Product Description:

The MSK101D-0300-NN-S1-AG3-NNNN is manufactured by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. It serves as a synchronous servo motor that converts electrical energy into controlled torque and speed for positioning axes and feed drives in factory automation. This type of motor is used where accurate speed regulation and repeatable positioning are required during continuous machine operation. The unit uses Hiperface feedback, so the connected drive receives precise position data for commutation and closed-loop motion control.

This model relies on natural convection to remove heat from the stator housing, so surrounding airflow must circulate freely around the frame. Its size code is 101, which indicates the housing diameter and torque class, while the D length extends the magnetic stack for higher power in the same cross-section. The feedback sensor generates 128 signal periods per revolution, giving the drive accurate angle data during operation. An electrically released holding brake provides 120 Nm of static torque to hold vertical loads when power is removed. Winding code 0300 matches the electrical characteristics expected by compatible IndraDrive controllers.

Mechanically, the motor keeps the standard housing, and its plain shaft is suitable for press-fit couplings or shrink disks without key seats. Power enters through the A-side connector, which keeps the feedback connection on the opposite face to reduce interference and can simplify cable routing in compact equipment. The motor uses single-turn feedback, so the reported position resets after each revolution and a reference move is needed when absolute multi-turn position data is required. This arrangement reduces internal memory components while preserving the position resolution needed for controlled servo operation.
