The main contribution of this thesis is the design of two novel integrated modular motor drive topologies: a yokeless and segmented armature (YASA) axial flux permanent magnet synchronous machine and a switched reluctance machine (SRM). These WBG devices are existing in small package size and they dissipate lower power compared to Silicon (Si) devices. The commercially available WBG devices are Gallium Nitride (GaN) and Silicon Carbide (SiC). Using wide bandgap (WBG) power devices in the converter implementation facilitates the design of a small size and low losses power converter module. If a fault occurs in one module, the drive can continue working with the remaining healthy ones. One more advantage of the drive modularity is the fault-tolerance.

This means that the converter is split into several small low rating units with smaller space and cooling requirements. The modularity divides the machine into a number of modules with a driving converter for each module. The design of a modular, small size and low losses power converter facilitates the design of integrated motor drives. A second challenge is the thermal management of this power converter as it resides close to the electric machine windings with its relatively high heat generation. A first challenge is to mount the power converter in a small space inside the machine in a mechanically stable way as it is exposed to the motor vibration. Many challenges have to be met in the design of integrated motor drives. Furthermore, the elimination of the cables reduces the electromagnetic interference (EMI) of the drive which means that the EMI filter can be eliminated or reduced in size, and once again this improves the power density and the efficiency of the drive. The result of this physical integration is a great reduction of the volume, the weight and the power losses of the electric motor drive, which improves its power density and efficiency. The cables connecting the power converter and the electric machine can be completely eliminated or greatly reduced in length. 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. IMMDs incorporate physical integration and modularization of the electric machine and the power converter.

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. My models were printed by 'idbox' using with 0.4 nozzle, 1.75 PLA.High power density and efficiency are fundamental requirements in many applications such as electric vehicles (EVs), hybrid electric vehicles (HEVs), and propulsion and aerospace applications. Raft, Support, Layer Height, Infill: Depending on your experience. Note: When at actual print, each parameter may be adjusted by your experience. (Estimated as case of PLA, 0.4mm Nozzle, 0.2mm Layer Height, 40% infill and No raft and support) “ws” of last 2 digits of file name means “With Support” special designed.

This is “Axial” type “Cutaway” model for the “Running” model. There are “Radial” or “Axial” type of turbine. For “Mid” and “Large” class jet engine starting, the air turbine starter is used to reduce weight than electric starter (motor).Īir starter is driven by pressurized air supplying by APU or ground equipment.
