The Bosch Rexroth Indramat MSK100B-0200-NN-M1-BP2-NNNN from the MSK IndraDyn S Synchronous Motors series is a Standard IndraDyn S Synchronous Servomotor featuring a motor size 100 frame and motor length B, designed for robust performance in demanding automation tasks. It incorporates a shaft with keyway and features an optical multiturn absolute encoder technology with a Hiperface interface and 128 signal periods resolution for high-precision feedback. Continuous torque at standstill is 33.0 Nm with a continuous current of 17.3 A at 100 K, while the maximum torque peaks at 102.0 Nm under a maximum current of 66.2 A. Natural convection Cooling and a B-side Power Connector ensure reliable thermal management and seamless integration into existing drive systems.

The holding brake is electrically-released and delivers a braking torque of 70 Nm for secure position retention during power loss or maintenance. Its Rated Speed Code 0200 supports high-speed applications with precise dynamic control. The wound stator design yields a Winding Inductivity of 7,600 mH optimized for dynamic response and torque ripple minimization. A noted design Constraint prohibits variant length A, ensuring the B-length housing meets mechanical rigidity and heat dissipation requirements.

This MSK Series motor’s combination of precision encoder feedback, robust holding brake, and high-inductivity winding makes it ideal for CNC machines, robotics, and high-performance packaging systems. With its natural convection cooling and B-side Power Connector, the MSK100B-0200-NN-M1-BP2-NNNN delivers maintenance-free, high-dynamics performance in compact installations. Its standardized interface and frame simplify drop-in replacement within the Bosch Rexroth Indramat ecosystem.

Frequently Asked Questions

What encoder scheme is used in MSK100B-0200-NN-M1-BP2-NNNN and why does it matter?

The M1 option integrates an optical multiturn absolute encoder with a Hiperface interface and 128 signal periods for enabling deterministic phase alignment and absolute homing-free start-ups. It improves contouring accuracy, multi-axis synchronization and IndraDrive commissioning.

How does the 7,600 mH stator inductivity in MSK100B-0200-NN-M1-BP2-NNNN affect control dynamics?

The higher phase inductivity filters PWM ripple and reduces torque ripple for easing current-loop tuning at the expense of slightly lower electrical bandwidth. It helps smoother low-speed motion and stable high-resolution contouring with the Hiperface feedback.

What are the environmental and thermal ratings, and what do they imply for installation?

The motor is IP65 with insulation class F and specified for 0…40 °C ambient under natural-convection cooling. It is important to ensure unobstructed airflow and enclosure sealing so contamination and thermal rise remain within rating.

How does the 70 Nm electrically-released holding brake assist vertical axes on MSK100B-0200-NN-M1-BP2-NNNN?

The 24 V brake applies on power-off for supplying 70 Nm to hold loads during e-stop or maintenance. Its engage/disengage times simplify safe-torque-off sequencing. It reduces Z-axis drift risks and complements mechanical counterbalance.

What shaft-load limits apply to MSK100B-0200-NN-M1-BP2-NNNN, and how does that guide belt or pinion selections?

The MSK100 series lists a 500 N maximum axial load and provides speed-dependent radial force curves. It is important to use these with your overhung load calculations and pulley offsets to maintain bearing life.
