Zosintha zamakono za 2200W chain saw

Ac-dc power supply principle of electric chainsaw

Choyamba, mfundo ntchito ya unyolo magetsi anawona

Chainsaw yamagetsi ndi mtundu wa chida champhamvu chomwe chimadula poyendetsa tsamba la macheka, lomwe nthawi zambiri limagwiritsidwa ntchito podula zinthu monga matabwa, zitsulo ndi pulasitiki. Mfundo yake yogwirira ntchito ndikuyendetsa rotor ya injini kuti izungulire posinthana ndi theka la milungu yabwino komanso yoyipa yamagetsi, ndikuyendetsa tsamba la macheka kuti lidulidwe. Mu makina amtundu wamagetsi, mphamvu ya AC imagwiritsidwa ntchito nthawi zambiri. Komabe, m'zaka zaposachedwa, ndikukula kosalekeza kwaukadaulo wamagetsi a DC, ma soya amagetsi ochulukirachulukira amagwiritsanso ntchito mphamvu ya DC.

Chachiwiri, kusiyana pakati pa mphamvu ya AC ndi mphamvu ya DC

Kusiyana kwakukulu pakati pa mphamvu ya AC ndi mphamvu ya DC ndikuwongolera komwe kuli pano. Mphamvu yamagetsi ya AC imasintha nthawi ndi nthawi, pomwe magetsi a DC amayenda mbali imodzi. Kuphatikiza apo, mitundu iwiri yosiyanasiyana yamagetsi imasiyananso ndi mawonekedwe amagetsi ndi mphamvu. Magetsi a Ac nthawi zambiri amakhala ndi voteji komanso mphamvu zambiri, ndipo amatha kugwira ntchito kwa nthawi yayitali. Mphamvu zamagetsi za DC nthawi zambiri zimakhala ndi magetsi otsika ndi mphamvu, komanso moyo wamfupi wautumiki.

Chachitatu, mfundo yamagetsi yamagetsi imatha kukhala magetsi a AC ndi DC

Mu makina amtundu wa AC, chosinthira magetsi chimasintha voteji yamagetsi a AC kumagetsi ogwiritsira ntchito omwe amafunidwa ndi makina amagetsi amagetsi, kenako ndikukonzanso dera lowongolera kuti lisinthe AC kukhala yachindunji. Mu makina amagetsi amagetsi okhala ndi magetsi a DC, chosinthira magetsi chimawongolera mwachindunji voteji ya AC kupita kumagetsi ofunikira a DC osafunikira kusinthidwa kudzera pagawo lokonzanso.

Kuphatikiza apo, injini yamagetsi yamagetsi yamagetsi iyeneranso kusinthira kumitundu yosiyanasiyana yamagetsi. Mukamagwiritsa ntchito mphamvu ya AC, galimotoyo imafunika kukhala ndi inductance yokwanira komanso mphamvu kuti igwirizane ndi liwiro ndi mphamvu ya rotor. Mukamagwiritsa ntchito mphamvu ya DC, galimotoyo imayenera kukhala ndi mawonekedwe abwino amagetsi ndi ukadaulo wowongolera dera kuti ipereke kusewera kwathunthu pazabwino za mphamvu ya DC.

Chachinayi, magwiridwe antchito a unyolo wamagetsi adawona pansi pazikhalidwe zosiyanasiyana

Kuchita kwa makina opangira magetsi pansi pazigawo zosiyanasiyana kumakhudzidwa ndi mtundu wa magetsi ndi makhalidwe a galimoto. Pansi pa mphamvu zomwezo ndi ma voliyumu, magetsi a AC nthawi zambiri amatha kupereka mphamvu zoyambira ndi torque, koma kutulutsa kusokoneza kwakukulu kwamagetsi. Mphamvu yamagetsi ya DC imakhala ndi magwiridwe antchito abwino komanso olondola, koma zofunikira zamagalimoto ndizokwera komanso mtengo wake ndi wapamwamba.

Mwachidule, mfundo yoti makina opangira magetsi amatha kukhala ndi magetsi a AC ndi DC ali pakusintha kwa thiransifoma yamagetsi komanso kusinthasintha kwa mota. Pansi pazigawo zosiyanasiyana zadera, mawonekedwe a chainsaw yamagetsi amasiyananso. Choncho, posankha makina opangira magetsi, m'pofunika kuganizira zofunikira zodulira ndi malo ogwira ntchito kuti musankhe mtundu woyenera wa magetsi ndi mtundu wa galimoto.
