Product Description:
The MSK101D-0300-NN-M2-AG0-RNNN is produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. This AC servomotor has size 101 and D length, and it is used for precise torque and speed control on indexing tables, gantry axes, and packaging machinery. By synchronizing its stator field with the drive frequency, it converts electrical energy into controlled mechanical rotation and supports tight position loops in automated cells. These applications benefit from controlled acceleration, repeatable stopping, and stable low-speed behavior during indexing and transfer moves. The motor uses a plain shaft for direct coupling, and winding code 0300 matches the electrical values expected by compatible IndraDrive amplifiers.
Thermal management relies on natural convection, so airflow around the housing removes losses without fans or liquid circuits. The rotor and housing are machined to an increased concentricity tolerance, which helps reduce radial runout during high-speed cycles and supports stable bearing operation. For feedback, an EnDat2.1 serial interface is fitted, and its measuring module provides 2048 signal periods per mechanical revolution. Combined with the optical scanning principle, the multi-turn absolute encoder can capture up to 4096 turns of position data, allowing fine interpolation inside the controller and smooth motion at low speed. That feedback format gives the drive immediate position data after startup and supports accurate commutation throughout the speed range.
The power connector is mounted on the A-side, which can simplify cable routing in compact cabinets and along crowded machine frames. The motor is supplied without a holding brake, so position retention during power-off conditions must come from external clamping or drive-generated torque. The housing is rated IP65, which helps keep out dust and water jets, and the permitted ambient operating range is 0 to 40 °C. The insulation system meets class 155, supporting continuous thermal loading while protecting the winding system. This arrangement is useful where cabinet airflow is limited and external cooling hardware is not desired.
Frequently Asked Questions about MSK101D-0300-NN-M2-AG0-RNNN:

A: This model features a plain shaft design, which provides a smooth interface for coupling with compatible machinery.
Q: What kind of encoder and resolution are equipped on the MSK101D-0300-NN-M2-AG0-RNNN?
A: The encoder uses optical technology with a resolution of 2048 signal periods, allowing for precise position feedback.
Q: How is the MSK101D-0300-NN-M2-AG0-RNNN motor cooled during operation?
A: The MSK101D-0300-NN-M2-AG0-RNNN operates with natural convection cooling, eliminating the need for an external fan.
Q: Does the MSK101D-0300-NN-M2-AG0-RNNN include a holding brake?
A: This motor is manufactured without a holding brake, so it does not provide braking functionality when power is removed.
Q: What is the protection rating of the MSK101D-0300-NN-M2-AG0-RNNN motor?
A: The protection rating of IP65 means this servomotor is dust tight and protected against low pressure water jets from any direction.
