SPG可逆馬達(dá) S9I180GACE SPG工廠直銷3、諧波鐵損電機(jī)中的鐵心損耗也由于電源電壓中出現(xiàn)諧波而增大；定子電流的各次諧波在氣隙間建立了時(shí)間諧波磁動勢。氣隙中任何一點(diǎn)的總磁勢是基波和時(shí)間諧波磁勢的合成。對于一個(gè)三相6階梯電壓波形，氣隙中的磁密峰值比基波值約大10％，但是由時(shí)間諧波磁通引起的鐵損的增加是很小的。對于端部漏磁通和斜槽漏磁通產(chǎn)生的雜散損耗，在諧波頻率作用下將有所增加，這一點(diǎn)在非正弦供電時(shí)必須考慮：端部漏磁效應(yīng)在定子和轉(zhuǎn)子繞組中都存在，主要是漏磁通進(jìn)入端板引起的渦流損耗。由于定子磁勢和轉(zhuǎn)子磁勢間相位差的變化，在斜槽結(jié)構(gòu)中產(chǎn)生斜槽漏磁通，其磁勢在端部zui大，在定轉(zhuǎn)子鐵心及齒中產(chǎn)生損耗。

SPG減速機(jī)適用于伺服電機(jī)SPG精密行星減速機(jī)，具有高精度，高剛性結(jié)構(gòu)設(shè)計(jì)，可以為客戶提供超乎想象的強(qiáng)勁技能與性能。下面先簡單介紹選型減速電機(jī)

SPG是韓國品牌小型減速電機(jī)，產(chǎn)品規(guī)格齊全，品種繁多。主要使用于精密機(jī)械、自動化設(shè)備、電子機(jī)械、自動門窗、自動麻將、印刷機(jī)械、包裝機(jī)械、影像機(jī)械、室內(nèi)外廣告機(jī)械、醫(yī)療用機(jī)械設(shè)備，空調(diào)、復(fù)印機(jī)、打印機(jī)、攪拌器、刨冰器、電冰箱、自動化工廠生產(chǎn)流水線等，尤其在注重高精度一體化自動化設(shè)備的行業(yè)中占有十分重要的地位。 談及永磁同步電動機(jī)，字面上可能更好理解，所謂永磁，是指在制造電機(jī)轉(zhuǎn)子時(shí)加入永磁體，使電機(jī)的性能得到進(jìn)一步的提升。此前磁鐵性能不好，但是“萬磁王”高磁性能釹鐵硼在控制算法下的穩(wěn)定性能和廣泛應(yīng)用，增加了永磁體的可靠性與穩(wěn)定性，可以較好地減少退磁現(xiàn)象的發(fā)生。而所謂同步，則指的是轉(zhuǎn)子的轉(zhuǎn)速與定子繞組的電流頻率始終保持一致。稀土永磁部件目前驅(qū)動電機(jī)主要分為直流電機(jī)、交流電機(jī)及輪轂電機(jī)等；其中，直流和交流電機(jī)又可進(jìn)一步劃分。目前行業(yè)對交流異步電機(jī)、永磁同步電機(jī)及開關(guān)磁阻電機(jī)關(guān)注度較高。通過對常見的幾種電機(jī)進(jìn)行比較分析可知（見表1），永磁同步電機(jī)具有效率高、轉(zhuǎn)速范圍寬、體積小、重量輕、功率密度大、成本低等優(yōu)點(diǎn)，成為純電動乘用車市場的主要驅(qū)動電機(jī)。 從行業(yè)配套來看，新能源乘用車主要使用的是交流感應(yīng)電機(jī)和永磁同步電機(jī)。其中，永磁同步電機(jī)使用較多，因其轉(zhuǎn)速區(qū)間和效率都相對較高，但是需要使用昂貴的系統(tǒng)永磁材料釹鐵硼；部分歐美車系采用交流感應(yīng)電機(jī)，主要因?yàn)橄⊥临Y源匱乏，同時(shí)出于降低電機(jī)成本考慮，其劣勢主要是轉(zhuǎn)速區(qū)間小，效率低，需要性能更高的調(diào)速器以匹配性能。 隨著新能源汽車市場的迅猛發(fā)展，驅(qū)動電機(jī)市場空間潛力巨大，吸引了眾多企業(yè)和資本的進(jìn)入。國內(nèi)外典型驅(qū)動電機(jī)企業(yè)的永磁同步電機(jī)產(chǎn)品情況如表2所示。整體來看，我國驅(qū)動電機(jī)取得較大進(jìn)展，已經(jīng)自主開發(fā)出滿足各類新能源汽車需求的產(chǎn)品，部分主要性能指標(biāo)已達(dá)到相同功率等級的國際先進(jìn)水平。但是在峰值轉(zhuǎn)速、功率密度及效率方面與國外仍存在一定的差距 永磁同步電機(jī)在生產(chǎn)工藝方面的難點(diǎn)是制約大規(guī)模配套乘用車的重要因素。因?yàn)橛来磐诫姍C(jī)生產(chǎn)企業(yè)缺乏產(chǎn)業(yè)化的積累，國內(nèi)企業(yè)生產(chǎn)不良率較高，無法達(dá)到乘用車企業(yè)的不良率要求，尤其是隨著純電動乘用車市場規(guī)模的擴(kuò)大，十萬級的年產(chǎn)量給永磁同步電機(jī)帶來了巨大的挑戰(zhàn)。
