Even though the motor achieves 10.4 Nm at standstill, sustained operation at or near stall torque can lead to internal heating; adequate cooling (convection or forced air) is necessary to avoid thermal de-rating. Overheating reduces insulation life and may force the drive to limit current.

The centering diameter defines the mechanical interface standard for couplings or gearboxes, so you must match or adapt to that interface to avoid introducing misalignment or loads. A mismatch may lead to radial or axial stress on the shaft bearings.

The keyway allows secure torque transmission without slipping, but introduces stress concentrations; the coupling and key must be properly sized to avoid fatigue at high RPM. Also, machining tolerances and key lash can affect backlash and precision in high-dynamic systems.

Cable clamps and strain reliefs are essential to prevent connector fatigue or loosening over time, especially since side-A orientation may expose it to more mechanical stress. Also maintain service bend radii to preserve feedback signal integrity over motion cycles.

At 3000 rpm, rotor inertia becomes a critical factor; the drive must be tuned to ensure the inertia ratio (load/inertia) remains in a stable range to avoid oscillations. Excessive mismatch can lead to control instability or diminished responsiveness.
