前言单相串励电动工具的主要部件——定子、转子是电动工具的心脏,它的质量对电动工具安全及寿命的影响极大。目前,我国制造定子、转子的专业生产厂日趋增多,但没有一个统一标准检查。因此,本标准根据实际需要,对定子、转子最基本的安全及制造质量作了规定,以促进定子、转子的专业化生产和质量的提高。
Introduction The main components of a single-phase series-excited power tool, the stator and rotor, are the heart of the power tool. Its quality has a great influence on the safety and life of the power tool. At present, there are more and more professional manufacturers of stators and rotors manufactured in China, but there is no unified standard inspection. Therefore, according to actual needs, this standard specifies the basic safety and manufacturing quality of stators and rotors to promote professional production and quality improvement of stators and rotors.
