MHD112C-058-PP0-AN
MHD Synchronous Motors
The Bosch Rexroth Indramat MHD112C-058-PP0-AN from the MHD Synchronous Motors series is a high-precision Servo Motor engineered for dynamic automation tasks. It uses a Motor Size 112 frame combined with a Motor Length C housing to optimize power density and installation depth. Precision mounting is achieved via a Centering diameter of 130 mm and a standardized Flange size of 192 mm, ensuring tight radial alignment and ease of integration. Mechanical robustness is provided by a Keyed Shaft design with an integrated Shaft Seal, while electrical connections are delivered through an Output Connector oriented to side A and a Winding Code 058 configuration for predictable electromagnetic performance.
Thermal regulation is handled by an efficient Liquid cooling system that sustains continuous operation under full torque without thermal throttling. Feedback control is driven by a Digital servo feedback w/ integrated encoder that provides high-resolution speed and position data. The motor implements Absolute position detection (>4096 revolutions) to guarantee accurate multi-turn reference tracking even after power cycles. With a Continuous Torque at Standstill of 38.0 Nm and operating Without holding brake, this servo motor balances torque capability and simplified mechanical interface.
In summary, the MHD112C-058-PP0-AN delivers a blend of mechanical precision, advanced feedback, and thermal resilience suited for demanding servo applications in robotics, packaging, and CNC machinery. Its Liquid cooling housing and Absolute position detection ensure stable accuracy and repeatability over extended duty cycles. Designed by Bosch Rexroth Indramat, this motor offers a turnkey solution for engineers seeking reliable performance and streamlined integration.

Frequently Asked Questions
What advantages does the digital servo feedback with integrated multi-turn absolute encoder (>4096 revolutions) on the MHD112C-058-PP0-AN provide for homing and restart sequences?
The multi-turn absolute system retains position across power cycles for eliminating homing moves and fixtures after restarts. Its higher-resolution feedback improves loop gain, reduces following error and eases disturbance rejection in fast axes.
How do the 130 mm centering diameter and 192 mm flange interface affect mounting concentricity, stiffness, and coupling alignment in precision assemblies?
The standardized spigot and flange establish radial datum and bolt-pattern rigidity for reducing eccentricity and axial wobble at the motor–machine interface. Its better concentricity simplifies coupling alignment and maintains encoder-to-load correlation at high speeds.
Why is a keyed, sealed shaft specified on the MHD112C-058-PP0-AN, and which coupling styles best exploit that geometry?
The key transmits torque without relying solely on friction and the seal limits ingress of coolant and contaminants. Its zero-backlash clamp-hub or elastomer jaw couplings maintain alignment while damping torsional ripple.
How does the power connection orientation to side-A on the MHD112C-058-PP0-AN influence cable routing and electromagnetic compatibility inside compact gantry enclosures?
The side-A connectors shorten cable runs and allow separation from feedback harnessing for easing EMC management and bend-radius constraints. Its predictable exit direction simplifies strain relief, drag-chain layouts and maintenance access.
What maintenance and environmental points follow from the sealed construction and liquid-cooled housing common to the MHD series?
Its sealed bearings and housings minimizes lubrication tasks, while coolant quality and flow verification dominate preventive checks. Its proper filtration prevents fouling for ensuring thermal performance and encoder stability across multi-shift operation.
