Linear stepper mota, inozivikanwawo selinear stepper mota, ndeye magineti rotor musimboti nekudyidzana neiyo pulsed electromagnetic munda inogadzirwa ne stator kugadzira kutenderera, linear stepper mota mukati memotor kushandura inotenderera kuita mutsara kufamba. Linear stepper motors inogona kuita mutsara inofamba kana mutsara unodzosera mafambiro zvakananga. Kana mota inotenderera ichishandiswa sesimba sosi yekushandura kuita mutsara wekufamba, magiya, zvimiro zvecam uye michina yakaita semabhandi kana waya inodiwa. Yekutanga sumo ye linear stepper motors yaive muna 1968, uye inotevera nhamba inoratidza mamwe akajairwa mutsara stepper mota.
Basic musimboti wekunze anotyairwa linear motors
Iyo rotor yekunze inofambiswa mutsara stepper mota ndeye isingaperi magineti. Kana ikozvino ichiyerera kuburikidza ne stator winding, iyo stator winding inogadzira vector magnetic field. Iyi magnetic field inotyaira rotor kuti itenderere pane imwe kona, kuitira kuti kutungamira kwemagineti maviri e rotor ienderane nekutungamira kwe stator's magnetic field. Apo stator's vector magnetic field inotenderera nekona. Iyo rotor zvakare inotenderera pakona neiyi magnetic field. Pane imwe neimwe yemagetsi pulse input, rotor yemagetsi inotenderera nekona imwe uye inofamba nhanho imwe mberi. Inoburitsa angular displacement yakaenzana nenhamba ye pulses input uye spidhi inoenderana ne pulse frequency. Kuchinja kurongeka kwekuita mhepo simba kunodzosera kumashure mota. Saka iyo stepper mota inotenderera inogona kudzorwa nekudzora huwandu hwemapulses, frequency uye kurongeka kwekupa simba mamhepo emota yechikamu chimwe nechimwe.
Iyo mota inoshandisa screw seakisi inobuda, uye yekunze dhiraivha nati inobatwa nescrew kunze kwemota, ichitora imwe nzira yekudzivirira iyo screw nut kubva kutendeukira kuhama kune imwe neimwe, nokudaro ichiwana mutsara kufamba. Mhedzisiro iyi dhizaini yakareruka inobvumira kushandiswa kwemutsara stepper motors yakananga kune chaiyo mutsara mafambiro mune akawanda maapplication pasina kuisirwa yekunze mechanika yekubatanidza.
Zvakanakira zvekunze zvinotyairwa linear motors
Precision linear screw stepper motors inogona kutsiva masilinda mukatimamwe maapplication, kuwana mabhenefiti akadai sekumisikidza chaiko, kukurumidza kudzoreka, uye nekururama kwepamusoro. Linear screw stepper motors anoshandiswa mumhando dzakasiyana dzemashandisirwo anosanganisira kugadzira, kunyatso calibration, kuyerwa kwemvura kuyera, chaiko kufamba kwechinzvimbo, uye dzimwe nzvimbo dzakawanda dzine yakanyanya kurongeka zvinodiwa.
▲Kururamisa kwepamusoro, kudzokororwa kwekuisa chinzvimbo kusvika ± 0.01mm
Linear screw stepping mota inoderedza dambudziko re interpolation lag nekuda kweiyo yakapusa yekufambisa masisitimu, kurongeka kwechokwadi, kudzokorora uye kurongeka chaiko.Zviri nyore kuwana pane "rotary mota + screw". Iko kudzokororwa kwekumisikidza kurongeka kweyakajairwa screw ye linear screw stepping mota inogona kusvika ± 0.05mm, uye iyo yekudzokorora chinzvimbo cheiyo screw yebhora inogona kusvika ± 0.01mm.
▲ Kumhanya kwepamusoro, kusvika ku300m/min
Iko kumhanya kwemutsetse screw stepping mota ndeye 300m/min uye kukurumidza kuita 10g, ukuwo kumhanya kwebhora sikuruu iri 120m/min uye kukurumidza kuita 1.5g. Uye kumhanya kweiyo linear screw stepping mota inozovandudzwa mushure mekubudirira kugadzirisa dambudziko rekupisa, nepo "rotary The speed of "servo motor & ball screw" inogumira mukumhanya, asi zvakaoma kuvandudza zvimwe.
Hupenyu hwepamusoro uye kugadzirisa kuri nyore
Iyo linear screw stepping mota inokodzera kurongeka kwepamusoro nekuti hapana kubatana pakati pezvikamu zvinofamba uye zvikamu zvakagadziriswa nekuda kwegepu rekukwira uye kusapfeka nekuda kwekumhanya kwakanyanya kudzoreredza kufamba kwevanofambisa. Iyo bhora screw haigone kuvimbisa kurongeka kweiyo-yepamusoro-kumhanya kudzoreredza kufamba, uye kukurumidza-kumhanyisa kukweshera kunokonzeresa kupera kwe screw nut, izvo zvinokanganisa kurongeka kwekufamba uye hazvigone kuzadzisa kudiwa kwepamusoro-chaizvo.
Kusarudzwa kwekunze dhiraivha linear mota
Paunenge uchigadzira mitsara inofamba inoenderana zvigadzirwa kana mhinduro, isu tinokurudzira mainjiniya kuti atarise pane anotevera mapoinzi.
1. Chii chiri mutoro wehurongwa?
Kuremerwa kweiyo sisitimu kunosanganisira static mutoro uye ine simba mutoro, uye kazhinji saizi yemutoro inotaridza saizi yekutanga yemota.
Static load: iyo yakanyanya kusundidzira iyo screw inogona kumira pakuzorora.
Dynamic load: iyo yakanyanya kusunda iyo screw inogona kumira kana ichinge ichifamba.
2. Chii chinonzi mutsara wekumhanya kwemota?
Iyo yekumhanya yekumhanyisa mota yemutsara ine hukama zvakanyanya nekutungamira kwe screw, imwe revolution ye screw ndiyo imwe lead ye nati. Nekumhanya kwakaderera, zvinokurudzirwa kusarudza screw ine diki inotungamira, uye nekumhanya kwakanyanya, zvinokurudzirwa kusarudza yakakura screw.
3. Chii chinodiwa nekururama kwehurongwa?
Kurongeka chaiko: kurongeka kwesiruu kunowanzoyerwa nekurongeka kwemutsara, kureva kukanganisa pakati pekufamba chaiko nekufamba kwedzidziso mushure mekutenderedzwa sikururu kune inovava denderedzwa rakaoma.
Dzokorora kurongeka kwekugadzirisa: kudzokorora kurongeka kwemaitiro kunotsanangurwa sekururama kwegadziriro yekukwanisa kusvika panzvimbo yakatarwa kakawanda, inova chiratidzo chakakosha chegadziriro.
Backlash: backlash ye screw uye nati pakuzorora kana maviri axial hama inofambiswa huwandu. Sezvo nguva yekushanda ichiwedzera, iyo backlash inowedzerawo nekuda kwekupfeka. Kubhadhara kana kururamiswa kwekudzokera shure kunogona kuwanikwa neiyo backlash kubvisa nati. Kana bi-directional positioning ichidikanwa, backlash inonetsa.
4. Dzimwe sarudzo
Idzi dzinotevera nyaya dzinodawo kutariswa mukuita sarudzo: Iko kukwidziridzwa kweiyo linear stepper mota inoenderana neyakagadzirwa dhizaini? Ungabatanidza sei chinhu chinofamba nenzungu? Chii chinonzi sitiroko inoshanda yescrew rod? Ndeupi rudzi rwekutyaira ruchafananidzwa?
