MHD112B-035-PG1-BN
MHD Synchronous Motors
The Bosch Rexroth Indramat MHD112B-035-PG1-BN motor from the MHD Synchronous Motors series is a high-performance servo motor designed for precision motion control in machine tools, handling systems, automation, and packaging applications. It features a continuous torque at standstill of 28.0 Nm and an integrated holding brake torque of 22.0 Nm, ensuring secure load holding when power is removed. Equipped with a Digital servo feedback w/ integrated encoder, this motor delivers accurate position and speed control for demanding industrial environments.
Constructed with a motor size 112 and a flange size of 192 mm, the MHD112B-035-PG1-BN provides robust mechanical integration and stability. The centering diameter of 130 mm and shaft length code B facilitate straightforward mounting. Its plain shaft design includes a sealing ring to maintain ingress protection, while the absolute position detection (over 4096 revolutions) ensures reliable multiturn feedback. The motor winding code 035 optimizes current density and thermal performance, and the liquid cooling housing enables efficient heat dissipation under continuous heavy loads.
This motor is designed for broad compatibility and durability: the sealed shaft and robust liquid cooling maintain performance in harsh environments, and the output connector to side B streamlines installation flexibility. The power connection type: Output Connector supports secure electrical interfaces, and the permanent magnet synchronous topology reduces maintenance with its brushless construction and grease-lubricated bearings. No external brake control is required thanks to the built-in holding brake, enhancing system efficiency. Certified to Bosch safety guidelines, the MHD112B-035-PG1-BN delivers reliable, efficient operation and superior accuracy for industrial automation systems.

Frequently Asked Questions
What role does the integrated holding brake play during power loss?
It locks the motor shaft automatically when power is removed, preventing mechanical drift or load backdrive. This is critical for vertical or load-bearing applications like lifts or presses.
What maintenance considerations apply to the grease-lubricated bearings?
The sealed bearings require no periodic relubrication, minimizing downtime. Routine visual checks for leakage or noise are sufficient to ensure continued smooth operation.
How does the motor’s synchronous design affect dynamic response?
Permanent magnet synchronization delivers immediate torque response to command inputs. It enables precise acceleration control ideal for pick-and-place and servo indexing systems.
Can the integrated brake operate without a separate controller?
Yes, the brake is electrically engaged and released directly through motor power lines. This simplifies system wiring and reduces control cabinet complexity.
How does the absolute encoder with multiturn detection enhance system safety?
It retains position data even after power-off, eliminating the need for homing routines at startup. This feature prevents unintentional movement and shortens machine recovery times.
