This standard specifies the types, basic parameters and dimensions, technical requirements, inspection rules as well as marking and packaging requirements for large three-phase asynchronous motors.
This standard is applicable to general-purpose Y-series quadrupole or above three-phase large asynchronous motor with cage rotor (hereinafter referred to as Y-series motor) and general-purpose YR-series quadrupole or above three-phase large asynchronous motor with wound rotor (hereinafter referred to as YR-series motor), with the center height 710, 800, 900, 1000 and 1120 mm respectively. For YKS and YRKS series three-phase large asynchronous motors, this standard applies for reference.
Those not specified in this standard shall meet the relevant requirements of GB 755.
