Kudziwa mfundo zogwirira ntchito zamagalimoto a brushless ndi brushless motor

Brush motor ntchito mfundo

Kapangidwe kake kabrushless motandi stator + rotor + burashi, ndipo torque imapezeka pozungulira maginito kuti itulutse mphamvu ya kinetic. Burashi imalumikizana nthawi zonse ndi commutator kuti ipereke magetsi ndikusintha gawo mozungulira.

Brush motor AMAGWIRITSA NTCHITO kusintha kwamakina, maginito samasuntha, kuzungulira koyilo. injini ikagwira ntchito, koyilo ndi choyendetsa zimazungulira, pomwe chitsulo cha maginito ndi burashi ya kaboni sizisintha.Kusintha kosinthika kwa koyilo komweko komweko kumatheka ndi commutator ndi burashi yomwe imazungulira ndi mota.

Mu mota ya burashi, njirayi ndikuphatikiza malekezero amagetsi awiri a koyilo, kenako, yokonzedwa mu mphete, yolekanitsidwa ndi zida zotchingira pakati pa wina ndi mzake, kupanga chilichonse chonga silinda, kukhala organic mobwerezabwereza ndi shaft yamoto. , magetsi kudzera pa nsanamira yaing'ono iwiri yopangidwa ndi carbon (carbon burashi), pansi pa mphamvu ya masika, kuchokera kumalo awiri enieni okhazikika, kukakamiza pamagetsi amphamvu, mfundo ziwiri za koyilo yozungulira yozungulira mpaka koyilo ya seti ya magetsi.

Mongagalimotoatembenuza, koyilo osiyana kapena mizati osiyana koyilo yemweyo ndi mphamvu pa nthawi zosiyanasiyana, kotero kuti pali oyenera Angle kusiyana pakati ns mzati wa koyilo kupanga maginito ndi ns mzati wa yapafupi okhazikika maginito stator.Minda ya maginito imakopana ndikuthamangitsana wina ndi mzake, kutulutsa mphamvu ndikukankhira injini kuti itembenuke. Mpweya wa carbon electrode umayenda pamutu wa waya ngati burashi pamwamba pa chinthu, motero dzina lakuti "brush".

Kuthamanga ndi wina ndi mzake kumayambitsa kukangana ndi kutayika kwa maburashi a carbon, omwe amafunika kusinthidwa nthawi zonse.Kusintha ndi kutseka pakati pa burashi ya carbon ndi mutu wa waya wa koyilo kungayambitse kuphulika kwa magetsi, kuphulika kwa electromagnetic ndi kusokoneza zipangizo zamagetsi.

Brushless motor ntchito mfundo

Mu mota yopanda burashi, kusinthaku kumachitika ndi gawo lowongolera mu owongolera (nthawi zambiri hall sensor + controller, ndiukadaulo wapamwamba kwambiri ndi maginito encoder).

Galimoto yopanda maburashi AMAGWIRITSA NTCHITO choyendera chamagetsi, koyilo sikuyenda, maginito amazungulira.Galimoto yopanda maburashi IMAGWIRITSA NTCHITO zida zamagetsi kuti zizindikire malo a maginito a maginito okhazikika kudzera mu holo SS2712.Malinga ndi lingaliro ili, dera lamagetsi limagwiritsidwa ntchito kusinthira njira yapano mu koyiloyo pa nthawi yoyenera kuonetsetsa kuti mphamvu ya maginito imayendetsedwa m'njira yoyenera kuyendetsa galimoto. Kuchotsa kuipa kwa mota ya brush.

Mabwalowa amatchedwa motor controller.Woyang'anira motor brushless amathanso kuzindikira ntchito zina zomwe sizingachitike ndi mota yopanda mafuta, monga kusintha Angle yosinthira mphamvu, ma braking motor, kupangitsa injini kubwerera kumbuyo, kutseka mota, ndikugwiritsa ntchito chizindikiro cha brake kuti ayimitse magetsi ku motor.Now batri galimoto zamagetsi zamagetsi lock, pakugwiritsa ntchito kwathunthu kwa ntchitozi.

Brushless dc motor ndi chinthu chomwe chimapangidwa ndi ma motor body ndi driver. Popeza brushless dc motor imayendetsedwa munjira yodziwongolera yokha, sizingawonjezepo kuyimba koyambira ku rotor ngati motor synchronous yokhala ndi ma frequency frequency regulation. ndipo katundu wolemetsa amayamba, ndipo sizingayambitse kugwedezeka ndi kutuluka pamene katundu akusintha.

Kusiyana kwa liwiro lamagalimoto pakati pa brashi mota ndi brushless mota

M'malo mwake, kuwongolera kwamitundu iwiri yamagalimoto ndikuwongolera voteji, koma chifukwa brushless dc IMAPHUNZITSA commutator yamagetsi, kotero imatha kutheka ndi kuwongolera kwa digito, ndipo brushless dc imadutsa mpweya wa burashi commutator, pogwiritsa ntchito silicon yoyendetsedwa ndi analogi yachikhalidwe imatha kuwongoleredwa. , yosavuta.

1. Njira yoyendetsera liwiro la mota ya brush ndikusintha voteji yamagetsi amagetsi. Pambuyo posintha, magetsi ndi magetsi amasinthidwa ndi commutator ndi burashi kuti asinthe mphamvu ya maginito opangidwa ndi electrode kuti akwaniritse cholinga chosinthira liwiro. Njirayi imadziwika kuti kuwongolera kuthamanga.

