JB/T 5275-1991 YW series and Y-WF series outdoor and outdoor chemical corrosion-resistant three-phase asynchronous motor technical conditions (frame size 80 ~ 315)

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. Anti-strong corrosion type (Y-WF2).

JB5275--91
This standard specifies the type, basic parameters and gauges, technical requirements, test methods and inspections of outdoor and outdoor anti-corrosion three-phase asynchronous motors (hereinafter referred to as motors) rules and requirements such as marking and packaging. This standard is applicable to motors used outdoors and in outdoor corrosive environments. According to the severity of the chemical media that they can withstand, they are divided into outdoor anti-light corrosion type (YW), outdoor anti-moderate corrosion type (Y-WFI) and outdoor anti-light corrosion type (Y-WFI). Anti-strong corrosion type (Y-WF2) 2 cited standards

3.1 The motor shell protection level should not be lower than IP54 (See GB4942.1). If you need to order a motor with a shell protection level higher than TP54, the user should consult with the manufacturer.
3.2 The cooling method of the motor is IC0141 (see GB1993). For IMB3, IMB5, IMB6, IMB7, IMB8, IMB35, IMV1, IMV3, IMV5, IMV6, IMV15 and IMV36 (see GB997), they are manufactured according to the provisions of Table 1. 3.4 The rating of the motor is based on the continuous working system (S1). Continuous rating. 3.5 The rated frequency of the motor is 50Hz and the rated voltage is 380V. The power is Y connection and the other power is Z connection.
