GB/T 21972.2-2023 Technical specification for variable-frequency adjustable-speed three-phase induction motors for crane and metallurgical applications—Part 2:YZP series variable-frequency adjustable-speed three-phase induction motors for crane and metallurgical applications(cooled with axial fan)(frame size 100～400）
Abstract
This document specifies the types, basic parameters, and dimensions of the YZP series frequency-controlled three-phase asynchronous motors for lifting and metallurgical applications (cooled by axial-flow fans) (with base numbers 100~400), as well as their technical requirements, test methods, inspection rules, and marking, packaging, and warranty period. This document applies to axial-flow fan-cooled three-phase asynchronous motors (with base numbers 100~400) used in power transmission for various lifting machinery and metallurgical auxiliary equipment powered by frequency converters.
