A brushless DC mota (BLDC)imota inoshandisa tekinoroji yekuchinjanisa tekinoroji. Iyo inowana chaiyo kumhanya uye chinzvimbo chekutonga kuburikidza neyakajeka yemagetsi kutonga, ichiita iyo brushless DC mota ishande uye yakavimbika. Iyi tekinoroji yekufambisa tekinoroji inobvisa kukweshera kwebhurashi uye kurasikirwa kwesimba mune yechinyakare brushed DC mota, ichivabvumira kuti vashande zvakanyanya. Iyo nheyo yekushanda yakavakirwa pamagetsi emagetsi induction uye zvemagetsi commutation tekinoroji. Kuenzaniswa neyechinyakare brushed DC mota, brushless DC motors inowana zvemagetsi commutation kuburikidza neakavakirwa-mukati ma sensors uye controller, nekudaro achiwana hunyanzvi hwepamusoro, ruzha rwakaderera uye kushanda kwakaderera kwekugadzirisa.
Brushless DC mota dzinowanzo sanganisira rotor, stator, sensors uye controller. Iyo rotor inowanzo gadzirwa nekusingaperi magineti zvinhu, nepo stator ine macoil ewaya. Kana yazvino ichipfuura nepakati peiyo stator coil, iyo magineti inogadzirwa inopindirana neanogara magineti zvinhu pane rotor, nekudaro ichigadzira torque kutyaira rotor kutenderera. Sensors inowanzoshandiswa kuona nzvimbo uye kukurumidza kwe rotor kuitira kuti mutongi anogona kunyatso kudzora hutungamiri uye ukuru hwezvino. Iyo controller ndiyo uropi hweiyo brushless mota. Inoshandisa ruzivo rwemhinduro kubva kune sensor kuti iwane chaiyo yemagetsi commutation, nekudaro ichityaira mota kuti imhanye nemazvo.
Maitiro ekushanda kweiyo brushless DC mota inogona kukamurwa kuita matanho akati wandei: kutanga, kana yazvino ichipfuura nepakati peiyo stator coil, iyo inogadzirwa magineti inopindirana neanogara magineti zvinhu pa rotor kugadzira torque kutyaira rotor kutenderera. Chechipiri, iyo sensor inoona nzvimbo uye kukurumidza kwe rotor uye inodyisa ruzivo kudzokera kumutongi. Iyo controller inonyatso kudzora kutungamira uye saizi yezvino zvichibva paruzivo rwemhinduro kubva kune sensor kuti uwane chaiyo chinzvimbo uye kukurumidza kutonga kwe rotor. Pakupedzisira, zvichienderana nechinzvimbo uye ruzivo rwekukurumidzira kwe rotor, mutongi anonyatso kudzora kutungamira uye ukuru hwemazuva ano kuti awane kushandiswa kwemagetsi, nokudaro achienderera mberi achityaira rotor kutenderera.
Kuenzaniswa neyakajairwa brushed DC mota, brushless DC mota dzine hunyanzvi hwepamusoro uye kuvimbika, saka dzakashandiswa zvakanyanya muminda yakawanda. Muindasitiri yemotokari, yeduSinbadbrushless DC mota dzinoshandiswa mumadhiraivha masisitimu emotokari dzemagetsi. Kuita kwavo kwakanaka uye kwakavimbika kunoita kuti mota dzemagetsi dziwane kureba kwekufamba uye kukurumidza kukurumidza. Mumunda wemidziyo yemumba, yedu Sinbad brushless DC motors inoshandiswa mumidziyo yakasiyana-siyana yepamba, yakadai semichina yekuwachisa, vacuum cleaners, nezvimwewo. Ruzha rwavo rwakadzikira uye kugona kukuru kunoita kuti midziyo yemumba iwedzere kuchengetedza simba uye kutenderedza nharaunda. Pamusoro pezvo, brushless DC mota dzinoshandiswawo zvakanyanya mumaindasitiri otomatiki, aerospace, drones uye mamwe minda.
Kazhinji,brushless DC motavave chikamu chakakosha chenzvimbo yemazuva ano yekuisa magetsi nemabhenefiti avo senge kunyatsoita basa, ruzha rwakaderera, hupenyu hurefu, uye kutonga chaiko. Kushandiswa kwavo kwakakura mundima dzakasiyana-siyana kunosimudzira brushless DC mota tekinoroji. budiriro uye hutsva.
