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.

The F1eS series stands as the ultimate mechanical integration platform for e-Mobility testing that demands unconventional bandwidths. Its optimized rotor design ensures strict mounting concentricity on a reactive mass of just 0.0113 kg·m², consolidating a dynamic coupling that absorbs overloads from the 400% without inducing fatal resonances in the test bench. Operating at up to 30,000 continuous RPM, it acts as a passive structural component capable of absorbing thermomechanical shocks of 650 m/s² within a range of -20°C to +85°C.

At the acquisition level, this transducer overcomes inductive limitations by implementing an optical signaling bridge. This architecture provides pure linearity and a stabilized 10 kHz frequency response, achieving absolute EMI immunity against magnetic saturation of traction inverters. Reporting aseptic metrics of Class 0.05% via RS422 (60 kHz) and CAN Bus 2B outputs, it parameters transient harmonics undetectable by other means.
