Kodi Pali Kusiyana Kotani Pakati pa Linear Motor ndi Stepper Motor?

Mukasankha injini yoyenera kuti mugwiritse ntchito makina anu, ma robotiki, kapena makina owongolera molunjika, kumvetsetsa kusiyana kwa ma linear motors ndi ma stepper motor ndikofunikira. Zonsezi zimagwira ntchito zosiyanasiyana m'mafakitale ndi malonda, koma zimagwira ntchito mosiyanasiyana. Maupangiri atsatanetsatane awa amawunika kusiyana kwawo kwakukulu pamamangidwe, magwiridwe antchito, magwiridwe antchito, ndi njira zabwino zogwiritsira ntchito kuti zikuthandizeni kupanga chisankho mwanzeru.

Kumvetsetsa Linear Motors

Momwe Linear Motors Amagwirira Ntchito

Ma Linear motors kwenikweni ndi mitundu "yosasunthika" yama mota ozungulira omwe amapanga kuyenda molunjika mosafunikira makina osinthira ngati zomangira za mpira kapena malamba. Amakhala ndi gawo loyambirira (forcer) lomwe lili ndi ma coil a electromagnetic ndi gawo lachiwiri (plate kapena magnet track) lomwe limapanga mphamvu ya maginito. Mphamvu yamagetsi ikadutsa pamakoyilo, imalumikizana ndi maginito kuti ipange kuyenda molunjika.

Makhalidwe Ofunikira a Linear Motors:

Direct drive system (palibe zida zotumizira makina)

Kuthamanga kwambiri komanso kuthamanga (mitundu ina imadutsa 10 m/s)

Kuyika kolondola kwambiri (kutheka kwa sub-micron)

Pafupifupi palibe m'mbuyo kapena kuvala makina

Kuyankha kwamphamvu kwambiri (koyenera kuyenda mwachangu)

Utali wochepa wa sitiroko (pokhapokha mutagwiritsa ntchito maginito otalikirapo)

Kumvetsetsa Stepper Motors

Momwe Stepper Motors Amagwirira Ntchito

Ma Stepper motors ndi ma mota ozungulira omwe amayenda mozungulira, kutembenuza ma pulse amagetsi kukhala makina ozungulira. Amagwira ntchito popatsa mphamvu magawo a coil motsatizana, zomwe zimapangitsa kuti rotor (yomwe imakhala ndi maginito okhazikika) kuti igwirizane ndi mphamvu ya maginito mu increments. Zikaphatikizidwa ndi zomangira zamtovu kapena makina ena amakina, zimatha kusuntha mosalunjika.

Makhalidwe Ofunikira a Stepper Motors:

Kuwongolera kotsegula (nthawi zambiri sikufuna mayankho)

Kugwira torque kwabwino mukayima

Makhalidwe abwino a torque otsika

Kuyika bwino (nthawi zambiri 1.8° pa sitepe, kapena masitepe 200/kusintha)

Zotsika mtengo pamapulogalamu ambiri

Itha kutaya masitepe ngati yadzaza

Kusiyana Kwakukulu Pakati pa Linear ndi Stepper Motors

1. Mtundu Woyenda

Linear Motor: Imapanga zoyenda molunjika mwachindunji

Stepper Motor: Imapanga zoyenda mozungulira (imafuna kutembenuka kwa mzere wozungulira)

2. Kuvuta kwa Makina

Linear Motor: Makina osavuta onse okhala ndi magawo ochepa osuntha

Stepper Motor: Imafunikira zida zowonjezera (zowongolera zowongolera, malamba, ndi zina) pazogwiritsa ntchito mzere.

