電工鋼硅鋼片In addition to the types listed above, there are also some special purpose electrical steel plates, such as 0.15 and 0.20mm thick 3％ Si cold-rolled non oriented silicon steel strips and 0.025, 0.05, and 0.1mm thick 3％ Si cold-rolled oriented silicon steel strips, used for medium and high-frequency motors, transformers, and pulse transformers； 0.7mm thick 3％ Si high-strength cold-rolled non oriented silicon steel plate for relays and power switches； High strength cold-rolled electrical steel plate for new high-speed motor rotors； Low carbon electrical steel hot-rolled thick and cold-rolled plates for magnetic shielding and high-energy accelerator electromagnets such as medical magnetic resonance tomography scanners； 4.5％ to 6.5％ Si high silicon steel plates for high-frequency motors, transformers, and magnetic shielding.Generally, motors, transformers, and other electrical components are required to have high efficiency, low power consumption, small size, and light weight. Electrical steel plates are usually guaranteed to have magnetic properties based on core loss and magnetic induction strength [1] [2]. The requirements for the performance of electrical steel plates are as follows:Low core loss (PT)Iron core loss refers to the ineffective electrical energy consumed by an iron core when magnetized in an alternating magnetic field of ≥ 50Hz, abbreviated as iron loss, also known as alternating loss, and its unit is W/kg. The ineffective electrical energy consumed due to various obstacles caused by magnetic flux changes not only loses electrical energy through the heating of the iron core, but also causes temperature rise of the motor and transformer. The iron loss (PT) of electrical steel includes three parts: hysteresis loss, eddy current loss (Pe), and anomalous loss (Pa). Electrical steel plates have low iron loss, which can save a lot of electricity, prolong the operating time of motors and transformers, and simplify cooling devices. Due to the iron loss of electrical steel plates, which accounts for 2.5％ to 4.5％ of the annual electricity generation in various countries, countries always try their best to reduce iron loss in the production of electrical steel plates, and use iron loss as the most important indicator to assess the magnetic properties of products. The iron loss value of products is used as the basis for classifying product grades. Cold rolled oriented electrical steel: Cold rolled oriented electrical steel is a high-end product in the field of electrical steel. Compared with cold rolled non oriented electrical steel, its magnetism has strong directionality； It has superior high magnetic permeability and low loss characteristics in the direction of easy magnetization rolling. The iron loss of oriented steel