1. Brushed dc mota

Mumamotor akabhurashwa izvi zvinoitwa neinotenderedza chinja pane shaft yemota inonzi commutator.Iyo ine silinda inotenderera kana dhisiki yakakamurwa kuita akawanda masimbi ekubatanidza zvikamu pane rotor.Zvikamu zvakabatanidzwa kune conductor windings pane rotor.Mabhii maviri kana anopfuura akamira anonzi mabhurashi, akagadzirwa neconductor akapfava senge graphite, anodzvanya achipikisa commutator, achiita kutsvedza kwemagetsi kubata nezvikamu zvinotevedzana sezvo rota inotenderera.Mabhurashi anosarudza kupa magetsi kune ma windings.Sezvo rotor inotenderera, mufambisi anosarudza mhepo yakasiyana-siyana uye inotungamira ikozvino inoshandiswa kune yakapiwa mhepo kuitira kuti rotor regineti inoramba iine misaligned ne stator uye inogadzira torque mune imwe nzira.

2. Brushless dc mota

Mune brushless DC motors, yemagetsi servo system inotsiva iyo mechanic commutator contacts.Sensor yemagetsi inoona kona ye rotor uye inodzora semiconductor switch senge transistors inochinja ikozvino kuburikidza nemamhepo, kana kudzosera kwainoenda kune yazvino kana, mune mamwe mamotor kuidzima, pakona chaiyo kuitira kuti magetsi emagetsi agadzire torque mune imwe. direction.Kubviswa kweiyo inotsvedza yekubata inobvumira brushless motors kuve nekushomeka kudiki uye hupenyu hurefu;hupenyu hwavo hwekushanda hunoganhurwa chete nehupenyu hwemabhengi avo.

Brushed DC motors inogadzira torque yakanyanya kana yakamira, inodzika mutsetse sezvo velocity inowedzera.Zvimwe zvipimo zvemabhurashi motors zvinogona kukundwa nema brushless motors;dzinosanganisira kukwirira kwepamusoro uye kuderera kwekusagadzikana kune mechanical kupfeka.Aya mabhenefiti anouya nemutengo wezvinogona kushomeka, zvakanyanya kuomarara, uye zvinodhura kudzora zvemagetsi.

Iyo yakajairwa brushless mota ine magineti echigarire anotenderera akatenderedza armature, achibvisa matambudziko ane chekuita nekubatanidza ikozvino kune inofamba armature.Yemagetsi controller inotsiva iyo commutator gungano re brushed DC mota, iyo inoramba ichichinja chikamu kuenda kuma windings kuti mota irambe ichitenderera.Iyo controller inoita yakafanana nguva yekugovera simba nekushandisa yakasimba-nyika dunhu kwete iyo commutator system.

Brushless motors inopa mabhenefiti akati wandei pamusoro pe brushed DC motors, kusanganisira yakakwira torque kune huremu reshiyo, kuwedzera kushanda zvakanaka kugadzira torque yakawanda pa watt, kuwedzera kuvimbika, kuderedzwa ruzha, hupenyu hurefu nekubvisa bhurashi uye kukukurwa kwevatambi, kubviswa kweiyo ionizing sparks kubva
commutator, uye kudzikiswa kwese kwe electromagnetic interference (EMI).Pasina mhepo pa rotor, haisi pasi pemasimba e centrifugal, uye nokuti mhepo inotenderera inotsigirwa neimba, inogona kunyoroveswa nekufambisa, inoda kuti mhepo irege kupinda mukati memotokari kuti itonhorere.Izvi zvinoreva kuti zvemukati zvemotor zvinogona kuvharirwa zvachose uye kuchengetedzwa kubva kutsvina kana zvimwe zvinhu zvekunze.

Brushless mota commutation inogona kuitwa musoftware uchishandisa microcontroller, kana neimwe nzira inogona kuitwa uchishandisa analog kana dijitari maseketi.Kuchinjana nemagetsi pachinzvimbo chebhurashi kunobvumira kuchinjika kukuru uye kugona kusingawanikwe nebrushed DC motors, kusanganisira kumhanya kumisa, microstepping operation yeinononoka uye yakanaka motion control, uye torque yekubatisa kana yakamira.Controller software inogona kugadziridzwa kune chaiyo mota iri kushandiswa mukushandisa, zvichikonzera hukuru hwekuchinja.

Iro simba repamusoro rinogona kuiswa kune brushless mota rinoganhurwa nekupisa chete; [kureva kunodiwa] kupisa kwakanyanya kunopedza magineti uye kunokuvadza kuvharwa kwemhepo.

Kana uchishandura magetsi kuita magetsi emagetsi, brushless motors inoshanda zvakanyanya kupfuura brushed motors kunyanya nekuda kwekushaikwa kwemabhurashi, izvo zvinoderedza kurasikirwa kwemagetsi nekuda kwekukweshana.Iko kukwidziridzwa kushanda kwakakura munzvimbo isina-mutoro uye yakaderera-mutoro matunhu emota's performance curve.

Mamiriro uye zvinodiwa umo vagadziri vanoshandisa brushless-mhando DC mota dzinosanganisira kuchengetedza-isina mashandiro, kumhanya kwakanyanya, uye kushanda uko kupenya kune njodzi (kureva nzvimbo dzinoputika) kana zvinogona kukanganisa midziyo yemagetsi.

Kuvakwa kwebhurashi mota inofanana neinotsika mota, asi mota dzine misiyano yakakosha nekuda kwekusiyana kwekuita uye kushanda.Nepo ma stepper motors achiwanzo miswa ne rotor mune yakatsanangurwa angular chinzvimbo, brushless mota inowanzoitirwa kuburitsa kutenderera kutenderera.Mhando mbiri dzemota dzinogona kunge dziine rotor chinzvimbo sensor yemukati mhinduro.Ose ari maviri mota inotsika uye yakanyatsogadzirwa brushless mota inogona kubata inogumira torque pa zero RPM.
