life and includes a high strength carbon steel (C1045) shaft for maximum performance.
