GB/T 13957-2022 Translated English of Chinese Standard (GB/T 13957-2022, GBT13957-2022): Technical requirements for the fundamental series of three-phase large asynchronous motor [Buy--download True-PDF in 3-second: https://play.google.com/books > Sign in > This BOOK > "3-dots" > Export > Save as "*.pdf"]This document specifies the type, basic parameters and dimensions, technical requirements, inspection rules, test methods, as well as requirements for the marking, packaging and warranty period, of three-phase large asynchronous motor. This document applies to large-scale Y series four-pole and above general-purpose cage-rotor three-phase asynchronous motors and large-scale YR series four-pole and above general-purpose wound-rotor three-phase asynchronous motors. The center heights are 710 mm, 800 mm, 900 mm, 1 000 mm and 1 120 mm, respectively. It applies to large-scale YKS, YRKS series three-phase asynchronous motors as a reference. |
