　　八、電動機過熱甚至冒煙
　　故障原因①電源電壓過高；②電源電壓過低，電動機又帶額定負載運行，電流過大使繞組發(fā)熱；③修理拆除繞組時，采用熱拆法不當，燒傷鐵芯；④電動機過載或頻繁起動；⑤電動機缺相，兩相運行；⑥重繞后定于繞組浸漆不充分；⑦環(huán)境溫度高電動機表面污垢多，或通風道堵塞；
　　故障排除①降低電源電壓（如調(diào)整供電變壓器分接頭）；②提高電源電壓或換粗供電導線；③檢修鐵芯，排除故障；④減載；按規(guī)定次數(shù)控制起動；⑤恢復三相運行；⑥采用二次浸漆及真空浸漆工藝；⑦清洗電動機，改善環(huán)境溫度，采用降溫措施

某紡織廠的空調(diào)采用的是雙速電機進行調(diào)速，如果能改用變頻器進行無級調(diào)速，則可更好地進行量調(diào)節(jié)，按車間余熱量進行送風。同步電動機調(diào)速，可通過改變電源頻率和電極對數(shù)來實現(xiàn)；異步電動機調(diào)速通過改變電源頻率、電機對數(shù)和轉差率方法來實現(xiàn)。
　　變頻調(diào)速是改變供電的頻率，從而改變電動機轉速的調(diào)速方法，它基本保持了異步電動機固有的特性，即硬度高和轉速差小的特點，所以變頻調(diào)速法具有效率高、調(diào)速范圍寬、精度高和調(diào)速平滑等優(yōu)點。
　　變頻調(diào)速分電壓變頻調(diào)速、電流變頻調(diào)速和脈寬調(diào)制（PWM）型變頻調(diào)速三種類型。
　　交流電源經(jīng)二級管組成的橋式整流和電容濾波后，成為恒定的直流電壓，加之由大功率晶體管構成PWF型變頻器，使控制電路按一定規(guī)律控制PWM逆變器的各個晶體管的通和斷，從而在逆變器輸出端獲得一組等幅而不等寬的矩形脈沖波。
