Kubwerera kumbuyo kwa BLDC mota

Asanalowe m'madzi Mtengo wa BLDC mayankho, m'pofunika kumvetsa chifukwa chake mukuwafuna iwo.Ma motors a BLDC amatha kusinthidwa kukhala gawo limodzi, magawo awiri ndi magawo atatu; Kusintha kofala kwambiri ndi magawo atatu.Kuchuluka kwa magawo kumafanana ndi kuchuluka kwa ma stator windings, pomwe kuchuluka kwa mitengo yamaginito ya rotor kumatha kukhala nambala iliyonse malinga ndi ntchito. Popeza rotor ya BLDC motor imakhudzidwa ndi mizati yozungulira ya stator, malo a stator pole ayenera kutsatiridwa kuti ayendetse bwino magawo atatu a galimoto. magawo atatu agalimoto. Masitepe asanu ndi limodzi awa (kapena oyendetsa) amasuntha gawo lamagetsi, zomwe zimapangitsa kuti maginito okhazikika a rotor asunthire shaft yamoto.

Potengera katsatidwe kake kamayendedwe ka mota, wowongolera magalimoto amatha kugwiritsa ntchito siginecha yapamwamba kwambiri ya pulse wide modulation (PWM) kuti achepetse bwino mphamvu yamagetsi yomwe imayendetsedwa ndi mota motero kusintha liwiro la mota. kusinthasintha kwa kapangidwe kake pokhala ndi gwero limodzi lamagetsi lopezeka pama injini osiyanasiyana, ngakhale gwero lamagetsi la DC lili pamwamba kwambiri pamagetsi ovotera. kuikidwa pakati pa galimoto ndi wolamulira.Apa ndipamene njira zoyankhira ndizofunikira;Kuti mukhale ndi mphamvu yolondola ya galimotoyo, wolamulira ayenera kudziwa nthawi zonse malo enieni a stator ndi rotor.Kulakwika kulikonse kapena kusintha kwa gawo muzoyembekezereka komanso zenizeni. maudindo atha kubweretsa zinthu zosayembekezereka komanso kutsika kwa magwiridwe antchito. Pali njira zambiri zopezera ndemanga iyi pokhudzana ndi comm.kukhazikitsidwa kwa BLDC motere, koma chofala kwambiri ndikugwiritsa ntchito masensa a hall effect, encoders, kapena rotary transformers.Kuonjezera apo, mapulogalamu ena amadaliranso luso lamakono lamagetsi kuti akwaniritse mayankho.
