【正文】 nt magnetism ferrites, because such material remanence high, reconstruction seek power, magnetic energy from large, fully able to meet medium and small electrical performance requirements, with cheaper prices. German visitors to the permanent magnetism slowdown electrical materials are generally used such ferrites permanent magnetism. Planetary gear, plus a sophisticated powder metallurgy and manufacturing technology and its advantages : a. Slowdown gear 。b reduced weight. Armature imbalance of the move greatly reduced because of the moving armature imbalances and armature weight proportional 。 隨著起動(dòng)機(jī)的新設(shè)計(jì)、新結(jié)構(gòu)的采納，新工藝、新材料的應(yīng)用，新裝置、新構(gòu)想的實(shí)現(xiàn)，將把新型起動(dòng)機(jī)、新型汽車推向新的理想境地。 行星齒輪和內(nèi)齒輪采用精密的粉末冶金技術(shù)制造，其優(yōu)越性：；；；、噪音更小。 起動(dòng)機(jī)的設(shè)計(jì)和制造不斷地向前發(fā)展，特別是轎車起動(dòng)機(jī)出現(xiàn)了多次劃時(shí)代的變革。因?yàn)橛来烹姍C(jī)的磁場(chǎng)強(qiáng)度低于電激磁電機(jī)，沖孔后的電樞軛對(duì)永磁電機(jī)的磁性能影響不大。汽車起動(dòng)機(jī)將主要朝以下幾個(gè)方面發(fā)展： 1．隨著微型車、重型車比重的擴(kuò)大，起動(dòng)機(jī)也會(huì)在19KW的功率等級(jí)上有新發(fā)展，中、小型功率起動(dòng)機(jī)將以永磁式行星齒輪減速為主，大功率起動(dòng)機(jī)將以電激磁式行星齒輪減速型方向發(fā)展。 象中汽長(zhǎng)電股份有限公司從20世紀(jì)80年代后期開(kāi)始生產(chǎn)減速起動(dòng)機(jī)，已經(jīng)有15年以上的設(shè)計(jì)和生產(chǎn)經(jīng)驗(yàn)，并且從國(guó)外（如德國(guó)、韓國(guó)、日本）引進(jìn)了從加工、焊接、轉(zhuǎn)子生產(chǎn)線、總裝配，到測(cè)試技術(shù)等大批具有90年代國(guó)際先進(jìn)水平的轎車電器生產(chǎn)的成套設(shè)備。b improve precision. 。 Increase the export of power and torque, improved startup performance, the extension of life expectancy, etc. superiority. In the design and manufacture of cranes continue to develop, particularly the emergence of a number of cars belonging landmark change. 20th century Japan in the 1970s appeared in the two axis of increase magnetism slowdown start, allowing greatly reduced the weight of the cranes, one Taiwan 12V, the power increase magnetism 2KW slowdown start to weight, and the traditional power equal weight is to start . 1980s produced featurestyle permanent magnetism slowdown start, it has two advantages keen slowdown start, but in shape, simulating traditional start to the small size, light weight, great power, delicate appearance and widely used in cars. Permanent magnetism start of the 1990s slowdown lighter, more than power. Key measure is to reduce the armature weight in the Department of Electrical horse jumped a larger Kong. Because the magnetic field intensity lower than permanent magnetism electrical power increase magnetism electrical, accessible to the armature perform permanent magnetism to electrical magnetic little impact. But advantages are manifold : a. 。這種42V供電系統(tǒng)是通過(guò)一個(gè)14V/42V的轉(zhuǎn)換裝置來(lái)實(shí)現(xiàn)的。德國(guó)博世的永磁減速電機(jī)基本上都采用這種鐵氧體永磁材料。減速電機(jī)有電激磁減速和永磁減速兩種，而采用永磁減速更能減小體積、減輕重量、提高比功率；降低成本、提高工效、增加收益；增加功率和扭矩的輸出，改善起動(dòng)性能，延長(zhǎng)壽命等的優(yōu)越性。但優(yōu)點(diǎn)卻是多方面的：；，因?yàn)殡姌械膭?dòng)不平衡與電樞的重量成正比；，而使電機(jī)的性能可靠、噪音小、壽命延長(zhǎng)。 2．轎車用的起動(dòng)機(jī)要在現(xiàn)有基礎(chǔ)上進(jìn)一步優(yōu)化電磁設(shè)計(jì)和結(jié)構(gòu)設(shè)計(jì)，加大減速比，將減速比提高到5以上，應(yīng)用新材料、新結(jié)構(gòu)，在原有體積和基礎(chǔ)上減輕重量，提高輸出功率和扭矩，增加比功（KW/kg），使比功在現(xiàn)有基礎(chǔ)再提高15%以上。而且大部分為永磁減速起動(dòng)機(jī)。c work efficiency. 。 Reducing costs, improving ergonomics and increase revenue。 與這種一體化系統(tǒng)裝置同時(shí)開(kāi)發(fā)的將是一種42V車用供電系統(tǒng)，將極好的滿足汽車用電負(fù)荷增加的需要。
