The R911405383 (MSK101C-0450-FN-M1-BG2-NNNN) is an IndraDyn S synchronous servomotor featuring a plain shaft, 70 Nm electrically-released holding brake, and is equipped with a multiturn absolute optical encoder (128 signal periods, Hiperface interface). This motor is designed for liquid cooling (FN), operates with a continuous current of 28.6 A and produces up to 36.5 Nm continuous torque at standstill (100 K). Maximum current is 113.0 A with a peak torque of 110.0 Nm; winding inductivity is 3,300 mH. The unit includes a standard M58 fixed flange socket, B-side power cable exit, and threaded connectors for both power and encoder. Proper installation requires specific fastening elements and trained specialists. The device supports up to 3000 m installation elevation and belongs to climatic category 3K4, tolerating sinewave oscillation in stationary mode and must be handled to avoid shaft or flange damage; the holding brake does not provide personnel protection. Mistakes in handling coolant can result in short-circuiting.

Frequently Asked Questions

What advantages does the Hiperface optical, multiturn absolute encoder bring to MSK101C-0450-FN-M1-BG2-NNNN in closed-loop motion?

Its sine/cosine plus RS-485 absolute channel provides fine interpolation (128 periods) and absolute multi-revolution tracking for simplifying homing and improving low-speed smoothness. It enhances position fidelity under dynamic load changes and supports precise synchronization.

How is the 70 Nm electrically released holding brake of MSK101C-0450-FN-M1-BG2-NNNN typically used?

It secures vertical axes or suspended loads during power-off for enabling safe static holding and controlled restart. Its electrical release integrates with drive interlocks to prevent unintended motion during maintenance or emergency stops.

What continuous and peak capability should designers assume at 100 K for MSK101C-0450-FN-M1-BG2-NNNN, and how does that map to motion profiles?

Its 36.5 Nm at 28.6 A continuous and up to 110 Nm at 113 A for short bursts. It is used to shape acceleration, dwell and braking intervals while staying within thermal and RMS current limits.

Why is a plain shaft advantageous for MSK101C-0450-FN-M1-BG2-NNNN in precision couplings?

It supports backlash-free clamping or shrink-fit couplers for minimizing runout and torsional compliance. It helps preserve encoder-referenced accuracy when reversing under cyclic loads or executing contouring profiles.

How does the B-side power connector on MSK101C-0450-FN-M1-BG2-NNNN influence cabinet and cable routing?

It allows motor leads to exit away from load-side tooling for reducing bending stress and EMI coupling into feedback lines. It eases hygienic or confined layouts by separating power and encoder harness paths.

Common Misspellings

Internal Product Review

The MSK101C-0450-FN-M1-BG2-NNNN motor from Bosch is presented in an IP65 protective housing. It uses liquid cooling and its frame size is 101 C-length.
