Frequently Asked Questions

What distinguishes the S3 encoder option on MSK071C-0200-NN-S3-UG0-NNNN from other variants?

The S3 denotes a single-turn capacitive Hiperface® encoder with 16 signal periods that gives resilient, low-drift absolute position per revolution and solid noise immunity. It simplifies startup homing and maintains accurate commutation even under electrical interference.

How does the rotatable 240° encoder connector aid integration for MSK071C-0200-NN-S3-UG0-NNNN?

The 240° rotatable interface lets installers orient the connector to clear cable ducts, doors or moving axes, reducing bend stress and easing service. Its flexibility improves sealing integrity and routing in tight machine envelopes.

Why choose natural-convection cooling on this IndraDyn S motor instead of forced air or liquid?

Its natural convection eliminates fans and hoses for reducing failure points and contamination risks around food, packaging or woodworking dust. It also keeps the motor footprint cleaner while meeting thermal steady-state needs in moderate load cycles.

How do the 14 Nm continuous standstill torque and 44 Nm peak of MSK071C-0200-NN-S3-UG0-NNNN translate to motion profiles?

The continuous 14 Nm supports holding and low-speed feed forces without thermal overload at 100 K spec conditions. Its 44 Nm peak provides headroom for acceleration bursts, cutter engagements or camming peaks before settling to continuous levels.

For MSK071C-0200-NN-S3-UG0-NNNN, how does winding inductivity (≈19,500 mH) influence drive selection and current control?

Its higher phase inductivity smooths current ripple at the inverter PWM frequency to aid torque linearity and reduces acoustic artifacts. Its drive current loops must be tuned with appropriate bandwidth to avoid phase lag and ensure dynamic stability.

Common Misspellings

Internal Product Review

Bosch Rexroth produces MSK071C-0200-NN-S3-UG0-NNNN as a servomotor that integrates a rotatable 240° connector and includes a capacitive Hiperface single-turn encoder. It relies on natural-convection thermal design and it generates nearly 14 Nm of continuous standstill torque, along with 44 Nm peak torque by utilizing a maximum current of around 23.4 A. It is designed for woodworking, assembly and automotive automation lines where precise torque and speed regulation is needed.
