Ma mota amapezeka pafupifupi kulikonse. Bukuli likuthandizani kuphunzira zoyambira zama mota zamagetsi, mitundu yomwe ilipo komanso momwe mungasankhire mota yoyenera. Mafunso oyambira oti muyankhe posankha mota yoyenera kwambiri ndi mtundu womwe ndiyenera kusankha komanso zomwe ndizofunikira.
Kodi ma mota amagwira ntchito bwanji?
Injini yamagetsi yogwedezekantchito posintha mphamvu zamagetsi kukhala mphamvu yamakina kuti apange kuyenda. Mphamvu imapangidwa mkati mwa mota kudzera mu kulumikizana pakati pa mphamvu ya maginito ndi mphamvu yozungulira (AC) kapena mphamvu yolunjika (DC). Pamene mphamvu ya mphamvu yamagetsi ikuwonjezeka, mphamvu ya mphamvu ya maginito imawonjezekanso. Kumbukirani lamulo la Ohm (V = I*R) m'maganizo; mphamvu yamagetsi iyenera kuwonjezeka kuti isunge mphamvu yamagetsi yomweyi pamene kukana kukuwonjezeka.
Magalimoto Amagetsiali ndi ntchito zosiyanasiyana. Ntchito zachikhalidwe zamafakitale zimaphatikizapo ma blowers, makina ndi zida zamagetsi, mafani ndi mapampu. Anthu okonda zosangalatsa nthawi zambiri amagwiritsa ntchito mainjini m'magwiritsidwe ang'onoang'ono omwe amafuna kuyenda monga ma robotics kapena ma module okhala ndi mawilo.
Mitundu ya injini:
Pali mitundu yambiri ya ma DC motors, koma omwe amagwiritsidwa ntchito kwambiri ndi opukutidwa kapena opanda maburashi. Palinsoma mota ogwedezeka, ma stepper motors, ndi ma servo motors.
Ma mota a burashi a DC:
Ma mota a DC brush ndi amodzi mwa osavuta kwambiri ndipo amapezeka m'zida zambiri, zoseweretsa, ndi magalimoto. Amagwiritsa ntchito maburashi olumikizana omwe amalumikizana ndi commutator kuti asinthe momwe magetsi amayendera. Ndi otsika mtengo kupanga komanso osavuta kuwongolera ndipo ali ndi torque yabwino kwambiri pa liwiro lotsika (lomwe limayesedwa mu revolutions pa mphindi imodzi kapena RPM). Zoyipa zingapo ndi zakuti amafunika kukonzedwa nthawi zonse kuti asinthe maburashi otha ntchito, ali ndi liwiro lochepa chifukwa cha kutentha kwa maburashi, ndipo amatha kupanga phokoso lamagetsi kuchokera ku burashi.
Ma mota a DC opanda maburashi:
Injini yabwino kwambiri yogwedezekaMa mota a DC opanda brushless amagwiritsa ntchito maginito okhazikika mu rotor assembling yawo. Ndi otchuka pamsika wamasewera a ndege ndi magalimoto apansi. Ndi ogwira ntchito bwino, amafunika kukonza pang'ono, amapanga phokoso lochepa, ndipo ali ndi mphamvu zambiri kuposa ma mota a DC opangidwa ndi brushed. Amathanso kupangidwa mochuluka ndipo amafanana ndi mota ya AC yokhala ndi RPM yokhazikika, kupatulapo yoyendetsedwa ndi DC current. Komabe, pali zovuta zingapo, zomwe zikuphatikizapo kuti ndizovuta kuzilamulira popanda woyang'anira wapadera ndipo zimafuna katundu woyambira wotsika komanso ma gearbox apadera mu mapulogalamu oyendetsa zomwe zimapangitsa kuti azikhala ndi ndalama zambiri, zovuta, komanso zolepheretsa zachilengedwe.

Ma mota oyendera masitepe
Vibratin ya mota ya stepperg amagwiritsidwa ntchito pa ntchito zomwe zimafuna kugwedezeka monga mafoni am'manja kapena zowongolera masewera. Amapangidwa ndi mota yamagetsi ndipo ali ndi kulemera kosakwanira pa shaft yoyendetsera yomwe imayambitsa kugwedezeka. Angagwiritsidwenso ntchito m'ma buzzers osagwiritsa ntchito zamagetsi omwe amagwedezeka chifukwa cha phokoso kapena ma alarm kapena mabelu a zitseko.
Nthawi iliyonse mukafuna kuika bwino malo, ma stepper motors ndi anzanu. Amapezeka mu makina osindikizira, zida zamakina, ndi makina osindikizira.
Makina owongolera occess ndipo amapangidwira mphamvu yamagetsi yogwira ntchito yomwe imapatsa wogwiritsa ntchito mphamvu yosuntha kuchokera pa sitepe imodzi kupita ku ina. Ali ndi makina owongolera omwe amawonetsa malo kudzera mu ma pulse a chizindikiro omwe amatumizidwa kwa dalaivala, omwe amawamasulira ndikutumiza voteji yofanana ku injini. Ndi osavuta kupanga ndikuwongolera, koma amakoka mphamvu yayikulu nthawi zonse. Mtunda wa sitepe yaying'ono umachepetsa liwiro lalikulu ndipo masitepe amatha kudumpha akanyamula katundu wambiri.

