Ntchito mfundo ya brushed magetsi kubowola

The HammerKutalika kwa 28MMKapangidwe kake ka kubowola kwamagetsi kopukutidwa ndi maburashi a stator + rotor +, omwe amapeza torque yozungulira kudzera pamaginito ozungulira, potero amatulutsa mphamvu ya kinetic.Burashi ndi commutator zimagwirizana nthawi zonse ndi kukangana, ndipo zimagwira ntchito ya conduction ndi kusinthasintha panthawi yozungulira.

Kubowola kwamagetsi kumatengera kusintha kwamakina, mtengo wa maginito susuntha, ndipo koyilo imazungulira.Kubowola kwamagetsi kukagwira ntchito, koyilo ndi kozungulira zimazungulira, koma chitsulo cha maginito ndi burashi ya kaboni sizizungulira.Mayendedwe amakono a koyilo amasinthidwa ndi inverter ndi burashi yamagetsi yomwe imazungulira ndi kubowola kwamagetsi.

Pochita izi, malekezero awiri amphamvu a koyilo amakonzedwa mozungulira, olekanitsidwa ndi zida zotchingira kuti apange silinda, yomwe imalumikizidwa ndi shaft yobowola magetsi.Mphamvu zamagetsi zimapangidwa ndi zinthu ziwiri za carbon.Zipilala zing'onozing'ono (maburashi a kaboni), pansi pa kukanikiza kwa masika, kanikizani mfundo ziwiri pa silinda ya mphete ya koyilo yamphamvu kuchokera m'malo awiri okhazikika kuti mupatse mphamvu koyilo.

Pamene kubowola magetsi azungulira, koyilo osiyana kapena mizati iwiri ya koyilo yemweyo ndi mphamvu pa nthawi zosiyanasiyana, kuti NS mzati wa koyilo kupanga maginito ndi NS mzati wa wapafupi okhazikika maginito stator ndi oyenera ngodya kusiyana., Pangani mphamvu kukankhira kubowola magetsi kuzungulira.Mpweya wa carbon electrode umayenda pa coil terminal, ngati burashi pamwamba pa chinthucho, choncho amatchedwa carbon "brush".

Zomwe zimatchedwa "maburashi opambana, kulephera kumakhalanso maburashi."Chifukwa cha kutsetsereka kwapawiri, maburashi a kaboni amapakidwa, kupangitsa kutaya.Kutsegula ndi kuchotsa maburashi a kaboni ndi ma coil terminals adzasinthana, ndipo kuphulika kwa magetsi kudzachitika, kusweka kwa ma elekitiromatiki, ndipo zida zamagetsi zidzasokonekera.Kuphatikiza apo, chifukwa cha kutsetsereka kosalekeza ndi kukangana, maburashiwo amakhala a nthawi zonse kuvala ndi kung'ambika ndizomwe zimachititsanso kubowola burashi kwakanthawi kochepa.

Burashi ikawonongeka, iyenera kukonzedwa, koma kodi kudzakhala kovuta kuikonzanso mobwerezabwereza?M'malo mwake, sizingatero, koma sizingakhale bwino ngati pali kubowola kwamagetsi komwe sikufunikira kusintha burashi?Uku ndiye kubowola brushless.

Ntchito mfundo ya brushless kubowola magetsi

Kubowola kwamagetsi kopanda maburashi, monga dzina likunenera, ndi kubowola kwamagetsi kopanda burashi yamagetsi.Tsopano popeza palibe burashi yamagetsi, kodi kubowola kwamagetsi kungapitirire bwanji?

Zikuwonekeratu kuti kapangidwe ka kubowola kwamagetsi kopanda brushless ndi kosiyana ndendende ndi kabowola kamagetsi ka brushless:

Mu kubowola kwamagetsi kwa brushless, ntchito yosinthira imamalizidwa ndi dera lowongolera mu wowongolera (nthawi zambiri Hall sensor + controller, ukadaulo wapamwamba kwambiri ndi maginito encoder).

Kubowola kwamagetsi kopukutidwa kumakhala ndi mtengo wokhazikika wa maginito ndipo koyilo imatembenuka;kubowola kwamagetsi kwa brushless kumakhala ndi koyilo yokhazikika ndipo maginito amatembenuka.Mu kubowola kwamagetsi kwa brushless, sensor ya Hall imagwiritsidwa ntchito kuzindikira malo a maginito a maginito a maginito okhazikika, ndiyeno malinga ndi lingaliro ili, dera lamagetsi limagwiritsidwa ntchito kusinthira komwe kuli komweko mu koyiloyo panthawi yoyenera. kuonetsetsa kuti mphamvu ya maginito yolondola imapangidwira kuyendetsa kubowola kwamagetsi.Kuthetsa zophophonya ma brushed magetsi kubowola.

Mabwalo awa ndi omwe amawongolera mabowo amagetsi opanda brushless.Atha kugwiritsanso ntchito zina zomwe sizingachitike pobowola magetsi opukutidwa, monga kusintha ngodya yosinthira mphamvu, kubowola magetsi, kupanga kubowola kwamagetsi, kutseka kubowola kwamagetsi, ndikugwiritsa ntchito siginecha ya brake kuti asiye kuyatsa kubowola kwamagetsi. ..Chotsekera chamagetsi chamagetsi chagalimoto ya batri tsopano chimagwiritsa ntchito izi mokwanira.
