How are magnets fixed inside the rotor core of a permanent magnet motor? This is one of the most important questions in modern drive motor design. Since most drive motors today are permanent magnet synchronous motors (PMSM), magnets fixing methods directly affect motor performance, safety, and reliability. A small number of drive motors still use asynchronous motors, but they do not involve magnets at all.
Have you ever thought all linear motors look the same? Think again! Choosing between Ironcore and Ironless Linear Motors is like choosing between a powerlifter and a ballet dancer—they both excel, but in completely different ways. Pick the right one and your production line runs smoothly. Pick the wrong one and you could face inefficiency or even downtime.
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.
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?
In recent years, many automakers have talked about applying axial flux motors in new energy vehicles. But due to manufacturing difficulties and high costs, most companies were still waiting and watching. However, at this year’s Shanghai Auto Show, several companies showcased their axial motor products. Let’s take a look together. Personally, I see great potential for axial flux motors as range extenders.
