The electric traction motor is a central component in many modern drive concepts. In hybrid vehicles and also in pure electric vehicles, controlling and regulating these motors is a major factor in achieving development goals regarding efficiency, emission reduction and vehicle dynamics. As an additional component in the drivetrain with significantly increased dynamics in comparison to internal combustion engines, the electric motor is posing new challenges for development engineers and development tools. This also affects hardware-in-the-loop (HiL) simulation, which is now an established step in the development of automotive electronic control units. dSPACE describes some of these challenges and presents possible solutions showing what HiL test benches for electric motors could look like.
