Why is the 105.0 mm PCD flange pattern of the DF Plus HS model critical in e-mobility test benches at 40,000 RPM?

At this supercritical speed of 40,000 RPM, any eccentric physical modification induces vibrations. The structural design with a strict 105.0 mm PCD flange pattern ensures a 1:1 drop-in replacement. This instantly eliminates the need to create supplementary mechanical interfaces or destroy the rotor end, guaranteeing perfect inertial integrity.

What parametric measure allows it to withstand dynamic destructive testing of electric vehicles without falsifying the signal?

It is based on the physical architecture of its propulsion system: a rotor forged from ultra-low dynamic inertia titanium alloy (TiAl6V4). By combining this mechanical purity with dual-frequency inductive telemetry, the antenna completely isolates all the EMI radiated by heavy electrical inverters, keeping the signal at Class 0.04.
