Product Description:
The MSK101D-0300-NN-S1-BP0-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat and supplied within the MSK IndraDyn S Synchronous Motors series. As a permanent-magnet AC motor, it drives automated tooling, gantries, and transfer systems where coordinated motion and highly repeatable positioning are required. The unit integrates with Rexroth drive controllers to deliver torque directly to mechanical loads, forming the electromechanical link between servo amplifiers and moving machine elements across diverse industrial automation cells.
Heat generated during operation is removed by natural convection, so no external fan or liquid circuit is necessary and cabinet airflow must be considered during system layout. The power terminations are located on the B-Side, permitting cable routing away from the encoder housing and reducing electromagnetic coupling. A shaft with keyway delivers positive mechanical locking to pulleys or couplings, simplifying alignment during assembly. Stopping torque is not maintained internally because the motor is supplied without a holding brake; any static load must be secured by the drive or external clamping. Electrical behavior is defined by Winding Code 0300, which fixes coil resistance and inductance for compatibility with standard MSK drives. Additional construction information includes motor size 101, length variant D, and the standard housing design, all of which set the physical envelope and mounting face.
Feedback precision relies on a Hiperface serial interface that communicates absolute position data to the drive. The sensing element is an Optical encoder built on 128 graduated tracks, so one mechanical revolution generates 128 signal periods, allowing fine interpolation inside the controller. Because the encoder is Singleturn, it reports position within one revolution and the machine controller must provide multi-turn tracking when required. The chosen resolution supports smooth velocity loops and accurate synchronization with adjacent axes, especially in packaging or pick-and-place duties referenced in the first paragraph. By combining this feedback system with the convection-cooled frame and keyed shaft, the motor offers deterministic motion performance without added thermal or mechanical complexity.
