This standard specifies the types, basic parameters and dimensions, technical requirements, test methods and inspection rules, as well as marking and packaging requirements for outdoor and outdoor corrosion-resistant three-phase asynchronous motors. This standard applies to motors used outdoors and in outdoor corrosive environments. Motors are divided into outdoor light corrosion-resistant type (YW), outdoor medium-corrosion resistant type (Y-WF1) and outdoor based on the severity of the environmental chemical media they can withstand. Strong corrosion resistance type (Y-WF2).
