Better electric cars through a highly compact and efficient electric drive system

(07-01-2022) In his PhD, Abdalla Mohamed investigated how an electric drive can be made even more compact and efficient.

High power density (measure of the effectiveness of the energy source) and efficiency are fundamental requirements in many applications, such as electric vehicles, hybrid vehicles and space applications.

"In the context of increasing the power density and efficiency of electric motor drives, integrated modular motor drives (IMMDs) are emerging as a solution that combines both benefits," Abdalla explains.

These integrated modular motor drives include physical integration and modularization of the electrical machine and the power converter. The physical integration brings the electrical machine and the power converter close together, allowing them to share the same cooling circuit and housing. The cables connecting the power converter and the electrical machine can be completely eliminated or significantly reduced, leading to elimination or reduced filters for electromagnetic interference (EMI).

The result of the elimination of such components is a very compact, efficient electric drive with high power density.

"In my doctoral research, I was looking for new, very compact integration solutions so that electric drives can become even better in the future," Abdalla concludes.
