Lokacin da motar ke canza wutar lantarki zuwa makamashin injina, shi ma ya rasa wani bangare na makamashin da kansa.Gabaɗaya, asarar motar na iya kasu kashi uku: asara mai canzawa, ƙayyadaddun asara da asara ta ɓace.

1. Haɓaka masu canzawa sun bambanta da kaya, ciki har da asarar juriya na stator (asarar tagulla), asarar juriya na rotor da asarar juriya.

2. Kafaffen asarar yana da zaman kanta daga kaya, ciki har da hasara mai mahimmanci da asarar inji.Asarar baƙin ƙarfe ta ƙunshi asarar hysteresis da asarar halin yanzu, wanda ya yi daidai da murabba'in ƙarfin lantarki, kuma asarar hysteresis shima ya yi daidai da mitar.

3. Sauran hasarar da suka ɓace sune asarar injiniyoyi da sauran asara, gami da asarar gogayya na bearings da asarar juriyar iska ta hanyar jujjuyawar fanko da rotors.

Rarraba Asarar Mota

Matakan da yawa don Rage Asarar Mota

1 hasara na stator

Babban hanyoyin da za a rage asarar I^2R na stator motor sune:

1. Ƙara giciye-sashe yanki na stator Ramin.A ƙarƙashin diamita na waje guda ɗaya na stator, haɓaka yanki na yanki na stator Ramin zai rage yankin da'irar maganadisu kuma yana haɓaka haɓakar haƙora.

2. Ƙara cikakken Ramin Ramin Ramin stator, wanda shine mafi kyau ga ƙananan ƙananan ƙananan motoci.Aiwatar da mafi kyawun juyi da girman rufi da babban yanki na giciye na waya na iya ƙara cikakkiyar rabo na stator.

3. Yi ƙoƙarin rage tsayin ƙarshen juyawa na stator.Asarar ƙarshen iskar iskar iskar gas tana lissafin 1/4 zuwa 1/2 na jimlar asarar iska.Rage tsayin ƙarshen juyawa zai iya inganta ingantaccen injin.Gwaje-gwaje sun nuna cewa ƙarshen ƙarshen yana raguwa da 20% kuma an rage asarar da 10%.

2 Asarar rotor

Asarar I^ 2R na injin rotor yana da alaƙa da juriya na yanzu da juriya.Madaidaitan hanyoyin ceton makamashi sune kamar haka:

1. Rage rotor halin yanzu, wanda za'a iya la'akari da shi dangane da haɓaka ƙarfin lantarki da ƙarfin wutar lantarki.

2. Ƙara giciye-sashe yanki na rotor Ramin.

3. Rage juriya na jujjuyawar iska, kamar yin amfani da wayoyi masu kauri da kayan da ke da ƙarancin juriya, wanda ya fi ma'ana ga ƙananan motoci, saboda ƙananan injina galibi ana jefa rotors na aluminum, idan an yi amfani da rotors na jan ƙarfe, jimillar asarar na'urar. Mota za a iya rage da 10% ~ 15%, amma yau simintin jan karfe rotor na bukatar high masana'antu zafin jiki da kuma fasahar ba har yanzu shahararsa, da kuma farashin ne 15% zuwa 20% sama da na simintin aluminum rotor.

3 Core hasara

Ana iya rage asarar baƙin ƙarfe na motar ta hanyoyi masu zuwa:

1. Rage maɗaukakiyar maganadisu kuma ƙara tsawon ɗigon ƙarfe don rage yawan ƙarfin maganadisu, amma adadin baƙin ƙarfe da ake amfani da shi a cikin motar yana ƙaruwa daidai da haka.

2. Rage kauri na takardar ƙarfe don rage asarar da aka jawo.Misali, maye gurbin takardan karfen siliki mai zafi mai birgima tare da takardar siliki mai sanyi-birgima na iya rage kauri na takardar karfen siliki, amma takardar ƙarfe na bakin ciki zai ƙara yawan zanen ƙarfe da kuma farashin masana'anta.

3. Yi amfani da takardar karfen siliki mai sanyi-birgima tare da kyawawa mai kyau na maganadisu don rage asarar hysteresis.

4. Dauki babban aikin ƙarfe guntu rufin rufin ƙarfe.

5. Maganin zafi da fasaha na masana'antu, ragowar danniya bayan sarrafa ƙarfin ƙarfe zai yi tasiri sosai ga asarar motar.Lokacin sarrafa takardar siliki na karfe, jagorar yankewa da damuwa mai ƙarfi suna da tasiri mafi girma akan ainihin asarar.Yanke tare da birgima na siliki karfe takardar da zafin magani na silica karfe takardar naushi na iya rage asarar da 10% zuwa 20%.

4 Asara bata

A yau, fahimtar hasarar ɓataccen mota har yanzu yana cikin matakin bincike.Wasu daga cikin manyan hanyoyin da za a bi don rage asarar da ba ta dace ba a yau sune:

1. Yi amfani da magani mai zafi da ƙarewa don rage gajeriyar kewayawa a saman rotor.

2. Jiyya na rufewa a kan saman ciki na ramin rotor.

3. Rage masu jituwa ta hanyar haɓaka ƙirar iska ta stator.

4. Haɓaka ƙira na daidaituwar ramin rotor da rage jituwa, haɓaka stator da rotor cogging, ƙirƙira siffar ramin rotor azaman ramummuka masu karkata, da yin amfani da iska mai haɗaɗɗun sinusoidal, tarwatsewar iska da iska mai nisa don rage girman jituwa mai girma. ;Yin amfani da laka na maganadisu ko maganadisun ramin maganadisu don maye gurbin shingen ramin insulating na gargajiya da kuma cika ramin madaidaicin ƙarfe na ƙarfe tare da laka Ramin maganadisu hanya ce mai inganci don rage ƙarin asara.

5 asarar gogayya ta iska

Asarar gogayya ta iskar tana da kusan kashi 25% na yawan asarar motar, wanda yakamata a ba da kulawar da ta dace.Asarar gogayya yawanci ana haifar da ita ta hanyar bearings da hatimi, waɗanda za a iya rage su ta matakan masu zuwa:

1. Rage girman girman shaft, amma saduwa da buƙatun ƙarfin fitarwa da ƙarfin rotor.

2. Yi amfani da bege masu inganci.

3. Yi amfani da ingantaccen tsarin lubrication da mai mai.

4. Karɓi fasahar rufewa na ci gaba.
