Electric powertrain and transmission dynamic bench

This type of dynamic bench with double machine allows to characterize complete electric powertrain (eGMP) but also gearboxes or for combustion engine (and hybrid and micro-hybrid) the mechanical gearbox.Depending on the way this bench is set up, the transmission devices or devices associated to the modification of vehicle kinematics can be characterized.
