Iimoto ezingenabhrashi vs ezixutyiweyo: Yeyiphi efanelekileyo kwiprojekthi yakho?

Intshayelelo

Iindidi ezimbini eziqhelekileyo zeemoto zeDC ziimoto ezixutyiweyo kunye neemoto ezingenamabhrashi (iimoto zeBLDC). Njengoko igama lisitsho, iimoto ezixutyiweyo zisebenzisa iibrashi ukutshintsha indlela, zivumela imoto ukuba ijikeleze. Ngokwahlukileyo koko, iimoto ezingenamabhrashi zithatha indawo yomsebenzi wokutshintsha koomatshini ngolawulo lwe-elektroniki. Zombini ezi ntlobo zisebenza ngomgaqo ofanayo, oko kukuthi ukutsalana kwemagnethi kunye nokugxothwa kwemagnethi phakathi kwekhoyili kunye nemagnethi esisigxina. Nganye inezibonelelo kunye neengxaki zayo, ezinokuchaphazela ukhetho lwakho ngokusekelwe kwiimfuno ezithile zesicelo sakho. Ukuqonda umahluko phakathi kweemoto zeDC ezixutyiweyo kunye neemoto zeDC ezingenamabhrashi kubalulekile ekuvavanyeni ukusebenza kwazo. Isigqibo sokukhetha uhlobo olunye kunolunye sisekelwe kwiindlela ezahlukeneyo, kubandakanya ukusebenza kakuhle, ixesha lokuphila kunye neendleko.

Izinto ezibalulekileyo zokwenza umahluko phakathi kweMoto yeDC ebhrashiweyo nengenabhrashi:

#1. Ukusebenza kakuhle ngcono

Iimoto ezingenabhrashi zisebenza kakuhle kuneemoto ezibrashiweyo. Ziguqula amandla ombane abe ngamandla oomatshini ngokuchanekileyo, ngaloo ndlela zinciphisa inkunkuma yamandla. Ngokungafaniyo neemoto zeDC ezibrashiweyo, iimoto ezingenabhrashi azifumani ukungqubana okanye ukulahleka kwamandla okunxulunyaniswa neebrashi kunye nee-commutators. Oku kuphucula ukusebenza, kwandisa ixesha lokusebenza, kwaye kunciphisa ukusetyenziswa kwamandla.

Ngokwahlukileyo koko, iimoto ezixutyiweyo zithathwa njengezingasebenzi kakuhle kuneemoto zeDC ezingenamabhulashi ngenxa yokulahleka kwamandla okunxulunyaniswa nokungqubana kunye nokudluliselwa kwamandla kwinkqubo ye-commutator.

#2. Ukugcinwa kunye nobude bexesha elide

Iimoto ezingenabhrashiZincinci iindawo ezishukumayo kwaye azinazo iintambo zonxibelelwano, nto leyo ebangela ukuba zihlale ixesha elide kwaye zinciphise iimfuno zolondolozo. Ukungabikho kweebhrashi kususa iingxaki ezinxulumene nokuguguleka kweebhrashi kunye neminye imiba yolondolozo. Ke ngoko, iimoto ezingenabhrashi zihlala ziyindlela engabizi kakhulu kubasebenzisi.

Ukongeza, iimoto ezixutyiweyo zifuna ukulungiswa ngakumbi ngenxa yokuguguleka kweebhrashi kunye ne-commutator, nto leyo enokubangela ukuba ukusebenza kwazo kunciphe kwaye kubekho iingxaki zeemoto. Ukuze kugcinwe ukusebenza kakuhle, iibhrashi kufuneka zitshintshwe rhoqo.

#3. Ingxolo kunye nokungcangcazela

Kwiimoto ezingenamabhrashi, umsinga wokujika ungalawulwa, nto leyo enceda ekunciphiseni ukushukuma kwe-torque okunokubangela ukungcangcazela kunye nengxolo yoomatshini. Ke ngoko, iimoto ezingenamabhrashi zihlala zivelisa ingxolo encinci kunye nokungcangcazela kuneemoto ezinebhrashi. kuba azinazo iibhrashi okanye ii-commutator. Ukunciphisa ukungcangcazela kunye nengxolo kuphucula intuthuzelo yomsebenzisi kwaye kunciphisa ukuguguleka xa kusetyenzwa ixesha elide.

Kwimoto ye-DC exutyiweyo, iibhrashi kunye ne-commutator zisebenza kunye njengendlela yokutshintsha. Xa imoto isebenza, ezi switshi zihlala zivuleka kwaye zivala. Le nkqubo ivumela imisinga ephezulu ukuba ihambe ngee-inductive rotor windings, ivelise ingxolo encinci yombane ngenxa yokuhamba komsinga omkhulu.

#4. Ixabiso kunye nobunzima

Iimoto ezingenabhrashi zidla ngokuba zibiza kakhulu kwaye zintsonkothile ngenxa yenkqubo yokulawula ye-elektroniki yokutshintsha. Ixabiso eliphezulu leemoto ze-DC ezingenabhrashi xa lithelekiswa neiimoto zeDC ezixutyiweyoikakhulu kungenxa yezixhobo ze-elektroniki eziphambili ezibandakanyekayo kuyilo lwazo.

#5. Uyilo kunye nokusebenza

Iimoto zeDC ezingenabhrashi azizitshintshi ngokwazo. Zifuna isekethe yokuqhuba esebenzisa ii-transistors ukulawula umsinga ohamba ngee-coils ze-motor winding. Ezi moto zisebenzisa ulawulo lwe-elektroniki kunye nee-Hall effect sensors ukulawula umsinga kwii-windings, endaweni yokuxhomekeka kunxibelelwano lwe-mechanical.

Iimoto ze-DC ezixutyiweyo ziyazitshintsha ngokwazo, oko kuthetha ukuba azidingi circuit yomqhubi ukuze zisebenze. Endaweni yoko, zisebenzisa iibrashi zoomatshini kunye nee-commutators ukulawula umsinga kwii-windings, ngaloo ndlela zenza i-magnetic field. Le magnetic field idala i-torque, nto leyo ebangela ukuba i-motor ijikeleze.

#6. Izicelo

Njengoko ixabiso leiimoto zokungcangcazelakwaye izixhobo zabo ze-elektroniki ezihambelana nazo ziyaqhubeka nokuncipha, imfuno yeemoto ezingenamabhrashi kunye neemoto ezibrashiweyo iyanda. Iimoto ezingenamabhrashi zithandwa kakhulu kwiismartwatch, izixhobo zonyango, izixhobo zobuhle, iirobhothi, njl.njl.

Kodwa kusekho iindawo apho iimoto ezixutyiweyo zinentsingiselo ngakumbi. Kukho ukusetyenziswa okukhulu kweemoto ezixutyiweyo kwiifowuni eziphathwayo, ii-e-cigarettes, ii-video game controllers, ii-eye massagers, njl.njl.
