Frequently Asked Questions

Why does the MDD115D-N-015-N2L-180PA0 use a keyway shaft with a shaft seal, and how does that influence coupling design?

The keyway offers positive mechanical engagement for pulleys/gearboxes under cyclical torque for minimizing micro-slip. Its seal limits ingress of particulates/fluids at the shaft journal for protecting bearings and windings during factory washdown and dusty processes.

How does the 180 mm centering diameter influence mounting stiffness and concentricity on the machine face?

Its larger pilot diameter improves radial location, reducing reliance on bolt shear and helping concentric alignment of couplings. It translates into lower vibration, better bearing life and improved repeatability during rapid reversals.

How does Side-A connector orientation on MDD115D-N-015-N2L-180PA0 affect cable routing and EMC practices?

Its placement simplifies straight-through cable dress when the motor faces the machine’s service side. It is important to maintain segregated power/feedback paths with proper shielding and strain relief to preserve signal integrity.

What cooling/thermal assumptions apply to the 115 frame, and how does that impact duty planning?

The MDD 115 variants are configured for natural convection/surface cooling, it is important to ensure airflow and clearance to achieve catalog thermal constants and ambient limits. Its proper thermal design preserves continuous torque capability and avoids derating on enclosed installations.

What are the practical implications of the motor’s approximate mass and rotor inertia on MDD115D-N-015-N2L-180PA0?

Its 60 kg mass and ~0.000271 kg·m² inertia influence axis tuning and acceleration planning, especially with direct-drive couplings. Its drive sizing should consider load inertia ratio and cycle profile to avoid overshoot.
