The Bosch Rexroth synchronous servomotor R911372611 (MSK050C-0300-NN-M1-UG1-NNPN) is designed for use in environments that may expose it to aggressive media, featuring a corrosion-resistant housing and a secondary ground conductor of at least 4 mm². It is equipped with a multiturn absolute Hiperface optical encoder offering 128 signal periods and a rotatable 240° connector. The motor includes an electrically released 24V holding brake with 6 Nm torque, a plain shaft with radial shaft sealing and DS thread, and supports natural convection cooling. It has a 3.4 A continuous current (100K) and 5.5 Nm continuous torque (100K) at standstill, with maximum values of 12.4 A and 15.0 Nm, respectively. Optimized for operation in Zone 2 and Zone 22, it performs at altitudes up to 1,000 m with potential performance reduction above this range. The motor length is 'C', size '050', and windings are specified as code '0300'. Appropriate caution must be observed during installation, de-energized operation, and disconnection of plug connections.

Frequently Asked Questions

How does the MSK050C-0300-NN-M1-UG1-NNPN motor simplify cable layout in compact machine enclosures?

The 240° rotatable encoder connector allows flexible cable exit directions. This avoids rigid routing and eases access during installation or maintenance.

What trade-offs does high winding inductivity introduce in real-time positioning control?

A 45.100 mH inductance enhances current smoothness and position stability. It slightly limits response speed during fast current ramp demands.

Will this model maintain performance without active airflow in thermally sensitive applications?

Natural convection cooling enables quiet, sealed operation. Heat dissipation remains stable under moderate duty but may require thermal assessment in tight enclosures.

How does the MSK050C-0300-NN-M1-UG1-NNPN handle high-torque positioning in short bursts?

It supports up to 15 Nm of torque during transient load peaks. This ensures reliable precision when inertia changes suddenly.

Is this motor natively supported by Rexroth drive controllers?

The MSK050C-0300-NN-M1-UG1-NNPN integrates directly with HCS series drives. That ensures fast commissioning and eliminates interface mismatches in standard IndraDrive systems.
