Up to five eMachines -dynos- arrangeable in different configurations (e.g. set onto T-slotted bench on vibration isolation air bellows); either of them driving and braking (either acting as motor or generator) and working jointly or separately in a fully flexible way.
Loading torques in both directions while spinning in both directions as well (4-quadrant operation) are intended to conduct both durability tests (endurance, gear tooth scoring…) and functional tests (efficiency, clutch mapping, gear whining, NVH-mapping…) on many powertrain components such as:
• Differentials (LSD, LUD, FRRD)
• Transfer boxes (PTU, FDU, RDU)
• Active powertrain components (ETM, EMCD)
• eDrives / eAxles.
