Power, dynamics, and precision with the explosion-proof gearmotors


Save time and benefit from the modular options for explosion-proof helical servo gearmotors from the R..CMP.. series. This means you will always have an explosion-proof drive that is optimally suited to your individual requirements.


SEW‑EURODRIVE also offers a number of practical configuration tools. You will soon discover that the explosion-proof helical servo gearmotors are the perfect fit for your applications. This is particularly true for compact solutions requiring a high level of precision. The R..CMP.. helical servo gearmotors enable particularly complex processes to be optimally implemented in potentially explosive system environments. This means a high level of performance, efficiency, and safety for all of your systems. You can also benefit from the wide range of accessories. This offers you even more flexibility and freedom in terms of planning and implementation.


The explosion-proof R..CMP.. helical servo gearmotors are always the right choice – particularly for lightweight system constructions. You save valuable installation space and get the most out of your installation options. Powerful peak torques of up to 6000Nm also give you real power and precise dynamics.


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