Product Description:

The MSK101E-0300-NN-S1-BG0-NNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. This motor is built for closed-loop industrial axes where compact size, high torque density, and encoder feedback are required. It provides rotational power to automated machinery while allowing precise position control through its integrated encoder. The device follows the standard design layout for the series and is intended for cabinet or open-frame installations.

The motor relies on natural convection as its cooling method, so ambient airflow removes heat without auxiliary fans. Its feedback chain uses a Hiperface interface that transmits absolute position data directly to an IndraDrive controller. The optical sensor offers 128 signal periods per mechanical revolution, and the optical scanning principle helps keep the signal stable under vibration. Because the sensing system is single-turn, absolute position is retained for one full rotation before the count resets, which is sufficient for rotary axes that reference at startup. Motor length code E balances torque output with envelope size, and winding code 0300 matches the stator to drives that supply the required current and back-EMF limits.

The unit is delivered without a holding brake, so external clamping or drive torque must secure stationary loads during power loss. Frame size 101 sets the stator diameter and flange pattern, while the power lead exits on the B-side to keep cable runs clear of the driven shaft. Motion is transferred through a plain shaft that accepts clamp or shrink-fit couplings for backlash-free torque transfer. This arrangement suits medium-inertia packaging, printing, and material-handling axes where accurate velocity and position control are necessary during repeated motion cycles.
