Product Description:

The MSK101D-0300-FN-M2-BG2-RNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat and supplied within the MSK IndraDyn S Synchronous Motors series. The unit converts drive-inverter output into precise rotary motion for positioning tasks in automated machinery, packaging stations, and material-handling lines. Its construction supports closed-loop control so that velocity, angle, and torque follow programmed trajectories, making it a core drive element in CNC cells and robotics. The motor integrates an optical encoder and an electrically released brake to hold axes during idle conditions or emergency stops.

A forced-circulation cooling jacket carries coolant through the stator; this liquid cooling method removes heat independently of ambient air so the motor can sustain rated torque in sealed machine frames. Position feedback is transmitted over the EnDat2.1 digital interface, allowing serial transfer of absolute position and diagnostic data to the drive. Inside the scanning head, an optical grating generates 2048 signal periods, and controller interpolation provides fine angular resolution for small positioning moves. The encoder uses multi-turn absolute position tracking, eliminating homing cycles after power loss. An integrated brake provides 70 Nm of holding torque and releases electrically, keeping vertical or load-bearing axes secure when drive power is removed.

The motor has motor length D, which pairs the 0300 winding with an iron stack that balances thermal capacity and peak dynamics. It uses motor size 101, giving a shaft center height suitable for mid-range gantry and press drives. The output uses a plain shaft without a keyway, which simplifies coupling alignment and supports low runout. Power is routed through a B-side connector so cables exit opposite the feedback port, easing cable segregation in tight cabinets.
