直線電機(jī)的控制和旋轉(zhuǎn)電機(jī)一樣。像無(wú)刷旋轉(zhuǎn)電機(jī)，動(dòng)子和定子無(wú)機(jī)械連接（無(wú)刷），不像旋轉(zhuǎn)電機(jī)的方面，動(dòng)子旋轉(zhuǎn)和定子位置保持固定，直線電機(jī)系統(tǒng)可以是磁軌動(dòng)或推力線圈動(dòng)（大部分定位系統(tǒng)應(yīng)用是磁軌固定，推力線圈動(dòng)）。用推力線圈運(yùn)動(dòng)的電機(jī)，推力線圈的重量和負(fù)載比很小。然而，需要高柔性線纜及其管理系統(tǒng)。用磁軌運(yùn)動(dòng)的電機(jī)，不僅要承受負(fù)載，還要承受磁軌質(zhì)量，但無(wú)需線纜管理系統(tǒng)。 </p> <p> 相似的機(jī)電原理用在直線和旋轉(zhuǎn)電機(jī)上。相同的電磁力在旋轉(zhuǎn)電機(jī)上產(chǎn)生力矩在直線電機(jī)產(chǎn)生直線推力作用。因此，直線電機(jī)使用和旋轉(zhuǎn)電機(jī)相同的控制和可編程配置。直線電機(jī)的形狀可以是平板式和U 型槽式，和管式.哪種構(gòu)造適合要看實(shí)際應(yīng)用的規(guī)格要求和工作環(huán)境。 </p><p> 直線電機(jī)工作基本原理 </p> <p> 直線電機(jī)不僅從結(jié)構(gòu)上是從旋轉(zhuǎn)電機(jī)演變而來(lái)的，其工作原理也與旋轉(zhuǎn)電機(jī)相似，遵循電機(jī)學(xué)的一些基本電磁原理。這里直流永磁直線電機(jī)為例子，說(shuō)明一下直線電機(jī)的基本工作原理。 </p> <p> 音圈電機(jī)，和直線電機(jī)在某種程度上是一致的。區(qū)別在于，音圈電機(jī)只有一個(gè)線圈，磁極一般不超過(guò)2對(duì)，只被要求在一對(duì)磁極的范圍里運(yùn)動(dòng)，也就不需要換相了。當(dāng)需要突破這種行程限制，就必需要有更多的磁極，和更多的線圈來(lái)接力，這就是直線電機(jī)。所以音圈電機(jī)也叫做無(wú)換向直線電機(jī)。
