Uma kuqhathaniswa ne-DC motor kanye ne-asynchronous motor, izici ezibalulekile zobuchwepheshe ze-Brushless DC motor yilezi:

1.Izici zokusebenza ze-DC motor zitholwa ngokulawulwa kwe-elekthronikhi.Inokulawulwa kangcono kanye nebanga lejubane elibanzi.

2.Imininingwane yempendulo yesikhundla se-Rotor kanye nomshayeli we-inverter we-electronic multiphase kuyadingeka.

3.Essentially, i-AC motor ingasebenza ngesivinini esikhulu ngaphandle kwenhlansi nokuhuzuka kwebhulashi kanye ne-commutator.Inokwethenjelwa okuphezulu, impilo ende yokusebenza futhi asikho isidingo sokunakekelwa.

I-4.Brushless DC motor inesici samandla aphezulu, akukho ukulahleka kwerotha nokushisa, nokusebenza kahle okuphezulu: uma kuqhathaniswa nedatha, ukusebenza kahle kwe-7.5 kW motor asynchronous kungu-86.4%, nokusebenza kahle komthamo ofanayo we-brushless DC motor kungafinyelela ku-92.4% .

5.Kumele kube nezingxenye zokulawula zikagesi, izindleko eziphelele ziphezulu kunemoto ye-DC.

Ngokuyinhloko kunezinhlobo ezimbili zamamotho asetshenziswa ohlelweni lwe-AC: injini yokungenisa kanye ne-synchronous motor ehlala njalo uzibuthe.I-Permanent magnet synchronous motor ingahlukaniswa ibe yi-sinusoidal back EMF unomphela uzibuthe we-synchronous motor (PMSM) kanye ne-square wave back EMF brushless DC motor (BLDCM) ngokuvumelana nesimiso sokusebenza esihlukile.Ukuze imodi yabo yokushayela yamanje neyokulawula ihluke.

I-EMF yangemuva ye-sinusoidal unomphela uzibuthe motor synchronous is sinusoidal.Ukuze i-motor ikhiqize i-torque ebushelelezi, i-current egeleza kuma-motor winding kumele ibe yi-sinusoidal.Ngakho-ke, isignali yesimo se-rotor eqhubekayo kufanele yaziwe, futhi i-inverter inganikeza i-voltage ye-sinusoidal noma yamanje ku-motor.Ngakho-ke, i-PMSM idinga ukusebenzisa amandla kagesi aphezulu noma amanje.Ukulungiswa kwesifaki khodi sendawo noma isixazululi nakho kuyinkimbinkimbi kakhulu.

I-BLDCM ayidingi inzwa yendawo yokulungiswa okuphezulu, idivayisi yempendulo ilula, futhi i-algorithm yokulawula ilula ngokuqhathaniswa.Ngaphezu kwalokho, igebe lomoya kazibuthe le-BLDCM trapezoidal wave lisebenza kahle kakhulu kunalelo le-PMSM sinusoidal wave, futhi ukuminyana kwamandla we-BLDCM kungaphezulu kwalokho kwe-PMSM.Ngakho-ke, ukusetshenziswa kanye nocwaningo lwezibuthe unomphela brushless DC motor uthole ukunakwa okwengeziwe.
