Product description

In connection with climate change, a worldwide trend to do without fossil fuels in the long term can be noticed. Consequently, electric motors and hybrid drive trains will be important in the future sustainable and environmentally compatible mobility concept. Electric motors are inseparably linked with industrial application, e.g. in mechanical engineering. Engineers are now further developing and optimizing electric motors in particular for driving automobiles. Important tools in this development work are test rigs.

Scientists of the KIT Institute of Electrical Engineering (ETI) have developed test rigs for the flexible testing of electric and hybrid drive trains. In three test rigs of KIT, developers can study electric motors used to drive vehicles, from small cars to racing cars to small trucks.

The power electronics and software required to control the test rigs and motors have been developed by KIT engineers. They are designed in a modular manner. Hence, operation of the test rigs is extremely flexible. Industry partners and clients cannot only ask the KIT to study complete motors, but also single components, including power electronics and software. The KIT test rigs are characterized by a high maximum power of 250 kW and reach up to 30,000 revolutions per minute.

The study results can be retrieved in real time, e.g. in the form of efficiency characteristics. A good energy efficiency of the motor is reflected by a green area in the diagram. Based on the measurement results, development engineers can verify simulation calculations and optimize the electric motors and motor control. The test rigs contribute to future electric motors using the energy more efficiently, improving dynamics, and the vehicle reaching higher speeds and accelerations.

KIT looks for partners interested in using the test rigs for testing and further development of electric motors.
