Why does the F1iS require strict concentricity to operate at 30,000 RPM?

The stator architecture inductively (without contact) surrounds a thermocompensated rotor capable of registering 3,000 Nm. At these critical frequency regimes and over an anchoring radius, the residual reactive mass requires pure coupling (controlled shaft concentricity) to prevent transient inertias from generating oscillatory harmonics in the supporting system, shielding its 1,143 kNm/rad of torsional stiffness.

What aseptic solidity does inductive telemetry (Dual-Frequency) add?

It avoids the physical noise of capacitive rings and the visual noise of a dusty optical bridge. The F1iS projects its readout and power bridge using galvanized parametric induction, shielding the signal from EMI interference (synchronous motors). Processing at 16 raw bits, it outputs its kinematic chain free of contamination drift.
