對機械設備的傷害
全壓直接起動時的起動轉矩大約為額定轉矩的2倍，這麼大的力矩突然加在靜止的機械設備上，會加速齒輪磨損甚至打齒、加速皮帶磨損甚至拉斷皮帶、加速風葉疲勞甚至折斷風葉等等。
軟起動的轉矩不會超過額定轉矩，上述弊端可以克服。
當採用減壓起動時，上述危害只有程度的降低；當採用軟起動時，上述危害幾乎消失；獨立變壓器供電方式直接起動只能在電網電壓波動方面有所緩解，而其它方面的危害都照樣存在。
超大型電動機的價值都很高，在生產中也都起著核心作用。它的一點故障便會造成很大的經濟損失，對它採用完善的保護是非常必要的。比如說對一臺電機我們不能指望它的各處絕緣都是一致的，可能在某一點就有個薄弱環節，出廠試驗時它能通過，但在長時間的衝擊下這個薄弱環節會逐漸首先顯露出來，使其壽命縮短。如果我們採取軟起動，則可以大大延長電機的使用壽命，這兩種方案哪一個合算呢？這是顯而易見的。
開關變壓器
當今傳動工程中常用的就是三相交流感應電動機。在許多場合中，由於其起動特性，這些電動機涌直接連接電源係統。如果直接在線起動，將會產生高達電機額定電流6倍的浪涌電流。該電流會使供電係統和串聯的開關設備過載。如果直接起動，也會產生較高的峰值轉矩，這種衝擊不但會對驅動電動機產生衝擊，而且也會使用機械裝置受損。例如：輔助動力傳送部（V形帶，齒輪）。為了降低直動電流，應使用起動輔助裝置，如起動用電抗器或自耦變壓器，但使用電抗器或自耦變壓器起動等常規方法只能逐步降低電壓，而軟起動器通過平滑升子電壓，可以實現無衝擊起動。因此，可以佳地保護電源係統以及電機。
HPMV中、高壓軟起動器是用多個可控硅串並聯而成，可以滿足不同的電流及電壓要求，控制可控硅的觸發角就可以控制輸出電壓的大小。當電機起動過程中，HPMV按照預先設定的起動曲線增加電機的端電壓使電機平滑加速，從而減少了電機起動時對電網、電機本身、相連設備的電氣及機械衝擊。當電機達到正常轉速後，旁路接觸器接通。電機起動完畢後，HPMV軟起動器繼續監控電機並提供故障保護。在軟停機時首先按照預先設定好的停機曲線平滑地降低電機的端電壓直到電機停機。軟停可以解決突然停機引起的水泵水錘現象及機械衝擊等相關問題。
HPMV中、高軟起動器的操作過程可以分為四過程：起動準備完成、起動過程、運行和停機過程。CPU對所有的過程都提供的保護。
