“…The results obtained have a good agreement with the FE ones. Fig.4 shows the comparison between the analytically and the FE calculated winding losses in a coil under no-load (J = 0; Br = 1.02T) and also on peak load (J = 16.05 A/mm 2 ; Br = 1.02T) conditions, respectively. The obtained results are shown in Fig.4 to be in a good agreement.…”

“…This is due to the role of eddy current and their reaction effect that change the current distribution within the conductor resulting in a decrease of eddy current losses [3]. It is worth noting that this reaction effect depends on the size and structure of the conductor [2].…”

“…Here, it is worth highlighting that although the application of Litz wire/ multi-stranded bundle conductor significantly limits the effects of eddy current losses due to skin effect [1,2], the winding eddy losses due to the proximity effect still persists. In addition direct current (DC) winding losses also increase due to the poor fill factor of the Litz wire/ multi-stranded bundle conductors.…”

AbstractThis paper investigates the influence of eddy current losses in multi-stranded bundle conductors employed in outrunner permanent magnet machines, by adopting an analytical model. The analytical model is based on a sub-domain field model that solves the two-dimensional magnetostatic problem using the separation of variables technique for each of the non-magnetically permeable machine sub-domains: PM, airgap and slots. The validity and accuracy of the proposed model is verified using finite element analysis and then used to investigate the eddy current losses. The machine considered for the analysis has 36 slots and 42-poles previously designed for aircraft taxiing. The influence of the number of turns and the conductor cross-sectional area are investigated. It is shown that efficiency can be improved considerably by the choice of multi-stranded bundle conductors.

“…In [8,9], instead of having separated H-bridge for each phase, three-level inverter which control a three phase winding unit, has been proposed. It has been demonstrated that having three phase unit controlled by an inverter unit simplifies the control strategy and provide balance operation under a fault.…”

“…Although monitoring insulation and so performing safe operation at an event of fault can be possible, the monitoring shield of the winding introduces the eddy current losses whilst the armature windings increases DC losses due to reduced fill factor. Adopting the methods proposed in [8,13,14], the SC can be limited and thus, FT can be improved but, the efficiency of the machine needs to be compromised. A trade-off is therefore required to find a fine balance between FT and efficiency.…”

In Permanent Magnet (PM) machines, a turn-turn Short-Circuit (SC) fault is the most critical fault to eradicate. The fault introduces high SC current in the shorted turn which may consequently lead to secondary faults unless the fault is appropriately controlled. This paper proposes feasible conductors' placement in a slot of PM machine to minimize such turn-turn fault current. In order to minimize the fault current, the conductor arrangement in a slot is optimized using multi-objective Genetic Algorithm (GA) incorporating with both analytical and Finite Element (FE) numerical tool. The possible combinations of conductors' placement are set as variables and optimized for a given machine which is designed for safety critical applications. It is shown that the fault current associated to a single turn fault can be significant for the random winding placement even though the remedial strategies are put in place. It is also shown that the fault current can be limited significantly by rearranging the winding placement in a way to share slotleakage fluxes. This is confirmed via experiment on E-core. Influences of the winding arrangement on both frequency dependent resistances and windings capacitances are experimented. It is demonstrated that adopting the winding arrangement that shares the slot-leakage flux effectively benefits to minimize the AC losses in addition to improved fault tolerance. But it increases the turn-turn capacitances whose effect however can be neglected as the resonance frequency occurs beyond the operational frequency range of the machines of interest.
