Maginito mkuzamawu - Mfundo ntchito ndi ntchito

Maginito mkuzamawu - ichi ndi malo amodzi magetsi zida, limene lakonzedwa kulamulira mtengo wa ukulu wa alternating panopa kudzera zonse ndi. Mfundo zikugwira ntchito chipangizo izi zachokera makhalidwe sanali liniya ya maginito dera maginito. A mkuzamawu maginito kawirikawiri amagwiritsidwa ntchito m'munda wa ulamuliro basi wa injini magetsi (onse synchronous ndi asynchronous) kuti ntchito pa alternating panopa.

chipangizo A pogwiritsa ndi wosavuta. Maginito mkuzamawu imakhala ya opaleshoni kumulowetsa, amene ali pa ndodo yake kwambiri. Linapangidwa awiri mndandanda-olumikizidwa coils. Control kumulowetsa ndi ambiri ankasinthana ili pa ndodo pakati. Ngati palibe panopa umaperekedwa, ndi kudutsa ntchito kumulowetsa, amene chikugwirizana pa mndandanda ndi katundu, dera maginito sati zimalimbikitsa nimuponye AC voteji chifukwa ochepa motsatana. Mu nkhani iyi, voteji onse adzafooka pa kukana koyilo ikugwira ntchito (mu nkhani iyi kudzakhala zotakasika). Pankhaniyi, katundu adzakhala allocated mphamvu otsika.

The chipangizo maginito monga mkuzamawu maginito ladzala chifukwa panopa umadutsa ulamuliro kumulowetsa. Chifukwa cha kuchuluka kwa madzulowo ndi okwanira ngakhale panopa yaing'ono. Chifukwa cha ndondomeko iyi zotakasika chigawo chimodzi cha ntchito kumulowetsa kukana adzakhala ndichepe kwambiri ndi mtengo ziliri pa dera ulamuliro mofulumira kuonjezera. Choncho, ntchito mbendera ochepa ulamuliro wa kumulowetsa akhoza lizilamuliridwa ndi mphamvu zambiri.

Pankhani losavuta ngati chipangizo ngati mkuzamawu maginito umaimira inductance amene opareshoni ndi panopa mwachindunji. Pakuti ziwalo ulamuliro inductance kuti chikugwirizana pa mndandanda kwa AC katundu dera.

Pakuti mfundo yaikulu ya inductor ziliri pa mndandanda dera ndi katundu yaing'ono. Pa otsika inductance panopa adzakhala lalikulu mu unyolo Daisy. Pa potsegula, motero, mtengo adzakhala kuwonjezera yolingana ndi kuchepa inductance. Pali mamangidwe zambiri zofotokoza mmene chipangizo choterocho, monga mphamvu ya maginito ntchito monga Mwachitsanzo, si kukhudzana kulandirana (kwa contactless kusintha panopa) kwa anawaonjezera kuwirikiza kawiri mtengo pafupipafupi, ziziyenda ndi voteji mu dera la modulating pafupipafupi mkulu chidzasonyeza otsika chizindikiro pafupipafupi, monga chipangizo choterocho monga mkuzamawu zatsopano kulamulira voteji ndi zina zotero.

Ngakhale zaposachedwapa, amplifiers maginito anali m'madera ena anakankhira mmbuyo kugwiritsa ntchito zipangizo michenga yopangira zida zamagetsi, m'madera monga kasamalidwe abulusa magetsi mu makina zomangamanga, kuwala lamulo maholo zoimbaimba ndipo cinemas, pa kayendetsedwe ka sitima maginito mkuzamawu alibe mpikisano lero.
