Product Description:

The MSK101D-0300-FN-S1-AG0-NNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. Designed for integration into modular industrial drives, it turns electrical power from an inverter into controlled mechanical rotation that positions tooling, conveyor sections, or robotic joints. Standard construction and sealed windings let the unit operate in production lines that demand consistent cycle times and repeatable accuracy.

Its cooling arrangement relies on liquid cooling, so heat is carried away by a circulating coolant rather than ambient air; this permits full continuous torque even when the motor is mounted inside a tight enclosure. Feedback is generated by an optical encoder that combines a Hiperface interface with 128 signal periods of base resolution; when interpolated by the drive, these periods translate into fine incremental angle data for precise velocity regulation. Because the encoder is a single-turn device, absolute position information repeats after one revolution, simplifying homing routines on short-stroke axes. The mechanical end of the rotor uses a plain shaft, and the motor is delivered without a holding brake, so any load-holding duty must be covered by external actuators or drive torque.

The wiring orientation is fixed to the A-side, allowing power leads and coolant hoses to be routed together along a single machine wall for cleaner cabinet layouts. Frame code 101 indicates the stator diameter, while the D length gives the motor a stack depth that balances moment of inertia against continuous power. The motor uses winding code 0300; this selection sets phase resistance and inductance to match medium-voltage IndraDrive supplies and avoids current derating during rapid acceleration. The motor keeps its standard design classification, and its plain shaft facilitates direct coupling with suitable hubs, shrink discs, or belt pulleys as required by the mechanical installation.
