Design optimisation of permanent magnet assisted synchronous reluctance machines for electric vehicle applications

Comparison of in-wheel permanent magnet motors for electric traction

“…In recent bibliography both approximate and systematized optimization techniques have been proposed for electric traction applications [15][16][17][18][19][20][21][22]. The Taguchi's method along with extended sensitivity analysis techniques have been reported to yield satisfactory results even in demanding aerospace applications [21], in spite their simple nature.…”

Design Optimisation and Performance Evaluation of a Rare-Earth-Free Permanent Magnet Assisted Synchronous Reluctance Machine for Electric Vehicle Traction

“…It is important to note that insulation ratio is a critical parameter in the design of PMA SynRM, since it has a direct impact on the d and q axis inductance difference (L d -L q ) and the PM amount which significantly influence the reluctance torque production. The optimisation was conducted through the use of a powerful FE-based optimisation tool, described in detail in [11]. One machine, denoted as 'NEDC design', was optimised against NEDC cycle, whereas the other, denoted as 'Artemis design', was optimised against Artemis Urban.…”

Optimization of a traction PMASR motor according to a given driving cycle

“…In these works, generally, the design and optimization procedure is based upon rated motor specifications and it does not consider the actual working cycle of the electric car. As emphasized in some recent studies [9]- [11], an optimization performed only on the rated conditions might not yield to an optimal results in the whole driving cycle and a global optimization proves to be an effective solution. In fact, as shown [12]- [14], the motor during a city profile mainly works in low torque operation, far from the rated condition.…”
