MHD112B-058-PG1-BN
MHD Synchronous Motors
The Bosch Rexroth Indramat MHD112B-058-PG1-BN from the MHD Synchronous Motors series delivers precision motion control with a motor size 112 frame and liquid cooling via its housing cooling type. This servo motor features a digital servo feedback w/ integrated encoder and absolute (>4096 revolutions) position detection for high-resolution accuracy. Equipped with a 22.0 Nm holding brake torque holding brake and a plain shaft design with shaft seal, it ensures secure stops and reliable uptime. The compact B motor length and 192 mm flange size conserve space without sacrificing performance.
Built to handle continuous loads, the motor provides 28.0 Nm continuous torque at standstill and integrates a 058 winding code for optimized thermal management. Power is routed efficiently through an output connector with the power connection direction to side B, simplifying cable routing in dense installations. The robust 130 mm centering diameter guarantees stable mounting and repeatable alignment in compact drive cabinets. A rugged housing and precision-balanced rotor support smooth operation at high speeds and under variable loads.
Installation and maintenance are streamlined by the motor’s standardized dimensions and built-in feedback system. Designed for demanding industrial environments, the MHD112B-058-PG1-BN reduces commissioning time and enhances system reliability. Its advanced feature set makes it ideal for applications requiring precise positioning, cyclic motion, and extended duty cycles.

Frequently Asked Questions
How does the MHD112B-058-PG1-BN ensure safety during sudden power-off conditions?
It includes a 22.0 Nm holding brake to lock the shaft during shutdowns. This prevents unplanned motion and secures vertically loaded systems.
Is high-resolution positioning possible without homing after each startup?
The motor integrates a digital feedback encoder with absolute position detection over 4096 revolutions. This allows precise tracking with persistent position memory.
How is heat efficiently managed during high-torque, continuous-duty operation?
Its 058 winding code and liquid-cooled housing work together to stabilize internal temperature. This enables reliable torque output under thermal stress.
Can this motor be easily installed in space-constrained or panel-mounted systems?
Yes, the compact B-length frame and side B power connector simplify integration. It supports dense layouts by minimizing cable intrusion and installation depth.
What supports accurate mechanical alignment in high-speed or vibration-prone systems?
A 130 mm centering diameter and 192 mm flange size ensure repeatable, stable mounting. This promotes long-term reliability in modular machine frames.
