Explosion-proof Motor Line
Siemens’ newest addition to its electric motor line is the XP100
series, rated from 1–300 hp (0.75–223 kW) and designed specifically
for hazardous operating environments. The XP100 motors
are NEMA Premium qualified, 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.
All motors feature a cast iron frame and bearing housings
for high structural strength, as well as 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. Each die-cast aluminum rotor assembly is balanced for
extended bearing life and includes a high-strength carbon steel
shaft for maximum performance. According to the company, the
motors’ stator insulation system design and components combine
for an anti-corona system that can withstand voltage spikes caused
by fast-switching IGBTs from adjustable speed drives.
