MDD090C-N-030-N2L-130PL1

The “MDD090C” indicates the 90-frame class and C-length, while “N2L” designates the feedback/interface version; thus this variant can interchange with other MDD series motors (same frame/length) given matching drive interface. This modular naming aids in swapping motors in multi-axis systems while maintaining consistent controller compatibility.

The integrator should size the inverter to deliver at least the peak current margin above the nominal current required for 10.4 Nm, factoring in safety and regenerative headroom. They also need to verify that the drive’s voltage and current capability allow full torque delivery across the intended speed range.

The centering diameter acts as a precision reference interface to the mounting flange, reducing misalignment-induced errors. It ensures repeatable positioning and minimizes bending or eccentric loads on bearings.

Exceeding the continuous torque causes excessive winding currents, which raise internal temperatures and degrade insulation over time. The motor's built-in temperature sensors may trigger a drive fault or derate to prevent damage.

A keyway provides positive torque transfer with minimal backlash, but any misalignment or key clearance can create stress concentrations. Care must be taken in hub and key fit tolerances to avoid fatigue or fretting wear under cyclic loads.
