Frequently Asked Questions

Why is natural convection on MKD112D-027-GP3-BN advantageous for duty cycles with intermittent peaks?

The elimination of auxiliary fans removes airflow-dependent failure modes and reduces contamination paths. Its thermal constants and the motor’s surface design allows acceptable winding temperatures while sustaining cycles defined by the controller’s current limits.

What coupling benefits arise from the 35 mm keyed shaft and shaft seal on MKD112D-027-GP3-BN?

The keyway provides shear-resistant torque transmission for minimizing micro-slip under bidirectional indexing. Its sealing element mitigates ingress to preserve bearing lubrication and maintaining axial runout tolerances over extended maintenance intervals.

How do the 192 mm flange and 130 mm centering diameter help retrofit work on machine tools and packaging axes?

Its standardized geometry aligns with common IEC-style mountings that shortens adapter plate design. Its pilot bore constrains eccentricity for reducing alignment error that would otherwise inflate torque ripple during precision contouring.

On MKD112D-027-GP3-BN, how is a 48.0 Nm standstill torque reconciled with thermal limits during holding with a 70 Nm brake engaged?

The brake sustains static loads mechanically to allow the controller to reduce holding current and copper losses. It preserves winding thermal headroom for subsequent accelerations without lengthening dwell times.

How does the output power/feedback connectorization on MKD112D-027-GP3-BN reduce commissioning defects?

Its discrete power and feedback connectors maintain shield terminations and pair-twist integrity for lowering induced noise into resolver lines. Its standardized pinouts streamline harness validation and diminish polarity/wiring reversals at installation.
