This standard applies to permanent magnet synchronous traction machines for all types of passenger elevators, goods elevators and home elevators. Core contents include:

first, energy efficiency level upgrade, clarifying IE5 ultra-high energy efficiency as the minimum access standard, efficiency ≥96%, 40% energy saving compared with traditional asynchronous machines, standby energy consumption reduced by 70%, fully aligning with EU ErP and China Energy Label highest levels;

second, reliability and life, design life ≥30 years, bearing life ≥100,000 hours, insulation class Class H, temperature resistance 180℃, adapting to extreme environments of -20℃~60℃, passing special tests of 1000-hour continuous full load, thermal shock, vibration fatigue;

third, structure and performance specification, adopting gearless, direct drive, low noise, low vibration design, operating noise ≤55dB, vibration acceleration ≤0.1g, equipped with intelligent control system of high-precision encoder, temperature monitoring, overload protection, demagnetization protection;

fourth, materials and environmental protection, adopting high-grade rare earth permanent magnet materials, high-strength silicon steel sheets, environmentally friendly insulating paint, complying with EU ROHS, REACH environmental requirements, permanent magnet anti-demagnetization and anti-corrosion life ≥20 years;

fifth, testing and certification system, formulating full standards for energy efficiency testing, load testing, temperature rise testing, noise testing, reliability testing, must pass third-party authoritative testing, qualified type test before leaving factory.


After implementation, this standard will comprehensively improve the technical level of China's elevator core components, promote elevator machine energy efficiency and quality upgrade, providing Chinese technical standards for global elevator high-efficiency drive systems.
