Direct current (DC) ndi alternating current (AC) motors ndi mitundu iwiri yamagetsi yomwe imagwiritsidwa ntchito kwambiri. Tisanakambirane kusiyana kwa mitundu iwiriyi, choyamba tiyeni timvetse tanthauzo lake.
Galimoto ya DC ndi makina amagetsi ozungulira omwe amatha kusintha mphamvu zamagetsi kukhala mphamvu zamakina (kuzungulira). Itha kugwiritsidwanso ntchito ngati jenereta yomwe imatembenuza mphamvu zamakina (kuzungulira) kukhala mphamvu yamagetsi (DC). Moto wa DC ukakhala ndi mphamvu yakulunjika, imapanga mphamvu ya maginito mu stator yake (gawo loyima la mota). Mundawu umakopa ndikuthamangitsa maginito pa rotor (gawo lozungulira la mota). Izi zimapangitsa kuti rotor ikhale yozungulira. Kuti rotor ikhale yozungulira nthawi zonse, commutator, yomwe imakhala yozungulira magetsi imagwiritsa ntchito magetsi ku ma windings. Chiphuphu chokhazikika chozungulira chimapangidwa potembenuza kumene mafunde akulowera mumayendedwe ozungulira theka lililonse.
Ma motors a DC amatha kuwongolera liwiro lawo, zomwe ndizofunikira pamakina amakampani. Ma motors a DC amatha kuyamba nthawi yomweyo, kuyima ndikubwerera m'mbuyo. Ichi ndi chinthu chofunikira pakuwongolera magwiridwe antchito a zida zopangira. Motere,Zithunzi za XBD-4070ndi imodzi mwama injini athu otchuka a DC.
Zofanana ndi mota ya DC, chozungulira cha alternating current (AC) chimaphimba mphamvu yamagetsi kukhala mphamvu yamakina (kuzungulira). Itha kugwiritsidwanso ntchito ngati jenereta yomwe imatembenuza mphamvu yamakina (kuvota) kukhala mphamvu yamagetsi (AC).
Makamaka ma mota a AC amagawidwa m'mitundu iwiri. Motor synchronous ndi motor asynchronous. Yotsirizirayo ikhoza kukhala gawo limodzi kapena magawo atatu. Mu injini ya AC, pali mphete ya mkuwa (yopanga stator), yomwe imapangidwa kuti ipange mphamvu ya maginito yozungulira. Pamene ma windings amayendetsedwa ndi mphamvu yamagetsi ya AC, mphamvu ya maginito, imapanga pakati pawo imapangitsa kuti pakhale mpweya mu rotor (gawo lozungulira). Izi zimapanga mphamvu ya maginito, yomwe imatsutsana ndi mphamvu ya maginito kuchokera ku stator. Kulumikizana pakati pa minda iwiri kumapangitsa kuti rotor ikhale yozungulira. Mu injini ya asynchronous pali kusiyana pakati pa maulendo awiriwa. Zida zambiri zamagetsi zapakhomo zimagwiritsa ntchito ma AC motors chifukwa magetsi ochokera m'nyumba ndi alternating current (AC).
Kusiyana pakati pa DC ndi AC mota:
● Magetsi ndi osiyana. Ngakhale ma motors a DC amayendetsedwa ndi magetsi, ma AC motors amayendetsedwa ndi ma alternating current.
● Muma injini a AC, chombocho chimakhala choyima pomwe mphamvu ya maginito imazungulira. Mu ma motors a DC zida zimazungulira koma maginito amangokhala osasunthika.
● Ma motors a DC amatha kukwaniritsa malamulo osalala komanso achuma popanda zida zowonjezera. Kuwongolera liwiro kumatheka powonjezera kapena kuchepetsa mphamvu yamagetsi. Ma mota a AC amabwerezanso kugwiritsa ntchito zida zosinthira pafupipafupi kuti asinthe liwiro.
Ubwino wa ma mota a AC ndi awa:
● Kuchepetsa mphamvu zamagetsi zoyambira
● Kuwongolera bwino pamiyezo yamakono ndi mathamangitsidwe
● Kusinthasintha kokulirapo pazofunikira zosiyanasiyana zosinthira ndikusintha liwiro ndi ma torque
● Kukhalitsa bwino ndi moyo wautali
Ubwino wa ma mota a DC ndi awa:
● Kuyika ndi kukonza zinthu zosavuta
● Mphamvu yoyambira kwambiri ndi torque
● Kuyankha mwachangu poyambira/kuyimitsa ndi kuthamangitsa
● Kusiyanasiyana kwamitundu yosiyanasiyana yamagetsi
Mwachitsanzo, ngati muli ndi fani yamagetsi yapanyumba, imagwiritsa ntchito mota ya AC chifukwa imalumikizana mwachindunji ndi gwero lamagetsi la AC la nyumba yanu, zomwe zimapangitsa kuti ikhale yosavuta kugwiritsa ntchito komanso yocheperako. Magalimoto amagetsi, kumbali ina, amatha kugwiritsa ntchito ma motors a DC chifukwa amafunikira kuwongolera bwino kwa liwiro la mota ndi torque kuti apereke luso loyendetsa bwino komanso kuthamanga kwabwino.
