MSK100A-0450-NN-M2-BG0-RNNN
MSK IndraDyn S Synchronous Motors
The MSK100A-0450-NN-M2-BG0-RNNN, Bosch Rexroth Indramat, MSK IndraDyn S Synchronous Motors offers precision motion in a robust servomotor package tailored for high-demand industrial applications. It features a compact Motor Size: 100 footprint and a configurable Motor Length: A housing optimized for increased concentricity. Designed without compromise, this Product Type: IndraDyn S Synchronous Servomotor integrates seamlessly into multi-axis systems requiring accurate speed and position control. The motor’s Design: Increased concentricity underpins smooth operation and minimal vibration, even under rapid acceleration cycles.
This servomotor employs efficient Cooling: Natural convection to maintain thermal stability without auxiliary fans, reducing maintenance points and noise. At standstill and 100 K, it delivers a Continuous Torque at Standstill 100 K: 17.0 Nm while drawing only Continuous Current at Standstill 100 K: 13.6 A. Under dynamic load, the unit reaches a Maximum Torque: 54.0 Nm with a Maximum Current: 54.0 A, governed by its robust Winding Inductivity: 7,800 mH. Position feedback is achieved through an Encoder Technology: Optical Encoder Turn Type: Multiturn Absolute sensor, offering Encoder Resolution: 2048 signal periods via an Encoder Interface: EnDat2.1 bus for deterministic control. A plain-shaft configuration (Shaft Type: Plain shaft) and a B-side Power Connector: B-Side simplify mechanical integration and power routing.
Engineers benefit from the motor’s maintenance-free cooling and its compatibility with standard drive controllers, ensuring rapid commissioning and predictable performance. Its plain shaft and compact B-side connection facilitate drop-in replacement in existing arrays, while the increased concentricity design and high-resolution absolute feedback guarantee long-term reliability and repeatable positioning. Ideal for robotics, machine tools, and precision assembly, the MSK100A-0450-NN-M2-BG0-RNNN streamlines system integration and maximizes uptime.

Frequently Asked Questions
How does the “increased concentricity” design improve motion quality on MSK100A-0450-NN-M2-BG0-RNNN?
The shaft/hub runout lowers cogging-related torque ripple and mechanical vibration for enhancing interpolation at micro-increments. It yields cleaner surface finish in CNC axes and steadier camera/gantry trajectories in inspection cells.
Why is natural-convection cooling advantageous on MSK100A-0450-NN-M2-BG0-RNNN, and when would retrofitting fans or liquid cooling help?
The convection avoids fans for reducing particulates, noise and maintenance while maintaining thermal balance at moderate continuous load. For elevated continuous power, Rexroth provides axial/radial blowers and liquid-cooling options to extend duty capability.
How does the optical multiturn EnDat 2.1 encoder (2048 signal periods) in MSK100A-0450-NN-M2-BG0-RNNN aid servo precision?
The EnDat’s synchronous serial link transmits absolute position and parameter data deterministically for supporting stiff velocity/position loops. Its optical multiturn sensing and 2048 periods enables fine interpolation and reliable homing-free startup.
What do the standstill ratings mean for MSK100A-0450-NN-M2-BG0-RNNN (17.0 Nm at 13.6 A, 100 K)?
They specify continuous torque/current at a defined motor temperature risefor guiding thermal sizing in hold/low-speed regimes. It is important to use these with ambient and enclosure conditions to verify duty cycle margin.
What integration benefits come from the plain shaft and B-side power connector on MSK100A-0450-NN-M2-BG0-RNNN?
Its plain shaft simplifies coupling selection and alignment in retrofit shafts or precision hubs. Its standardized Rexroth connectors with IP-rated hardware and defined pinouts streamline cabling, temperature-sensor and brake provisions across MSK sizes.