strip in the rolling direction is only 1/3 of that in the transverse direction, and the ratio of magnetic permeability is 6:1. Application: The main purpose of cold-rolled oriented silicon steel strip is for transformer manufacturing.Full process cold rolled non oriented silicon steel coating: The surface of the full process cold rolled silicon steel is coated with a semi transparent insulation coating, which has different codes in different standards.

電工鋼硅鋼片汽車驅(qū)動(dòng)電機(jī)鐵芯的介紹電動(dòng)汽車是以電驅(qū)動(dòng)為基礎(chǔ)的、四川綿陽同城經(jīng)濟(jì)、四川綿陽同城清潔的綠色交通工具，在能源、四川綿陽同城環(huán)境等方面具有＊的競(jìng)爭(zhēng)力，而且能夠方便地采用現(xiàn)代控制技術(shù)實(shí)現(xiàn)其機(jī)電一體化，具有廣闊的發(fā)展前景。汽車驅(qū)動(dòng)電機(jī)鐵芯的電機(jī)驅(qū)動(dòng)系統(tǒng)是電動(dòng)汽車的動(dòng)力源，是決定汽車運(yùn)行各項(xiàng)性能指標(biāo)的主體與內(nèi)在根據(jù)。目前，電動(dòng)汽車電機(jī)主要有直流電機(jī)、四川綿陽同城感應(yīng)電機(jī)、四川綿陽同城永磁無刷電機(jī)以及開關(guān)磁阻電機(jī)等。汽車驅(qū)動(dòng)電機(jī)鐵芯永磁無刷電機(jī)可分為兩類：一類是具有正弦波電流的永磁同步電機(jī)，另一類是具有矩形脈沖波電流的無刷直流電機(jī)。兩種電機(jī)，轉(zhuǎn)子都是磁體，電機(jī)轉(zhuǎn)子不需要電刷和勵(lì)磁繞組，通過定子繞組換相產(chǎn)生旋轉(zhuǎn)轉(zhuǎn)矩。由于轉(zhuǎn)子沒有勵(lì)磁繞組，無銅耗，磁通小，在低負(fù)荷時(shí)鐵耗很小，因此，永磁無刷電機(jī)具有高的“功率/質(zhì)量”比，可以高速運(yùn)轉(zhuǎn)，同時(shí)由于沒有轉(zhuǎn)子的磨損且定子繞組是主要的發(fā)熱源，易于冷卻。汽車驅(qū)動(dòng)電機(jī)鐵芯的特性；汽車驅(qū)動(dòng)電機(jī)鐵芯的永磁無刷電機(jī)可靠性高，輸出功率大，與相同轉(zhuǎn)速的其他電機(jī)相比具有體積小，質(zhì)量輕，便于維修，率，高功率因數(shù)等特點(diǎn)。 轉(zhuǎn)子電磁時(shí)間常數(shù)小，電機(jī)動(dòng)態(tài)特性好，通過調(diào)節(jié) 導(dǎo)通角，可以實(shí)現(xiàn)恒功率運(yùn)行，通過優(yōu)化控制 角還可以優(yōu)化電機(jī)的效率，從而得到較寬的恒功率運(yùn)行區(qū)以及較高的效率。電機(jī)高速?zèng)_定轉(zhuǎn)子鐵芯的概述當(dāng)前國內(nèi)外電機(jī)高速?zèng)_定轉(zhuǎn)子鐵芯的電機(jī)工藝技術(shù)的發(fā)展很快,隨著沖壓設(shè)備的吏新,國內(nèi)外為電機(jī)高速?zèng)_定轉(zhuǎn)子鐵芯的電機(jī)沖片的生產(chǎn)提供了高質(zhì)量、四川綿陽同城率、四川綿陽同城高精度的新型設(shè)備,它帶來了電機(jī)沖片工藝技術(shù)為此,與之相適應(yīng)的新工藝裝備的設(shè)計(jì)技術(shù)已成為人們研究的新課題。電機(jī)高速?zèng)_定轉(zhuǎn)子鐵芯的定子沖片沖槽同時(shí)分離轉(zhuǎn)子沖片和轉(zhuǎn)子沖片沖槽同時(shí)切氣隙是應(yīng)用于高速?zèng)_槽機(jī)上的新的工藝方案,該方案在國外已被廣泛應(yīng)用,國內(nèi)電機(jī)行業(yè)剛開始研究和應(yīng)用,故為實(shí)現(xiàn)該工藝按所需工藝裝備的設(shè)計(jì)技術(shù)作一些探討。電機(jī)高速?zèng)_定轉(zhuǎn)子鐵芯的影響：電機(jī)高速?zèng)_定轉(zhuǎn)子鐵芯的電機(jī)沖片工藝技術(shù)在新品開發(fā)中的影響我國電機(jī)沖片傳統(tǒng)工藝為復(fù)式?jīng)_槽和單式?jīng)_槽兩大類,現(xiàn)分析如下:1)復(fù)式?jīng)_槽工藝方案:該方案沖片槽形整齊度好,工序少,工裝少,但工裝復(fù)雜精度要求高,設(shè)備條件要好,工裝制造周期長(zhǎng),成本高,只適用于批量生產(chǎn),不利于新品開發(fā)和小批試制。2)單式?jīng)_槽工藝方案:該方案沖片槽形整齊度差,工序多,工裝多,設(shè)備多,工裝較簡(jiǎn)單,質(zhì)量不穩(wěn)定,生產(chǎn)周期長(zhǎng),成本高,只適用于中、四川綿陽同城小批生產(chǎn)。電機(jī)高速?zèng)_定轉(zhuǎn)子鐵芯的要求：1、四川綿陽同城定位精度要求。該工藝方案中沖槽分離和沖槽切氣隙兩道復(fù)合工序,要求同一定位基準(zhǔn),確保定、四川綿陽同城轉(zhuǎn)子槽形,外圓鳩尾槽、四川綿陽同城軸孔的同心度不大于0.02mm,中心孔定位滿足同心度的技術(shù)要求,小側(cè)孔與中心孔聯(lián)合定位滿足周向方位度的要求。2、四川綿陽同城復(fù)合工序精度要求。沖槽分離復(fù)合工序:該工序有槽形凸模和切口凸模來完成級(jí)進(jìn)沖裁工藝,該工序先沖槽后切口分離定、四川綿陽同城轉(zhuǎn)子沖片,兩凸模在同一圓心軌跡上同步動(dòng)作,兩凸模之間的中心夾角為槽形中心夾角的一倍半,該工藝裝備應(yīng)用在高速?zèng)_槽機(jī)上,其槽形分度精度由設(shè)備上弧面凸輪式步進(jìn)機(jī)構(gòu)來保證；
