Ama-Brushless Motors vs Brushed Motors: Yikuphi Okufanelekile Kuphrojekthi Yakho?

Isingeniso

Izinhlobo ezimbili ezivamile zama-motor e-DC ama-motor axutshwe kanye nama-motor angenamabhulashi (ama-motor e-BLDC). Njengoba igama lisho, ama-motor axutshwe asebenzisa amabhulashi ukushintsha indlela, okuvumela imoto ukuthi ijikeleze. Ngokuphambene nalokho, ama-motor angenamabhulashi athatha indawo yomsebenzi wokushintsha komshini ngokulawula kwe-elekthronikhi. Zombili izinhlobo zisebenza ngesimiso esifanayo, okungukuthi ukukhanga kwamagnetic kanye nokuxoshwa kwamagnetic phakathi kwekhoyili kanye ne-magnet ehlala njalo. Ngayinye inezinzuzo zayo kanye nokungalungi kwayo, okungathonya ukukhetha kwakho ngokusekelwe ezidingweni ezithile zesicelo sakho. Ukuqonda umehluko phakathi kwama-motor e-DC axutshwe kanye nama-motor e-DC angenamabhulashi kubalulekile ekuhloleni ukusebenza kwawo. Isinqumo sokukhetha uhlobo olulodwa kunolunye sisekelwe ezindinganisweni ezahlukahlukene, kufaka phakathi ukusebenza kahle, isikhathi sokuphila kanye nezindleko.

Izici ezibalulekile zomehluko phakathi kwe-DC Motor ebhulashiwe nengenabhulashi:

#1. Ukusebenza Kahle Kangcono

Ama-motor angenamabhulashi asebenza kahle kakhulu kunezinjini ezixutshwe ngebhulashi. Aguqula amandla kagesi abe amandla omshini ngokunemba okukhulu, ngaleyo ndlela anciphise imfucuza yamandla. Ngokungafani nama-motor e-DC axutshwe ngebhulashi, ama-motor angenamabhulashi awazwani nokungqubuzana noma ukulahlekelwa amandla okuhambisana namabhulashi nama-commutator. Lokhu kuthuthukisa ukusebenza, kwandise isikhathi sokusebenza, futhi kunciphisa ukusetshenziswa kwamandla.

Ngokuphambene nalokho, ama-motor axutshwe abhekwa njengangasebenzi kahle kune-motor ye-DC engenama-brush ngenxa yokulahlekelwa amandla okuhambisana nokungqubuzana kanye nokudluliswa kwamandla ohlelweni lwe-commutator.

#2. Ukugcinwa Nokuphila Isikhathi Eside

Ama-motor angenamabhulashizinezingxenye ezimbalwa ezihambayo futhi azinazo izixhumanisi zemishini, okuholela ekuphileni isikhathi eside kanye nezidingo zokunakekelwa ezincishisiwe. Ukungabikho kwamabhulashi kuqeda izinkinga ezihlobene nokuguguleka kwamabhulashi kanye nezinye izinkinga zokunakekelwa. Ngakho-ke, ama-motor angenamabhulashi ngokuvamile ayindlela engabizi kakhulu kubasebenzisi.

Ngaphezu kwalokho, ama-motor axutshwe ngebhulashi adinga ukulungiswa okwengeziwe ngenxa yokuguga nokuqhekeka kwamabhulashi kanye ne-commutator, okungaholela ekunciphiseni ukusebenza kahle kanye nezinkinga ze-motor. Ukuze kugcinwe ukusebenza kahle, amabhulashi adinga ukushintshwa njalo.

#3. Umsindo Nokudlidliza

Kuma-motor angenamabhulashi, ugesi ojikelezayo ungalawulwa, okusiza ukunciphisa ukushaya kwe-torque okungabangela ukudlidliza nomsindo womshini. Ngakho-ke, ama-motor angenamabhulashi ngokuvamile akhiqiza umsindo omncane nokudlidliza kunezinjini ezihlikihliwe. ngoba azinawo amabhulashi noma ama-commutator. Ukunciphisa ukudlidliza nomsindo kuthuthukisa induduzo yomsebenzisi futhi kunciphisa ukuguguleka nokuguga uma kusetshenziswa isikhathi eside.

Ku-motor ye-DC ebhulashiwe, amabhulashi kanye ne-commutator basebenza ndawonye njengendlela yokushintsha. Uma injini isebenza, lawa maswishi avuleka futhi avalwa njalo. Le nqubo ivumela ukuthi ama-current aphezulu ageleze ngokusebenzisa ama-rotor windings e-inductive, akhiqize umsindo omncane kagesi ngenxa yokugeleza okukhulu kwamanje.

#4. Izindleko Nobunzima

Ama-motor angenamabhulashi avame ukubiza kakhulu futhi abe yinkimbinkimbi ngenxa yesistimu yokulawula kagesi yokushintshashintsha. Intengo ephezulu yama-motor angenamabhulashi e-DC uma iqhathaniswa ne-ama-motor e-DC axutshweikakhulukazi kungenxa ye-elekthronikhi ethuthukisiwe ehilelekile ekwakhiweni kwayo.

#5. Umklamo kanye Nokusebenza

Ama-motor e-DC angenamabhulashi awakwazi ukuzishintsha. Adinga i-drive circuit esebenzisa ama-transistors ukulawula ugesi ogeleza ngama-coil omoya ojikelezayo. Lawa ma-motor asebenzisa izilawuli ze-elekthronikhi kanye nezinzwa ze-Hall effect ukuphatha ugesi kuma-windings, kunokuthembela ekuxhumekeni kwemishini.

Ama-motor e-DC axutshwe ngebhulashi ayazishintsha wona, okusho ukuthi awadingi isekethe yomshayeli ukuze asebenze. Esikhundleni salokho, asebenzisa amabhulashi omshini kanye nama-commutator ukulawula ugesi kuma-windings, ngaleyo ndlela adale insimu yamagnetic. Le nsimu yamagnetic idala i-torque, okwenza imoto ijikeleze.

#6. Izicelo

Njengoba izindleko zeama-motor okudlidlizafuthi izinto zobuchwepheshe ezihambisana nazo ziyaqhubeka nokuncipha, isidingo sama-motor angenamabhulashi kanye nama-motor afakwe ibhulashi siyanda. Ama-motor angenamabhulashi athandwa kakhulu ngama-smartwatch, amadivayisi ezokwelapha, amadivayisi obuhle, amarobhothi, njll.

Kodwa kusenezindawo lapho ama-motor axutshwe kahle enza khona umqondo. Kukhona ukusetshenziswa okukhulu kwama-motor axutshwe kahle kuma-smartphone, kuma-e-cigarette, kuma-video game controllers, kuma-eye massager, njll.
