The Bosch Rexroth MPN R911331078 (MSK050C-0300-NN-M1-UG1-NSNN) is a synchronous servomotor built to DIN EN 60721-3-3 standards, with a natural convection cooling method. It supports axial vibration loads up to 10 m/s² within a 10 Hz to 2,000 Hz range, and can handle up to 40 N axial force. The motor features a plain shaft with a force-fit shaft hub connection and a B05 mounting style; shaft entry by liquids should be prevented during vertical installation. Bearings are compliant with ISO 281, enabling up to 30,000 hours operating life. It has a black chemical-resistant casing, is suitable for installation in any orientation, and includes an electrically-released holding brake rated at 6 Nm. The motor offers a continuous standstill current of 3.4 A and torque of 5.5 Nm at 100 K, with a maximum current of 12.4 A and peak torque of 15.0 Nm. Encoder feedback is provided by a multiturn absolute optical Hiperface encoder with 128 signal periods and a rotatable 240° connector. The winding code is 0300, winding inductivity is 45,100 mH, and the unit is certified to CE, cUL, and RoHS standards.

Frequently Asked Questions

How does the MSK050C-0300-NN-M1-UG1-NSNN handle safety-critical axis positions during emergency stops?

It includes an electrically-released 6 Nm holding brake. This enables secure shaft locking during power-off or fault conditions.

What encoder interface considerations apply for high-resolution feedback in closed-loop systems?

The integrated optical multiturn absolute encoder uses a Hiperface interface. It provides high-resolution position data with integrated communication and power in a single connection.

Can natural convection in this motor support stable operation in sealed control cabinets?

The natural convection cooling supports quiet and enclosed operation. Thermal load should be monitored in high-duty or non-ventilated enclosures.

Is the MSK050C-0300-NN-M1-UG1-NSNN appropriate for installations with ATEX or safety classification needs?

It supports standard and explosion-protected configurations. This broadens its deployment in hazardous or regulated environments.

Will this unit deliver consistent output torque across a variable load cycle?

It maintains 5.5 Nm continuous torque and allows up to 15 Nm peak at 12.4 A. This ensures predictable torque delivery under varying load profiles.
