MSK101D-0300-NN-M2-AP2-RNNN
MSK IndraDyn S Synchronous Motors
The Bosch Rexroth Indramat MSK101D-0300-NN-M2-AP2-RNNN from the MSK IndraDyn S Synchronous Motors series is a high-performance IndraDyn S Synchronous Servomotor engineered for precision drive applications. This motor features a motor size 101 frame with a compact motor length D and a rated speed code 0300 that delivers reliable speed control up to its defined synchronous revolutions. Designed with increased concentricity, the unit ensures optimal rotor alignment for reduced vibration and enhanced bearing life. The robust shaft with keyway provides a secure mechanical interface for demanding automation tasks.
Built to integrate seamlessly into modern drive systems, the MSK101D-0300-NN-M2-AP2-RNNN employs natural convection for passive thermal management and carries a constraint: Requires Cooling FN label for installations with auxiliary cooling requirements. The motor is equipped with an optical encoder technology offering a multiturn absolute encoder turn type and EnDat2.1 interface compatibility. With an encoder resolution of 2048 signal periods, the setup guarantees high-fidelity position feedback for closed-loop control. Power connections are handled via an A-Side power connector for streamlined wiring, and the integrated electrically-released holding brake delivers a holding brake torque of 70 Nm to secure the load when de-energized.
Electrical performance is tailored for both dynamic and static loads: the motor provides a continuous current at standstill of 34.9 A and a correspondingly high continuous torque at standstill of 57.0 Nm at 100 K winding temperature. When higher demands arise, the unit sustains a maximum current of 137.7 A and a maximum torque of 160.0 Nm to handle transient peak loads. The substantial winding inductivity of 3,200 mH supports smooth current transitions and minimizes torque ripple under variable frequency operation. Together, these characteristics make this servomotor an ideal choice for robotics, packaging machinery, and precision positioning systems requiring exceptional torque density and accuracy.

Frequently Asked Questions
How critical is concentricity improvement for vibration and bearing life?
Higher concentricity reduces unbalanced forces at high speed, thereby lowering vibration, mechanical stress, and bearing fatigue over long operational life.
In closed-loop control, what does 2,048 signal periods per revolution imply for positioning resolution?
That quantization gives about 0.175 ° per encoder period, so motion control interpolation or averaging is needed to achieve sub-arcminute precision.
What must be considered when coupling the motor’s keyed shaft in a high-reversal application?
The key coupling introduces stress concentrations; in frequent direction changes, clamping hubs or zero-backlash couplers are preferred to avoid keyway fatigue or shaft damage.
hat installation constraints arise from the requirement “Requires Cooling FN”?
You must provide either forced-air or liquid cooling attachments (FN version) when ambient conditions exceed limits or duty cycles cause excessive heat buildup.
How does the motor interface electrically with drives and feedback systems?
Power is delivered via the A-side connector with integrated temperature sensor and brake lines, while the EnDat 2.1 multiturn absolute encoder provides deterministic absolute position feedback.
