Kutheni le nto izixhobo zamandla zisebenzisa iimotor ezibrashiweyo, kodwa hayi iimoto ezingenabrashi?
Kutheni izixhobo zamandla (ezifana nokubhola ngesandla, izigridi ze-engile, njl.njl.) ziqhele ukusebenzisa iimotor ezibrashwayo endaweni yokubaiimotho ezingenabrashi? Ukuqonda, oku ngokwenene akucacanga kwisivakalisi esinye okanye ezibini. Iinjini ze-DC zahlulwe zaba ziinjini ezixutyiweyo kunye neenjini ezingasebenziyo. “Ibrashi” ekhankanywe apha ibhekisa kwiibrashi zekhabhoni.Ijongeka njani ibrashi yekhabhoni? Kutheni iimoto zeDC zifuna iibhrashi zekhabhoni?Uthini umahluko phakathi kweebrashi zekhabhoni nangaphandle?Masijonge phantsi! Umgaqo wemoto ye-DC ebrashiweyo Njengoko kubonisiwe kuMfanekiso 1, lo ngumzekelo wesakhiwo se-DC brush motor.Imagnethi ezimbini ezisisigxina ezichaseneyo, i-coil ibekwe embindini, zombini iziphelo zekhoyili ziqhagamshelwe kumakhonkco obhedu amabini angama-semi-setyhula, iziphelo zombini zamakhonkco obhedu zinxibelelana nebrashi yekhabhoni esisigxina, kwaye ke i-DC idityanisiwe. kuzo zombini iziphelo zebrashi yekhabhoni. ukunikezwa Amandla. Emva kokudibanisa kunikezelo lwamandla, okwangoku kuboniswa ngotolo kuMfanekiso 1.Ngokomthetho wesandla sasekhohlo, ikhoyili etyheli iphantsi komgangatho othe nkqo we-electromagnetic force; Ikhoyili eluhlaza iphantsi kombane othe nkqo owehlayo.I-rotor ye-motor iqala ukujikeleza ngasekunene, kwaye emva kokujikeleza i-90 degrees, njengoko kubonisiwe kuMfanekiso 2: Ngeli xesha, ibrashi yekhabhoni ikwisithuba phakathi kwamakhonkco amabini obhedu, kwaye yonke i-coil loop ayinayo okwangoku.Kodwa phantsi kwesenzo se-inertia, i-rotor iyaqhubeka ijikeleza. Xa i-rotor iphendukela kwindawo engentla phantsi kwesenzo se-inertia, i-coil yangoku iboniswe kuMzobo 3. Ngokomgaqo wesandla sasekhohlo, i-coil eluhlaza okwesibhakabhaka ixhomekeke kwi-vertically upward up force electromagnetic force; Ikhoyili etyheli iphantsi kwamandla ombane othe nkqo ezantsi. I-motor rotor iyaqhubeka nokujikeleza ngasekunene, emva kokujikeleza i-90 degrees, njengoko kubonisiwe kuMfanekiso 4: Ngeli xesha, ibrashi yekhabhoni ikwisithuba phakathi kwamakhonkco amabini obhedu, kwaye akukho okwangoku kuyo yonke i-coil loop.Kodwa phantsi kwesenzo se-inertia, i-rotor iyaqhubeka ijikeleza.Emva koko phinda la manyathelo angasentla, kwaye umjikelo uyaqhubeka. Njengoko kubonisiwe kuMfanekiso 5, lo ngumzekelo wesakhelo somzobo abrushless DC motor. Iqukethe i-stator kunye ne-rotor, apho i-rotor inezibonda zamagnetic; kukho iiseti ezininzi zeekhoyili ezinxeba kwi-stator, kwaye kukho iiseti ezi-6 zeekhoyili emfanekisweni. Xa sidlula okwangoku kwi-stator coils 2 kunye ne-5, iikhoyili ze-2 kunye ne-5 ziya kuvelisa intsimi yamagnetic. I-stator ilingana ne-bar magnet, apho i-2 yi-S (South) pole kunye ne-5 yi-N (North) pole. Ekubeni izibonda zamagnetic zesini esifanayo zikhanga omnye komnye, i-N pole ye-rotor iya kujikeleza kwindawo ye-coil 2, kunye ne-S pole ye-rotor iya kujikeleza kwindawo ye-coil 5, njengoko kuboniswe kwi-Figure 6. Emva koko sisusa i-current ye-stator coils 2 kunye ne-5, kwaye emva koko sigqithise okwangoku kwi-stator coils 3 kunye ne-6. Ngeli xesha, iikhoyili ze-3 kunye ne-6 ziya kuvelisa intsimi yamagnetic, kwaye i-stator ilingana ne-bar magnet. , apho u-3 eyipali engu-S (esemazantsi) aze u-6 abe yipali engu-N (emantla). Ekubeni izibonda zamagnetic zesini esifanayo zikhanga omnye komnye, i-N pole ye-rotor iya kujikeleza kwindawo ye-coil 3, kunye ne-S pole ye-rotor iya kujikeleza kwindawo ye-coil 6, njengoko kuboniswe kwi-Figure 7. 
