The Bosch Rexroth Indramat MS2S05-C0BTN-IMHG0-NNDNN-NN servo motor from the MS2S Synchronous Servomotors series offers robust performance and precise motion control for industrial automation applications. This compact unit delivers a standstill torque of 7.15 Nm at a thermal rise of 100 K and maintains 6 Nm standstill torque at 60 K, ensuring high static holding power. Equipped with an 18-bit multiturn encoder yielding 65,536 distinguishable rotations, the servo achieves a maximum system accuracy of ±360 arcsec through the ctrlX SENSE interface. Designed and manufactured by Bosch Rexroth Indramat, this model emphasizes durability, reliability, and ease of integration in demanding environments.
In terms of key specifications, the MS2S05 motor features a voltage constant of 56.1 V/1000 min⁻¹ at 20 °C and a winding resistance of 1.27 Ω measured at the same temperature, with a winding inductance of 7.9 mH for smooth dynamic response. The encoder operates on an 8–12 V supply drawing up to 130 mA for feedback and position monitoring. Protection is rated at IP65, safeguarding against dust ingress and low-pressure water jets. The rotor inertia is optimized for rapid acceleration, while the concentricity tolerance of 0.04 mm ensures minimal run-out and high repeatability.
Operationally, the servo motor is designed for ambient temperatures between 0 °C and +40 °C and relative humidity from 5–95 %, with an absolute humidity tolerance of 1–29 g/m³ to address various production environments. The thermal time constant of the winding is 34 s, providing predictable thermal behavior under continuous operation, and the leakage capacitance of the component is 1.5 nF for electromagnetic compliance. Standstill current is rated at 6.9 A at 60 K, supporting stable torque without movement. The motor employs a self-cooling mode and standard deep-groove ball bearings, coated in RAL 9005 black varnish for environmental protection.
System integration is facilitated by the IM B5 (IM 3001) mounting code and a single, rotatable M17 cable connection, streamlining installation in complex machine architectures. The standard flange mounting and the DIN 332 Part 2 centering hole guarantee precise alignment and mechanical stability. Without a holding brake, this MS2S series unit reduces complexity while focusing on synchronous servomotor performance. Ideal target applications include precision conveyors, robotics, packaging machinery, and any industrial automation system requiring high torque density, accurate positioning, and reliable long-term operation.
