Frequently Asked Questions
What are control implications of the 273.0×10⁻⁴ kg·m² rotor inertia when pairing MKD112C-058-KG0-BN with an IndraDrive?
The inertia achieves bandwidth and dictates the load-to-rotor ratio for stable tuning. Its jerk-limited profiles and appropriate velocity feed-forward to prevent excitation of structural modes during rapid indexing.
Why is a plain shaft with sealing ring and an IP65 enclosure appropriate for packaging/printing lines with airborne particulates or washdown splash?
The sealed shaft path and IP65 closed design resist dust ingress and incidental water jets for protecting bearings and feedback integrity. It reduces unplanned stops from contamination in converting, labeling and cartoning stations.
How do the 133–233 Hz rated frequency band and 4000-rpm characteristic speed shape drive setup on MKD112C-058-KG0-BN (winding code 058)?
They inform voltage utilization and field-weakening thresholds to configure current/voltage limits so half-torque is achievable at characteristic speed without saturation.
How do 38 Nm standstill torque, 148 Nm theoretical peak, and 239 A peak current translate into torque-per-amp for MKD112C-058-KG0-BN?
The peak 0.8 Nm/A class torque constant is used to estimate current demands during acceleration. It ensures the drive and cabling handle transient I²t without clipping motion profiles.
What alignment and coupling concerns arise from the Ø130 mm centering diameter and “C” motor length on MKD112C-058-KG0-BN?
The register controls concentricity to specify a low-backlash, torsionally stiff coupling with misalignment tolerance matching shaft fits. Its face-runout and pilot fit to keep residual radial load within bearing limits.
