Besides the latest advances regarding the integration of electric drives in automobiles, either as hybrid or full electric cars, the benefits of electric propulsion solutions are also highly interesting for commercial vehicles. A small size, a high protection class, low fuel consumption and a safe operation are basic requirements, which have to be met in order to design successful solutions. A complete drive system, consisting of a highly efficient permanent magnet synchronous machine with integrated inverter and an effective cooling system, safety- and energy storage devices, was developed in order to fulfill these demands. It is a very compact propulsion system, which could be easily integrated into different existing vehicle concepts. It is already implemented in vehicles and operated in continuous field tests in the full speed and power range. The system proved its effectiveness even in extreme temperature conditions.
