With rising demands for lightweight, high-efficiency, and heat-resistant electric motors—especially in EVs and industrial automation—adhesives have become critical components in manufacturing, not just auxiliary materials. From magnet bonding and coil potting to thermal interface management and structural sealing, adhesives directly impact motor reliability, thermal stability, and production efficiency.
Which eVTOL motor design is truly the better path forward? The debate of Archer motor VS Joby motor has drawn great attention in the electric aviation industry. Archer Aviation and Joby Aviation have taken completely different technical routes for their eVTOL aircraft. One focuses on a high‑speed geared architecture similar to automotive drive systems, while the other pursues an ultra‑high torque direct drive solution.
Porsche has long been the gold standard in sports cars—combining stunning design with outstanding performance. But how does their first electric sports car, the Taycan, stack up when it comes to motor technology? In this article, we’ll break down the design and features of the Taycan's electric drive system, and take a brief look at how it compares with one of its fastest rivals—the Xiaomi SU7 Ultra.
What makes a PMSM rotor not just functional—but powerful, efficient, and safe at high speeds? As a manufacturer with years of experience in permanent magnet motor rotors, I’ve worked with countless engineers to turn their designs into real-world solutions. Over time, I’ve realized that many designers and enthusiasts are curious about how PMSM rotors are actually built—from structure to material to performance under stress.
As a drive motor manufacturer with years of experience in motor cooling system design, I often get asked: how do electric vehicles manage the enormous heat generated by high-performance motors? Whether it’s a pure electric car or a hybrid, e-drive systems deliver impressive acceleration and power—but they also bring significant cooling challenges. So how are these heat issues solved?
If you're sourcing motors for demanding environments — where heat, humidity, and vibration are constant challenges — then the quality of your stator insulation isn’t just important, it’s critical. That’s why more and more customers are turning to Vacuum Pressure Impregnation (VPI). Unlike traditional dipping methods, VPI delivers deep, uniform insulation that dramatically improves reliability, extends motor life, and reduces maintenance costs. But what exactly happens during the VPI process — and why is it considered the gold standard for stator windings?
Motor overheating and low efficiency—what’s the real problem? If you work in motor design or deal with motors regularly, you may have noticed that sometimes, even when the winding and control system are perfectly fine, the motor still gets hot and its efficiency doesn’t improve. The problem often lies in one critical area—excessive core loss in the stator.
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.
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.
