Ndeipi musimboti wekushanda kwemota yeBLDC?-1

Mota yeDC isina brushless (BLDC)imota inoshandisa tekinoroji yemagetsi. Inoita kuti ikwanise kumhanya zvakanaka uye kudzora nzvimbo kuburikidza nekudzora kwakanyatsojeka kwemagetsi, zvichiita kuti mota yeDC isina mabhurashi ishande zvakanaka uye yakavimbika. Iyi tekinoroji yemagetsi inobvisa kukweshana kwemabhurashi uye kurasikirwa nesimba mumamota eDC ane mabhurashi, zvichiita kuti ashande zvakanaka. Nheyo yayo yekushanda yakavakirwa pamagetsi emagetsi anoshandiswa pakugadzira magetsi uye tekinoroji yemagetsi. Kana tichienzanisa nemamota eDC ane mabhurashi, mamota eDC asina mabhurashi anowana kushanduka kwemagetsi kuburikidza nemasensa akavakirwa mukati nemacontroller, nokudaro zvichiita kuti ishande zvakanaka, ruzha rushoma uye kushanda kwakaderera kwekuchengetedza.

Mamota eDC asina brush anowanzo kuve nerotor, stator, sensors uye controller. Rotor inowanzo gadzirwa nezvinhu zvemagineti zvinogara zviripo, nepo stator iine waya dzakaita se coils. Kana magetsi achipfuura nepakati pe stator coil, simba remagineti rinogadzirwa rinosangana nezvinhu zvemagineti zvinogara zviripo pa rotor, nokudaro zvichigadzira torque yekumhanyisa rotor kuti itenderere. Ma sensors anowanzo shandiswa kuona nzvimbo nekumhanya kwerotor kuitira kuti controller igone kudzora kutungamira uye hukuru hwemagetsi. Controller ndiyo pfungwa yemota isina brush. Inoshandisa ruzivo rwemhinduro kubva ku sensor kuti iwane electronic commutation chaiyo, nokudaro ichifambisa mota kuti ishande zvakanaka.

Maitiro ekushanda kwemota yeDC isina brushless anogona kukamurwa kuita zvikamu zvakasiyana-siyana: chekutanga, kana magetsi achipfuura nepakati pe stator coil, simba remagineti rinogadzirwa rinosangana nezvinhu zvemagineti zvinogara zviripo pa rotor kuti zvigadzire torque yekusundidzira rotor kuti itenderere. Chechipiri, sensor inoona nzvimbo nekumhanya kwe rotor uye inodzosera ruzivo ku controller. Controller inodzora nemazvo kutungamira nehukuru hwemagetsi zvichibva paruzivo rwemhinduro kubva ku sensor kuti iwane nzvimbo chaiyo nekudzora kumhanya kwe rotor. Chekupedzisira, zvichibva pane nzvimbo uye ruzivo rwekumhanya kwe rotor, controller inodzora nemazvo kutungamira nehukuru hwemagetsi kuti iwane electronic commutation, nokudaro ichiramba ichisundidzira rotor kuti itenderere.

Kana tichienzanisa nemamota eDC akabhurwa echinyakare, mamota eDC asina mabhurashi ane mashandiro akanaka uye akavimbika, saka ave achishandiswa zvakanyanya muminda yakawanda. Muindasitiri yemotokari, yeduSinbadMamota eDC asina mabhurashi anoshandiswa mumadhiraivha emotokari dzemagetsi. Kushanda kwawo zvakanaka uye kwakavimbika kunoita kuti mota dzemagetsi dzikwanise kufamba kwenguva refu uye nekukurumidza. Muminda yemidziyo yemumba, mamota edu eSinbad asina mabhurashi eDC anoshandiswa mumidziyo yakasiyana-siyana yemumba, yakadai semichina yekuwachisa, vacuum cleaners, nezvimwewo. Ruzha rwavo rushoma uye kushanda kwavo zvakanaka kunoita kuti midziyo yemumba ichengetedze simba uye ive neushamwari kune zvakatipoteredza. Pamusoro pezvo, mamota eDC asina mabhurashi anoshandiswawo zvakanyanya muindasitiri otomatiki, aerospace, drones nedzimwe nzvimbo.
