MSK101D-0300-NN-M2-BG2-RNNN
MSK IndraDyn S Synchronous Motors
The MSK101D-0300-NN-M2-BG2-RNNN from Bosch Rexroth Indramat features a plain shaft and an electrically-released holding brake. Part of the MSK IndraDyn S Synchronous Motors series, it delivers 160 Nm max torque and uses a rated speed code of 0300. This IndraDyn S servomotor utilizes natural convection cooling and requires cooling FN.
It includes an optical multiturn absolute encoder with EnDat2.1 interface and 2048 signal periods. Continuous torque at standstill is 57 Nm. Winding inductivity measures 3200 mH.

Frequently Asked Questions
What is the effect of the 3200 mH winding inductance on drive performance?
A high inductance smooths current ripple and reduces torque ripple, but slows current loop response, so your drive needs to be tuned for slower dynamics.
What considerations apply to installing the electrically-released holding brake?
The brake must be energized (powered) to release, so control logic must supply 24 V DC reliably, and mechanical mounting must handle added inertia and alignment.
How does the motor’s max torque versus continuous torque ratio influence sizing?
You get a surge torque headroom (160 Nm vs 57 Nm continuous), but frequent operation near peak shortens thermal life—size so most duty stays under 60 % of max.
How does the EnDat 2.1 multi-turn optical encoder (2048 periods) benefit precision applications?
It provides absolute position feedback across multiple revolutions with fine resolution, enabling accurate homing and servo synchronization without needing reference runs.
What load forces (radial/axial) can the motor shaft tolerate?
It allows up to ~500 N axial load and limited radial force as per the bearing specs—exceeding these will shorten bearing life.
