High dynamic component bench (e-machine 48V)

This high dynamic bench allows the characterisation of components such as the realisation of a complete cartography of a starter-alternator (48V) of the real torque realised in order to recalibrate the cartography values.

First developed for the aeronautics sector, it is more particularly dedicated to high speed 48V applications, especially in the automotive sector.
