MSK101C-0450-NN-M1-BP0-NNNN
MSK IndraDyn S Synchronous Motors
The MSK101C-0450-NN-M1-BP0-NNNN from Bosch Rexroth Indramat belongs to the MSK IndraDyn S Synchronous Motors series. This IndraDyn S Synchronous Servomotor delivers high-precision motion control and rapid dynamic response across industrial automation tasks. Engineered with an optical multiturn absolute encoder, it ensures accurate position feedback and repeatability. Its standard design and shaft with keyway facilitate straightforward integration into existing drive architectures.
Featuring natural convection cooling and a durable B-Side power connector, this motor balances thermal management with serviceability. The motor length code is C, and the compact 101 size minimizes footprint without sacrificing performance. Encoder specifications include 128 signal periods resolution, multiturn absolute turn type, and a reliable Hiperface interface. Electrical characteristics span a continuous current at standstill of 28.6 A and continuous torque at standstill of 36.5 Nm at 100 K, delivering strong holding capacity even without a holding brake. It supports a maximum current of 113.0 A and develops up to 110.0 Nm of torque during peak load conditions. A winding inductivity of 3,300 mH optimizes the motor’s electromagnetic compatibility and smooth torque delivery.

Frequently Asked Questions
What integration considerations apply for the “shaft with keyway” configuration on this MSK101C variant?
Its keyed solid shaft simplifies rigid and pulley couplings, It proper key fit and hub tolerance is important to avoid fretting. It aligned coupling minimizes radial/axial loads and permissible shaft loads.
How should I interpret the torque/current limits on MSK101C-0450-NN-M1-BP0-NNNN for a cyclic profile?
It is recommended to use 36.5 Nm at 100 K for continuous segments, while 110 Nm and 113 A define short-time peaks subject to thermal models and drive current limits.
What role does the 3,300 mH winding inductivity play in MSK101C-0450-NN-M1-BP0-NNNN behavior?
The higher phase inductivity filters current ripple and supports smoother torque production to aid low-speed contouring and better drive current control. It can also help with longer cable runs by damping high-frequency components in PWM drive outputs.
Why is the B-side power connector advantageous in tight machine envelopes?
The routing power on the B-side can shorten cable runs that reduces bend-radius stress and separate power from feedback cabling to mitigate EMI. It also improves service access when the A-side faces a bulkhead or guarding.
How does natural-convection cooling affect continuous duty for MSK101C-0450-NN-M1-BP0-NNNN?
The passive cooling avoids fan maintenance and acoustic noise but requires adequate mounting surface and airflow to dissipate heat. Its use at 100 K standstill ratings (28.6 A, 36.5 Nm) is important for sizing under continuous thermal conditions noted in your spec.
