《GB/T 4997-2008永磁式低速直流测速发电机通用技术条件》由TC2(全国微电机标准化技术委员会)归口,主管部门为中国电器工业协会。
本标准代替GB/T4997―1993《永磁式低速直流测速发电机通用技术条件》。本标准规定了永磁式低速直流测速发电机的型号和机座号、运行条件、技术要求和试验方法、试验条件、检验规则及交付准备。本标准适用于永磁式低速直流测速发电机。本标准应与永磁式低速直流测速发电机(以下简称电机)产品专用技术条件一起使用。与GB/T4997―1993相比主要变化如下:
―――按照GB/T1.1―2000《标准化工作导则 第1部分:标准的结构和编写规则》的规定,并为了
与相关标准协调一致,在条款编排上进行了比较大的调整;
―――标准覆盖机座号范围扩大,由55~320扩大至45~750。


Scope

This standard specifies the type and frame size, operating conditions, technical requirements, test methods, test conditions, inspection rules and delivery preparations of permanent magnet low-speed DC tachogenerators. This standard applies to permanent magnet low-speed DC tachogenerators. This standard should be used together with the special technical conditions for permanent magnet low-speed DC tachogenerators (hereinafter referred to as motors).
