Ensure safety
Explosion-proof helical-bevel servo gearmotors provide protection for equipment group II and categories 2 and 3.

Achieve high performance
Explosion-proof BS.F..CMP helical-bevel servo gearmotors impress with their power, precision, and compact design.

Optimum explosion-proof gearmotors

Force, precision, and safety come together to form a true unit in our explosion-proof BS.F..CMP.. helical-bevel servo gearmotors. Thanks to their compact design in the form of helical-bevel servo gearmotors, they offer you optimum mounting options and a wide variety of possible applications.

This is particularly relevant for potentially explosive areas where dust and gas emissions are a safety issue. Rotational clearances remain constantly low throughout the entire service life of this servo drive due to the high-endurance design of the running gears.

Take advantage of our large selection of gear unit-motor combinations for a wide range of applications that require high torques and precise performance. These combinations are also suitable for complex automation tasks in which several processes are merged to form an overarching process.

By using our explosion-proof helical-bevel servo gearmotors, you will obtain a high level of process reliability, efficiency, and cost effectiveness. The explosion-proof BS.F.. servo gearmotors are extremely robust and low-maintenance thanks to their high-quality manufacturing and precise tooth elements. This makes them even more efficient when combined with our CMP.. synchronous servomotors that can be precisely controlled.

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