SIMOTICS HV C flameproof is the new ultracompact flameproof high voltage motor, which ensures maximum safety and very reliable operation, even in highly explosive environments. The reason for the unique power density is a revolutionary cooling concept. This combines the principle of air circulating in the motor – together with tube cooling elements: Further, the SIMOTICS HV C flameproof sets itself apart as a result of its extremely rugged design for maximum reliability, even under harsh conditions, optimized vibration behavior – as well as extremely short delivery times and high on-time delivery for this power class.


Your advantages

  • Less space required and simpler integration into plants and systems as a result of the extremely compact design
  • Very safe and reliable, even in highly explosive, extreme environments
  • Extremely long lifetime as a result of the optimized temperature distribution
  • Minimized noise levels reduce noise attenuation measures/costs
  • Low weight simplifies handling and transport
  • Optimized vibration behavior for long plant and system lifetimes
  • Increased flexibility in plants and systems and simplified installation as a result of the variable terminal box position
  • Accelerated project execution for fast time-to-market
  • Maximum system transparency and higher productivity by integrating into digital system concepts



  • Cooling system, which combines the inner cooling circuit with tube cooling
  • Extremely high power density, which sets the benchmark in the flameproof motor market
  • Improved cooling – where hotspots are reliably avoided
  • Flow-optimized fan with explosion-certified design
  • As a result of the flameproof enclosure in Ex d and Ex d(e) predestined for Zone 1 where there is an extremely high risk of explosion
