Frequently Asked Questions
How does the 3.3 mH winding inductivity in MSK101C-0450-NN-M1-BG2-NNNN influence current slew rates and torque ripple?
ts higher inductivity smooths phase-current transitions for reducing ripple and cogging-induced speed modulation under tight velocity loops. It benefits precision contouring and servo stiffness in multi-axis machines operating at variable loads.
What continuous-duty capability is available at 100 K, and when is “Cooling FN” advisable on MSK101C-0450-NN-M1-BG2-NNNN?
It delivers 36.5 Nm with 28.6 A that is suitable for moderate thermal loading and intermittent cycles. It is important to add forced-ventilation (FN) blowers where sustained torque density is required to avoid thermal limiting and increase continuous output.
What dynamic headroom do 113 A (Imax) and 110 Nm (Mmax) give MSK101C-0450-NN-M1-BG2-NNNN?
The high peak current/torque margins support fast acceleration and transient load rejection without saturating the drive. It combined with the rotor inertia listed for 101C frames yields responsive yet controllable axis behavior.
Why specify a Hiperface multiturn optical encoder (128 signal periods) on this motor?
The Hiperface multiturn encoders provide absolute position over multiple revolutions and fine sine/cosine interpolation from 128 periods per rev for enabling accurate commutation and low-jitter speed control. It simplifies homing and improves restart reliability after e-stops.
What bearing lifetime should users expect under prescribed load limits?
The IndraDyn S motors are calculated for an L10h bearing life of ~30,000 operating hours when radial/axial loads remain within catalog limits. Its proper coupling alignment and load modeling are essential to achieve this figure.

Internal Product Review
The Indramat’s MSK101C-0450-NN-M1-BG2-NNNN motor is constructed in a size-101 and length-C format. It relies on passive surface heat dissipation and uses a Hiperface multiturn encoder for feedback precision. This motor is rated for 36.5 Nm at 28.6 A (100 K) with 110 Nm peak. It targets packaging, printing, and metal-forming assemblies with is plain shaft and 70 Nm brake for simplified coupling and load security.
