Frequently Asked Questions

What mechanical fit benefits come from the 130 mm centering diameter and Motor Size 115/Length D geometry?

The 130 mm pilot simplifies concentric mounting, improves shaft alignment and reduces runout-induced vibration. Its 115/D frame standardizes interchange with MDD series flanges and couplings across machine families.

How does the side-B connector orientation help cabinet wiring and EMI management on R911274244 installations?

Its side-B power/feedback orientation allows straight cable egress away from coolant spray or guideways for easing separation of motor and encoder leads. Its routing reduces coupling noise and improves service access.

What role does the shaft seal and plain-shaft interface play in contamination control and coupling selection?

The shaft seal limits ingress of dust and fluids at the front bearing for supporting long service intervals. Its plain, keyed coupling interface offers broad compatibility with backlash-controlled bellows or clamp hubs.

How does standard balancing on the rotor affect vibration and bearing loads over the speed range?

The standard balancing reduces residual unbalance that otherwise excites structure modes for improving surface finish and encoder fidelity. It minimizes bearing reaction forces at duty speed for helping maintain alignment with the 130 mm centering pilot.

How does digital servo feedback (DSF) on MDD115D-N-015-N2L-130GB2 improve loop tuning and position verification?

It provides high-resolution rotor position and speed data for enabling tighter current/velocity loops, more stable gains and quicker settling. It also stores motor parameters for streamlining startup and preventing parameter-mismatch faults during commissioning.
