Scope

NB/T 10529-2021 is the English-translated version of 矿用水冷调速型磁力偶合器.

NB/T 10529-2021 covers the water-cooled adjustable-speed magnetic coupling used on coal mine drives, a device that passes torque between a permanent magnet rotor and a conductor rotor by electromagnetic induction and lets the output speed be varied.

The standard gives the model designation, the product requirements, the test methods, the inspection rules, and the marking, packaging, transport and storage of these couplings.

Its references point to explosion-proof enclosure rules of the GB 3836 series, rotor balance quality, NdFeB magnet material, castings, aluminum alloys and the mining product safety mark.

Manufacturers and inspection bodies apply it in design, manufacture and testing. It is issued for the first time; issued on 7 January 2021, it has applied since 1 April 2021.