Zoyenera kuganizira pogula injini:
Pali makhalidwe angapo omwe muyenera kuwaganizira bwino posankha mota koma mphamvu yamagetsi, mphamvu yamagetsi, mphamvu yamagetsi, ndi liwiro (RPM) ndizofunikira kwambiri.
Mphamvu yamagetsi ndiyo imapatsa mphamvu mota ndipo mphamvu yamagetsi yochuluka kwambiri imawononga mota. Pa ma DC motors, mphamvu yamagetsi yogwira ntchito ndi yokhazikika ndiyofunika. Mphamvu yamagetsi yogwira ntchito ndi kuchuluka kwa mphamvu yamagetsi komwe mota ikuyembekezeka kukoka pogwiritsa ntchito mphamvu yamagetsi yanthawi zonse. Mphamvu yamagetsi yokhazikika imagwiritsa ntchito mphamvu yamagetsi yokwanira kuti mota iziyenda pa liwiro la stall, kapena 0RPM. Iyi ndi mphamvu yamagetsi yayikulu yomwe mota iyenera kukoka, komanso mphamvu yayikulu ikachulukitsidwa ndi mphamvu yamagetsi yokhazikika. Ma heat sinks ndi ofunikira kwambiri kuyendetsa mota nthawi zonse kapena akuyendetsa pamlingo wapamwamba kuposa mphamvu yamagetsi yokhazikika kuti ma coil asasungunuke.
Voltage imagwiritsidwa ntchito kuti magetsi a net current ayende mbali imodzi ndikugonjetsa magetsi akumbuyo. Voltage ikakwera, mphamvu ya torque imakwera. Voltage rating ya mota ya DC imasonyeza mphamvu yamagetsi yogwira ntchito bwino kwambiri ikamagwira ntchito. Onetsetsani kuti mwagwiritsa ntchito voltage yoyenera. Ngati mugwiritsa ntchito ma volts ochepa, motayo sigwira ntchito, pomwe ma volts ambiri amatha kufupikitsa ma windings zomwe zimapangitsa kuti mphamvu itayike kapena kuwonongeka kwathunthu.
Mphamvu yogwiritsira ntchito ndi yokhazikika iyeneranso kuganiziridwa ndi mphamvu yokhazikika. Mphamvu yogwirira ntchito ndi kuchuluka kwa mphamvu yomwe injini idapangidwira kupereka ndipo mphamvu yokhazikika ndi kuchuluka kwa mphamvu yokhazikika yomwe imapangidwa mphamvu ikagwiritsidwa ntchito kuchokera ku liwiro la galimoto. Muyenera kuyang'ana nthawi zonse mphamvu yogwirira ntchito yofunikira, koma mapulogalamu ena amafunikira kuti mudziwe kutalika komwe mungakankhire injiniyo. Mwachitsanzo, ndi loboti yoyendetsedwa ndi mawilo, mphamvu yabwino imafanana ndi kuthamanga kwabwino koma muyenera kuwonetsetsa kuti mphamvu yokhazikika ndi yamphamvu mokwanira kukweza kulemera kwa loboti. Pankhaniyi, mphamvu ndi yofunika kwambiri kuposa liwiro.
Liwiro, kapena liwiro (RPM), lingakhale lovuta pankhani ya ma mota. Lamulo lalikulu ndilakuti ma mota amayenda bwino kwambiri pa liwiro lapamwamba koma nthawi zina sizingatheke ngati pakufunika kuyika ma gear. Kuwonjezera ma gear kumachepetsa kugwira ntchito kwa injini, choncho ganiziraninso liwiro ndi kuchepetsa mphamvu ya injini.
Izi ndi mfundo zofunika kuziganizira posankha mota. Ganizirani cholinga cha ntchito ndi mphamvu yomwe imagwiritsa ntchito posankha mtundu woyenera wa mota. Mafotokozedwe a ntchito monga magetsi, mphamvu, mphamvu, ndi liwiro ndi omwe adzatsimikizire kuti ndi mota iti yoyenera kwambiri kotero onetsetsani kuti mwayang'anira zofunikira zake.
Kampani ya Leader Microelectronics (Huizhou) Co., Ltd., yomwe idakhazikitsidwa mu 2007, ndi kampani yapadziko lonse lapansi yomwe imagwiritsa ntchito kafukufuku ndi chitukuko, kupanga ndi kugulitsa. Timapanga zinthu zambiri.mota yathyathyathya, mota yolunjika, mota yopanda burashi, mota yopanda coreless, mota ya SMD, mota yopangira ma Air, mota yochepetsera liwiro ndi zina zotero, komanso mota yaying'ono yomwe imagwiritsidwa ntchito m'magawo ambiri.
Lumikizanani nafe kuti mupeze mtengo wokwanira wa zinthu zomwe zapangidwa, zomwe zasinthidwa, komanso momwe zingagwirizanitsidwe.
