Have you ever wondered how electric vehicles achieve such precise motor control at high speed? The answer lies in the resolver. This position sensor plays a vital role in detecting the exact rotor angle and speed of a motor, then sending this information back to the controller. Without an accurate resolver, even the most advanced motor would fail to deliver smooth performance, efficiency, and safety.
When choosing an electric motor, how do you decide which technology is best for your application? If you’ve heard about Switched Reluctance Motor VS. Synchronous Reluctance Motor but aren’t sure about the differences, you’re not alone. Both motor types share the same fundamental principle—using magnetic reluctance to create torque—but their structures, control methods, and performance characteristics vary greatly.
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.
