PhD - Abdalla Hussein Rashad Mohamed - Multiphysics Design of Integrated Modular Motor Drives

High power density and efficiency are fundamental requirements in many applications such as electric vehicles (EVs), hybrid electric vehicles (HEVs), propulsion and aerospace applications.

In the context of increasing the power density and efficiency of electric motor drives, integrated modular motor drives (IMMDs) emerge as a solution to obtain both benefits. IMMDs incorporate physical integration and modularization of the electric machine and the power converter. The physical integration brings the electric machine and the power converter into close proximity so that they can share the same cooling circuit and enclosure. The cables connecting the power converter and the electric machine can be completely eliminated or greatly reduced in length leading to elimination or reduced size electromagnetic interference (EMI) filters. The result of the elimination of such components is a highly compact, efficient and power dense electric drive.

In this PhD research, novel highly compact integration solutions for axial flux and radial flux machines are extensively studied through multiphysics simulations and experimental measurements. This thesis is also presenting a novel reconfigurable modular fault-tolerant converter topology for switched reluctance machines. Another contribution of the thesis is the design of an integrated DC-link structure for axial flux machines
