消除直流电机电磁干扰的有效方法
电磁干扰的危害和电磁兼容
电磁干扰是人们早就发现的电磁现象。一些电器、电子设备工作时所产生的电磁波，容易对周围的其他电气、电子设备形成电磁干扰，引发故障或者影响信号的传输。另外，过度的电磁干扰会形成电磁污染，危害人们的身体健康，破坏生态平衡。
通常认为电磁干扰传输有两种方式：一种是传导方式;另一种是辐射方式。在实际工程中，两个设备之间发生干扰通常包含着许多种途径的耦合。正因为多种途径的耦合同时存在，反复交叉，共同产生干扰，才使得电磁干扰变得难以控制。

也就是说这个梅花扳手的内孔对方是17MM的。是怎么算的规格和测量出来的规格？螺栓与螺帽的尺寸关系是人为规定的，有一部分是1.5的关系，也就是说螺纹公称直径×1.5是螺帽对边。测量螺母、螺帽、扳手的对边。螺母、螺帽的对边尺寸是人为规定的。梅花内六角扳手T3代表什么T代表什么3代表什么？T是TORX的个字母3是外径的通称规格，T3的外径是5.94。热点关注：热点专题电动工具品牌之牧田：只为人士而生热点专题一机在手木作不愁：木工木作工具选购攻略热点资讯油锯启动不了或熄火的原因是是什么？看完这你就知道了五金百科你用的油锯老坏是怎么了？肯定是保养不当。

减速器是原动机和工作机之间的独立的闭式传动装置，用来降低转速和增大转矩，以满足工作需要，在某些场合也用来增速，称为增速器。
选用减速器时应根据工作机的选用条件，技术参数，动力机的性能，经济性等因素，比较不同类型、品种减速器的外廓尺寸，传动效率，承载能力，质量，价格等，选择的减速器。 [编辑本段]减速器分类 减速器的类别、品种、型式很多，目前已制定为行（国）标的减速器有40余种。减速器的类别是根据所采用的齿轮齿形、齿廓曲线划分；减速器的品种是根据使用的需要而设计的不同结构的减速器；减速器的型式是在基本结构的基础上根据齿面硬度、传动级数、出轴型式、装配型式、安装型式、联接型式等因素而设计的不同特性的减速器。
减速器的载荷分类
与减速器联接的工作机载荷状态比较复杂，对减速器的影响很大，是减速器选用及计算的重要因素，减速器的载荷状态即工作机（从动机）的载荷状态，通常分为三类：
①—均匀载荷;
②—中等冲击载荷;
③—强冲击载荷。
