Synchronous motor - abũbuwan amfãni, kuma disadvantages

A mafi yadu amfani da irin wannan na'ura a matsayin synchronous mota da aka samu a wani masana'antu inda akwai lantarki Gudun a m gudun. Alal misali, compressors da iko injuna, farashinsa actuators. Har ila yau, wani synchronous mota ne wani ɓangare, kuma da yawa iyali kayan, kamar shi ne a cikin sa'o'i.

A qa'ida ta aiki da wannan na'ura ne quite sauki. The hulda da juyawa Magnetic filin na armature samar da alternating halin yanzu kuma da halin maganaɗisu filayen a kan inductor sandunan generated m halin yanzu shi ne tushen da manufa na aiki da irin wannan na'urar a matsayin synchronous lantarki motor. Yawanci, an inductor located a kan na'ura mai juyi, da kuma anga - da stator. Iko injuna kamar sandunan amfani electromagnets. Amma akwai wani irin low-ikon - wani synchronous mota tare da m maganadiso. Babban bambancin dake tsakanin synchronous da asynchronous inji - stator da kuma na'ura mai juyi zane.

Don hanzarta da mota har zuwa rated gudun matakin sau da yawa amfani asynchronous yanayin. A wannan yanayin, da inductor Tuddan short-circuited. Bayan da engine ke da rated gudun, da rectifier SUPPLiES DC inductor. Kawai maras gudun synchronous motor iya aiki da kansa.

Irin wannan mota yana da yawa abũbuwan amfãni. Shi ne wani tsari na girma fiye da hadaddun asynchronous na'ura, amma wannan ne biya diyya a yawan abũbuwan amfãni. Daya daga cikin manyan abũbuwan amfãni - da ikon aiki ba tare da amfani da amsawa ikon ko tasiri. Kamar wancan ne da engine ikon factor ne daidai da hadin kai. A karkashin wadannan yanayi, wani synchronous AC mota ne na musamman aiki kaya cibiyar sadarwa bangaren. A gefe sakamako ne don rage motor size (ga wani shigar da mota, da stator Tuddan da aka lasafta da aiki da mai amsawa igiyoyin a). Duk da haka, da synchronous motor iya samar da real kuma amsawa ikon, da ke aiki a overexcitation yanayin.

A synchronous mota ne da yawa kasa kula da hawa da sauka, da irin ƙarfin lantarki saukad a cikin cibiyar sadarwa. Kamar wutar lantarki da motoci da hakan jure overloads. zai yiwu mu ƙara obalodi iyawa daga cikin engine ta kara zumudi halin yanzu. A amfani da synchronous inji shi ne ma m maras muhimmanci rotational gudun a wani kaya (sai obalodi).

Lalle, wannan wata na'ura a matsayin synchronous mota yana da kasawarmu. Su suna hade da high halin kaka da kuma rikitarwa aiki. Babban matsalar ne zumudi na mota da kuma bullo da cikin synchronism. A halin yanzu samu yaduwar thyristor exciters, wanda da yawa mafi girma yadda ya dace, fiye da na lantarki pathogens. Duk da haka, su kudin ne yafi hakan. Amfani da thyristor canza iya warware matsaloli da yawa: mafi kyau duka zumudi halin yanzu tsari, tallafawa cosine phi m darajar, da iko irin ƙarfin lantarki a kan hula, sarrafa da stator igiyoyin da kuma na'ura mai juyi a cikin gaggawa yanayin, da kuma a yanayin saukan obalodi.
