Your benefits

Exploit high speeds
The SPIROPLAN® right-angle servo gearmotors achieve top speeds at extremely small gear ratios.

Integrate running smoothness
The remarkably smooth, attenuated operation ensures safety in potentially explosive environments and guarantees precise dynamics.

Compact design for top speeds in potentially explosive areas

The explosion-proof SPIROPLAN® right-angle servo gearmotors from the W..CMP.. series offer dynamics and notable servo precision in the lower torque range.

They are also exceptionally efficient. Furthermore, the ATEX II2GD and II3GD designs ensure safety of performance in gas zones 1 and 2 as well as in dust zones 21 and 22.

The explosion-proof CMP.. motor range includes 6 different sizes in accordance with Directive 94/9/EC (ATEX), or as of April 20, 2016 of the EU Directive 2014/34/EU (ATEX). This enables you to achieve high flexibility and variability in your potentially explosive areas. With their accurate scalability, short response times, and precise dynamics, the SPIROPLAN® right-angle servo gearmotors from the W..CMP.. series guarantee strong performance – particularly for demanding automation tasks.

Due to their compact lightweight construction and angular design, these gearmotors also enable complex processes to be performed in confined spaces. The explosion-proof SPIROPLAN® right-angle servo gearmotors are available in both a foot-mounted and flange-mounted design – with either a solid or hollow shaft.

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