These 5 Chinese motor standards have been replaced with the 2023 version
It was learned from the Chinese National Standards Information Platform that five standards related to three-phase asynchronous motors have been adjusted to the 2023 version, of which two standards will be implemented on April 1, 2024, and three standards have been implemented in 2023.
The integration and upgrading of standards is a continuous process. Product manufacturers and users should pay close attention to the dynamics of standards and jointly abide by the technical regulations of motor products.
