Kodi Magalimoto Opangira Ma Curtain Amagetsi Amagwira Ntchito Bwanji Ndipo Ndi Njira Ziti Zowongolera Liwiro Zomwe Angagwiritse Ntchito?

Kutsegula ndi kutseka kwa makatani amagetsi anzeru kumadalira kuzungulira kwa ma micro motors kuti akwaniritse. Ma motor ena amagetsi amagetsi amagwiritsa ntchito ma AC motors, koma chifukwa cha kupita patsogolo kwa ukadaulo, ma micro DC motors akhala akugwiritsidwa ntchito kwambiri pamitundu yosiyanasiyana ya zinthu zamagetsi. Ndiye, ubwino wa ma DC motors omwe amagwiritsidwa ntchito mu makatani amagetsi ndi wotani? Kodi njira zodziwika bwino zowongolera liwiro ndi ziti? Makatani amagetsi amagwiritsa ntchito ma micro DC motors okhala ndi zochepetsera magiya, zomwe zili ndi ubwino wa torque yayikulu komanso liwiro lotsika, ndipo zimatha kuyendetsa mitundu yosiyanasiyana ya makatani kutengera ma reduction ratios osiyanasiyana. Ma micro DC motors wamba mu makatani amagetsi ndi ma brushed motors ndi ma brushless motors. Ubwino waukulu wa ma DC motors opangidwa ndi brushed ndi monga torque yayikulu yoyambira, ntchito yosalala, mtengo wotsika, komanso kuwongolera liwiro kosavuta; ma DC motors opanda brushless ali ndi ubwino wokhala ndi moyo wautali komanso phokoso lotsika, koma mtengo wawo ndi wapamwamba, ndipo kuwongolera ndi kovuta kwambiri. Chifukwa chake, pali makatani ambiri amagetsi pamsika omwe amagwiritsa ntchito ma brushed motors.

Njira Zosiyanasiyana Zowongolera Liwiro la Ma Micro DC Motors mu Makatani Amagetsi

1. Liwiro la mota ya DC yamagetsi likasinthidwa mwa kuchepetsa mphamvu ya armature, dera la armature limafuna mphamvu ya DC yokhazikika, ndipo kukana kwa dera la armature ndi dera loyatsira ziyenera kukhala zochepa momwe zingathere. Mphamvu yamagetsi ikachepa, liwiro la mota ya DC yamagetsi lidzachepanso mofanana.

2. Kuwongolera liwiro pogwiritsa ntchito kukana kwa mndandanda mu dera la armature la mota ya DC, kukana kwa mndandanda kumakhala kwakukulu, mawonekedwe a makina amakhala ofooka, komanso liwiro limakhala losakhazikika. Pa liwiro lotsika, chifukwa cha kukana kwakukulu kwa mndandanda, mphamvu zambiri zimatayika, ndipo mphamvu imakhala yotsika. Mtundu wowongolera liwiro umakhudzidwa ndi katundu, ndiko kuti, katundu wosiyanasiyana umabweretsa zotsatira zosiyana zowongolera liwiro.

3. Kulamulira liwiro la maginito kofooka, kuti dera la maginito la mota ya DC yophimba magetsi lisadzazidwe kwambiri, woyang'anira liwiro ayenera kugwiritsa ntchito mphamvu ya maginito yofooka m'malo mwa mphamvu ya maginito yolimba. Mphamvu yamagetsi ya mota ya DC imasungidwa pamtengo wovotera, ndipo kukana kwa mndandanda mu dera la armature kumachepetsedwa. Mphamvu yamagetsi yotulutsa mpweya ndi mphamvu yamagetsi imachepetsedwa powonjezera mphamvu yamagetsi yotulutsa mpweya Rf, motero kumawonjezera liwiro la mota yamagetsi yophimba magetsi DC ndikufewetsa mawonekedwe a makina. Liwiro likakwera, ngati mphamvu yamagetsi ikadali pamtengo wovotera, mphamvu ya mota idzapitirira mphamvu yovotera, zomwe zimapangitsa kuti mota igwire ntchito mopitirira muyeso, zomwe siziloledwa. Chifukwa chake, liwiro lofooka la maginito likasinthidwa, mphamvu yamagetsi idzachepa mofanana ndi kuwonjezeka kwa liwiro la mota. Uku ndi kuwongolera liwiro lamagetsi kosalekeza. Kuti mupewe kuti rotor yozungulira ya mota isasweke ndikuwonongeka chifukwa cha mphamvu yambiri ya centrifugal, muyenera kusamala kuti musapitirire malire ololedwa a liwiro la mota ya DC mukagwiritsa ntchito mphamvu yofooka yamagetsi yozungulira.

4. Mu makina owongolera liwiro la mota ya DC yotchingira magetsi, njira yosavuta yomaliza kulamulira liwiro ndikusintha kukana mu dera la armature. Njira iyi ndi yosavuta komanso yotsika mtengo, ndipo ndi yothandiza kwambiri powongolera liwiro la makatani amagetsi.

Izi ndi makhalidwe ndi njira zowongolera liwiro la ma DC motors omwe amagwiritsidwa ntchito mu makatani amagetsi.
