According to explosion protection in zone 1
gas, the use of Simotics XP motors in the IIB version is possible. If hydrogen or acetylene are present, the IIC version is required. Both versions, IIB and IIC, are characterized by robustness, high
availability, and a consistent platform concept. In addition, further options
are available for the motors: Premium insulation enables speed-controlled
operation with any converter with output voltages up to 690 V without any
filter. Variants with reduced starting currents and the availability of the
wide range of options with monitoring by PTC sensors (PTC thermistors) and
PT100 (thermometers), with specific painting systems and modular attachments,
such as speed encoders and brakes, complete the portfolio.
All common types of protection are covered by the consistent and integrated Simotics XP platform for explosion-proof motors and can be easily configured and adapted using the Drive Technology Configurator provided by Siemens. Simotics XP motors offer plant operators and machine builders a simple spare parts inventory, standardized tools, and ordering processes.
