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?
