SIMOTICS HV C air-cooled

Extremely reliable, low vibration levels and flexible – with a unique power density

SIMOTICS HV C air-cooled

SIMOTICS HV C air-cooled is the new ultracompact, extremely reliable high-voltage and trans-standard motor for applications in safe areas (where there is no risk of explosion) – as well as a hazardous Zones 2 and 22 with types of protection Ex ec and Ex tc.

The real highlight is the revolutionary cooling concept, which is used for all air-cooled versions of this platform. Fin cooling, tube cooling and an internal cooling circuit are smartly combined, and in conjunction with the vibration-optimized, rugged enclosure design, ensure a long service life and reliability – even when operating under extreme conditions. They have a very low noise level and have a unique power density with approximately 10 – 15% higher power output from the same frame size. The innovative design concept ensures maximum flexibility when it comes to integrating the drives in plants and systems – and also reduces the cabling costs.

Another plus point is that now all compact, air-cooled high-voltage and trans-standard motors – whether with or without explosion protection – now share a standard platform. The associated standard construction and handling principles reduce costs over the complete lifecycle: extending from planning and procurement through engineering and plant/system integration up to service, storage and spare part management. But there's more: Using the optional SIMOTICS CONNECT 600 connector box, SIMOTICS HV C can be integrated into the digital SIDRIVE IQ platform. This facilitates Cloud-based analysis of the status data, therefore allowing the drive system to be subsequently optimized.

The revolutionary cooling system for air-cooled versions of SIMOTICS HV C combines a fin-cooled enclosure with integrated tube cooling.
