MHD112B-058-PG0-RN

The MHD112B-058-PG0-RN is a high-performance industrial Product Type within the renowned MHD Synchronous Motors series from Bosch Rexroth Indramat. This robust servo motor features a Motor Size of 112 and a corresponding Flange size of 192 mm, ensuring compatibility with standard industrial mounting interfaces. The motor’s Centering diameter of 130 mm and Shaft Design as a plain shaft deliver precise alignment and simplified coupling to downstream components. With a Winding Code of 058, the MHD112B-058-PG0-RN offers consistent thermal characteristics and optimized heat dissipation. Its Housing Cooling Type of liquid cooling further enhances continuous operation under demanding loads while maintaining a compact form factor. This configuration supports secure installation in confined machine enclosures without compromising performance or accessibility.

Performance is defined by a rated input current of 27.5 A, generating a rated output torque of 33.1 Nm and a continuous torque at standstill of 28.0 Nm. The motor delivers a rated power output of 11.0 kW when supplied with a nominal input voltage of 251 V at 187 Hz, providing rapid acceleration and smooth torque delivery across the speed range. Integrated digital servo feedback with an Encoder Type featuring a multiturn, absolute position detection system (>4096 revolutions) ensures micron-level positioning repeatability. The combination of precision encoder feedback and stable coil design minimizes torque ripple, resulting in quiet, efficient operation. This motor supports high dynamic response in advanced motion control applications, yielding responsive performance even under variable load conditions.

Engineered for industrial reliability, the MHD112B-058-PG0-RN operates without a holding brake (Holding Brake: without holding brake) and incorporates a robust Shaft Seal to protect internal bearings from contaminants. Thermal regulation is achieved through natural convection with an option for an external air blower to augment surface cooling in high-duty cycles. Electrical integration is simplified via a right-oriented Power Connection Direction and a standardized Power Connection Type power connector, streamlining cable routing in complex machinery. Its Motor Length designation ‘B’ enables direct replacement of legacy units within the same envelope while ensuring consistent mechanical coupling. The motor’s modular design, combined with standardized mounting dimensions and built-in encoder feedback, makes it ideal for servo-driven conveyors, robotic actuators, printing presses, and other precision automation systems requiring high duty cycles and tight positional control.
