Nzira yekumhanyisa sei mota yeDC brushless?Nzira nhatu dzekudzora kumhanya kwemota isina brushless | MUTUNGAMIRIRI

Zvinoita seidc mota isina mabhurashiKumhanya kwekutonga? Vazhinji vanotanga kushandisa kubvunzana nevatengi vemota isina brushless, dambudziko remota isina brushless rakanyanya muzvigadzirwa zvekurapa, zvekushandisa otomatiki, marobhoti, uye mota mumunda wekushandisa, kuitira kuti vagone kushandisa nzira dzakasiyana dzekutyaira, kudzora kumhanya kwemota isina brushless dc uye dambudziko rekutyaira rine mibvunzo yakawanda,fekitori yemota inodederaKugovana kudzora kumhanya kwemota isina brushless nzira nhatu:

Nzira yekudzora kumhanya kwemota yebrushless dc

Nzira 1: shandisa voltage kudzora kumhanya, torque inonyanya kudzorwa nemagetsi, kazhinji nemota inofambisa mota inoenderana, kushandura voltage inobuda yemutyairi kunogonawo kudzora kumhanya kwemota isina brushless, kana pasina mutyairi, unoda kudzora mota, unoda kuona simba uye kushanda kwemagetsi emota.

Nzira yechipiri: Kudzora kumhanya kwePWM, musimboti wekudzora kumhanya kwePWM wemota yeDC uye musimboti wekudzora kumhanya kwemota yeAC zvakasiyana, haisi nzira yekugadzirisa kumhanya kwemota nefrequency modulation, asi kuburikidza nekugadzirisa nzira yekutyaira voltage pulse width, uye kushanda pamwe nezvimwe zvikamu zvinoenderana zvekuchengetedza simba mudunhu, shanduko ku armature voltage amplitude, kuitira kuti chinangwa chekuchinja kumhanya kwemota yeDC isina brushless chive. Inogadziriswa ne amplitude modulation. Kune nzira mbiri dzekutonga kwePWM:

1. Chiratidzo chePWM chinoshandiswa kudzora nguva yekutungamirwa kwetransistor. Nguva yekutungamirwa kwetransistor yakareba, nguva yebasa icharamba yakareba, uye kumhanya kwemota kuchava kwakakwira.

2. Chiratidzo chekudzora chePWM chinoshandiswa kudzora nguva yekudzima kwetriode, uye voltage yekudzora inochinjwa kuti izvi zviitike.

Nzira 3: kana irimota ine simba dikikumhanya kunogonawo kushandisa resistance (hazvikurudzirwi, nzira yacho iri nyore, nzira iyi chete inogona kuderedza kushanda zvakanaka, saka haitsigire), kumhanya kwemota nesimba guru hakugone kushandisa resistance, nekuti inoda resistance diki ine simba guru (resistance inoshanda nemota idiki kwazvo), resistance yakaipa kuwana uye kushanda kwemhinduro kwakaderera zvakanyanya, zviri nani kutsvaga madhiraivha emota asina brushless dc.

Ndinovimba nzira nhatu dziri pamusoro apa dzemota isina mabhurashi yeDCKudzora kumhanya kwemotokari kunogona kukupa rubatsiro nekukurudzira.

Zviri pamusoro apa ndezvekudzora kumhanya kwemota ye dc isina brushless nenzira nhatu idzi, ndinovimba mune rubatsiro; Isu tiri microfekitori yemotokari inodedera, zvigadzirwa ndeizvi:mota yekudedera yakatsetseka,injini yekudzungudza yeiphone 6s,injini yekudzungudza yeiphone 7;Ndinovimba munogona kutibata!
