Arbitrary d–q current sharing in three-phase winding sets of multi-phase machines
The Journal of Engineering, 2019 This study proposes a technique for arbitrary current sharing between winding sets of any multiple three-phase machine by using a decoupled control in two-dimensional orthogonal vector space decomposition subspaces.

Integrated approach to NVH analysis in electric vehicle drivetrains
The Journal of Engineering, 2019 This paper presents an approach to noise, vibration and harshness (NVH) analysis suitable for electro-mechanical rotating systems, whereby both the electrical and mechanical sources of excitation are included and the response of the system is calculated.

Numerical investigations of convective phenomena of oil impingement on end-windings
The Journal of Engineering, 2019 A novel experimental rig for analysing intensive liquid cooling of highly power-dense electrical machine components has been developed. Coupled fluid flow and heat transfer have been modelled, using computational fluid dynamics (CFD), to inform the ...
