数控机床所用直流主轴电动机大多采用直流电动机结构,但与普通直流电动机又有不同,所以不能套用直流电动机的标准,且没有相应国际标准及国外先进国家标准。本标准编写目的旨在使国内产品向国际水平靠拢,并能指导行业生产。本标准根据JB/T8832—1999《机床数字控制系统通用技术条件》要求,在国际电工委员会IEC60034-1《旋转电机定额与性能》(1996年版)和IEC72-1《旋转电机尺寸与功率等级》(1991年版)的基础上,参考国际著名大公司的产品样本并结合我国企业生产情况编制的,并尽可能与上述国际标准的有关规定保持一致。本标准于2001年6月首次发布。
Most of the DC spindle motors used in CNC machine tools adopt DC motor structure, but they are different from ordinary DC motors. Therefore, they can not be applied to the standard of DC motors and have no corresponding international standards or advanced foreign standards. The purpose of this standard is designed to bring domestic products closer to the international level, and can guide the industry. This standard according to JB / T8832-1999 “general technical requirements for machine tool digital control system” requirements, in the International Electrotechnical Commission IEC60034-1 “fixed and rotating electrical performance” (1996 version) and IEC72-1 “rotary motor size and power rating” ( 1991 edition), based on reference to the product samples of famous international companies combined with the production of enterprises in China prepared, and as much as possible with the relevant provisions of the international standards to be consistent. This standard was first released in June 2001.
