DC galimoto: chipangizo, ntchito ntchito

The ntchito m'nkhani ino, unit zikudalira pa chodabwitsa cha kupatsidwa ulemu mu atomu. Izi ndi zofunika mfundo za ntchito ya galimoto DC. Izo ziri zodziwika bwino kuti panopa kumangopitirizabe wochititsa anakafika adalira anaikidwa zone maginito, ali zimakhudzanso mphamvu, kumene anatsimikiza mogwirizana ndi ulamuliro Kumanzere: F = B Ine L, kumene -electric panopa Ine, B - munda kupatsidwa ulemu; L - imaŵerengedwa kutalika. Kufika mizere mphamvu ya maginito, kondakitala amapeza mphamvu electromotive, amene poyerekezera otaya panopa ukuperekedwa, ndipo akutchedwa n'zosiyana kapena kauntala. galimoto za otembenuka DC mphamvu mu mawonekedwe mawotchi mphamvu, komanso pang'ono munagulira magetsi.

Pamwamba pa chipangizo makina msonkhano Tingaone motere: injini DC kapangidwe ndi osavuta, izo ukufanizidwa ndi inductor ndi armature, amene amakhala ndi kusiyana mpweya.

Inductor amalenga n'kupuma maginito za makina, ndipo nawonso, imakhala chimango, mzati (waukulu ndi zina). Wokwera pa mitengo chimango ndi gawo lapansi lokha kumafuna mu unsembe wa dera maginito. Waukulu munda kumulowetsa mizati akupanga kupanga maginito, ndi owonjezera - koyilo kusintha kugwirizana.

Njinga DC okonzeka ndi nangula kwa mapepala osiyana, waya ndi koyilo mosungiramo (zokuzira pa kutsinde yamphamvu wa zitsulo zamkuwa). Zofunika kuchotsa ikuchitika ntchito burashi panopa. Iwo atathana ndi unachitikira mu malo ena, amene amatipatsa mphamvu zinafunika mwa mavuto padziko wokhometsa.

Pa ntchito ya DC burashi galimoto chimachititsanso pamwamba pa kufalitsidwa mosungiramo mu njira yakuti iwo mowirikiza amayenda mbale wina ndi mzake. Choncho kusinthana Ndime yomweyi ya koyilo ndi armature panopa zikusintha. Ndondomeko komanso zochitika akhudzana ndi, amatchedwa kusinthitsa. EMF amachititsa panopa zina, amene ali kugawa ndi m'goli mphamvu kachulukidwe padziko maburashi lapansi. Kuti ndi chifukwa chachikulu sparking wokhometsa (mu mphamvu ya zodabwitsazi Akuti kusinthitsa ndi khalidwe kuwunikira kumatanthauza mphamvu yake).

DC galimoto angathe malemeredwe likufa - kulenga mwa izo ndi maginito chofunika chipangizo. Iwo agawidwa m'magulu anayi (galimoto njira):

• Independent amene kumulowetsa ali zoyendetsedwa kuchokera kunja DC gwero.
• Yomweyi - kumulowetsa mu kufanana kupereka armature koyilo.
• Amacita - chikugwirizana mu mndandanda.
• Wothira (ndi siriyo ndi kufanana coils malemeredwe).

Poyamba poyambira voteji ndi armature chili ali ziro. Kulimbana ndi ang'ono, panopa kuyambira akhoza kukhala nthawi 10-20 kuposa oveteredwa. Kuonetsetsa yosalala chiyambi-mmwamba umagwiritsidwa resistor stepwise amene kukana mtengo wothekera zosankhidwa sitata galimoto panopa.
