Scope

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 (hereinafter referred to as “Y series
motors”) and large-scale YR series four-pole and above general-purpose wound-rotor
three-phase asynchronous motors (hereinafter referred to as “YR series 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.
