Hairpin Windings: an opportunity for Next Generation E-Motors in Transportation

The advancements in electrical machines and power electronics technologies seem permitting to achieve the power density and efficiency levels required nowadays by the transportation sector. However, the reliability of components and of their production process is currently a challenge. This is especially true for electrical machines, whose winding processes are still far from obtaining the high levels of automation, programmability and repeatibility required by the transportation market. This article looks into hairpin windings and outlines a number of future actions aiming to address these challenges, thus eventually enabling the complete penetration of hairpin windings in transportation.
