Li cas Linear Motors Ua Haujlwm

Linear motors yog qhov tseem ceeb "unrolled" versions ntawm cov motors teb uas tsim tawm cov lus tsa suab ncaj qha yam tsis tas yuav muaj kev hloov kho tshuab xws li pob ntsia hlau lossis siv hlua. Lawv muaj ib feem (forcer) uas muaj electromagnetic coils thiab ib tug thib ob (platen los yog hlau nplaum khiav) uas generates ib magnetic teb. Thaum cov hluav taws xob tam sim no ntws los ntawm cov coils, nws cuam tshuam nrog cov magnetic teb los tsim cov kab ncaj nraim.

Cov yam ntxwv tseem ceeb ntawm Linear Motors:

Direct drive system (tsis muaj cov khoom sib kis tau zoo)

High acceleration thiab ceev (qee qauv tshaj 10 m / s)

Qhov chaw meej heev (sub-micron daws teeb meem tau)

Zoo tsis muaj backlash lossis mechanical hnav

High dynamic teb (zoo tagnrho rau kev txav ceev)

Tsawg stroke ntev (tshwj tsis yog siv cov hlau nplaum txuas ntxiv)

Stepper Motors Ua Haujlwm li cas

Stepper motors yog cov motors teb uas txav mus rau hauv cov kauj ruam tsis sib xws, hloov hluav taws xob pulses mus rau qhov tseeb txhua yam kev sib hloov. Lawv ua hauj lwm los ntawm energizing coil theem nyob rau hauv ib theem zuj zus, ua rau lub rotor (uas muaj cov hlau nplaum tas mus li) mus ua ke nrog cov magnetic teb increments. Thaum ua ke nrog cov ntsia hlau txhuas lossis lwm cov tshuab tshuab, lawv tuaj yeem tsim cov lus tsa suab tsis ncaj.

Cov yam ntxwv tseem ceeb ntawm Stepper Motors:

Qhib-loop tswj (feem ntau tsis xav tau kev tawm tswv yim)

Zoo tuav torque thaum nyob ruaj ruaj

Zoo low-speed torque yam ntxwv

Precise positioning (feem ntau 1.8 ° ib kauj ruam, los yog 200 kauj ruam / kiv puag ncig)

Nqi-zoo rau ntau daim ntawv thov

Yuav poob cov kauj ruam yog tias overloaded

Qhov sib txawv tseem ceeb ntawm Linear thiab Stepper Motors

1. Hom lus tsa suab

Linear Tsav: Tsim cov kab ncaj nraim ncaj nraim

Stepper Tsav: Ua kom muaj kev sib hloov (yuav tsum tau hloov dua siab tshiab rau linear txav)

2. Mechanical complexity

Linear Tsav: Yooj yim zuag qhia tag nrho system nrog tsawg dua qhov txav

Stepper Tsav: Yuav tsum muaj cov khoom siv ntxiv (cov hlau lead, siv tawv, thiab lwm yam) rau cov ntawv thov kab

3. Ceev thiab nrawm

Linear Tsav: Superior acceleration (feem ntau> 10 m / s²) thiab kev kub ceev

Stepper Tsav: Txwv los ntawm cov khoom siv tshuab thiab cov yam ntxwv torque

4. Precision thiab daws teeb meem

Linear Tsav: Sub-micron daws teeb meem ua tau nrog cov lus pom zoo

Stepper Tsav: Txwv los ntawm cov kauj ruam loj (feem ntau ~ 0.01mm nrog zoo mechanics)

5. Kev Kho Kom Zoo

Linear Tsav: Zoo saib xyuas-dawb (tsis muaj qhov sib cuag)

Stepper Tsav: Mechanical Cheebtsam yuav tsum tau saib xyuas raws sijhawm

6. Kev txiav txim siab nqi

Linear Tsav: Tus nqi pib siab dua tab sis muaj peev xwm txo tus nqi lub neej

Stepper Tsav: Tus nqi qis dua tab sis tej zaum yuav muaj kev siv nyiaj ntau dua

7. Cov yam ntxwv quab yuam / Torque

Linear Tsav: Lub zog sib npaug ntawm qhov nrawm

Stepper Tsav: Torque txo qis nrog ceev

Thaum twg los xaiv Linear Tsav
