Za a iya raba motors na fashewa cikin nau'ikan guda uku ko kuma nau'ikan kayan haɗinsu gwargwadon ka'idojin ka'idojinsu-tabbacin.
1. Nau'in hana wuta, nau'in B
Motar da baya haifar da fashewar wani abu mai fashewa na waje a yayin da fashewar ke cikin motar.Rufin motar yana da isasshen ƙarfin injin (ƙarin simintin simintin simintin gyare-gyare, farantin karfe a matsayin casing), ta yadda zai iya jure yanayin fashewa da tasirin ƙarfin waje ba tare da lalacewa ba; Ma'auni na tsari (rata da tsayi) na haɗin haɗin gwiwar wuta; bukatu don akwatunan haɗin gwiwa, na'urorin shigar waya, da sauransu; sarrafa zafin saman harsashi ta yadda ba zai iya kaiwa ga yanayin zafi mai haɗari ba.
2. Ƙara nau'in aminci, nau'in A
Hatimin motar ya fi kyau, kuma ana ɗaukar matakan kariya na IP55; zane na lantarki ya kamata yayi la'akari da rage yawan zafin jiki; lokacin da rotor ya kai yanayin zafi mai haɗari lokacin da aka kulle shi, kuma an sanye shi da na'urar lantarki mai sarrafa kansa; inganta juzu'i-zuwa-juya, ƙasa-zuwa-ƙasa da gwaje-gwajen lokaci-zuwa-lokaci na wutar lantarki mai iska; inganta amincin haɗin kai; sarrafa mafi ƙanƙantar yarda ɗaya na stator da rotor.A takaice, yana hana tartsatsin tartsatsin bazata, baka ko yanayin zafi mai haɗari daga tsarin tsari da na lantarki, don haka inganta amincin aiki.
3. Nau'in matsa lamba mai kyau, nau'in P
Motar da ke tabbatar da fashewar abin da ke cusa iska mai kyau a cikin gidaje ko kuma ya cika shi da iskar gas mara amfani (kamar nitrogen) don hana abubuwan fashewa na waje shiga motar.
Iyakar amfani:Nau'in matsewar wuta da ingantattun nau'ikan matsi sun dace da duk wuraren fashewar abubuwa masu haɗari, da injunan hana wuta (Nau'in B) ana amfani da su sosai a kasar Sin.Farashin masana'anta da farashin haɓakar motar aminci sun fi na nau'in hana wuta, kuma sun dace da Yanki kawai2 wurare.
2. Rarraba motoci a cikin iskar gas mai fashewa
1. Bisa ga rarraba wuraren fashewa
| Rarraba wuraren fashewa | yankin0 | Gundumar1 | Yanki2 |
| Mitar da kuma tsawon lokacin iskar gas mai fashewa | Wuraren da iskar gas mai fashewa ke bayyana ci gaba ko wanzu na dogon lokaci | Wuraren da iskar gas mai fashewa zai iya faruwa yayin aiki na yau da kullun | A lokacin aiki na yau da kullun, ba zai yuwu a sami mahalli mai fashewa ba, ko wurin da yake bayyana lokaci-lokaci kuma yana wanzuwa na ɗan lokaci kaɗan. |
2. Dangane da nau'in iskar gas mai fashewa

3. Alamomin tabbatar da fashewar abubuwan fashewar motoci
1. Misalai na alamomin tabbatar da fashewa don injunan asynchronous mataki uku mai hana wuta:
Motar hana wuta ta ExDI don ma'adinan kwal
ExD IIBT4 masana'anta IIBod T4 rukunin kamar: wurin tetrafluoroethylene
2. Misalai na alamomin tabbatar da fashewa don ƙarin aminci masu motsi asynchronous mataki uku:
ExE IIT3 yana dacewa da wuraren da zafin jiki na ƙonewa shine ƙungiyar T3 mai ƙonewa a cikin masana'anta.
4. Bukatun takaddun shaida guda uku don abubuwan fashewar fashewa
Lokacin da motar da ke hana fashewar ta bar masana'anta, aikin dole ne ya cika buƙatun yanayin fasaha da ka'idoji, kuma dole ne ya sami takaddun shaida guda uku da sassan da suka dace na jihar suka bayar. Dole ne farantin sunan motar ya nuna lambobin takaddun shaida guda uku, wato:
1. Takardar tabbatar da fashewa
2. Lambar lasisin samar da mota mai tabbatar da fashewa
3. Safety takardar shaida MA lambar.
Ya kamata a sami alamar EX mai ja a kusurwar dama ta sama na farantin sunan motar da kuma kan murfin akwatin fitarwa.
