Kusankha pakati pa servo motor ndi motor stepper kungakhale kovuta kwambiri pokhudzana ndi kuyanjana kwa zinthu zingapo zopangidwa. Kuganizira ndalama, kuthamanga, kuthamanga, kuthamanga, ndi magalimoto oyendetsa magalimoto onse amachitapo kanthu pakusankha wopambana kwambiri pamagetsi anu.
Kusiyana kwakukulu pakati pa Stepper ndi Servo Motors
Mapuloteni ndi servo motors amasiyana m'njira ziwiri zofunika, pomangamanga awo ndi momwe amalamulira. Mitengo ya stepper imakhala ndi mitengo yambiri, maginito awiri a kumpoto ndi kummwera omwe amapangidwa ndi maginito osatha kapena magetsi, makamaka mitengo ya 50 mpaka 100. Poyerekezera, servo motors ali ndi mitengo yochepa, nthawi zambiri 4 mpaka 12 muyeso. Mthunzi uliwonse umapereka chilengedwe choyima kwa shaft motor. Mitengo yambiri imalola nthumwi yopuma kuti ipite molondola komanso moyenera pakati pa mtengo uliwonse ndipo imalola kuti stepper iwonetsedwe popanda ndemanga yowonjezera pazinthu zambiri. Ma servo motors nthawi zambiri amafuna malo osungira malo kuti azindikire malo a galimoto, makamaka ngati kayendetsedwe ka kayendedwe kamene kali kofunikira.
Kuyendetsa galimoto yopita ku malo enieni ndi kophweka kusiyana ndi kuyendetsa galimoto ya servo. Pogwiritsa ntchito makina oyendetsa galimoto, galimoto imodzi yokha imayendetsa galimoto imodzi pang'onopang'ono, kuyambira pamtengo umodzi mpaka kumtsinje. Popeza kukula kwake kwa motolo wapatsidwa kumayendetsedwa ndi kayendedwe kake, kusunthira kumalo enieni ndi nkhani yotumiza nambala yolondola ya magalimoto. Mosiyana ndi servo motors amawerengera kusiyana pakati pa malo omwe alipo kale ndi malo omwe adalamulidwa nawo ndipo panopa akufunikira kupita kumalo abwino. Ndi makompyuta amakono a makompyuta, magalimoto othamanga ndi ovuta kwambiri kulamulira kuposa servo motors.
Zopindulitsa
Mitengo ya stepper imapereka ubwino wambiri pa servo motors kupitirira miyeso yambiri ndikusavuta kuyendetsa galimoto. Mapangidwe a galimoto yothamanga amapereka mkondo wogwirizira nthawi zonse popanda kufunikira kuti galimoto iperekedwe. Mphuno ya stepper mothamanga kwambiri ndi yayikulu kuposa servo motor yofanana. Imodzi mwa ubwino waukulu kwambiri wa magalimoto oyendetsa ndizofika mtengo wotsika komanso kupezeka.
Zizindikiro za Servo
Pogwiritsa ntchito maulendo othamanga ndi othamanga kwambiri, servo motors amawala. Mitengo ya stepper imayenda mofulumira kwambiri pa 2,000 RPM, pamene servo motors imapezeka nthawi zambiri mofulumira. Servo motors amachititsanso kuti maulendo awo azikhala othamanga kwambiri, mpaka 90 peresenti ya pulogalamu yamtunduwu imapezeka kuchokera ku servo mwamsanga. Servo motors ndi opambana kwambiri kuposa ma motolo oyendetsa bwino omwe amakhala pakati pa 80-90%. Msewu wa servo ukhoza kupereka kawiri kawiri kavoti yawo yovotera kwa nthawi yochepa, kupereka chitsime cha mphamvu chokoka kuchokera pakufunika. Kuwonjezera apo, servo motors ali ndithu, amapezeka mu AC ndi DC pagalimoto, ndipo musadandaule kapena kuvutika ndi mavuto a resonance.
Kulephera Kwambiri
Chifukwa cha ubwino wawo wonse, magalimoto othamanga ali ndi zochepa zochepa zomwe zingayambitse kusokoneza ndi kugwiritsira ntchito malingana ndi momwe mukugwiritsira ntchito. Stepper motors alibe mphamvu iliyonse yosungira. Ndipotu, magalimoto oyendetsa galimoto amataya nthawi yambiri yamtundu wawo pamene amayandikira kwambiri paulendo wawo woyendetsa galimoto. Kutaya kwa 80 peresenti ya torque yovomerezeka pa 90% ya msinkhu wothamanga kwambiri. Mitambo ya stepper siyenso ngati servo motors pakufulumizitsa katundu. Kuyesera kufulumizitsa mofulumira mofulumira kumene stepper sangathe kupanga nthawi yokwanira kuti isamuke ku sitepe yotsatira musanayambe galimoto yoyendetsa galimoto kudzapangitsa kutsika kwake ndi kutayika. Ngati kulondola kwapadera kuli kofunika, kaya katundu pa motor sakuyenera kudutsa pajambuzi yake kapena stepper ayenera kuphatikizidwa pamodzi ndi malo osungirako malo kuti atsimikizidwe molondola. Mitima ya stepper imakhudzidwa ndi mavuto ozunguliridwa komanso osokonezeka. Pakapita mwamsanga, pang'onopang'ono malingana ndi katundu wolemera, galimoto yoyendetsa galimoto ingalowe mkati ndipo silingathe kuyendetsa katunduyo.
Izi zimapangitsa kuti asatengeke, kuyendetsa motors, kuthamanga kwambiri ndi phokoso.
Zitetezo za Servo
Servo motors amatha kupatsa mphamvu zambiri kuposa magalimoto oyendetsa, koma amafuna zovuta zambiri zoyendetsa magalimoto oyendetsa magalimoto ndi zochitika zapadera kuti zikhale bwino. Servo motors ndi okwera mtengo kwambiri kuposa ma motolo oyendetsa ndipo nthawi zambiri zimakhala zovuta kupeza. Ma servo motors nthawi zambiri amafuna bokosi zamagetsi, makamaka pafupipafupi opaleshoni. Chofunika cha bokosi la gear ndi malo otsegula maofesi amachititsa kuti servo yamapangizo apangidwe kwambiri ikhale yovuta komanso yowonjezera zosamalidwa zomwe zimapangidwira. Pamwamba pake, servo motors ndi okwera mtengo kwambiri kusiyana ndi stepper motors asanawonjezere mtengo wa malo encoder.
Chidule
Kusankha njira yabwino kwambiri yogwiritsira ntchito pulogalamu yanu kumadalira zofunikira zapangidwe zamakono za dongosolo lanu kuphatikizapo mtengo, zofunikira zenizeni, zofunikira za torque, kupezeka kwa magalimoto, ndi kufunika kwachangu. Zonsezi, servo motors ndi yabwino kwambiri paulendo wautali, mawotchi apamwamba pamene ma motchi amawotchera bwino mofulumizitsa kupititsa patsogolo, kugwiritsa ntchito maulendo apamwamba.
