Beckman Industrial Doric 400A Indicator 400A-1-1-05-01 400A110501 100/125 VAC諧波電磁噪聲與震動 
　　普通異步電動機采用變頻器供電時，會使由電磁、機械、通風等因素所引起的震動和噪聲變的更加復雜。變頻電源中含有的各次時間諧波與電動機電磁部分的固有空間諧波相互干涉，形成各種電磁激振力。當電磁力波的頻率和電動機機體的固有振動頻率*或接近時，將產生共振現象，從而加大噪聲。由于電動機工作頻率范圍寬，轉速變化范圍大，各種電磁力波的頻率很難避開電動機的各構件的固有震動頻率。　
　 
        4、電動機對頻繁啟動、制動的適應能力 
　　由于采用變頻器供電后，電動機可以在很低的頻率和電壓下以無沖擊電流的方式啟動，并可利用變頻器所供的各種制動方式進行快速制動，為實現頻繁啟動和制動創造了條件，因而電動機的機械系統和電磁系統處于循環交變力的作用下，給機械結構和絕緣結構帶來疲勞和加速老化問題。 

         5、低轉速時的冷卻問題 
　　 首先，異步電動機的阻抗不盡理想，當電源頻率較底時，電源中高次諧波所引起的損耗較大。其次，普通異步電動機再轉速降低時，冷卻風量與轉速的三次方成比例減小，致使電動機的低速冷卻狀況變壞，溫升急劇增加，難以實現恒轉矩輸出。
