his paper presents a survey about
implementing hairpin winding with an oil spray cooling system
on the new generation of electrical vehicle (EV) motors as an
option to produce high power density, high efficiency, costeffectiveness,
lightweight, reliable EV motors. It provides the
advantages and drawbacks of this rectangular winding
compared to random winding and considers the hairpin
winding production aspects. According to the high AC losses of
this configuration, the paper considers two conventional
approaches for calculating these losses with their advantages
and drawback. Then it proposes the novel hybrid FEA method
for calculating the AC copper losses to overcome the
weaknesses of analytical and numerical methods. Finally, it
provides a holistic view related to the oil spray cooling of the
electrical machine and points
