The higher inductance attenuates PWM ripple and limits current-loop crossover, so tuning favors slightly lower bandwidth with adequate phase margin. Its torque constant linearly maps commanded current to torque.

The standardized key geometry simplifies interference-fit hubs and limits micro-slip for reducing torsional play compared with plain friction joints. Its key shear and hub stress under peak bidirectional torque needs to be varified and its select backlash-controlled coupling is to preserve servo stiffness.

The selection ratios that place operating points near the motor’s efficient torque–speed region while keeping reflected inertia within 3–10× of rotor inertia is important. It balances servo bandwidth, limits current spikes and improves contour accuracy on packaging, printing or handling axes.

Its broad flange affords lower interface thermal resistance and higher bending rigidity that improves heat shedding and eigenfrequency. Its flatness, bolt preload and contact area are critical, while poor fitment elevates case temperature and compromises dynamic accuracy.

The separate motor power from feedback cables maintains shield terminations at the drive end and avoids parallel runs with high-dv/dt lines. Use ferrites and proper bonding to reduce common-mode emissions and protect resolver signals from induced noise.
