Frequently Asked Questions

How is shaft protection ensured in demanding industrial environments?

The plain shaft includes an integrated shaft seal to block contaminants. This enhances long-term reliability in dust- or fluid-exposed applications.

Can the MHD112B-058-PP0-RN deliver constant torque when the rotor is stationary?

It provides 28.0 Nm of continuous torque at standstill. This supports load-holding in indexing or zero-speed dwell operations.

What feedback mechanism supports position tracking in automated systems?

The motor uses digital servo feedback with an integrated encoder. This enables accurate and responsive closed-loop motion control.

How does the motor maintain thermal performance under sustained load?

Its liquid-cooled housing regulates heat during high-duty operation. This ensures stable performance without thermal derating.

Will the mounting interface align with standard industrial servo platforms?

It features a 192 mm flange size for standardized mounting compatibility. This simplifies integration into modular machine assemblies.
