Recently, the Ministry of Technology held a standard training meeting on the new standard GB/T 755-2025 "Rotating Motor Quota and Performance". In accordance with the requirements of the new standards, the promotion and implementation of the new motor standard activities have been firmly promoted. All technical personnel of the company participated in the meeting, and a total of more than 80 people participated in the training.

GB/T 755 "Rotating Motor Quota and Performance" as the most basic and important standard for all rotating motors, it plays a key and important role in standardizing industry technical requirements and unifying testing methods. The GB/T 755-2025 version was released on August 01, 2025, and will be implemented on February 01, 2026.

The standard has been revised many times, and the current version GB/T 755-2019 and GB/T 755-2025 will be implemented soon.
