How does the design of the standard TeS model differ from the SeS model operating under the same 100 Nm Z50 hybrid size?

The key difference lies in the metallurgical density of the rotor bridge. While the TeS family transducer lightens its stator using titanium dies, reducing rotational inertia to the clinical limit (0.00210 kg/m²), the SeS abandons weight reduction and instead employs a robust, armored design in pure steel. This dense alloy reduces parasitic mass to 0.00350 kg/m², providing the assembly (always mounted on a 101.5 mm PCD standard) with exceptional mechanical rigidity against elastic vibrations or very abrupt starts and stops on heavy test benches at 25,000 RPM.

Does the density of the steel forging in the SeS Z50 model cause operational interference or weight delay when testing motor peaks?

Paradoxically, rigidity provides neutrality. Despite being heavier than its titanium counterpart, the SeS is a priority member of the electromagnetic-free architecture (eS optical family). Because it communicates via light beams instead of physical inductors, the unit ignores thermal friction and shields the 100% of the 0.05% metric class from EMI short circuits emitted by the e-axle motors. It maintains its speed up to 25,000 RPM while gaining the added mechanical resilience of a solid, pure steel shield.
