Scope

Scope: This standard specifies the types, basic parameters, and dimensions of the YBZP2 series explosion-proof frequency-controlled three-phase asynchronous motors (frame number 112~355) for lifting applications, as well as their technical requirements, test methods, inspection rules, and requirements for marking, packaging, and warranty periods. This standard applies to all lifting machinery and metallurgical auxiliary equipment equipped with the YBZP2 series explosion-proof frequency-controlled three-phase asynchronous motors (frame number 112~355) (hereinafter referred to as "motors"). All derivative series of this motor series can be referenced for implementation. Main technical content: Through the development of the YBZP2 series explosion-proof frequency-controlled three-phase asynchronous motors (frame number 112~355), the following key technical issues have been addressed: - Solved the longstanding problem that high-power motors with small center height could not be produced domestically in advanced foreign countries, reducing the material consumption of single-power motors, saving resources, and contributing to the advancement of the national economy; - Integrated high-performance and high-power density designs into the product, improving product structure, saving raw materials, and enhancing technical and economic efficiency, making the comprehensive performance of the YBZP2 series explosion-proof frequency-controlled three-phase asynchronous motors higher than international advanced levels; - This series of motors is derived from the T/CEEIA 308-2018 standard, with power ratings and installation dimensions identical to the YBZP2 series. Compared with GB/T 21972.1 and JB/T 12684-2016, the average reduction in center height for the same power rating is 1~2 mm; compared with equivalent high-quality foreign products, the average increase in power rating under the same center height is 2~4 grades. The maximum torque multiplier of the YBZP2 series mo
