Winding

When it comes to buzzwords in new energy vehicle technology, what comes to your mind?
800V platform? SiC power devices? Or hub motors? Among the hottest trends, the hairpin motor (flat wire motor) is certainly leading the pack. Ever since Tesla adopted this technology, discussions surrounding hairpin motors have only intensified. We’ve previously published several technical articles on hairpin motor technology—such as flat wire techniques used in NEV drive motors. Feel free to check them out if you’re interested.

Are you wondering why winding methods are critical in axial flux motor design? As an experienced motor designer, I’ve spent years optimizing winding structures to improve performance, reduce loss, and simplify manufacturing. In this blog, I’ll guide you through the most common and advanced winding techniques used in axial flux motors.

Have you ever wondered what drives the heart of drones, robot vacuums, or electric vehicles? These high-tech machines all rely on BLDC motors, and inside these motors, there’s a fascinating difference in stator winding methods—some follow the “concentrated” camp. In contrast, others belong to the “distributed” side. Don’t underestimate these winding styles—they affect everything from motor efficiency and noise to cost and performance. Behind them are countless engineers’ clever design decisions.

When you start designing a motor, the stator winding type is an unavoidable topic.
For beginners in motor design, seeing various complex winding methods, such as concentrated, distributed, single-layer, double-layer, and flat-wire windings, can be confusing.
