1. A Counterintuitive Phenomenon: Why Is Slower More Dangerous?For many engineers, the intuition is that the faster a motor runs, the hotter it gets. But in the world of frameless torque motors, this logic is exactly reversed.A frameless torque motor has no housing, no bearings, and no output shaft.

In industrial automation, robot joint control, and new energy vehicle motor systems, magnetic encoders are playing an increasingly critical role. Through non-contact magnetic field sensing, they convert rotary or linear motion into precise electrical signals, providing the system with position, spee

In applications such as new energy vehicle electric drive systems, industrial servo systems, and aerospace, where precise rotor position sensing is required, the resolver is an indispensable key component. Its job is simple: to tell the controller in real time "where the rotor is now." But there is

Axial flux motors are becoming a popular option for electric drive systems. For the same power output, their volume and weight can be reduced by about 50%, their power density can reach four times that of conventional radial flux motors, and their efficiency can exceed 96%. But if you open product m

Why Eccentricity Is the “Hidden Killer” of Magnetic Encoder AccuracyIn industrial servo systems, robot joints, and precision motion control, magnetic encoders have become a mainstream angle-feedback solution because of their compact structure and strong contamination resistance. However, one easily

I. Why Must High-Speed Motors Undergo Stress Verification?For a high-speed motor with a rotational speed of 30,000 r/min, the centrifugal acceleration at the outer diameter of the rotor can reach tens of thousands of times the gravitational acceleration. Under such extreme operating conditions, the

In scenarios such as robot joints, collaborative robotic arms, and direct-drive rotary tables, frameless torque motors are becoming increasingly common. They have no housing and no bearings; in essence, they are a "bare rotor + stator" power core embedded directly into the mechanical structure, achi

A resolver is one of the most commonly used high-precision angular position sensors in motor control systems, playing a key role especially in drive motors for new energy vehicles, industrial servo systems, and aerospace. Its operating principle is based on electromagnetic induction—the stator windi

Axial flux motors are becoming the “new power darling” in fields such as new energy vehicles, humanoid robots, and low-altitude aircraft—at the same power, they are 50% lighter and 50% smaller in axial dimension. But manufacturing this flat disc-type motor is far from as simple as “flattening a cyli

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
