GB/T 21972.3-2023 Technical specification for variable-frequency adjustable-speed three-phase induction motors for crane and metallurgical applications—Part 3:YZP series variable-frequency adjustable-speed three-phase induction motors for crane and metallurgical applications
Abstract
This document specifies the types, basic parameters, and dimensions of YZP series frequency-controlled three-phase asynchronous motors for lifting and metallurgy (centrifugal fan cooling) (frame numbers 100 to 400), as well as their technical requirements, test methods, inspection rules, and marking, packaging, and warranty period. This document applies to centrifugal fan-cooled three-phase asynchronous motors (frame numbers 100 to 400) used for power transmission in various lifting machinery and metallurgy auxiliary equipment powered by frequency converters.
