Kodi burashi ya DC imagwira ntchito bwanji?

A micro brush DC motor ndi mota wamba yomwe imagwiritsidwa ntchito pamagetsi, zoseweretsa, ndi zina zotero. Motor yaying'ono iyi imagwira ntchito pogwiritsa ntchito mfundo za electromagnetism. Ili ndi mphamvu yosinthira mphamvu zamagetsi kukhala mphamvu zamakina zapangitsa kuti ikhale chisankho chodziwika bwino pazogwiritsa ntchito zosiyanasiyana.

Mfundo Yogwirira Ntchito

- Mphamvu yamagetsi yamagetsi

Mfundo yoyendetsera ntchito ya amicro brush DCZimatengera kulumikizana pakati pa maginito a maginito awiri: rotor ndi stator. Rotor ndi maginito okhazikika, pomwe stator ndi maginito amagetsi okhala ndi koyilo ya waya. Mphamvu yamagetsi ikaperekedwa ku koyilo ya waya, imapanga mphamvu ya maginito. Mphamvu ya maginito iyi imalumikizana ndi maginito osatha a rotor, zomwe zimapangitsa kuti rotor ikhale yozungulira.

- Brush Commutator System

Dongosolo loyendetsa burashi limagwiritsidwa ntchito kuwonetsetsa kuti rotor ikupitilizabe kuzungulira bwino mbali imodzi. Makina osinthira maburashi amakhala ndi maburashi awiri achitsulo, omwe amagwiritsidwa ntchito kutumiza magetsi kuchokera pamagetsi osayima kupita kumagetsi ozungulira. The commutator ndi segmented cylindrical conductive rotor yolumikizidwa ndi shaft motor. Zimagwira ntchito potembenuza nthawi ndi nthawi polarity wapano wotumizidwa ku koyilo ya waya, yomwe imasintha maginito polarity ya rotor, ndikupangitsa kuti izizungulira mosalekeza mbali imodzi.

Mapulogalamu

Coin vibratoramagwiritsidwa ntchito m'mapulogalamu osiyanasiyana chifukwa chakuchita bwino kwambiri, kukula kwake kophatikizika, komanso kuthekera kowongolera bwino. Amapezeka muzinthu zingapo, kuphatikiza zoseweretsa, zida zamankhwala, zida zamagalimoto, ndi zamagetsi.

- Zoseweretsa: ma brush DC motors amagwiritsidwa ntchito pazoseweretsa zazing'ono monga magalimoto oyendetsedwa patali, mabwato, ndi maloboti.

- Zida Zachipatala: Zimagwira ntchito yofunika kwambiri pazida zamankhwala monga mapampu olowetsera makina a CPAP, ndi zowunikira magazi.

- Zamagetsi: Zimapezekanso mumagetsi ogula monga makamera, mafoni am'manja, ndi ma drones.

Mapeto

The micro brush DC motor ndi imodzi mwama motors omwe amagwiritsidwa ntchito kwambiri komanso amagwiritsidwa ntchito kwambiri chifukwa cha kuthekera kwake. Kukula kwake kophatikizika ndi kudalirika kumapangitsa kukhala chisankho chodziwika pamapulogalamu ambiri.
