Product Description:

The MSK101D-0300-NN-S2-AG0-RNNN synchronous servomotor is produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It serves as a precision drive in factory automation. The motor supplies regulated torque and speed to motion axes that require high cyclic repeatability and accurate feedback, making it suitable for positioning tasks that depend on stable servo response over repeated operating cycles.

Heat dissipation relies on natural convection, so the frame cools through surface exposure without external fans or liquid lines. Rotor and stator alignment follow an increased concentricity design that helps reduce runout and supports smoother velocity profiles during motion. Position data leave the motor over the EnDat2.1 bidirectional digital interface, allowing parameter storage and automatic electronic nameplate reading by the controller. The sensing system uses an optical scanning principle and resolves one mechanical revolution into 2048 signal periods; interpolation inside the drive increases this base count for fine position control and stable commutation. Because the measuring element is single-turn, absolute information is available for one turn, and machine-level referencing is required when travel extends beyond 360 degrees.

The output shaft is a centered, non-keyed plain shaft, which simplifies coupling to backlash-free clamping hubs and supports accurate torque transfer without a keyed connection. Power and brake conductors exit on the motor’s A-side, which sets the cable direction for compact machine layouts and helps keep routing consistent around the drive axis. The stator uses winding code 0300, which sets the current, voltage, and torque characteristics expected by compatible IndraDrive amplifiers. Frame designation 101 corresponds to the motor size, and length class D extends the active stack for higher continuous torque without changing the mounting interface. The unit is supplied without a holding brake, so external locking devices or continuous drive torque must secure vertical loads when power is removed.
