I-Brushless vs Brushed Motors: Iyiphi Efanele Iphrojekthi Yakho?

Isingeniso

Izinhlobo ezimbili ezijwayelekile zama-DC motors ama-brushed motors nama-brushless motors (BLDC motors). Njengoba igama lisho, izinjini ezibhulashiwe zisebenzisa amabhulashi ukuze zihambe lapho ziya khona, zivumela injini ukuthi ijikeleze. Ngokuphambene, ama-Brushless motors ashintsha umsebenzi womshini ngokulawula i-electronic. Zombili lezi zinhlobo zisebenza ngesimiso esifanayo, okungukuthi ukukhanga kazibuthe kanye ne-repulsion kazibuthe phakathi kwekhoyili nomazibuthe unomphela. Ngayinye inezinzuzo zayo kanye nokubi, okungase kube nomthelela ekukhetheni kwakho ngokusekelwe ezidingweni ezithile zesicelo sakho. Ukuqonda umehluko phakathi kwama-DC motors axutshwe nama-brushless DC motors kubalulekile ekuhloleni ukusebenza kwawo. Isinqumo sokukhetha uhlobo olulodwa kunolunye sisekelwe ezimisweni ezihlukahlukene, okuhlanganisa ukusebenza kahle, ubude bokuphila kanye nezindleko.

Izici ezibalulekile zomehluko phakathi kwe-brushless ne-brushless DC Motor:

#1. Ukusebenza Okungcono

Amamotho angenabhulashi asebenza kahle kakhulu kunamamotho abhulashiwe. Baguqula amandla kagesi abe amandla emishini ngokunemba okukhulu, ngaleyo ndlela behlise ukumosheka kwamandla. Ngokungafani namamotho e-DC abhulashiwe, ama-brushless motors awaboni ukungqubuzana noma ukulahlekelwa kwamandla okuhlobene namabhulashi nabagibeli. Lokhu kuthuthukisa ukusebenza, kunweba isikhathi sokusebenza, futhi kunciphisa ukusetshenziswa kwamandla.

Ngakolunye uhlangothi, amamotho amabhulashi abhekwa njengasebenza kahle kakhulu kunamamotho e-DC angama-brushless ngenxa yokulahlekelwa amandla okuhambisana nokungqubuzana nokudluliswa kwamandla ngohlelo lwabahambisi.

#2. Isondlo Nokuphila Isikhathi Eside

Ama-motor angama-brushlesszinezingxenye ezimbalwa ezihambayo futhi zintula uxhumo lwemishini, okuholela ekuphileni ende kanye nokuncipha kwezidingo zokulungisa. Ukungabikho kwamabhulashi kuqeda izinkinga ezihambisana nokuguga kwebhulashi nezinye izinkinga zokunakekela. Ngakho-ke, ama-brushless motors ngokuvamile ayinketho engabizi kakhulu kubasebenzisi.

Ukwengeza, ama-motor ama-brushed adinga ukunakekelwa okwengeziwe ngenxa yokuguga nokudabuka kumabhulashi kanye ne-commutator, okungaholela ekunciphiseni ukusebenza kanye nezinkinga zemoto. Ukugcina ukusebenza kahle, amabhulashi adinga ukushintshwa njalo.

#3. Umsindo nokudlidliza

Kumamotho angama-brushless, amandla asongayo angalawulwa, okusiza ukunciphisa ukushaywa kwe-torque okungadala ukudlidliza nomsindo wemishini. Ngakho-ke, ama-brushless motors ngokuvamile akhiqiza umsindo omncane nokudlidliza kunamamotho abhulashiwe. ngoba abanawo amabhulashi noma abagibeli. Ukwehliswa kokudlidliza nomsindo kuthuthukisa ukunethezeka komsebenzisi futhi kunciphisa ukuguga nokuguga ngokusetshenziswa isikhathi eside.

Enjinini ye-DC ebhulashiwe, amabhulashi kanye nesihambisi zisebenza ndawonye njengendlela yokushintsha. Lapho injini isebenza, lezi zinguquko zihlala zivuleka futhi zivaleka. Le nqubo ivumela imisinga ephezulu ukuthi igeleze nge-inductive rotor windings, ikhiqize umsindo omncane kagesi ngenxa yokugeleza okukhulu kwamanje.

#4. Izindleko Nokuyinkimbinkimbi

Amamotho e-brushless avame ukubiza kakhulu futhi ayinkimbinkimbi ngenxa yesistimu yokulawula ye-elekthronikhi yokuhamba. Intengo ephakeme yama-brushless DC motors uma kuqhathaniswaama-brush motors e-DCikakhulukazi kungenxa yezinto zikagesi ezithuthukisiwe ezihilelekile ekwakhiweni kwazo.

#5. Ukuklama nokusebenza

Ama-brushless DC motors awazihambisi ngokwawo. Zidinga i-drive circuit esebenzisa ama-transistors ukulawula ukugeleza kwamanje kumakhoyili ama-motor winding. Lezi zinjini zisebenzisa izilawuli ze-elekthronikhi nezinzwa ze-Hall effect ukuze zilawule amandla amanje kuma-windings, kunokuthembela ekuxhumekeni kwemishini.

Amamotho ama-DC axutshiwe azishintsha ngokwawo, okusho ukuthi awadingi umjikelezo womshayeli ukuze asebenze. Esikhundleni salokho, basebenzisa amabhulashi emishini kanye nabagibeli ukuze balawule amandla amanje kuma-windings, ngaleyo ndlela bakhe insimu kazibuthe. Le nkundla kazibuthe idala i-torque, ibangele ukuthi injini ijikeleze.

#6. Izinhlelo zokusebenza

Njengezindleko zevibration motorsfuthi izinto zikagesi ezihambisana nazo ziyaqhubeka nokuncipha, isidingo samamotho ama-brushless nama-motor ama-brushed siyakhula. Amamotho ama-Brushless adume kakhulu ngamawashi ahlakaniphile, amadivaysi ezokwelapha, izinto zobuhle, amarobhothi, njll.

Kepha kusenezindawo lapho ama-motor abhrashiwe enza umqondo owengeziwe. Kunokusetshenziswa okukhulu kwamamotho ama-brushed kuma-smartphones, ugwayi we-elekthronikhi, izilawuli zemidlalo yevidiyo, izibhulashi zamehlo, njll.
