1, Ndeapi marudzi emamota madiki estepper? Ndezvipi hunhu hwawo?
Yakakamurwa muzvikamu zvitatu zvichienderana nechimiro cherotor. Rudzi rwePM (permanent magnet type) rune chimiro chiri nyore, mutengo wakaderera, uye step angle inowanzo kuve 7.5 ° kana 15 °. Rune torque diki uye rwakakodzera mashandisirwo akadai semaprinta nemakamera gimbals asingade kunyatsojeka; VR type (variable resistance) rotors dzakagadzirwa nezvinhu zvemagineti zvakapfava zvine resolution yakaderera (inenge hafu yeHB type) uye hunhu husina kunaka hwe transient, uye ikozvino hadzichanyanyi kushandiswa; HB type (hybrid) inosanganisa zvakanakira zviviri zvekutanga, ne common step angle ye1.8 ° kana 0.9 °, high torque, uye high resolution, zvichiita kuti ive sarudzo huru yemidziyo ye micro precision.
2, Chii chinonzi kururama kwekona yedanho remota diki yestepper? Zvikanganiso zvichaungana here?
Kururama kwemota ye general stepper mota ndeye 3% kusvika 5% ye step angle uye haiunganidzi. Izvi zvinoreva kuti kunyangwe mushure mekushanda kakawanda, zvikanganiso zvedanho rega rega hazviunganidzike kusvika panzvimbo yekupedzisira. Kururama kwakajairika kwemota ye hybrid micro stepper ine zvikamu zviviri kunogona kusvika 0.18 ° (ye step angle ye 1.8 °).
3, mota ye stepper miniature inogona kuburitsa torque yakawanda sei?
Hurefu hwescope hwakakura zvikuru. Torque inobata saizi dzebase yemuchina iri pasi pe20mm yerudzi rwePM inogona kunge iri 0.02N · m; NEMA 8~NEMA 11 (20mm~28mm) inowanzo tangira pa0.03~0.1N · m; NEMA 14~NEMA 17 (35mm~42mm) inogona kusvika pa0.2~0.5N · m. Kupfuura 0.8N · m kunowanzo da base yeNEMA 17 kana kupfuura, iyo inopfuura chikamu che "micro".
4, Sei torque yemota yestepper ichidzikira sezvo kumhanya kuchiwedzera?
Kana ichitenderera, winding inductance inogadzira reverse electromotive force, uye kana frequency yakakwira, reverse electromotive force inowedzera, zvichikonzera kudzikira kwephase current uye output torque. Micro motors dzine winding turns shoma uye inductance yakaderera, izvo zvinoita kuti mhedzisiro iyi ionekwe zvakanyanya pakumhanya kwakanyanya.
5, Ko mota dze micro stepper dzinogona kushandiswa here pakufamba kwemutsetse?
Ehe. Mota yemagetsi inopinza sikuruu murotor uye inoburitsa zvakananga kufamba kwemagetsi, zvichibvisa kudiwa kwenzira dzekutumira zvinhu kunze. Kufamba kwemota dzemagetsi dzinopinza dzinowanzova pakati pe10mm ~ 200mm, ne 0.5N ~ 10N. Dzinowanzo shandiswa mumapombi emagetsi, mapombi emagetsi, uye michina yekuvhiya midiki.
6, Ndeapi ma parameter anotanga kutsanangurwa pakusarudza mota ye micro stepper?
Kutanga, sarudza torque yemutoro nenzvimbo yekuisa. Torque yekubatirira inofanira kunge yakakura kupfuura torque chaiyo yemutoro nekatatu. Tichifunga kuti ma micro motors anonyanya kunzwa zvakanyanya kana akawandisa, zvinokurudzirwa kutora safety factor ye1.4 kusvika ku2. Panguva imwe chete uchisimbisa nzvimbo yekuisa iripo, saizi inowanzova chinhu chekutanga chinodzivisa mumidziyo midiki.
7, Ndeupi musiyano uripo pakati pekuchengetedza torque ne dynamic torque?
Kuchengetedza torque ndiyo torque yepamusoro iyo mota inogona kuchengetedza ne rated current kana yakamira, zvichiratidza kugona kwayo kusingachinji. Dynamic torque ndiyo torque chaiyo inobuda panguva yekushanda, iyo inoenderana neavhareji yemagetsi panguva yekushanda uye inoderera nekumhanya kuri kuwedzera. Pakusarudza, hatingofaniri kungotarisa pakuchengetedza torque chete, tinofanira kutarisa kune torque characteristic frequency curve.
8, Ungasarudza sei saizi yehwaro zvichibva pa torque?
Ruzivo rweruzivo: NEMA 8~NEMA 17 inogona kusarudzwa pasi pe 0.8N · m; Pasi pe 0.1N · m, NEMA 8~NEMA 11 inowanzo kukwana. Muzviitiko zve micro application, torque inoda kazhinji iri mukati me 0.5N · m, neNEMA 14~NEMA 17 iriyo nzvimbo huru.
9, Unganzwisisa sei ratio yemagetsi emota ye stepper miniature?
Mwenje wekutyaira (phase current) ndiwo muganho wemagetsi pamativi ese emupendero wechikamu chimwe chete, uye hausi muganho wakakwana. Unogona kugadziriswa zvichienderana nemutengo wakarongwa zvichienderana nemamiriro chaiwo ekushanda, asi kudarika mutengo wakarongwa kunowedzera kupisa, uye pasi pemutengo wakarongwa kuchaita kuti pave netorque isina kukwana. Kuramba kutenderera kwema micro motors kwakanyanya, uye simba rekutyaira rakajairika riri pakati pe0.2 ~ 1.5A.
10, Kufananidza inertia kwakakosha here pakusarudza mota dze micro stepper?
Zvakakosha zvikuru. Chiyero chekusashanda zvakanaka kwemutoro kune kusingashande zvakanaka kwemota chakanyanya kukwira, izvo zvinogona kukonzera kusashanda zvakanaka uye kurasikirwa nyore nyore panguva yekumhanyisa. Kusashanda zvakanaka kwerotor yemota diki pachayo kudiki kwazvo, asi kusashanda zvakanaka kwemutoro (senge sikuruu nekubatanidza) kunogona kunge kwakakura kupfuura kwemota pachayo, saka inofanira kuverengerwa pakusarudza.
