Nrov Nema 17 Kaw voj stepper nrog cov khoom tshiab
Txhua yam ntawm cov neeg kho tshuab kev co uas tsim los ntawm lub cev muaj zog hauv kev ua haujlwm yuav hnav thiab corrode lub coil rwb thaiv tsev, qhov tseem ceeb tshaj plaws yog electromagnetic kev co, uas cuam tshuam rau lub rwb thaiv tsev ntawm lub cev muaj zog kawg winding thiab notch.Yog hais tias qhov nias zoo ntawm stator core tsis zoo, thiab cov txheej txheem winding kawg binding tsis zoo, lub kauj yuav plam hauv lub qhov, thiab cov interlayer gasket thiab ntsuas kub ntsuas lub ntsiab gasket yuav txav mus los ntawm sab sauv thiab qis coils. , uas yuav hnav lub sab sauv thiab qis coils thiab ua kom puas lub coil rwb thaiv tsev.Dab tsi ntxiv, yog tias lub coil khiav, qhov tam sim no dhau los ntawm cov hlau yuav tsim ob zaug ntawm electromagnetic vibration quab yuam, uas yuav tsis tsuas yog ua rau lub kauj coil vibrate nrog qhov sib nrug ntawm qhov kawg ntawm cov hlau core thiab winding, tab sis kuj ua rau kev sib txhuam kev vibration ntawm cov hlau thiab cov rwb thaiv tsev, nruab nrab ntawm cov lem thiab cov hlua ntawm cov hlau, uas ua rau xoob winding lem thiab strands, luv luv Circuit Court, disconnection thiab lwm yam teeb meem.Nyob rau tib lub sijhawm, kev poob ntxiv tshwm sim ntawm qhov luv-circuit, uas ua rau lub hauv paus kub ntawm lub winding nce sharply, lub rwb thaiv tsev lub zog yuav txo, thiab lub rwb thaiv tsev puas txhaum tshwm sim.Yog li ntawd, electromagnetic vibration yog lub ntsiab ua rau coil rwb thaiv tsev puas.
Qhov sib xyaw ntawm cov ntaub ntawv rwb thaiv tsev, laminated cores, coil xov hlau thiab lwm yam khoom siv hauv lub cev muaj zog ua rau nws cov txheej txheem rigidity thiab cov xwm txheej ntawm thermal expansion thiab txias contraction thaum lub sij hawm ua hauj lwm nyuaj, uas yog ib qho ntawm cov laj thawj rau lub cev muaj zog vibration.Qhov tsis sib npaug ntawm lub rotor, lub zog hluav taws xob hauv lub cev muaj zog, qhov torsional cuam tshuam ntawm lub cev muaj zog tom qab rub lub load, thiab qhov cuam tshuam ntawm daim phiaj hluav taws xob yuav ua rau muaj kev vibration ntawm lub cev muaj zog.
Kev vibration ntawm lub cev muaj teeb meem, piv txwv li, nws yuav khoov thiab tawg lub rotor ntawm lub cev muaj zog;Ua kom cov hlau nplaum ntawm lub cev muaj zog rotor xoob, ua rau lub cev muaj zog stator thiab rotor rubbing thiab bore cheb tsis ua haujlwm;Rau qee qhov, nws yuav ua rau kom lub cev muaj zog thiab ua kom lub neej zoo ntawm cov kabmob;Lub cev muaj zog winding xaus yog loosened, ua rau muaj kev sib txhuam ntawm qhov kawg windings, txo cov rwb thaiv tsev tsis kam, luv luv ntawm rwb thaiv tsev lub neej, thiab txawm tias rwb thaiv tsev tawg nyob rau hauv cov xwm txheej hnyav.
Cov khoom tseem ceeb uas cuam tshuam rau lub cev muaj zog muaj xws li lub cev muaj zog stator core, stator winding, lub cev muaj zog, rotor thiab cov kabmob.Kev vibration ntawm stator core feem ntau yog los ntawm electromagnetic quab yuam, uas ua rau elliptical, triangular, quadrilateral thiab lwm yam kev co hom.Thaum ib qho chaw sib nqus sib nqus dhau los ntawm stator laminated core, nws yuav tsim axial kev co.Yog tias cov tub ntxhais tsis tau nias kom nruj, cov tub ntxhais yuav tsim kev vibration hnyav, uas tuaj yeem ua rau cov hniav tawg.Txhawm rau tiv thaiv qhov kev vibration zoo li no, cov tub ntxhais stator feem ntau siv cov phaj nias thiab cov ntsia hlau compression qauv, tab sis tib lub sijhawm, yuav tsum tau them nyiaj mloog kom tsis txhob muaj kev puas tsuaj los ntawm lub zog hauv zos ntau dhau ntawm cov tub ntxhais.
Thaum lub sijhawm ua haujlwm ntawm lub cev muaj zog, stator winding feem ntau cuam tshuam los ntawm kev ua haujlwm ntawm lub zog tam sim no thiab cov dej ntws tawm hauv lub tshuab cua, sib nqus rub ntawm lub rotor, thermal expansion thiab contraction force ntawm winding, thiab lwm yam. system zaus los yog ob zaus vibration ntawm winding.Thaum tsim lub cev muaj zog, tshwj xeeb tshaj yog tsim nyog xav txog kev vibration ntawm lub qhov thiab sab saum toj ntawm stator winding los ntawm electromagnetic quab yuam.Txhawm rau tiv thaiv ob hom kev vibration no, nws yog ib qho tsim nyog yuav tsum tau ua ntau yam xws li cov qauv fastening ntawm qhov zawj bar thiab axial rigid bracket thaum kawg.
