The MPN R911286826 (MHD112C-058-PP0-AN) is a synchronous servo motor from the MHD series, designed for use in digital drive controllers in applications such as machine tools and automation. It features a stator, rotor, bearings, encoder, and a keyed shaft with shaft seal. This model is equipped with absolute digital feedback via an integrated multiturn encoder (>4096 revolutions). The motor delivers a continuous standstill torque of 38.0 Nm (value varies with cooling), operates without a holding brake, and supports liquid cooling. The housing conforms to IP65, has a centering diameter of 130 mm, a flange size of 192 mm, and a motor length coded as C. The power output connector is oriented to side A, and the winding code is 058. The motor can operate up to 4500 RPM, at temperatures from 0 to 40°C, and elevations up to 1000 m with class F insulation. Total weight is 45 kg.

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.
