Niaj hnub no, feem ntau ntawm spindle motors rau CNC precision machining siv tawb-hom AC peb-theem asynchronous motors. Nws tsis muaj qhov teeb meem ntawm cov pa roj carbon txhuam commutation ntawm DC lub cev muaj zog, thiab cov vector zaus hloov dua siab tshiab thev naus laus zis kuj ua rau kev ua haujlwm ntawm lub tawb asynchronous lub cev muaj zog tag nrho mus txog qib ntawm DC lub cev muaj zog, thiab nws muaj zog tshaj lub peev xwm, me me, thiab tag nrho. nyob ruaj ruaj-dawb.
Cov yam ntxwv nkhaus ntawm CNC precision machining lub cev muaj zog yog muab faib ua ob ntu, tus ntoo khaub lig torque ntawm qis ceev thiab lub zog tas li ntawm kev kub ceev. Muaj ib qho ntawm qhov kev sib tshuam ntawm ob qhov nkhaus, thiab qhov node yog hu ua qhov nrawm nrawm. Raws li qhov yooj yim ceev no, cov neeg kho tshuab qhov chaw machining Hoobkas feem ntau tsim lub gearbox rau hauv ob lub zog, uas ua rau nws yooj yim rau tus maub los tswj. Vim yog ob qho xwm txheej sib txawv, qhov kev hloov kho yog qhov sib txawv.
1. Transverse torque ntawm qis ceev, kev hloov ceev los ntawm kev kho armature voltage.
2. Lub zog tsis tu ncua ntawm kev kub ceev, kev tswj ceev los ntawm txoj kev kho cov excitation tam sim no.
Lub spindle ceev ntawm CNC precision machining, tsis hais qhov kev hloov kho yog siv, yog ua los ntawm inverter. Yog tias siv cov hlau nplaum ruaj khov synchronous AC lub cev muaj zog, nws tsis tuaj yeem ua haujlwm zoo hauv lub xeev tsis muaj zog hlau nplaum los ntawm nws tus kheej, thiab tom qab ntawd muaj cov txheej txheem pabcuam los ua kom tiav qhov kev txiav txim ntawm spindle. Rau xws li cov txheej txheem pab cuam, cov qauv tsim yuav muab tso rau hauv ib qho kev sib cais rau kev tswj, uas yog vim li cas vim li cas qee qhov loj precision mechanical qhov chaw machining tshuab siv peb lub blocks.
Tam sim no, CNC precision machining spindle tsav ib qhov torque ceev ntau qhov piv ntawm mus txog 1: 100, tas li lub zog ceev qhov sib piv ntawm mus txog 1:30, tas li torque thiab tas li lub zog ceev ntau qhov piv rau 1 : 2, overload 1.5 zaug tseem tuaj yeem ua haujlwm ntxiv 30min. Piv txwv li, lub spindle ntsuas ceev 1500 / min, ces cov iav yuav tsum tau muab sib cais ntawm 500r / min txoj hauj lwm, qis iav Yam tsawg kawg nkaus 5 / min, mechanical parts processing plant good some gear vice, can speed down to 0.5min.
