Menene hanyoyin da za a rage lokacin farawa na motar?

1. Farawa kai tsaye

Farawa kai tsaye shine tsarin haɗa kai tsayestatoriskar waniinjin lantarkizuwa wutar lantarki da farawa a ƙimar ƙarfin lantarki. Yana da halaye na babban ƙarfin farawa da gajeren lokacin farawa, kuma shine mafi sauƙi, mafi tattalin arziki, kuma mafi aminci hanyar farawa. Lokacin farawa a cikakken ƙarfin lantarki, halin yanzu yana da girma kuma ƙarfin farawa ba shi da girma, yana sa sauƙin aiki da sauri don farawa. Koyaya, wannan hanyar farawa tana da manyan buƙatu don ƙarfin grid da kaya, kuma galibi ya dace da farawa injin ƙasa 1W.

2.Juriya jerin motoci farawa

Fara juriya jerin motoci hanya ce ta rage ƙarfin farawa. A yayin aiwatar da farawa, ana haɗa resistor a jere a cikin da'irar iskar gas ta stator. Lokacin da motsin farawa ya wuce, ana haifar da raguwar ƙarfin lantarki akan resistor, yana rage ƙarfin lantarki da ake amfani da shistatoriska. Wannan zai iya cimma burin rage lokacin farawa.

3.Farawar transformer da kai coupling

Yin amfani da raguwar ƙarfin wutar lantarki da yawa na autotransformer ba zai iya saduwa da buƙatun farawa daban-daban ba, har ma ya sami babban karfin farawa. Hanyar farawa ce ta rage yawan wutar lantarki da aka saba amfani da ita don fara manyan injunan iya aiki. Babban amfaninsa shine cewa karfin farawa yana da girma. Lokacin da iska ta kasance a 80%, karfin farawa zai iya kaiwa 64% na karfin farawa kai tsaye, kuma za'a iya daidaita karfin farawa ta hanyar famfo. Aiki na hukuma “Littafin Injiniyan Injiniya”, gidan mai injin injiniya!

4.Star Delta Decompression Fara

Don motar squirrel cage asynchronous motor tare da aiki na yau da kullunstatorwinding da aka haɗa ta hanyar triangular, idan an haɗa iskar stator a cikin siffar tauraro yayin farawa sannan kuma a haɗa shi cikin siffar triangle bayan farawa, zai iya rage lokacin farawa kuma ya rage tasirinsa akan grid na wutar lantarki. Ana kiran wannan hanyar farawa star delta decompression farawa, ko kuma farawa tauraro delta kawai (y&farawa).

Lokacin amfani da hanyar farawa ta star delta, lokacin farawa shine kashi ɗaya bisa uku na ainihin hanyar farawa kai tsaye ta amfani da hanyar haɗin alwatika. A star delta farawa, lokacin farawa shine sau 2-2.3 kawai. Wannan yana nufin cewa lokacin amfani da tauraro delta farawa, farawa kuma yana raguwa zuwa kashi ɗaya bisa uku na abin da yake lokacin farawa kai tsaye ta amfani da hanyar haɗin triangle.

Ya dace da yanayin da babu kaya ko nauyi farawa. Kuma idan aka kwatanta da duk wani injin farawa, tsarinsa shine mafi sauƙi kuma farashi kuma shine mafi arha.

Bugu da ƙari, hanyar farawa ta star delta shima yana da fa'ida, wanda shine lokacin da kaya yayi haske, zai iya ba da damar injin yayi aiki a ƙarƙashin hanyar haɗin tauraron. A wannan lokaci, za a iya daidaita ma'auni da nauyin nauyi, wanda zai iya inganta ingancin motar da kuma adana wutar lantarki.

5.Frequency Converter farawa (mai laushi farawa)

 Mai jujjuya mitar ita ce mafi haɓakar fasaha, cikakken aiki, kuma ingantaccen na'urar sarrafa motar a fagen sarrafa injin na zamani. Yana daidaita gudu da jujjuyawar motar ta hanyar canza mitar wutar lantarki. Saboda shigar da fasahar lantarki da fasahar microcomputer, farashin yana da yawa kuma abubuwan da ake buƙata don masu fasaha suma suna da yawa. Don haka, ana amfani da shi musamman a cikin filayen da ke buƙatar tsarin saurin gudu da buƙatun sarrafa saurin gudu.
