How does the 70 Nm holding brake on the MKD112C-058-GP3-BN maintain axial stability during power loss or an E-stop?

Its electrically released brake applies clamping torque when de-energized to prevent back-driving on vertical or suspended loads. Its 70 Nm rating provides substantial static holding margin for fine-pitch ball-screws and belt transmissions to improve stop-state determinism and restart repeatability.

How do the 192 mm flange and 130 mm centering diameter of the MKD112C-058-GP3-BN influence mounting accuracy and rotor–load concentricity?

The large pilot and bolt circle minimize eccentricity and simplify coaxial alignment for reducing radial load on bearings. Its correctly toleranced locating fit improves coupling balance at speed to lower vibration and enhances interpolation quality on precision axes.

Why is the MKD112C motor’s 38.0 Nm continuous torque at standstill relevant for indexers and dwell-heavy profiles?

The continuous static torque allows sustained holding without thermal runaway during long dwells or clamp cycles. It supports aggressive S-curve profiles where average speed is low but high static torque is repeatedly demanded.

How does a sealed output shaft contribute to reliability on the MKD112C-058-GP3-BN in washdown-adjacent or dusty cells?

The shaft seal mitigates ingress of contaminants and lubricant egress to preserve bearing life and insulation integrity. It reduces maintenance intervals in environments with atomized coolants, paper dust or packaging particulates.

What tuning and bearing-load considerations arise from 3000 rpm rated and 6000 rpm maximum speed on the MKD112C-058-GP3-BN?

The servo gains follows mechanical resonance and back-EMF near the upper speed region to avoid saturation. Its bearing preload and coupling balance become increasingly critical above rated speed to control heat and axial growth.
