Motor Description

SIMO made YE3 series W, WF chemical corrosion-resistant three phase asynchronous motor, if the ambient air temperature is required to be lower than -20℃ (-35℃or -50℃), the user shall negotiate with the manufacturer. The high relative humidity of the ambient air is 100%, and the high absolute humidity is 25g/m³. The ambient air velocity shall not exceed 30m/s and the air pressure shall not be lower than 90KPa. The maximum intensity of solar radiation is 1120 W/m2. Splash and rainfall are used in the service environment, and the maximum rainfall intensity is 6mm/min. There are ice, snow, frost and dew in the service environment. If rodents and other harmful animals (except termites) are used in the environment, molds and fungi are allowed for outdoor light corrosion protection products. 

The environmental condition grades of chemical active substances and mechanical active substances are 4C2 and 4s2 for outdoor W, 4C3 and 4S3 for WF1 and 4C4 and 4S4 for WF2. In case of special needs, other environmental conditions specified in JB4375 can be selected through negotiation between the user and the manufacturer.
