Product Description:

The MSK101D-0300-FN-M2-RG0-RNNN is manufactured by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. It is a servo motor intended for closed-loop position and speed control in automated machinery. The design supports precise torque delivery and rapid feedback for coordinated multi-axis motion. That combination is useful in systems that rely on stable axis response during acceleration, positioning, and speed changes.

The motor body is built to Motor size 101 and uses winding code 0300, and together these values indicate its electromagnetic loading and current demand. Internal channels support liquid cooling, so heat is removed directly from the stator jacket and continuous output can be increased without enlarging the frame. This cooling method helps manage thermal load in compact machine layouts where air circulation may be limited. Rotor machining follows an increased-concentricity design that reduces runout and helps maintain tight coupling with high-precision gearheads. A right-side power connector can simplify cable routing when access is limited on one side of the machine base. The housing uses length code D, which provides additional iron for higher rated torque. Mechanical output is delivered through a plain shaft, which accepts custom couplings and keeps torsional backlash at zero when clamped.

For feedback, the motor carries an encoder that communicates through the EnDat 2.1 interface. This digital link transfers absolute position data to the controller and supports automatic parameter transfer. The scanning disk resolves 2048 signal periods per revolution with multiturn absolute tracking, so the controller knows shaft angle and turn count immediately after power-up. Immediate position availability can reduce startup movement when the axis must resume from a known location. Sensing is based on an optical path rather than magnetic tracks, which supports accurate interpolation at high speeds. The unit is supplied without a holding brake, making it suitable for applications where static locking is handled by external clamping devices or by servo torque.
