Product Description:

The MSK100D-0300-NN-S2-BP2-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It supplies closed-loop torque and velocity control for positioning tables, packaging lines, and pick-and-place robots where fast dynamic response and compact installation are important. In servo-driven machinery, it converts current commands into controlled rotary motion for indexing systems, feeders, and synchronized transfer mechanisms. Integrated feedback and an electrically released holding brake help the motor maintain load position when power is removed, which is useful on vertical or suspended axes.

The motor has a size of 100, making it suitable for medium-power axes. It uses the D motor length, which is the longest stator length in this frame and supports higher continuous power without increasing shaft overhang. Cooling is handled by natural convection, which removes heat without a blower and avoids added fan noise. Power enters through a B-side power connector, keeping the main power connection separate from the feedback interface and helping with cable routing. The motor uses a shaft with a keyway for positive coupling engagement. Winding code 0300 identifies the electrical winding arrangement, and the magnetic stack is ground for improved concentricity to help reduce cogging torque. The electrically released brake provides 70 Nm of static holding torque.

Position feedback uses EnDat 2.1 serial communication for fast data exchange between the encoder and the servo drive. The encoder delivers 2048 signal periods per revolution, and its optical sensing method avoids mechanical wear on the code track. A single-turn circuit stores the absolute position within one revolution, so the motor can report shaft position immediately after startup without a homing move. This feedback arrangement supports precise commutation, stable low-speed operation, and accurate position control across the operating range.
