The Bosch Rexroth Indramat MSK101C-0450-NN-M1-AG2-NNNN is a precision IndraDyn S Synchronous Servomotor designed for high-performance industrial automation. As part of the MSK IndraDyn S Synchronous Motors series, this motor offers a Maximum Torque of 110.0 Nm and a Continuous Torque at Standstill (100 K) rating of 36.5 Nm. With a Rated Speed Code of 0450, it delivers accurate speed regulation essential for robotics, CNC machinery, and servo-driven assembly lines. The motor’s ability to maintain precise positioning under load makes it ideal for demanding motion control applications.

This standard-design motor features Natural convection cooling and a plain shaft type, ensuring reliable thermal management without auxiliary fans. It employs an Optical encoder with Multiturn Absolute turn type and a Hiperface interface, offering 128 signal periods resolution for sub-micron positional accuracy. The Power Connector is located on the A-Side for straightforward electrical integration. Notably, the MSK101C-0450-NN-M1-AG2-NNNN includes an electrically released Holding Brake with 70 Nm torque for secure load retention during power interruptions. The winding inductivity of 3,300 mH and a Maximum Current rating of 113.0 A support dynamic response and high acceleration demands.

Engineered for compatibility, this servo motor requires a dedicated Cooling FN unit to maintain optimal operating temperatures, extending service life and ensuring consistent performance. The robust design and natural convection cooling contribute to long-term durability and reduced maintenance. High-resolution feedback via the encoder system enhances control loop stability and energy efficiency in precision tasks. By combining strong torque reserves, a versatile interface, and secure holding capabilities, the MSK101C-0450-NN-M1-AG2-NNNN delivers reliable and efficient motion control, boosting productivity in modern industrial environments.

Frequently Asked Questions

What distinguishes the MSK101C-0450-NN-M1-AG2-NNNN encoder system, and how does Hiperface aid servo control startup?

The motor employs an optical multiturn absolute encoder using the Hiperface interface, so position is known at power-on without homing. Its absolute feedback lets drives commutate immediately for avoiding “wake-and-shake” routines and enabling tighter low-speed regulation.

How does the 3,300 mH winding inductivity influence current ripple and loop stability in MSK101C-0450-NN-M1-AG2-NNNN?

The higher phase inductivity filters current ripple from PWM modulation for easing demands on the current controller and reducing torque pulsation. It improves velocity-loop linearity and helps maintain commanded torque during dynamic load steps.

How does the 70 Nm electrically-released holding brake contribute to functional safety and uptime?

The brake statically secures the axis to prevent drift during power loss or e-stop for protecting tooling and workpieces. Its electrical release enables controlled re-engagement without mechanical re-zeroing on power restore.

What advantages does an A-side power connector bring in cabinet and field wiring for MSK101C-0450-NN-M1-AG2-NNNN?

Its consistent A-side orientation improves harness routing, bend-radius planning and EMC separation from feedback lines. It also streamlines identical cable lengths across mirrored machines for easing spares and reducing commissioning variance.

How does maximum current (113 A) relate to acceleration capability on MSK101C-0450-NN-M1-AG2-NNNN with heavy end-effectors?

Its high allowable phase current delivers short-term torque peaks for aggressive jerk-limited profiles for moving inertia quickly without saturating the current loop. Its proper drive limits and thermal models keep copper temperatures inside safe operating regions.