3. Kuthamanga ndi Kuthamanga

Linear MotorKuthamanga kwapamwamba (nthawi zambiri> 10 m/s²) komanso kuthamanga kwambiri

Stepper Motor: Zochepa ndi zida zamakina ndi mawonekedwe a torque

4. Kulondola ndi Kukhazikika

Linear Motor: Kusintha kwa ma micron kotheka ndi mayankho oyenera

Stepper Motor: Pang'ono ndi sitepe kukula (nthawi zambiri ~ 0.01mm ndi zimango zabwino)

5. Zofunikira Zosamalira

Linear Motor: Zopanda kukonza (palibe magawo olumikizana)

Stepper Motor: Zipangizo zamakina zimafunikira kukonzedwa pafupipafupi

6. Kuganizira za Mtengo

Linear Motor: Kukwera mtengo koyambirira koma kutsika mtengo wamoyo wonse

Stepper Motor: Kutsika mtengo wapatsogolo koma kungakhale ndi ndalama zambiri zokonzetsera

7. Mphamvu / Torque Makhalidwe

Linear Motor: Mphamvu yosasinthasintha pama liwiro osiyanasiyana

Stepper Motor: Torque imachepa kwambiri ndi liwiro

Nthawi Yoyenera Kusankha Linear Motor

Ma Linear motors amapambana pamapulogalamu omwe amafunikira:

Kuyika kwapamwamba kwambiri (kupanga semiconductor, makina owoneka)

Kuthamanga kwambiri (kuyika, kusanja machitidwe)

Malo oyeretsera (palibe tinthu tating'ono kuchokera kumakina)

Kudalirika kwa nthawi yayitali ndi kukonza kochepa

Zofunikira zoyendetsa molunjika pomwe kubweza kwamakina sikuvomerezeka

Nthawi Yomwe Mungasankhe Stepper Motor

Stepper motors ndi yabwino kwa:

Mapulogalamu otsika mtengo okhala ndi zofunikira zolondola kwambiri

Kachitidwe komwe kugwira torque ndikofunikira

Njira zowongolera zotseguka pomwe kuphweka kumayamikiridwa

Mapulogalamu othamanga otsika mpaka apakatikati

Zinthu zomwe mwaphonya nthawi zina sizowopsa

Mayankho a Hybrid: Linear Stepper Motors

Ntchito zina zimapindula ndi ma linear stepper motors, omwe amaphatikiza mbali zonse zaukadaulo:

Gwiritsani ntchito mfundo zamagalimoto a stepper koma pangani zoyenda molunjika

Perekani mwatsatanetsatane kuposa ma stepper ozungulira okhala ndi makina osinthika

Zotsika mtengo kuposa ma motors enieni amzere koma zoperewera

Future Trends in Motion Control

Mawonekedwe aukadaulo wamagalimoto akupitilizabe kusintha:

Mapangidwe opangidwa bwino a liniya amachepetsa ndalama

Makina otsekeka otsika akutsekereza kusiyana kwa magwiridwe antchito

Owongolera anzeru ophatikizika akupanga njira zonse ziwiri kuti zitheke

Kupititsa patsogolo kwazinthu kukuwonjezera mphamvu komanso kuchuluka kwa mphamvu

Kupanga Kusankha Bwino pa Ntchito Yanu

Ganizirani izi posankha pakati pa ma linear ndi stepper motors:

Zofunikira mwatsatanetsatane

Liwiro ndi mathamangitsidwe zofunika

Bajeti yomwe ilipo (yoyamba komanso yayitali)

Maluso osamalira

Zoyembekeza za moyo wadongosolo

Mikhalidwe ya chilengedwe

Pazinthu zambiri zogwira ntchito kwambiri, ma injini amzere amapereka kuthekera kosayerekezeka ngakhale ndi mtengo wokwera. Pazinthu zambiri zamafakitale pomwe magwiridwe antchito safunikira, ma stepper motors amakhalabe njira yotsika mtengo komanso yodalirika.

Pomvetsetsa kusiyana kofunikira kumeneku pakati pa ma linear motors ndi ma stepper motors, mutha kupanga chisankho chodziwitsidwa chomwe chimakulitsa magwiridwe antchito, kudalirika, komanso mtengo wathunthu wa umwini pazomwe mukufuna.
