A wide variety of sizes and an unlimited range of applications. The broad spectrum of explosion-proof R..CMP.. helical servo gearmotors can be specifically configured for all safety-relevant areas.
Power, dynamics, and precision with our 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.
At SEW‑EURODRIVE, we also offer a number of practical configuration tools. You will soon discover that our 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 our wide range of accessories. This enables us to offer you even more flexibility and freedom in terms of planning and implementation.
Our 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 6000 Nm 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.
