Ma motors amapezeka pafupifupi kulikonse. Bukuli likuthandizani kuti muphunzire zoyambira zamagalimoto amagetsi, mitundu yomwe ilipo komanso momwe mungasankhire mota yoyenera. Mafunso oyambira omwe ndiyenera kuyankha ndikusankha injini yoyenera kwambiri pakugwiritsa ntchito ndi mtundu wanji womwe ndiyenera kusankha komanso zomwe zili zofunika.
Kodi ma motors amagwira ntchito bwanji?
Kugwedezeka kwa mota yamagetsigwirani ntchito potembenuza mphamvu zamagetsi kukhala mphamvu zamakina kuti mupange kuyenda. Mphamvu imapangidwa mkati mwa mota kudzera mu mgwirizano pakati pa mphamvu ya maginito ndi maginito alternating (AC) kapena mwachindunji (DC) yapano. Pamene mphamvu ya panopa ikuwonjezeka chomwechonso mphamvu ya maginito. Sungani lamulo la Ohm (V = I * R) m'maganizo; mphamvu yamagetsi iyenera kuwonjezeka kuti ikhalebe yofanana ndi momwe kukana kumakulirakulira.
Magetsi Motorsndi mndandanda wa ntchito. Zomwe zimagwiritsidwa ntchito m'mafakitale zimaphatikizapo zowombera, makina ndi zida zamagetsi, mafani ndi mapampu. Ochita masewera olimbitsa thupi nthawi zambiri amagwiritsa ntchito ma mota muzinthu zing'onozing'ono zomwe zimafuna kusuntha monga ma robotic kapena ma module okhala ndi mawilo.
Mitundu yama injini:
Pali mitundu yambiri ya ma mota a DC, koma odziwika kwambiri ndi opukutidwa kapena opanda brush. Palinsoma injini akunjenjemera, ma stepper motors, ndi ma servo motors.
DC brush motors:
DC brush motors ndi imodzi mwazosavuta kwambiri ndipo imapezeka muzinthu zambiri, zoseweretsa, ndi magalimoto. Amagwiritsa ntchito maburashi olumikizana omwe amalumikizana ndi commutator kuti asinthe komwe akupita. Ndiotsika mtengo kupanga komanso osavuta kuwongolera komanso amakhala ndi torque yabwino kwambiri pa liwiro lotsika (lomwe limayezedwa mosintha pamphindi kapena RPM). Zoyipa zochepa ndizakuti zimafunika kukonza nthawi zonse kuti zisinthe maburashi otopa, kuthamanga pang'ono chifukwa cha kutentha kwa maburashi, ndipo kumatha kutulutsa phokoso lamagetsi kuchokera ku maburashi.
Brushless DC motors:
Makina abwino kwambiri onjenjemeraa brushless DC motors amagwiritsa ntchito maginito okhazikika pagulu lawo la rotor. Ndiwotchuka pamsika wokonda ndege ndi magalimoto apansi. Zimagwira ntchito bwino, zimafuna kusamalidwa pang'ono, zimapanga phokoso lochepa, ndipo zimakhala ndi mphamvu zambiri kuposa ma motors a DC opangidwa ndi brushed. Atha kupangidwanso mochuluka ndikufanana ndi mota ya AC yokhala ndi RPM yosalekeza, kupatula yoyendetsedwa ndi DC yapano. Pali zovuta zingapo, zomwe zimaphatikizapo kuti zimakhala zovuta kuziwongolera popanda wowongolera mwapadera ndipo zimafunikira zonyamula zotsika komanso ma gearbox apadera pamagalimoto oyendetsa zomwe zimawapangitsa kukhala ndi mtengo wapamwamba, zovuta, komanso malire a chilengedwe.

Stepper motors
Stepper motor vibrating amagwiritsidwa ntchito pamapulogalamu omwe amafunikira kugwedezeka monga mafoni am'manja kapena zowongolera masewera. Amapangidwa ndi mota yamagetsi ndipo amakhala ndi misa yosagwirizana pa shaft yoyendetsa yomwe imayambitsa kugwedezeka. Atha kugwiritsidwanso ntchito m'mabaza omwe si a pakompyuta omwe amanjenjemera ndi cholinga cha mawu kapena ma alarm kapena mabelu a pakhomo.
