The historical method of performing inverter development on a dynamometer is failing to scale with the increases in activity and features. Without introspection, this leads many organizations to buy more and more dynamometers and search out more highly trained engineers to sit at the control desks to follow those historical development plans. This method results in more capital investment and a large challenge building a team in order to get to the status quo of inverter development circa 2012. This talk will outline a different approach being used more and more frequently in the powertrain industry: the use of an e-motor emulator (EME). With exceptional fidelity emulation capabilities, it becomes possible to disconnect the development efforts from the need to have physical motors and dyno load systems. Many organizations are using the unique capabilities of an EME to re-design their development plans to be shorter, require lower cost of test assets, and provide a level of quality that was not feasible with rotating machines present.
