The Bosch Rexroth Indramat MSM031B-0300-NN-M5-MH0 from the MSM IndraDyn S Synchronous Motors series is a high-precision Synchronous Motor designed for compact industrial automation. With a motor size 031 frame and a motor length B, this unit delivers a rated power of 0.2 kW at a nominal speed of 3000 RPM and sustains a continuous torque at standstill of 0.64 Nm. Engineered for dynamic performance, it reaches a peak torque of 1.91 Nm and accelerates up to 5000 RPM under transient loads. The winding code 0300 and precision-balanced rotor optimize efficiency and reduce vibration for smooth operation. Natural convection cooling ensures reliable thermal management without auxiliary fans, while a rugged IP54 protection rating (housing) and IP40 protection rating (shaft) safeguard internal components from contaminants. The motor features a plain shaft design with no shaft seal and no holding brake, simplifying maintenance and reducing downtime. Under peak conditions, it draws a peak current of 4.9 A and exhibits a winding resistance of 6.10 Ohms at 20 °C, ensuring predictable thermal characteristics. Compact and lightweight, the MSM031B-0300-NN-M5-MH0 integrates seamlessly into rotary indexing tables, conveyor systems, and collaborative robots where precision and robustness are critical. Its standardized mounting flange and keyway allow straightforward retrofit into existing assemblies, while the absence of an integrated brake reduces inertia and enhances response. As part of the Bosch Rexroth Indramat MSM family, this motor benefits from comprehensive compatibility with industry-standard drives and easy commissioning via centralized parameter sets.
