Makatani Anzeru: Ma Motors a DC Amawapangitsa Kuyenda Mofatsa Ndi Mwabata

Kutsegula ndi kutseka kwa makatani anzeru amagetsi kumayendetsedwa ndi kuzungulira kwa ma micro motors. Poyambirira, ma mota a AC ankagwiritsidwa ntchito kwambiri, koma ndi kupita patsogolo kwaukadaulo, ma mota a DC apeza ntchito zambiri chifukwa cha zabwino zawo. Ndiye, ubwino wa ma motors a DC omwe amagwiritsidwa ntchito mu makatani amagetsi ndi chiyani? Kodi njira zowongolera liwiro ndi ziti?

Makatani amagetsi amagwiritsa ntchito ma motors ang'onoang'ono a DC okhala ndi zida zochepetsera magiya, omwe amapereka torque yayikulu komanso liwiro lotsika. Ma motors awa amatha kuyendetsa makatani amitundu yosiyanasiyana kutengera kuchepetsedwa kosiyanasiyana. Ma motors odziwika bwino a DC mu makatani amagetsi ndi ma motors opukutidwa ndi ma brushless motors. Ma motors a brushed DC ali ndi zabwino monga torque yoyambira, kugwira ntchito bwino, mtengo wotsika, komanso kuwongolera liwiro. Komano ma motors a Brushless DC, amadzitamandira nthawi yayitali komanso phokoso lochepa, koma amabwera ndi ndalama zambiri komanso njira zowongolera zovuta. Chifukwa chake, makatani ambiri amagetsi pamsika amagwiritsa ntchito ma motors.

Njira Zosiyanasiyana Zowongolera Magalimoto a Micro DC Motors mu Makatani Amagetsi:

1. Mukasintha liwiro la chinsalu chamagetsi cha DC motor pochepetsa mphamvu yamagetsi, magetsi okhazikika a DC amafunikira pagawo la zida. Kukaniza kwa dera la armature ndi dera losangalatsa liyenera kuchepetsedwa. Mphamvu yamagetsi ikachepa, kuthamanga kwa chinsalu chamagetsi cha DC motor kumachepetsanso.

2. Kuwongolera liwiro poyambitsa kukana kwamagulu mu gawo la zida za mota ya DC. Kukula kwa mndandanda wa kukana, kufooka kwa machitidwe amakina, komanso kuthamanga kosakhazikika. Pakuthamanga kochepa, chifukwa cha kukana kwakukulu kwa mndandanda, mphamvu zambiri zimatayika, ndipo mphamvu yotulutsa mphamvu imakhala yochepa. Kuthamanga kwa liwiro kumayendetsedwa ndi katundu, kutanthauza kuti katundu wosiyanasiyana amabweretsa zotsatira zosiyana zowongolera liwiro.

3. Kuthamanga kwamphamvu kwa maginito. Pofuna kupewa kuchulukitsitsa kwa maginito pamagetsi amagetsi a DC motor, kuyendetsa liwiro kuyenera kugwiritsa ntchito maginito ofooka m'malo mwa maginito amphamvu. Mphamvu yamagetsi yamagetsi yamagetsi ya DC imasungidwa pamtengo wake wovotera, ndipo kukana kwamtundu wamagetsi kumachepetsedwa. Powonjezera kukana kwa dera lachisangalalo la Rf, kusangalala kwapano ndi maginito kumachepetsedwa, potero kumawonjezera liwiro la mota yamagetsi yamagetsi ya DC ndikufewetsa mawonekedwe amakina. Komabe, liwiro likamakula, ngati torque yonyamula katunduyo ikadali pamtengo woyengedwa, mphamvu yagalimoto imatha kupitilira mphamvu yoyezetsa, zomwe zimapangitsa kuti mota igwire ntchito mochulukira, zomwe sizololedwa. Chifukwa chake, mukasintha liwiro ndi maginito ofooka, torque yonyamula katunduyo imatsikanso momwe liwiro la mota likukulirakulira. Iyi ndi njira yoyendetsera liwiro la mphamvu nthawi zonse. Kuti mupewe mafunde a mota kuti asaphwasulidwe ndikuwonongeka chifukwa champhamvu kwambiri ya centrifugal, ndikofunikira kuti musadutse liwiro lololedwa la mota ya DC mukamagwiritsa ntchito mphamvu yofooka ya maginito.

4. Mu dongosolo loyendetsa liwiro la galimoto yamagetsi yamagetsi DC, njira yosavuta yokwaniritsira kuwongolera liwiro ndikusintha kukana mu gawo la zida. Njirayi ndiyo yowongoka kwambiri, yotsika mtengo, komanso yothandiza pakuwongolera liwiro la makatani amagetsi.

Awa ndi mawonekedwe ndi njira zowongolera liwiro la ma motors a DC omwe amagwiritsidwa ntchito mu makatani amagetsi.
