Servo lub cev muaj hlau nplaum lossis Neodymium hlau nplaum rau servo lub cev muaj nws tus kheej tshwj xeeb thiab kev ua haujlwm siab kom tau raws li nruj zoo uas yuav tsum tau muaj rau servo motors. Servo lub cev muaj zog yog hais txog lub tshuab hluav taws xob uas tswj cov kev ua haujlwm ntawm cov khoom siv cav hauv tshuab servo. Nws yog ib qho hloov ua twj paj nruag ceev rau lub cev muaj zog pabcuam. Lub servo lub cev muaj zog tuaj yeem ua rau kev tswj lub suab nrawm thiab qhov chaw tau ua haujlwm kom raug, thiab tuaj yeem hloov lub teeb liab voltage rau hauv torque thiab nrawm rau tsav lub zog tswj. Lub rotor ceev ntawm servo lub cev yog tswj los ntawm lub teeb liab nkag thiab tuaj yeem hloov kho sai.

Txij li Indramat ceg ntawm Rexroth teb tsim MAC haujlwm ruaj nrees hlau nplaum AC servo lub cev muaj zog thiab tsav lub zog ntawm Hannover luam ncaj ncees xyoo 1978, qhov no qhia tau tias cov cim tshiab ntawm AC servo thev naus laus zis tau nkag mus rau hauv cov theem ua tau zoo. Los ntawm nruab nrab thiab thaum 1980s, txhua lub tuam txhab muaj cov khoom tiav ua tiav. Tag nrho servo kev ua lag luam yog tig mus rau AC systems. Feem ntau ntawm cov hluav taws xob ua haujlwm siab 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 kev ua haujlwm digital servo system nrog kev ceev thiab qhov chaw. Muaj cov neeg lag luam xws li Siemens, Kollmorgen, Panasonic, Yaskawa, thiab lwm yam.

Vim tias txoj haujlwm tseeb ntawm servo lub cev muaj zog, nws muaj qhov yuav tsum nruj txog kev ua haujlwm kom raug thiab qhov ua haujlwm siab, uas feem ntau yog nyob ntawm qhov ua tau zoo ntawm Neodymium cov hlau nplaum rau servo motors. Vim tias muaj ntau qhov kev sib nqus ntawm cov khoom sib nqus, Neodymium hlau nplaum ua rau servo lub cev muaj peev xwm ua nrog qhov hnyav dua thiab me dua qub piv nrog cov ntaub ntawv sib nqus, xws li Ferrite, Alnico lossis SmCo cov hlau nplaum.

Rau servo motor magnets, tam sim no Horizon Magnetics yog ua cov txog ntawm qib kawg ntawm Neodymium cov hlau nplaum, zoo li H, SH, UH, EH thiab AH nrog rau peb yam ntxwv:

1.High intrinsic coercivity Hcj: siab rau> 35kOe (> 2785 kA / m) uas nce cov hlau nplaum demagnetizing tsis kam thiab tom qab ntawd servo lub cev muaj zog ua haujlwm kev ua haujlwm

2. tsawg dua qhov kub rov qab hloov coefficients: qis rau Br (Br) <-0.1% / ºC thiab β (Hcj) <-0.5% / ºC uas ua kom cov hlau nplaum kub tsis tuaj yeem ua haujlwm thiab ua kom muaj cov servo lub cev muaj zog ua haujlwm nrog kev ruaj khov dua

3.Txaus poob phaus: qis rau 2 ~ 5mg / cm2 hauv HAST kev kuaj mob: 130ºC, 95% RH, 2.7 ATM, 20 hnub uas nce cov hlau nplaum tiv thaiv xaj kom ntev lub sijhawm ntawm servo motors
