消除直流電機(jī)電磁干擾的有效方法
　　電磁干擾的危害和電磁兼容
　　電磁干擾是人們?cè)缇桶l(fā)現(xiàn)的電磁現(xiàn)象。一些電器、電子設(shè)備工作時(shí)所產(chǎn)生的電磁波，容易對(duì)周圍的其他電氣、電子設(shè)備形成電磁干擾，引發(fā)故障或者影響信號(hào)的傳輸。另外，過(guò)度的電磁干擾會(huì)形成電磁污染，危害人們的身體健康，破壞生態(tài)平衡。
　　通常認(rèn)為電磁干擾傳輸有兩種方式：一種是傳導(dǎo)方式;另一種是輻射方式。在實(shí)際工程中，兩個(gè)設(shè)備之間發(fā)生干擾通常包含著許多種途徑的耦合。正因?yàn)槎喾N途徑的耦合同時(shí)存在，反復(fù)交叉，共同產(chǎn)生干擾，才使得電磁干擾變得難以控制。

減速器是原動(dòng)機(jī)和工作機(jī)之間的獨(dú)立的閉式傳動(dòng)裝置，用來(lái)降低轉(zhuǎn)速和增大轉(zhuǎn)矩，以滿足工作需要，在某些場(chǎng)合也用來(lái)增速，稱為增速器。
選用減速器時(shí)應(yīng)根據(jù)工作機(jī)的選用條件，技術(shù)參數(shù)，動(dòng)力機(jī)的性能，經(jīng)濟(jì)性等因素，比較不同類型、品種減速器的外廓尺寸，傳動(dòng)效率，承載能力，質(zhì)量，價(jià)格等，選擇的減速器。 [編輯本段]減速器分類 減速器的類別、品種、型式很多，目前已制定為行（國(guó)）標(biāo)的減速器有40余種。減速器的類別是根據(jù)所采用的齒輪齒形、齒廓曲線劃分；減速器的品種是根據(jù)使用的需要而設(shè)計(jì)的不同結(jié)構(gòu)的減速器；減速器的型式是在基本結(jié)構(gòu)的基礎(chǔ)上根據(jù)齒面硬度、傳動(dòng)級(jí)數(shù)、出軸型式、裝配型式、安裝型式、聯(lián)接型式等因素而設(shè)計(jì)的不同特性的減速器。
減速器的載荷分類
與減速器聯(lián)接的工作機(jī)載荷狀態(tài)比較復(fù)雜，對(duì)減速器的影響很大，是減速器選用及計(jì)算的重要因素，減速器的載荷狀態(tài)即工作機(jī)（從動(dòng)機(jī)）的載荷狀態(tài)，通常分為三類：
①—均勻載荷;
②—中等沖擊載荷;
③—強(qiáng)沖擊載荷。
