How to get more power out of an electric machine?
In a Drive-Motor System, the Drive has a significant influence on the losses of the electric machine. This presentation focuses on the inverter hardware topology and software, in particular, on how they allow a higher utilization of the electric machine. A comparison between the same electric motor driven by two different inverter topologies is shown analytically. The results of the analytical computations are confirmed by a cross industry case in which a one to one comparison, over a daily operation, highlights significant efficiency gains. The end result of the improved performance is a downsizing of the drivetrain components.
