Temperature Rating Selection for Magnetic Encoder Disks Under High/Low-Temperature Conditions: Injection-Molded Ferrite Vs. Rubber Magnet—Don’t Just Look at The Word “Ferrite”

After a collaborative robot runs continuously for several hours, its position feedback begins to drift slowly. When the joint is disassembled, the magnetic encoder disk looks intact, and its magnetization shows no obvious abnormality, but when it is retested at room temperature, the angular error do

New Energy Main Drive Motor Resolver Sensor Selection: Five Engineering Judgments That Are Easy To Underestimate

For position sensor selection in main drive motors, the resolver is almost unavoidable. But “choosing a resolver” itself is not difficult. What is difficult is making the few judgments behind the datasheet that truly determine mass-production performance: whether the pole pairs match the motor, how

Load-to-Motor Inertia Ratio for Frameless Torque Motors: From “Stability Shackles” To A “Yardstick for Acceleration Capability”

In traditional servo selection, the inertia ratio is often treated as a red line: exceed the recommended value, and the system may oscillate, overshoot, or become difficult to stabilize. However, when the actuator is replaced by a frameless torque motor and the transmission is replaced by direct dri

Surface-Mounted High-Speed Rotor Magnet Retention: Why “the Adhesive Will Hold It” Is The Most Dangerous Illusion

In a high-speed permanent-magnet motor running at more than 20,000 rpm, every magnet on the rotor periphery experiences a centrifugal force dozens of times its own weight. If the designer assumes that “a better adhesive will hold it,” the result is often that at some point in durability testing the
