In micro-motors, stepper motors, servo systems, magnetic encoders, and various high-precision sensors, the multi-pole magnetic ring is a core component. It acts like a “magnetic gear” with alternating N and S poles, providing precise rotational position and speed information for the equipment. Howev

Magnetic levitation motors, with their advantages of contactless operation, zero friction, and high efficiency, are gradually replacing traditional motors as the mainstream choice for high-speed rotating machinery. However, during high-speed operation, even the slightest mass eccentricity in the mag

In high-precision motion control applications such as robot joints, servo motors, and gimbals, magnetic encoders are increasingly becoming the core position-feedback devices, thanks to their non-contact operation, immunity to contaminants, and compact size. However, many engineers encounter a frustr

I. What Is a Magnetic Levitation Motor Rotor?When people hear “magnetic levitation,” many immediately think of the maglev train that “flies” along the track at Shanghai Pudong Airport. But few know that the same magnetic levitation technology has long since moved from the rails into bearings.A magne

In the surging wave of humanoid robotics, frameless torque motors have become the core choice for joint actuation, thanks to their compact size, high power density, and high torque at low speeds. Unlike conventional motors, frameless torque motors dispense with the housing, bearings, and base, retai

I. What Is a Resolver Sensor?In the drive motor of an electric vehicle, there is an unassuming yet critical component—the rotating transformer, commonly known as a “resolver.” It is often described as the “eyes” and “ears” of the motor control system.A resolver is an analog angular sensor that opera

I. The "Survival Test" under High-Speed RotationMagnetic levitation motors, with their advantages of contactless operation, high efficiency, and extremely high rotational speeds, are increasingly being adopted in high-end equipment such as industrial blowers, compressors, and energy storage flywheel

1. Signal Jitter: The Core Pain Point in Robot Joint ControlIn applications that demand stringent position control – such as robot joints, pan-tilt units, and high-precision servo systems – magnetic encoders are rapidly replacing traditional optical encoders thanks to their non-contact operation,

Magnetic bearing motors, with their advantages of contactless operation, no wear, and high efficiency, are rapidly replacing traditional motors in fields such as high-speed compressors, blowers, and flywheel energy storage. However, when rotation speeds reach tens of thousands or even over one hundr

Inside the joints of industrial robots, on the shafts of servo motors, and at every motion node of humanoid robots, there hides an inconspicuous yet vital component – the magnetic encoder. It acts as the robot’s “joint nerve,” capturing speed, position, and angle in real time,
