This standard specifies the damp heat test method, technical requirements and inspection rules for rotating electrical machines used under general environmental conditions. This standard applies to all types of rotating electrical machines (except for micro-controlled electrical machines, hereinafter referred to as electrical machines). According to the provisions of GB 755, the relative humidity of the operating environment is: the average maximum relative humidity of the wettest month is 90%, and the average minimum temperature of the month is not higher than 25 ℃. Motors should meet the requirements of this standard.
