R911263529

The MKD090B-047-GP0-KN (R911263529) is a digital AC synchronous servo motor from the MKD Series, engineered for high-precision motion control in demanding industrial automation environments. With a rated power of 4.8 kW, a rated torque of 9.9 Nm, and a top speed of 3500 RPM, this unit delivers the dynamic performance and positioning accuracy required by CNC machining centers, robotics systems, and precision indexing tables. Its resolver feedback system provides continuous, reliable rotor position and speed data, making it a natural fit for closed-loop drive configurations.R911263529

This motor ships without a holding brake and features a shaft with keyway per DIN 6885-1, along with a shaft sealing ring for added protection against contaminant ingress. A terminal box connection style simplifies cabinet layout and power wiring. The standard housing carries an IP65 protection rating, guarding against dust and water jets and ensuring consistent performance in harsh shop-floor conditions. Insulation Class F further extends thermal headroom during continuous-duty operation.R911263529

This listing is for a used and tested example that has been verified for operational functionality before sale. Used industrial servo motors from the MKD Series have a well-documented service life, and proper bench testing confirms the resolver signal integrity, winding resistance, and mechanical freedom that buyers depend on. Sourcing a tested surplus unit is a cost-effective path to maintaining production uptime when a replacement is needed quickly.R911263529

Compatibility spans a broad range of Rexroth Indramat drive controllers that accept resolver-based feedback, making integration into existing systems straightforward. Whether restoring a Weeke CNC machining center, upgrading a packaging line, or keeping a legacy automation cell running, this motor offers a proven combination of torque density, precision, and rugged German engineering at a fraction of the cost of a new unit.
