High-Speed Motor Rotor Dynamic Balancing: Why Are Requirements More Stringent at Higher Speeds?

A motor with a speed of 30,000 revolutions per minute can, with even just a few milligrams of rotor mass eccentricity, generate centrifugal force sufficient to destroy its bearings within a few hours. This is no exaggeration—when speed increases by an order of magnitude, the vibration energy excited

Radially Magnetized Vs. Axially Magnetized Magnetic Rings: What’s The Difference?

In many motors, sensors, and magnetic transmission devices, we often encounter a key component—the magnetic ring (or magnet ring). It may look like a simple circular ring, but different magnetization directions can lead to completely different performance and application scenarios.The two most commo
