发电机额定电压指电机在额定工况下运行，其端子电压整流后并扣除连接线压降的直流输出电压。
Refers to the electrical generator rated voltage at rated operation conditions, the terminal voltage after the rectifier and the deduction of the DC link output voltage drop.
使用于交流额定电压450/750V及以下各种移动式电机、钢铁、航空、电厂、石化等高温环境中使用。
Used in AC rated voltage 450/750V and below a variety of mobile motors, steel, aviation, power plants, petrochemical and other high temperature environment.
电源电压应控制在不大于或小于额定电压的5%范围内，如果电压过高或过低都会损坏电机。
Supply voltage should be controlled at not more than or less than 5% of rated voltage range, if the voltage too high or too low will damage motor.
