Product Description:

The MSK101D-0300-NN-S2-AG2-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. In industrial automation, this motor supplies closed-loop torque and velocity so that controllers can drive packaging stations, material-handling gantries, or machine-tool spindles with repeatable accuracy. It is intended for servo axes that need stable response during acceleration, deceleration, and continuous speed regulation. That operating profile suits transfer axes and indexing applications where smooth motion and repeatable stopping are important.

This model uses natural convection, so the FN cooling arrangement requires unobstructed airflow along the housing fins. Position feedback comes from a single-turn optical encoder that communicates through EnDat 2.1, and the system provides 2048 signal periods per mechanical revolution for fine incremental resolution. An optical reading head tracks the shaft angle without contact, which helps reduce wear and supports consistent feedback quality over long operating periods. During power loss, an electrically released brake supplies 70 Nm of holding torque, which can keep a vertical or suspended axis from drifting when drive power is removed.

The rotor and flange are manufactured to an increased concentricity tolerance, which helps reduce radial runout when the motor is coupled to precision gear stages. Frame size 101 corresponds to the stator diameter, and it is paired with winding code 0300 for the required current and torque characteristics in this motor size. Power enters on the A-side of the housing, which helps keep cable routing clear in compact machine layouts. The D motor length places the unit in a medium torque range for the 101 frame. The motor also uses a plain shaft, so it is intended for clamp-style hubs or shrink-fit couplings rather than keyed connections.
