Product Description:
The MSK100D-0300-NN-S1-BP2-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. It converts drive current into controlled torque and speed for positioning axes and cyclic motion in automated machinery. It is intended for servo-controlled axes where the drive must coordinate rapid indexing moves, dwell periods, and repeated direction changes without losing positional accuracy. Its standard mechanical design and shaft with a keyway make the unit suitable for direct coupling to precision gearboxes or belt drives in packaging equipment, material-handling cells, and general factory automation.
Heat is removed solely by natural convection, so installation must allow airflow around the stator housing. Feedback is provided through a Hiperface interface that carries both position data and electronic motor data to the drive controller. The embedded encoder delivers 128 signal periods per revolution, and its optical scanning method supports repeatable feedback while resisting magnetic interference. Because the encoder is a single-turn device, absolute position is retained for one revolution and then resets, which suits axes that re-home at power-up. The motor uses length D and follows the standard housing design of the series.
The electrically released holding brake produces 70 Nm of static torque, allowing the axis to maintain position during emergency stops or power loss without drive current. Power is supplied through a connector mounted on side B, which can simplify cable routing when space behind the motor is limited. The brake supports stationary holding, while motion control during operation depends on the matched servo drive and feedback loop. The stator core corresponds to frame size 100, giving the motor the thermal mass required for continuous operation with natural convection. The motor also uses winding code 0300, which matches the electromagnetic characteristics intended for this frame size.
