The Bosch Rexroth R911335003 (MSK101C-0450-NN-M1-AG2-NNNN) is an IndraDyn S synchronous servomotor that operates with an external drive controller. The motor features natural convection cooling, a plain shaft, and a power connector located on the A-side. It utilizes a multiturn absolute optical encoder with Hiperface interface, delivering 128 signal periods. Specification highlights include a holding brake torque of 70 Nm, continuous current at standstill (100 K) of 28.6 A, continuous torque at standstill (100 K) of 36.5 Nm, maximum current of 113.0 A, maximum torque of 110.0 Nm, and winding inductivity of 3,300 mH. The servomotor is designed for environments with high relative humidity (up to 95%) and an ambient temperature change rate of 0.5°C/min. Transportation and storage must be within -20°C to 80°C and -20°C to 60°C, respectively. The grounding connection via the motor cable is required for operational safety.

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.
