The Bosch Rexroth synchronous servomotor R911325668 (MSK050C-0450-NN-M2-UG1-RNNN) is engineered for operation at elevations below 1,000 meters and requires professional installation per official documentation. It is suitable for use in non-hazardous locations and incorporates natural convection cooling, necessitating a 140-minute cooling period after use. This unit features a plain shaft with a radial sealing ring, an electrically-released holding brake with 6 Nm torque, and a drive-controlled brake mechanism. The integrated optical multiturn absolute encoder utilizes EnDat2.1 interface, offering 2,048 signal periods and a 240° rotatable connector. Key specifications include a C length, size 050, winding code 0450, 5.2 A continuous current at standstill (100 K), 5.5 Nm continuous torque at standstill (100 K), 18.8 A maximum current, 15.0 Nm maximum torque, and a winding inductivity of 20,200 mH. Secure connection of all connectors is required during operation.

Frequently Asked Questions

How does the MSK050C-0450-NN-M2-UG1-RNNN ensure safe axis retention in vertical or emergency stop conditions?

It includes an electrically released holding brake rated at 6 Nm. This secures mechanical load positioning when drive power is off or interrupted.

What type of feedback resolution does the encoder provide for advanced closed-loop motion tasks?

It uses optical multiturn EnDat2.1 encoder technology with 2048 signal periods. This supports high-precision positioning with digital data reliability.

Is the MSK050C-0450-NN-M2-UG1-RNNN suitable for noise-sensitive, passively cooled enclosures?

It uses natural convection for heat dissipation. This enables fanless operation in sealed or acoustically restricted environments.

What is the current behavior under rated load at thermal limit in dwell-heavy cycles?

It delivers 5.5 Nm torque with a continuous current of 5.2 A at 100 K. This ensures thermal consistency under prolonged holding conditions.

How does the shaft design contribute to alignment-critical drive setups?

It uses a plain shaft for direct-fit coupling. This simplifies axial alignment and enhances smooth mechanical integration in servo assemblies.
