Tsopano izoEPUndiEMAamagwiritsidwa ntchito mochulukirachulukira, monga akatswiri pantchito yama hydraulic, ndikofunikira kuti mukhale ndi chidziwitso choyambirira cha ma mota.

Tiyeni tikambirane mwachidule za chiyambi cha injini servo lero.

1Kodi mphamvu yoyambira ya injini ndi yayikulu kapena yaying'ono kuposa momwe imagwirira ntchito nthawi zonse?Chifukwa chiyani?

2Chifukwa chiyani injini imakakamira komanso yosavuta kuyimitsa?

Mafunso awiriwa ndi amodzi.Mosasamala kanthu za katundu wa dongosolo, chizindikiro chopotoka ndi zifukwa zina, chiyambi cha injini ndi chachikulu kwambiri,

Tiyeni tikambirane mwachidule za vuto loyambira panopa kuchokera ku injini yokha (osaganizira za vuto la chiyambi chofewa).

Rotor ya mota (motor DC) imapangidwa ndi ma coil, ndipo mawaya agalimoto amadula mizere yolumikizira maginito panthawi yogwira ntchito kuti apange mphamvu yamagetsi.

Panthawi yomwe injiniyo imapatsidwa mphamvu, chifukwa mphamvu ya electromotive yomwe inachititsa kuti isapangidwe, malinga ndi lamulo la Ohm, poyambira panopa ndi:

IQ=E0/R

KutiE0ndi koyilo kuthekera ndiRndi kukana kofanana.

Pa ntchito ya galimoto, poganiza kuti anachititsa electromotive mphamvu ndiE1, kuthekera uku kumalepheretsa kuzungulira kwa injini, kotero kumakhalanso mphamvu yamagetsi yamagetsi, malinga ndi lamulo la Ohm:

I=(E0-E1)/R

Popeza kuthekera kofanana kudutsa koyilo kumachepetsedwa, zomwe zikugwira ntchito zimachepetsedwa.

Malingana ndi muyeso weniweni, mphamvu ya injini yamagetsi pamene ikuyamba ndi pafupifupi 4-7nthawi ya ntchito yachibadwa, koma nthawi yoyambira ndi yochepa kwambiri.Kupyolera mu inverter kapena chiyambi china chofewa, mphamvu yanthawi yomweyo idzagwa.

Kupyolera mu kusanthula pamwambapa, ziyenera kukhala zosavuta kumvetsetsa chifukwa chake galimotoyo imakhala yosavuta kuwotcha pambuyo pokakamira?

Galimoto ikasiya kuzungulira chifukwa cha kulephera kwa makina kapena kulemedwa kwambiri, waya sudzadulanso mzere wolowetsa maginito, ndipo sipadzakhalanso mphamvu yamagetsi yamagetsi.Panthawiyi, kuthekera kwa malekezero onse a koyilo nthawi zonse kumakhala kwakukulu kwambiri, ndipo panopa pa koyiloyo ndi pafupifupi wofanana Ngati njira yoyambira ndi yaitali kwambiri, idzatentha kwambiri ndikuwononga galimoto.

Ndikosavuta kumvetsetsa pankhani yosunga mphamvu.

Kuzungulira kwa koyilo kumayambitsidwa ndi mphamvu ya Ampere pa iyo.Mphamvu ya Ampere ikufanana ndi:

F=BIL

Nthawi yomwe injini imayamba, yapano ndi yayikulu kwambiri, mphamvu ya ampere imakhalanso yayikulu kwambiri panthawiyi, ndipo torque yoyambira ya koyilo imakhalanso yayikulu kwambiri.Ngati panopa nthawi zonse ndi yaikulu kwambiri, ndiye kuti mphamvu ya ampere nthawi zonse imakhala yaikulu kwambiri, momwemonso galimoto imazungulira mofulumira kwambiri, kapena mofulumira komanso mofulumira.Izi sizomveka.Ndipo panthawiyi, kutentha kudzakhala kwamphamvu kwambiri, ndipo mphamvu zonse zidzagwiritsidwa ntchito potentha, ndiye bwanji muzigwiritsa ntchito kukankhira katundu kuti agwire ntchito?

Pogwira ntchito moyenera, chifukwa cha kukhalapo kwa mphamvu yamagetsi yamagetsi, zamakono zidzakhala zochepa kwambiri panthawiyi, ndipo kutentha kudzakhala kochepa kwambiri.Mphamvu zomwe zimaperekedwa ndi magetsi zimatha kugwiritsidwa ntchito.

Monga valavu ya servo, itatha ntchito yotsekedwa, nthawi zonse imakhala pafupi ndi zero.Panthawiyi, woyendetsa ndege (kapena panopa pa valavu imodzi) ndi yochepa kwambiri.

Kupyolera mu kusanthula pamwambapa, ndizosavuta kumvetsetsa chifukwa chake kuthamanga kwa injini kumacheperachepera?Chifukwa kuthamanga kwa liwiro, mphamvu yamagetsi yamagetsi imakulirakulira, mphamvu yamagetsi yamagetsi imachepa panthawiyi, ndipo mphamvu ya ampere imachepera.F=BIL.
