Njengomthombo wamandla wezinto zikagesi noma imishini ehlukahlukene, umsebenzi obalulekile wemoto ukubangela i-torque yedrayivu.

Yize isinciphisi seplanethi sisetshenziswa ikakhulukazi ngokuhambisana nama-servo motors nama-stepper motors, ulwazi lochwepheshe lwamamotho lusathandwa kakhulu.Ngakho-ke, nganginesineke ukubona lesi “sifinyezo sokusebenza kwezimoto okunamandla emlandweni”.Buya ukuze wabelane nawo wonke umuntu.

I-Brushless Direct Current Motor (BLDCM) isusa ukushiyeka okungokwemvelo kwamamothoni e-DC abhulashiwe futhi imiselele ama-rotor angumshini ngezinsimbi ze-electronic motor rotor.Ngakho-ke, ama-motor wamanje aqondile angama-brushless anezici ezinhle kakhulu zejubane elihlukile nezinye izici zamamotho we-DC.Ibuye ibe nezinzuzo zesakhiwo esilula sokuxhumana kwe-AC motor, akukho ilangabi lokushintsha, ukusebenza okuthembekile nokugcinwa kalula.
Izimiso eziyisisekelo nama-algorithms okuthuthukisa.

Imithetho ye-BLDC yokulawula imoto ilawula indawo kanye nohlelo lwe-motor rotor ethuthukiswa yinjini ibe isilungisisi.Ngokukhwabanisa kwesilinganiso sokulawula okuvaliwe, kunemithetho emibili eyengeziwe, okungukuthi, ukulinganisa okunembile kwesivinini se-motor rotor/noma i-motor current kanye nesignali yayo ye-PWM yokulawula amandla okukhipha isilinganiso semoto.

I-BLDC motor ingakhetha ukulandelana kwezinhlangothi noma isikhungo sokuphatha ukuze ilandele isignali ye-PWM ngokuvumelana nemithetho yesicelo.Izinhlelo zokusebenza eziningi zishintsha kuphela ukusebenza kwangempela ngenani elishiwo, futhi amasiginali we-PWM wokulandelana onqenqemeni okungu-6 azokhethwa.Lokhu kubonisa ukulungiswa kwesikrini okuphezulu.Uma usebenzisa iseva yenethiwekhi eshiwo ukuze uthole indawo enembile, isistimu yokubhuleka edla amandla noma ukubuyisela emuva amandla okushayela, kutuswa kakhulu ukusebenzisa isikhungo sokuphatha esigcwalisiwe ukuze ulandelele isignali ye-PWM.

Ukuze kwenziwe ngcono ingxenye yerotha yemoto kazibuthe, injini ye-BLDC isebenzisa inzwa ye-Hall-effect ukukhombisa ukuma okuphelele kokungeniswa kukazibuthe.Lokhu kubangela izicelo ezengeziwe kanye nezindleko eziphakeme.Ukusebenza kwe-Inductorless BLDC kuqeda isidingo sezinto zeHholo, futhi kukhethwa kuphela amandla e-electromotive azidalayo (amandla e-electromotive) enjini ukuze abikezele futhi ahlaziye ingxenye ye-rotor yenjini.Ukusebenza okungenazinzwa kubaluleke kakhulu ezinhlelweni zokusebenza zokulawula isivinini esibiza kancane njengamafeni okupholisa namaphampu.Uma usebenzisa ama-motor e-BLDC, amafriji nama-compressor nawo kufanele asetshenziswe ngaphandle kwama-inductors.Ukufakwa nokugcwaliswa kwesikhathi esigcwele somthwalo
Amamotho amaningi e-BLDC awadingi i-PWM ehambisanayo, ukufakwa kwesikhathi sokulayisha okugcwele noma isinxephezelo sesikhathi sokulayisha esigcwele.Kungenzeka kakhulu ukuthi izinhlelo zokusebenza ze-BLDC ezinalesi sici zingamamotho asebenza kakhulu e-BLDC servo, ama-sine-wave akhuthazwayo e-BLDC motors, ama-brushed motors AC, noma ama-PC synchronous motors.

Kusetshenziswa izinhlelo eziningi ezihlukene zokulawula ukukhombisa ukukhohliswa kwamamotho e-BLDC.Imvamisa, i-transistor yamandla okukhiphayo isetshenziswa njengophakeli wamandla olawulwayo ukuze kusetshenziswe amandla kagesi enjini.Lolu hlobo lwendlela akulula ukulusebenzisa uma ushayela injini enamandla amakhulu.Amamotho anamandla amakhulu kufanele asetshenziswe yi-PWM, futhi i-microprocessor kufanele icaciswe ukuze ibonise imisebenzi yokuqala nokulawula.

Uhlelo lokulawula kufanele lubonise imisebenzi emithathu elandelayo:

I-voltage yokusebenza ye-PWM esetshenziselwa ukulawula isivinini semoto;

Isistimu esetshenziselwa ukushintsha injini ibe yi-rectifier;

Sebenzisa amandla okwenza i-electromotive noma i-Hall element ukuze ubikezele futhi uhlaziye indlela ye-motor rotor.

Ukulungiswa kobubanzi be-pulse kusetshenziselwa kuphela ukusebenzisa i-voltage yokusebenza eguquguqukayo kumawindi ahambayo.I-voltage esebenzayo enengqondo ihlotshaniswa kahle nomjikelezo womsebenzi we-PWM.Lapho kutholwa ukuguqulwa okufanele kwesilungisisi esilungisisayo, izici zesilinganiso setorque ze-BLDC ziyefana nalawa mamotho e-DC alandelayo.I-voltage yokusebenza eguquguqukayo ingasetshenziselwa ukuphatha isivinini kanye ne-torque eguquguqukayo yenjini.
