MSK100A-0450-NN-S1-BP1-NNNN
MSK IndraDyn S Synchronous Motors
The Bosch Rexroth Indramat MSK100A-0450-NN-S1-BP1-NNNN is part of the MSK IndraDyn S Synchronous Motors series and delivers reliable performance as a IndraDyn S Synchronous Servomotor. This compact servomotor features natural convection cooling and an optical singleturn encoder with Hiperface interface, offering a resolution of 128 signal periods. With a continuous torque at standstill of 17.0 Nm at 100 K and a maximum torque of 54.0 Nm, it is engineered for precise motion control in demanding industrial applications.
In detailed operation, the motor’s winding code 0450 yields a winding inductivity of 7,800 mH, supporting smooth current transitions. The continuous current at standstill is 13.6 A, rising to a maximum current of 54.0 A for peak performance. The integrated holding brake, with electrically released functionality, provides a holding torque of 32 Nm to secure shafts during power loss. The motor’s shaft includes a keyway per DIN 6885-1 for form-fitting connections. Its four pole pairs enable agile response up to a maximum speed of 6,000 rpm, ensuring rapid acceleration and deceleration.
Durability and compatibility are ensured by the sealed housing with an ingress protection rating of IP 65 (EN 60529), which allows operation in harsh environments. The black RAL 9005 2K epoxy resin coating based on epoxy polyamide resin provides chemical resistance to dilute acids, alkalis, mineral oils, sewage, and water. Power is delivered via the standard B-Side connector. The motor’s robust design and advanced encoder memory, which stores motor type and control loop parameters, reduce startup time and simplify commissioning. Overall, the MSK100A-0450-NN-S1-BP1-NNNN offers high torque density, efficient cooling, and reliable operation, making it ideal for precision automation and continuous industrial use.

Frequently Asked Questions
How does the singleturn Hiperface encoder (128 signal periods) influence positioning accuracy on the MSK100A-0450-NN-S1-BP1-NNNN?
It provides absolute position within one revolution and fine interpolation for smooth commutation for improving low-speed stability and repeatability. It combined with stored motor parameters, the drive auto-configures feedback for rapid start-up and consistent alignment.
What does winding code 0450 (7,800 mH inductivity) imply for current ripple and servo dynamics?
The higher inductivity filters PWM ripple and supports smoother current transitions for aiding precise torque control under stiff loops. It slightly narrows electrical bandwidth, which the drive compensates with tuning to preserve response around the 13.6 A continuous-current operating point.
Why is an electrically released 32 Nm holding brake used in the MSK100A-0450-NN-S1-BP1-NNNN?
The spring-applied brake clamps the shaft for securing vertical or safety-critical axes against drift. On re-energization it releases electrically for enabling controlled homing without back-driving and simplifying functional-safety strategies.
What protections do IP65 sealing and the black RAL 9005 2K epoxy polyamide coating provide in oily or alkaline environments?
The IP65 resists dust ingress and water jets for supporting operation in wash-down or chip-laden areas. Its specified coating exhibits chemical resistance to dilute acids, alkalis, mineral oils and sewage that extends finish life with limited protection versus some solvents.
How do four pole pairs and a 6,000 rpm ceiling shape torque and speed behavior on MSK100A-0450-NN-S1-BP1-NNNN?
The eight magnetic poles give finer electrical angle resolution for improving smoothness and control authority at low speed. Its 6,000 rpm mechanical limit balances torque density with rotor stress for enabling rapid acceleration while staying within drive frequency and bearing constraints.
