2026 is set to witness an intensive wave of standard updates in China's motor industry, as four key recommended national standards are scheduled for successive implementation. This move comes amid the country's accelerated push for industrial green transformation and high-quality development, where motors—as core power equipment accounting for over 70% of industrial electricity consumption—play a pivotal role.
Covering both basic general specifications and specialized motor categories, the new standards are poised to refine China’s motor standard system, addressing long-standing industry pain points such as outdated technical norms, inconsistent product specifications, and insufficient coverage of emerging motor technologies. By aligning with advanced international standards and adapting to domestic industrial needs, these updates will provide strong institutional support for the industry’s transition towards high efficiency, energy conservation, and intelligence.
Specifically, the updated standards cover multiple key motor segments with targeted improvements. GB/T 755-2025, which replaces the 2019 version and takes effect on February 1, focuses on rotating electrical machines. It introduces new terms for variable frequency motors—responding to the growing adoption of frequency conversion technology in industrial applications—adds design requirements for high-altitude operations to ensure motor reliability in harsh environments, and supplements test items for permanent magnet motors and synchronous reluctance motors, laying a more solid foundation for the quality control of high-efficiency permanent magnet products.
Scheduled for implementation on May 1, GB/T 6656-2025 replaces the 2008 edition to comprehensively regulate ferrite permanent magnet
Dc Motors, specifying their type, parameters, technical requirements, and test methods. This will help standardize the production of such motors, which are widely used in automotive, household appliances, and light industrial sectors. Meanwhile, two concurrent standards—GB/T 30143-2025 and GB/T 30145-2025—target specialized motors for lifting and metallurgical applications, clearly defining technical specifications and test requirements for wound-rotor and variable frequency speed regulation asynchronous motors with frame sizes 450-500, and filling the specification gap for high-power special motors in heavy industrial scenarios.
