Why would a behemoth like the F4eS (60,000 Nm) use shielded optical telemetry if the testbeds are not going to rotate at extremely high RPMs?

The F4eS's optical architecture is not primarily implemented in this model for speed, but to solve a critical problem in the massive calibration process: destructive magnetic disturbance. When evaluating enormous synchronous motors or traction machinery testbeds, the inverters (dV/dt traction inverters) emit colossal magnetic fields (EMI noise). By injecting light telemetry without metallic conductivity across the air gap, the F4eS leverages its enormous physical inertia (1.6378 kgm²) on the 369.0 mm PCD flange, structurally blocking excess energy, and performs electronic evaluation without external galvanic magnetic signal drift, guaranteeing pure Class 0.10 accuracy.

Does it maintain the standard mounting flange and passive mechanical metrics when dispensing with inductors?

Absolutely. The F4eS inherits the Heavy Duty parametric scaffolding with millimeter precision. Like the inductive variable, it is embedded in the 418 mm machined ISO concentric external gigabridge (PCD anchor 369.0 mm). In doing so, it mechanically pulls its calculated total inertia mass of 1.6378 kg·m², establishing 75,300 kNm/rad of solid torsional stiffness against sudden braking in asymmetric simulations of heavy machinery or wind turbine e-axles.
