Scope

Scope: This standard specifies the basic technical requirements, test methods, inspection rules, marking, packaging, and storage for basic permanent magnet couplers. This standard applies to permanent magnet couplers with operating temperature ranges of -55°C to 70°C, which possess the capabilities of isolating system vibrations, cushioning startups, and mitigating load impacts. Main technical content: 3.1 Permanent magnets: The block-shaped permanent magnets used in permanent magnet couplers are made of high-temperature rare earth strong magnetic materials such as neodymium iron boron. 3.2 Permanent magnetic couplers: A device used in coaxial drive systems, placed between the active equipment (drive motor) and the driven equipment (working machine), which achieves non-contact transmission of torque and motion through the interaction of the permanent magnet's magnetic field with its induced magnetic field. Also known as permanent magnetic eddy current motor couplers or permanent magnetic couplers. 3.3 Permanent magnet rotors: A rotating body composed of a coupling hub and a disk assembly, with permanent magnets embedded in the disk assembly. 3.4 Conductor rotors: A rotating body composed of a coupling hub and a disk assembly, with a conductor disk in the disk assembly. 3.5 Air gap: The gap between the permanent magnet rotor and the conductor rotor, with the magnetic field distributed within the air gap forming an integral part of the permanent magnetic coupler's magnetic circuit. 3.6 Slip ratio [s]: The ratio of the difference between the input speed and the output speed to the input speed, expressed as a percentage. 3.7 Rated torque [Tn]: The maximum torque that can be transmitted continuously under rated operating conditions within the adapted temperature range. 3.8 Maximum torque [Tmax]: The maximum torque that can be transmitted during an overload within the permitted overload time within the adapted temperature range. 3.9 Permitted overload time [ta]: The time
