SIMOTICS XP - details

Maximum safety, extremely rugged

The motors are certified for use in environments with ignitable gases and dusts. They are available in all of the usual types of protection.


For use in environments with explosiv

  • gases in types of protection "flameproof enclosure – Ex db", "increased safety – Ex eb" and "non-sparking – Ex ec"
  • dusts in types of protection Ex tb and Ex tc.

In addition, SIMOTICS XP motors set themselves apart as a result of their shorter project execution times, lower costs for planning, engineering and integration - up to service and stock inventory. All of these factors play a role in reducing lifecycle costs.

SIMOTICS XP was specifically developed for pumps, fans, compressors, extruders, separators and agitators in the process industry, for example, in the chemical/petrochemical industry, oil & gas, plastics, food and beverage as well as woodworking. These motors address a power range extending from 0.09 all the way up to 1000 kW and degrees of protection from IP 55 to IP 65; further, they are suitable for line operation (DOL) as well as converter operation (VSD).

SIMOTICS XP is also available in the sector-specific SIMOTICS XP Chemstar version. It is customized to address either the chemical industry or the oil and gas sector.

Rugged SIMOTICS XP motors with cast iron enclosure are especially suitable for drive applications in the process industry. On the other hand, SIMOTICS XP motors with aluminum enclosure are especially light, and are ideally suited for fan and compressor applications.

The old and new premium standard

For decades now, the CHEMSTAR name represents the premium class of explosion-protected motors. As highlight of the new platform concept, SIMOTICS XP CHEMSTAR links the best of two worlds: All of the expertise of the traditional LOHER CHEMSTAR on one hand – and the global motor competence and performance of Siemens on the other hand.

SIMOTICS XP CHEMSTAR satisfies all requirements and operates with outstanding reliability whether in the chemical and petrochemical industry, whether oil & gas from upstream through midstream to downstream processes. These unique characteristics are now complemented by the leading edge platform-based advantages of the SIMOTICS XP generation of motors.


Profit from the following main advantages:

  • Preconfigured option packages for the chemical industry as well as oil & gas, for example sector-specific paint finishes with Category C4 corrosion protection, non-rusting steel screws and bolts and a sector-specific extended warranty period.
  • Freely selectable options such as reduced starting currents, motor monitoring, reinforced bearings, tropical climate variant for extremely humid environments, special paint finishes and an offshore C5M-M classification
  • Documentation that can be flexibly adapted to simple or very complex projects
