4 Stacking Methods for New Energy Permanent Magnet Synchronous Motor Cores

4 Stacking Methods for New Energy Motor Cores

How does the stacking method of stator and rotor cores affect the performance of a new energy vehicle motor? As a core lamination designer with years of experience, I often encounter this question. In fact, the stacking method directly influences the efficiency, reliability, noise level, and cost of EV motors. Choosing the right method is critical—especially for high-performance permanent magnet synchronous motors (PMSM) used in electric vehicles.

Hairpin Motor Stator Winding: 6 Essential Processes

Hairpin Motor Stator 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.

Axial Flux Motor Winding Methods: What You Need to Know

Concentrated Winding vs Distributed Winding

Are you wondering why winding methods are critical in axial flux motor design?
