Your benefits

Powerful operation
The explosion-proof planetary servo gearmotors enable high torque ratings for comparably smaller designs.

Safe operation
The high, ATEX-compliant explosion protection also ensures safe operation in potentially explosive environments.

Precise operation
This allows you to optimally perform even the most complex tasks and processes.

Dynamic servo gearmotors for explosion-proof precision applications

When designing your systems, you can expect power density, dynamics, and high explosion protection in accordance with Directive 94/9/EC (ATEX), or as of April 20, 2016 of the EU Directive 2014/34/EU (ATEX), right from the outset. The low-backlash, explosion-proof planetary servo gearmotors from the PS(K)F..CMP.. series stand out from the crowd as they are extremely cost-effective and flexible.

This is achieved through the compact combination of powerful planetary gear units and dynamic synchronous servomotors from the CMP.. series. Planetary servo gear units account for constantly low rotational clearances, high torsional rigidity and torque. The synchronous servomotors provide precise control and high dynamics.

This enables you to optimally coordinate different precision sequences and achieve powerful performance, even with high cycle rate requirements. Thanks to their high degree of efficiency, reliability, and durability, our explosion-proof planetary servo gearmotors offer you an economically sound modular solution. The PS(K).F..CMP.. explosion-proof planetary servo gearmotors are available in equipment group II in categories II2GD (for stand-alone gear units with adapters only) and II3GD (for directly mounted planetary servo gearmotors).

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