Your benefits

Powerful operation
The dynamic explosion-proof helical-bevel servo gearmotors are designed for torques of up to 8000 Nm.

Achieve precision
State-of-the-art servo drive technology provides all the advantages of short response times and precise scalability.

Ensure safety
These servomotors are used in systems operated in particularly sensitive areas.

Powerful performance with our explosion-proof helical-bevel gearmotors

For drives used in areas with high gas or particle emissions, specific requirements must be met for explosion protection. Our explosion-proof K..CMP helical-bevel servo gearmotors offer a complete solution that is cost-effective and safe.

With dynamic, precise, and compact servo drive technology on the one hand and certified safety for potentially explosive system environments on the other. The explosion-proof K..CMP.. helical-bevel servo gearmotors guarantee a high degree of functionality in terms of power delivery and precision – especially when complex processes and process reliability are involved. Thanks to their precise scalability, unlimited range of variants, and wear-free design, the explosion-proof K..CMP.. helical-bevel servo gearmotors are always the unit of choice.

Certification according to ATEX includes equipment group II and equipment category 3. The combinations are available in II3GD and II3D design.
