Permanent-Magnet Hysteresis Clutch Selection Guide: Constant-Torque Use Cases
Wire tension, bottle-cap torque, surgical instrument torque limiting — a quick-reference walkthrough of common selection pitfalls and torque calculation for hysteresis clutches in constant-torque applications.
How Planar Magnetron Cathode Design Drives Coating Uniformity
Why does the same coating tool produce wildly different uniformity in different operators' hands? The answer usually lies in cathode magnetic-field design and target utilisation details.
Best Practice: Magnetic Reactor Drives for Pharmaceutical Sealing
API pharma, biological fermentation, specialty chemicals — a single micro-leak in a reactor seal is a compliance incident. How magnetic drives became the cGMP-preferred choice.
Cylindrical vs Rotary Magnetron Cathodes: Choosing by Process
Cylindrical doesn't rotate; rotary is always cylindrical. The two cathodes look similar but have very different process boundaries. Comparing on 4 dimensions.
Handheld Pole Gauge for Production-Line QC: A Field Case Study
Motor factories, magnetic-assembly plants, medical magnets — how a handheld pole gauge cut wrong-polarity assembly defects to under one per million.
Constant-Torque Clutch
Permanent-magnet hysteresis clutches and brakes — torque freely set, constant at any speed, no external control or power required, reliable, low maintenance, flexible mounting, customisable enclosure, can be designed for fine torque-variation engagement applications, used for…
Magnetic Coupling Drives Adopted on Continuous Vacuum Coating Lines
Magnetic coupling drives have replaced previously-used magnetic-fluid drive seals on continuous coating lines. End users: CSG Display, Leybold-Heraeus. Integrators: Xiangtan Hongda, Xiangtan Yufeng. All-in-house IP, customisable to spec. Contact: 13823228656
Magnetically-Sealed Motors
In 2007 we first introduced the "magnetically-sealed motor" concept, using magnetic coupling to extend a motor's serviceable environments and simplify on-site use. Now successfully deployed in toxic/hazardous gas, high/low-temperature testing, vacuum, and other sealed equipment —…
