The MSK101D-0300-NN-M1-BP3-NNNN servomotor from Bosch Rexroth Indramat is part of the MSK IndraDyn S Synchronous Motors series. It offers 160.0 Nm peak torque and 57.0 Nm continuous torque at standstill, plus a 120 Nm electrically-released holding brake. The motor uses an optical multiturn absolute encoder with Hiperface interface and is cooled by natural convection. It features a keyed shaft with seal and a B-side power connector.

Frequently Asked Questions

What ingress protection and environment limits should I plan for on the line?

MSK motors are typically IP65—dust-tight and resistant to low-pressure water jets—but not immersion-rated or for caustic washdown without extra measures. Standard ratings cite 0–40 °C ambient and ≤1000 m altitude; derate outside these bounds.

Which drives natively support this Hiperface-equipped MSK motor?

Rexroth IndraDrive C/HCS and ctrlX DRIVE support MSK motors with Hiperface feedback; the motor’s electronic nameplate streamlines parameter loading and overload settings. Match current/voltage to the drive’s inverter rating using IndraSize

What installation practices matter most for long encoder cable runs in multi-axis cells?

Keep feedback and power cables separated, maintain shield 360° terminations at both ends, and observe the controller’s max encoder frequency to prevent signal distortion. Hiperface’s relatively low transmission frequency helps preserve signal integrity over longer lengths

For robotics, packaging, or metal forming, how should I size around the 57 Nm continuous / 160 Nm peak torque?

Use application peak-to-RMS torque ratios and thermal time constants from the MSK data to ensure peaks don’t overheat during short cycles; validate with drive current limits. Pair with appropriate gearing and brake torque when holding vertical loads or precise dwell positions.

What maintenance considerations extend service life in 24/7 B2B production?

Plan periodic inspection of shaft seals, bearings, and connectors; service intervals depend on duty, speed, and environment. Use Bosch Rexroth service guidelines for wear-part replacement.
