-我退出了。 带励磁绕组的同步电机的要求包含在以下三个美国国家标准中:美国国家标准同步电机通用要求C50。10-1977. 美国国家标准对圆柱转子同步发电机的要求，C50。13-1977. 美国国家标准《燃气轮机驱动同步发电机的要求》，C50。14-1977. 本标准包含适用于所有类型60 Hz同步电机（分数马力电机除外）的一般要求和定义。圆柱转子同步发电机和燃气轮机驱动同步发电机的具体要求见美国国家标准C50。 13-1977和C50。14-1977.

- Inactive-Withdrawn. The requirements for synchronous machines with excitation windings are covered by three American National Standards as follows: American National Standard General Requirements for Synchronous Machines, C50.10-1977. American National Standard Requirements for Cylindrical Rotor Synchronous Generators, C50.13-1977. American National Standard Requirements for Combustion Gas Turbine Driven Synchronous Generators, C50.14-1977. This standard contains general requirements and definitions applicable to all types of 60 Hz synchronous machines except fractional horsepower motors. Specific requirements for cylindrical rotor synchronous generators and combustion gas turbine driven synchronous generators will be found in American National Standards C50.13-1977 and C50.14-1977.
