Product Description:

The MSK101D-0300-FN-M1-AP2-NNNN servomotor belongs to the MSK IndraDyn S Synchronous Motors series from Bosch Rexroth Indramat. As a synchronous servomotor, it converts drive-controller current into controlled mechanical power for positioning and velocity loops in automated machinery. Its frame and winding layout support closed-loop motion tasks such as gantry drives, tool spindles, and material-feed axes where fast response and repeatable accuracy are required. It also integrates an absolute feedback device so the axis can start with immediate positional awareness after power is restored.

Thermal management is handled by liquid cooling, and the FN requirement means the stator must be connected to a closed coolant circuit before the drive is energized to keep winding temperatures stable during continuous duty. The electrically released holding brake provides a peak holding torque of 70 Nm, which helps secure vertical loads when power is removed. Command and diagnostic data pass through the Hiperface interface, and the scanning head generates 128 signal periods per revolution for fine interpolation. Because the scale is optical, feedback accuracy is not affected by magnetic stray fields. The motor has a frame size of 101, and the D length code keeps the housing within the intended installation envelope.

The feedback module is a multiturn absolute device, so the encoder stores mechanical revolutions in nonvolatile memory and can recall position after a mains interruption. Mechanical coupling is provided by a shaft with a keyway, which supports positive drive engagement with keyed pulleys or couplings. Winding code 0300 sets the electrical values expected by the matching drive controller. A power connector on the A-side helps simplify cable routing, and the housing follows the standard mechanical design.