Ngendlela efanayo, i-current ye-stator coils 3 kunye ne-6 iyasuswa, kwaye okwangoku idluliselwe kwi-stator coils 4 kunye ne-1. Ngeli xesha, iikhoyili ze-4 kunye ne-1 ziya kuvelisa intsimi yamagnetic, kwaye i-stator ilingana. kwimagnethi yebar, apho isi-4 yipali ye-S (esemazantsi) kwaye isi-1 sisibonda esingu-N (emantla). Ekubeni izibonda zamagnetic zesini esifanayo zikhanga omnye komnye, i-N pole ye-rotor iya kujikeleza kwindawo ye-coil 4, kwaye i-S pole ye-rotor iya kujikeleza kwindawo ye-coil 1. Ukuza kuthi ga ngoku, injini ijikelezise isiqingatha sesangqa…. Isiqingatha sesibini isangqa siyafana nomgaqo wangaphambili, ngoko andiyi kuphinda apha.Singayiqonda ngokulula i-brushless DC motor njengokuloba ikherothi phambi kwedonki, ukuze idonki ihlale isiya ngakumnqathe. Ke, sinokugqithisela njani umsinga ochanekileyo kwiikhoyili ezahlukeneyo ngamaxesha ahlukeneyo? Oku kufuna isekethe yangoku yothutho…ayichazwanga apha. Ukuthelekiswa kwezinto eziluncedo kunye nezingeloncedo Imoto yebrashi ye-DC: isiqalo esikhawulezayo, ukunyathela ngexesha elifanelekileyo, ukulawulwa kwesantya esizinzile, ulawulo olulula, ubume obulula kunye nexabiso eliphantsi.Ingongoma kukuba itshiphu!ixabiso eliphantsi!ixabiso eliphantsi!Ngaphezu koko, inokuqala okukhulu ngoku, i-torque enkulu (amandla okujikeleza) ngesantya esiphantsi, kwaye inokuthwala umthwalo onzima. Nangona kunjalo, ngenxa yokungqubana phakathi kwebrashi yekhabhoni kunye necandelo labahambisi, i-DC brush motor ithanda ukuba neentlantsi, ubushushu, ingxolo, ukuphazamiseka kombane kwindawo yangaphandle, ukusebenza kakuhle okuphantsi kunye nobomi obufutshane.Ngenxa yokuba iibrashi zekhabhoni ziyinto esetyenziswayo, ziqhele ukusilela kwaye zifuna ukutshintshwa emva kwexesha elithile. Brushless DC motor: Ngenxa yokubabrushless DC motoriphelisa imfuneko yeebhrashi zekhabhoni, inengxolo ephantsi, akukho londolozo, izinga lokungaphumeleli eliphantsi, ubomi benkonzo ende, ixesha elisebenza ngokuzinzileyo kunye nombane, kunye nokuphazamiseka okuncinci kwezixhobo zerediyo. Kodwa kuyabiza! Iyabiza! Iyabiza! Iimpawu zesixhobo samandla Izixhobo zamandla zizixhobo ezisetyenziswa kakhulu ebomini. Kukho iibrendi ezininzi kunye nokhuphiswano oluqatha. Wonke umntu unomdla kakhulu kwixabiso.Kwaye izixhobo zamandla zifuna ukuthwala umthwalo onzima kwaye kufuneka zibe netorque enkulu yokuqalisa, efana nokubhobhoza ngesandla kunye nefuthe leempembelelo.Kungenjalo, xa kusonjwa, i-motor inokusilela ngokulula ukubaleka kuba i-drill bit ibambekile. Khawufane ucinge, i-brush ye-DC motor inexabiso eliphantsi, i-torque enkulu yokuqala, kwaye inokuthwala imithwalo enzima; nangona i-brushless motor inezinga eliphantsi lokungaphumeleli kunye nobomi obude, iyabiza, kwaye i-torque yokuqala ingaphantsi kakhulu kunemoto ebrashiweyo.Ukuba ubunikwe ukhetho, ungakhetha njani, ndicinga ukuba impendulo iyabonakala.
