T/ACREI CREIS34005-2022 The rare earth permanent magnetic material used for the drive motor of new energy vehicles
Basic Information
Scope
Main technical content: This standard specifies the magnetic properties, temperature characteristics, allowable deviations in magnetic performance, allowable deviations in dimensions, corrosion resistance, and other technical requirements of rare earth permanent magnets used in drive motors of new energy vehicles (hereinafter referred to as permanent magnets), as well as testing methods, inspection rules, packaging, and marking. This standard applies to neodymium-iron-boron permanent magnets (which may contain rare earth elements such as lanthanum, cerium, and yttrium) and samarium-cobalt permanent magnets used in the manufacture of drive motors for new energy vehicles. This standard can also be applied to materials used in permanent magnet motors of hybrid vehicles.
