Lub servo lub cev muaj zog hlau nplaum ua kom cov servo motors ua kom tswj tau qhov ceev thiab qhov tseeb ntawm qhov chaw, thiab tuaj yeem hloov cov teeb liab voltage rau torque thiab ceev kom tsav cov khoom tswj.Lub rotor ceev ntawm servo lub cev muaj zog yog tswj los ntawm cov teeb liab tawm tswv yim thiab tuaj yeem hnov mob sai.
Txij li thaum Indramat ceg ntawm Rexroth officially launched MAC mus tas li hlau nplaum AC servo lub cev muaj zog thiab tsav system ntawm Hannover kev lag luam ncaj ncees nyob rau hauv 1978, qhov no cim hais tias lub tiam tshiab ntawm AC servo technology tau nkag mus rau hauv lub tswv yim theem.Los ntawm nruab nrab thiab lig xyoo 1980s, txhua lub tuam txhab muaj cov khoom ua tiav.Tag nrho cov lag luam servo tig mus rau AC systems.Feem ntau ntawm cov kev ua haujlwm siab hluav taws xob servo tshuab siv cov hlau nplaum ruaj khov synchronous AC servo lub cev muaj zog, thiab tus neeg tsav tsheb tswj feem ntau siv tag nrho cov haujlwm digital servo system nrog ceev thiab raug qhov chaw.Muaj cov chaw tsim khoom xws li Siemens,Kollmorgen, Panasonic,Yaskawa, lwm.
Vim yog lub luag haujlwm ntawm servo lub cev muaj zog, nws muaj qhov yuav tsum tau ua nruj me ntsis txog kev ua haujlwm raug thiab kev ua haujlwm siab, uas feem ntau yog nyob ntawm qhov zoo ntawm Neodymium hlau nplaum rau servo motors.Vim muaj ntau yam khoom sib nqus ntau dua, Neodymium hlau nplaum ua rau cov servo motors tau nrog qhov hnyav thiab me me piv rau cov khoom siv hlau nplaum, xws li Ferrite, Alnico lossis SmCo hlau nplaum.
Rau servo lub cev muaj zog hlau nplaum, tam sim no Horizon Sib Nqus tau tsim cov qib siab kawg ntawm Neodymium hlau nplaum, zoo li H, SH, UH, EH thiab AH nrog peb yam nram qab no:
1.High intrinsic coercivity Hcj: siab mus> 35kOe (> 2785 kA / m) uas ua rau kom cov hlau nplaum demagnetizing tsis kam thiab ces servo lub cev muaj zog ua hauj lwm stability
2.Low reversible kub coefficients: qis rau α(Br) < -0.1% / ºC thiab β(Hcj) < -0.5% / ºC uas ua rau kom cov hlau nplaum kub stability thiab ua kom servo motors ua hauj lwm nrog ntau dua stability
3.Kev poob phaus: qis rau 2 ~ 5mg / cm2 hauv HAST kuaj mob: 130ºC, 95% RH, 2.7 ATM, 20 hnub uas ua rau cov hlau nplaum corrosion tiv thaiv kom ntev lub neej ntawm servo motors
Ua tsaug rau peb cov kev paub nplua nuj hauv kev muab cov tuam txhab servo lub cev muaj zog nrog cov hlau nplaum, Horizon Magnetics nkag siab txog servo lub cev muaj zog hlau nplaum xav tau cov kev ntsuam xyuas dav dav los xyuas kom meej nws cov khoom zoo, xws lidemagnetization nkhausntawm qhov kub thiab txias kom pom kev ua haujlwm ruaj khov, PCT & SST kom kawm tau zoo ntawm cov txheej txheej txheej, HAST kom pom qhov poob phaus, cua sov ntawm qhov kub thiab txias kom paub qhov poob ntawm qhov tsis tuaj yeem, sib nqus flux sib txawv los txo lub cev muaj zog jitter, thiab lwm yam.
