Frequently Asked Questions
What performance can be expected during dwell-heavy or low-speed indexing processes?
It provides 28.0 Nm continuous torque at standstill, ensuring constant force without rotation. This benefits precision load-holding in motion-control applications.
How does the MHD112B-048-NP1-AN ensure safe shaft locking in gravity-loaded applications?
It integrates a 22.0 Nm holding brake to maintain position during system idle. This supports secure load retention in vertically oriented axes.
Is the mechanical connection robust enough for torque-sensitive drive assemblies?
A keyed shaft ensures reliable axial engagement and resists slippage. It maintains torque stability in applications with frequent load fluctuations.
How is heat dissipation handled during prolonged high-load cycles?
The motor uses liquid cooling to actively manage internal temperature rise. This extends duty life and maintains torque output in closed environments.
Can this unit mount precisely into standardized industrial servo frames?
With a 192 mm flange and 130 mm centering diameter, it aligns cleanly with common servo mounts. This facilitates quick, repeatable mechanical installation.
