Me yasa Motar AC Asynchronous ke mamaye Gudanar da Motsi na Masana'antu?

A cikin ma'aikatu da wurare marasa ƙima, ingantaccen juzu'in wutar lantarki zuwa jujjuyawar inji ana samun su ta hanyarMotar Asynchronous AC(wanda kuma aka sani da induction motor). Ba kamar injunan aiki tare da ke juyawa daidai a mitar wadata ba, ƙirar asynchronous tana gabatar da "zamewa" mai sarrafawa tsakanin na'ura mai juyi da filin maganadisu mai jujjuyawa na stator. Wannan zamewar yana ba da damar kariyar kitse na asali, gini mai sauƙi, da ƙaramar kulawa - yana mai da shi zaɓi na asali don ƙayyadaddun sauri da aikace-aikacen juzu'i.

1️⃣ Ƙa'idar aiki da Slip Phenomenon

TheMotar Asynchronous ACyana aiki akan dokar Faraday ta shigar da wutar lantarki. Lokacin da aka yi amfani da wutar lantarki mai kashi uku (ko lokaci-ɗaya) AC zuwa iskar iskar gas, ana ƙirƙirar filin maganadisu mai juyawa. Wannan filin yana yanke masu rotor, yana haifar da halin yanzu a cikinsu. Ƙwararrun da aka jawo sannan yana hulɗa tare da filin stator don samar da juzu'i. Koyaya, na'ura mai juyi ba zai iya kaiwa ga saurin daidaitawa daidai ba; dole ne ya "zame" a baya. Ana bayyana zamewa azaman bambancin kashi tsakanin saurin aiki tare da ainihin saurin rotor.

Wannan zamewar dabi'a tana ba da fasali mai mahimmanci: sarrafa kai. Lokacin da nauyin injin ya ƙaru, mai jujjuya yana raguwa kaɗan, zamewa yana ƙaruwa, ƙarin halin yanzu ana jawo shi, kuma karfin juyi yana tashi kai tsaye har sai an kai ga daidaito. Haka kuma, daMotar Asynchronous ACbaya buƙatar maganadisu na dindindin ko zoben zamewa (a cikin nau'in squirrel-cage), yana mai da shi karko kuma mai tsada. Wannan shine dalilin da ya sa induction Motors ke lissafin sama da kashi 90% na ikon masana'antu a duniya.

2️⃣ Halayen Saurin Karfi & Hanyoyin Farkowa

3️⃣ Azuzuwan Ingantacciyar (IE1 zuwa IE5) da Taimakon Makamashi

Ingantacciyar mota tana tasiri kai tsaye farashin aiki. Standarda'idar Internationalasashen Duniya IEC 60034-30-1 yana bayyana azuzuwan inganci don ƙarancin wutar lantarkiMotar Asynchronous AC. Haɓakawa daga IE1 zuwa IE3 ko IE4 na iya rage yawan amfani da makamashi na shekara ta 20-40%.

Lokacin siyan waniMotar Asynchronous AC, Koyaushe tabbatar da ingancin farantin suna kuma la'akari da jimlar farashin sake zagayowar rayuwa (sayan + wutar lantarki sama da shekaru 10-15). Haɓaka inganci na 2% akan injin 100 kW yana gudana awanni 6000 / shekara yana adana sama da 10,000 kWh kowace shekara.

4️⃣ Insulation, Rufewa, da hanyoyin sanyaya
