Description
In connection with climate change, there is a noticeable global trend towards a long-term shift away from fossil fuels. Electric motors and hybrid drive trains therefore make an important contribution to a sustainable and environmentally compatible mobility concept. Electric motors have also become essential for industrial applications, such as mechanical engineering. Engineers are working to further develop and optimize electric motors specifically for automotive drive trains. Test rigs are an important tool for this development work. Scientists of the KIT Institute of Electrical Engineering (ETI) have developed test rigs for the flexible testing of electric and hybrid drive trains. On the three test rigs at 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 customers can have motors examined, as well as individual drive train components of the power electronics and software. Furthermore, the motor test rigs have a maximum power of 300 kilowatts and can test drives at up to 18,000 revolutions per minute. The maximum torque is 540 newton meters. In addition to that, high-precision measurements of winding resistances can be carried out and thermal components can be used for precise temperature determination. The study results can be retrieved in real time, e.g. in the form of efficiency maps. Development engineers can use these results to verify their simulation models and optimize the electric motors and their motor control.
You can get an overview of this technology at KIT stand. More details can be exchanged individually with the responsible scientific employees of KIT after the industry fair.