2. Njira yoyendetsera liwiro la motor brushless motor ndikuti mphamvu yamagetsi yamagetsi yamagetsi imakhalabe yosasinthika, chizindikiro chowongolera chakusintha kwamagetsi chimasinthidwa, ndipo kusinthasintha kwa chubu champhamvu kwambiri cha MOS kumasinthidwa ndi microprocessor kuti zindikirani kusintha kwa liwiro.Mchitidwewu umatchedwa kutembenuka pafupipafupi.

Kusiyana kwa magwiridwe antchito

1. Brush motor ili ndi mawonekedwe osavuta, nthawi yayitali yachitukuko komanso ukadaulo wokhwima

Kalelo m'zaka za zana la 19, pamene galimotoyo inabadwa, galimoto yothandiza inali mawonekedwe opanda brushless, omwe ndi ac squirrel-cage asynchronous motor, omwe ankagwiritsidwa ntchito kwambiri pambuyo pa kubadwa kwa alternating current. kuti chitukuko cha umisiri wamagalimoto ndi pang'onopang'ono.Mwamakamaka, brushless dc motor yalephera kuyikidwa muzamalonda.Ndi chitukuko chofulumira cha teknoloji yamagetsi, yakhala ikugwiritsidwa ntchito pang'onopang'ono mpaka zaka zaposachedwapa.M'malo mwake, akadali m'gulu la ac motor.

Brushless motor idabadwa kale, anthu adapanga brushless dc motor.Chifukwa makina opangira ma brushless dc ndi osavuta, osavuta kupanga ndikuwongolera, osavuta kusamalira, osavuta kuwongolera; mota ya DC imakhalanso ndi kuyankha mwachangu, torque yayikulu, komanso imatha kupereka magwiridwe antchito ovotera kuchokera pa liwiro la zero kupita ku liwiro lovotera, chifukwa chake yakhala ikugwiritsidwa ntchito kwambiri ikangotuluka.

2. Makina a brushless dc ali ndi liwiro loyankhira mwachangu komanso torque yayikulu

Dc brushless motor imayamba kuyankha mwachangu, torque yayikulu yoyambira, kusintha kwa liwiro lokhazikika, pafupifupi palibe kugwedezeka komwe kumamveka kuchokera ku zero kupita ku liwiro lalikulu, ndipo imatha kuyendetsa katundu wokulirapo poyambira. Mphamvu yamagetsi ndi yaying'ono, torque yoyambira ndi yaying'ono, phokoso loyambira likumveka, limodzi ndi kugwedezeka kwamphamvu, ndipo katundu woyendetsa ndi wocheperako poyambira.

3. Brushless dc motor imayenda bwino ndipo imakhala ndi mabuleki abwino

Galimoto ya brushless imayendetsedwa ndi kayendetsedwe ka magetsi, kotero kuti chiyambi ndi braking zimakhala zokhazikika, ndipo kuthamanga kosalekeza kumakhala kokhazikika. ndikuwongolera liwiro kudzera pakusintha pafupipafupi.Choncho, brushless motor sikuyenda bwino poyambira ndi braking, ndi kugwedezeka kwakukulu, ndipo idzakhala yokhazikika pamene liwiro liri lokhazikika.

4, dc burashi galimoto kuwongolera molondola ndipamwamba

Dc brushless motor nthawi zambiri imagwiritsidwa ntchito limodzi ndi bokosi lochepetsera ndi decoder kuti mphamvu yotulutsa yagalimoto ikhale yayikulu komanso kuwongolera kolondola kwambiri, kuwongolera bwino kumatha kufika 0.01 mm, pafupifupi kutha kulola magawo osuntha kuyimitsa pamalo aliwonse omwe akufuna. zida ndi dc motor control accuracy.Poti brushless motor sikhazikika poyambira ndi braking, magawo osuntha amayima pazigawo zosiyanasiyana nthawi iliyonse, ndipo malo omwe akufunidwa amatha kuyimitsidwa poyika pini kapena malire.

5, dc brush mtengo wogwiritsa ntchito mota ndi wotsika, kukonza kosavuta

Chifukwa chosavuta cha mota ya brushless dc, mtengo wotsika wopanga, opanga ambiri, ukadaulo wokhwima, womwe umagwiritsidwa ntchito kwambiri, monga mafakitale, zida zamakina, zida zolondola, etc., ngati kulephera kwagalimoto, ingolowetsani burashi ya kaboni. , burashi iliyonse ya kaboni imangofunika madola angapo, teknoloji yotsika mtengo kwambiri.Brushless galimoto yamakono siili yokhwima, mtengo ndi wokwera, kuchuluka kwa ntchito kumakhala kochepa, makamaka kuyenera kukhala mu zipangizo zothamanga nthawi zonse, monga kutembenuka kwafupipafupi mpweya, firiji, ndi zina zotero. , brushless motor kuwonongeka kungasinthidwe kokha.

6, palibe burashi, kusokoneza otsika

Ma motors opanda maburashi amachotsa burashi, kusintha kwachindunji kwambiri ndikuti palibe burashi yamoto yothamanga, motero kuchepetsa kusokoneza kwamagetsi pazida zakutali.

7. Phokoso lochepa ndi ntchito yosalala

Popanda maburashi, motor brushless imakhala ndi mikangano yocheperako panthawi yogwira ntchito, yosalala komanso phokoso lotsika kwambiri, lomwe limathandizira kwambiri kukhazikika kwa magwiridwe antchito.

8. Moyo wautali wautumiki ndi mtengo wotsika wokonza

Zovala zocheperako, zopanda maburashi ndizovala makamaka pamakina, kuchokera pamakina, brushless mota ili pafupifupi mota yopanda kukonza, pakafunika, ingokonzani fumbi.