Nthawi zonse mukayika bwino, ma stepper motors ndi anzanu. Amapezeka mu osindikiza, zida zamakina, ndi pr
machitidwe olamulira ocess ndipo amapangidwira torque yogwira kwambiri yomwe imapatsa wogwiritsa ntchito mphamvu yosuntha kuchoka ku sitepe imodzi kupita ku ina. Ali ndi makina owongolera omwe amawonetsa malowo kudzera pamagetsi amawu omwe amatumizidwa kwa dalaivala, omwe amawatanthauzira ndikutumiza ma voliyumu olingana ndi injini. Ndiosavuta kupanga ndikuwongolera, koma amajambula pakali pano mosalekeza. Mayendedwe ang'onoang'ono amaletsa liwiro lapamwamba ndipo masitepe amatha kudumphidwa ponyamula katundu wambiri.

Zomwe muyenera kuziganizira pogula mota:
Pali zinthu zingapo zomwe muyenera kuziganizira posankha mota koma magetsi, ma torque, torque, ndi liwiro (RPM) ndizofunikira kwambiri.
Panopa ndizomwe zimapatsa mphamvu injini komanso kuchuluka kwamagetsi kumawononga mota. Kwa ma motors a DC, kugwira ntchito ndi ma stall current ndikofunikira. Kugwira ntchito ndi kuchuluka kwanthawi zonse komwe injini ikuyembekezeka kukokera pansi pa torque wamba. Pakali pano pamakhala torque yokwanira kuti mota iziyenda mwachangu, kapena 0RPM. Uwu ndiye kuchuluka kwamagetsi komwe injini imayenera kujambula, komanso mphamvu yayikulu ikachulukitsidwa ndi voliyumu yovotera. Kuzama kwa kutentha ndikofunikira nthawi zonse kumayendetsa mota kapena kuiyendetsa mokwera kuposa ma voliyumu omwe adavotera kuti ma koyilo asasungunuke.
Voltage imagwiritsidwa ntchito kuti ma neti aziyenda mbali imodzi ndikuwongolera mphamvu yakumbuyo. Kukwera kwamagetsi, kumapangitsanso torque. Ma voliyumu amagetsi a DC amawonetsa mphamvu yamagetsi yomwe imagwira ntchito bwino mukamagwira ntchito. Onetsetsani kuti mukugwiritsa ntchito voteji yoyenera. Ngati mumagwiritsa ntchito ma volts ochepa kwambiri, injiniyo sigwira ntchito, pomwe ma volts ambiri amatha kukhala ndi ma windings afupiafupi omwe amachititsa kuti magetsi awonongeke kapena kuwonongeka kwathunthu.
Makhalidwe ogwiritsira ntchito komanso osungira amafunikanso kuganiziridwa ndi torque. Makokedwe ogwiritsira ntchito ndi kuchuluka kwa torque yomwe injini idapangidwa kuti ipereke ndipo torque yolowera ndi kuchuluka kwa torque yomwe imapangidwa mphamvu ikagwiritsidwa ntchito kuchokera pa liwiro la khola. Nthawi zonse muyenera kuyang'ana torque yofunikira, koma ntchito zina zimafuna kuti mudziwe kutalika komwe mungakankhire mota. Mwachitsanzo, ndi loboti yamawilo, torque yabwino imafanana ndi kuthamanga kwabwino koma muyenera kuwonetsetsa kuti torque yogulitsirayo ndiyolimba mokwanira kuti ikweze kulemera kwa loboti. Munthawi imeneyi, torque ndiyofunikira kwambiri kuposa liwiro.
Kuthamanga, kapena liwiro (RPM), kumatha kukhala kovuta pankhani yama mota. Lamulo lambiri ndiloti ma motors amathamanga kwambiri pa liwiro lapamwamba kwambiri koma sizingatheke nthawi zonse ngati gearing ikufunika. Kuonjezera magiya kumachepetsa mphamvu ya injini, choncho ganiziraninso kuthamanga komanso kuchepetsa torque.
Izi ndi zofunika kuziganizira posankha mota. Ganizirani cholinga cha pulogalamuyo komanso momwe imagwiritsa ntchito posankha injini yoyenera. Mafotokozedwe a pulogalamu monga ma voliyumu, ma torque, ma torque, ndi liwiro zimatsimikizira kuti ndi injini iti yomwe ili yoyenera kwambiri chifukwa chake onetsetsani kuti mwalabadira zofunikira zake.
Yakhazikitsidwa mu 2007, Leader Microelectronics (Huizhou) Co., Ltd. ndi bizinesi yapadziko lonse lapansi yophatikiza R & D, kupanga ndi kugulitsa. Ife makamaka kubalagalimoto yamoto, injini ya mzere, brushless mota, motere wopanda maziko, SMD motor, Air-model motor, deceleration motor ndi zina zotero, komanso yaying'ono motor mu multifield application.
Lumikizanani nafe kuti mupeze ndalama zopangira kuchuluka, makonda ndi kuphatikiza.
