高壓電機(jī)直接啟動就是在全電壓條件下直接啟動電機(jī)。如果電網(wǎng)條件允許，可以采用直接啟動。但在實際生產(chǎn)過程中往往由于電網(wǎng)容量有限，很少采用直接啟動。由于采用直接啟動時，湖北電機(jī)生產(chǎn)，啟動電流大，使電壓下降幅度較大，對于供電系統(tǒng)有較大的沖擊，如果壓降超過一定值，有可能導(dǎo)致上級變電所跳閘。故在實際運行中很少采用這種直接啟動方法。串聯(lián)電抗器啟動就是在電機(jī)啟動的時候串入電抗器，以限制和降低電機(jī)啟動時的啟動電流及電網(wǎng)壓降，當(dāng)電機(jī)運行穩(wěn)定且電流達(dá)到一定值時，切除電抗器變?yōu)殡姍C(jī)直接啟動模式，湖北電機(jī)生產(chǎn)。由于啟動過程中電機(jī)端的電壓也下降，容易導(dǎo)致啟動轉(zhuǎn)矩不夠，在啟動過程中還會出現(xiàn)一個二次沖擊的過程。自耦變壓器啟動是指電動機(jī)啟動時利用自耦變壓器來降低加在電動機(jī)定子繞組上的啟動電壓。待電動機(jī)啟動后，湖北電機(jī)生產(chǎn)，再使電動機(jī)與自耦變壓器脫離，從而在全壓下正常運行。優(yōu)點是可以按容許的啟動電流和所需的啟動轉(zhuǎn)矩來選擇自耦變壓器副邊的不同抽頭實現(xiàn)降壓啟動，而且不論電動機(jī)定子繞組采用星形接法或三角形接法都可以使用。缺點是設(shè)備的體積較大，因而成本較貴。

電機(jī)是把電能轉(zhuǎn)換成機(jī)械能的機(jī)電設(shè)備。電網(wǎng)輸入的電能經(jīng)電機(jī)內(nèi)部氣隙磁場實現(xiàn)機(jī)電能量轉(zhuǎn)換，由電機(jī)軸伸輸出機(jī)械功率驅(qū)動各類設(shè)備運轉(zhuǎn)。通俗點講，電機(jī)內(nèi)氣隙是電能轉(zhuǎn)換為機(jī)械能的無形媒介，軸伸則是電機(jī)與機(jī)械傳動系統(tǒng)的有形聯(lián)結(jié)。下面，就和大家聊聊電機(jī)與機(jī)械傳動系統(tǒng)聯(lián)結(jié)型式，各類聯(lián)結(jié)究竟有哪些特點，為什么必須選擇這種聯(lián)結(jié)方式。電機(jī)與機(jī)械傳動系統(tǒng)聯(lián)結(jié)方式理論上可以有可拆卸和不可拆卸兩大類，但幾乎所有應(yīng)用系統(tǒng)中電機(jī)作為通用性**模塊存在，必須具有互換性，故而只有可拆卸聯(lián)結(jié)結(jié)構(gòu)型式。恰恰因可拆卸、互換性這一基本特征，電機(jī)軸伸才只有圓柱軸伸、圓錐軸伸、花鍵軸伸三種，實際輸出聯(lián)結(jié)形式分為圓柱軸伸平鍵聯(lián)結(jié)、圓錐軸伸平鍵聯(lián)結(jié)、圓柱軸伸切向鍵聯(lián)結(jié)和花鍵聯(lián)結(jié)，其中花鍵聯(lián)結(jié)時根據(jù)負(fù)荷和精度要求設(shè)計為矩形花鍵軸伸和漸開線花鍵軸伸。
