Why does the F1eS require a minimized rotational inertia of 0.0113 kgm² working at 30,000 RPM?

When a unit is subjected to acceleration and braking ramps within E-Mobility test benches, the instrument's own moment of inertia distorts the final measurement (by accumulating reactive mass). By reducing the inertia to 0.0113 kgm² and maintaining its geometric concentricity, the F1eS does not compromise the nominal torque of 3,000 Nm and prevents inducing wear due to resonance (flutter), guaranteeing its massive rigidity of 1,143 kNm/rad.

What aseptic robustness does the optical core add compared to classic inductive systems?

The optical architecture acts as an electromagnetic immunity (EMI) bunker. In banks with power inverters and drives with extremely high dV/dt switching rates, magnetic fields corrupt the inductive chains. The optical system reads variations from the slotted disk, delivering curves with rectilinear bandwidths of 10 kHz, guaranteeing Class 0.05 aseptic metrics through a truly tamper-proof RS422 chain.
