Product Description:

The MSK101D-0300-NN-S2-BP2-RNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In industrial automation, the unit provides precise rotational power for drive axes that require fast response and tight position control, integrating easily with Rexroth inverters and multi-axis controllers. Power is connected through a B-side connector, which keeps cabling on one face of the machine.

A protection rating of IP65 shields the housing from dust and low-pressure water jets, so the motor can be mounted directly on machinery without additional enclosures. Thermal management is passive, and the stator windings release heat through natural convection; the FN cooling code indicates that no external blower or liquid circuit is required. Motion feedback uses an optical encoder with EnDat2.1 communication and 2048 signal periods per revolution, giving the drive fine incremental position data. An electrically released holding brake delivers 70 Nm of static torque to secure vertical loads during power loss. Winding code 0300 sets the voltage, current, and torque constants, while the frame is motor size 101 with length designation D, which helps match continuous output to the duty cycle. The motor operates reliably in ambient air from 0–40 °C without derating.

Bosch Rexroth specifies increased concentricity in the rotor design for smoother torque ripple, and the output is transmitted through a shaft with keyway that simplifies coupling to timing pulleys or gearboxes. The encoder has single-turn tracking and returns absolute angular position within one revolution, supporting quick homing after controller resets. Class-F insulation rated to class 155 permits higher winding temperatures and supports service life under cyclic peak loads.
