Misalai da Take-Off na Tsohon Zabi?

Takaita da Take-Off na Tsohon Zabi

Take-Off na tsohon zabi shi ne wani abincin da ke taimaka waɗanda suke da kuma yin daɗi ga motoci na DC ta hanyar gudanar da wurin mai karkashin karshe.

An haɗa shi ne sabon takaita na motoci:

Amsa E=Voltage na Gidaje; Eb=Back EMF; Ia=Armature Current; and Ra=Armature Resistance. Daga baya ba a yi Eb = 0, don haka E = Ia.Ra.

Diagram na Take-Off

Abubuwa kamar OFF, RUN da kuma fuskantar abubuwa suna nuna a cikin diagram na take-off, wadannan sun bayyana sautin da ma'adin abinci.

Ban sha'awa na Take-Off na Tsohon Zabi

A nan ban sha'awar, take-off shine mutanen ruwaitoci, an samun shi a cikin gabatarwar abubuwa, kamar yadda ake nuna a figure. Fuskantar abubuwan da suka nuna a cikin wannan suna nufin studs, kuma suna nuna a cikin OFF, 1, 2, 3, 4, 5, da kuma RUN. Wannan da yaɗa, akwai uku masu muhimmiyar fuskantar:

"L" wire terminal (connected to the positive terminal of the power supply)

"A" armature terminal (connected to armature winding)

"F" excitation terminal (connected to excitation winding)

Prinsipin Yakin

Bayan a duba ban sha'awar, za a iya duba aiki na take-off na tsohon zabi. Kafin a sake rarrabe motoci na DC, handle ita ce a matsayin OFF. Handle ya yi karfi ta hanyar karamin karamin kungiyoyi, kuma ya fara zuwa stud na 1. A cikin halin, field winding na motoci na shunt ko compound ya samu gidaje ta hanyar non-voltage coil a kan hanyar da aka bayar da resistance na take-off. Duk take-off resistance ya samu shiga a cikin armature a kan series. Don haka, current na karkashin armature ya zama mai karkasha saboda equation na current a wannan lokacin ya zama:

Idan handle ya yi karfi, ya fara zuwa studs 2, 3, 4, etc., kuma ya fara cutta resistance na series a cikin circuit na armature idan speed na motoci ya zama. A lokacin da handle ya ci "RUN", duk take-off resistance ya ci, kuma motoci ya yi aiki a cikin speed na tsakanin.

Wannan shine saboda back electromotive force ya fara samu a cikin speed don iya cutta voltage na gidaje da kuma rage armature current.

Mechanism na Amnata

Coil na voltage-free ya taimaka cewa take-off yake da aiki a matsayin "RUN" a lokacin da yawa, kuma ya rage ita zuwa "OFF" idan an rage gidaje, wanda ya taimaka amnata.

Matsayin Da Take-Off na Tsohon Zabi Da Take-Off na Nairuwa Zabi

Duk da cewa take-off na tsohon zabi, take-off na nairuwa zabi suna iya dalilce da range masu kyau na speed na motoci ba wasu take-off ba, wanda ya taimaka musamman a wasu ayyuka.

Kasuwanci na Take-Off na Tsohon Zabi

Wani babban kasuwanci na take-off na tsohon zabi shine performance irin, motoci na buƙatun speed, wanda ake daidaita ta hanyar field rheostat. Idan a zama speed na motoci ta hanyar field resistance mai karkasha, zai iya rage current na field na shunt.
