Lub cev muaj zog stator thiab rotor txog kev taw qhia
Ua kom yooj yim: qhov chaw ruaj ntawm lub cav yog hu ua stator, uas tus khub DC-excited nyob ruaj ruaj lub ntsiab ncej yog mounted; thiab hloov qhov (rotor-rotor) yog hu ua tub ntxhais kev sib txuas, uas yog kev txhawb rau nws. Lub siab ntsig txog qhov sib zog ua rau lub zog qeeb zog tom qab ua lub zog, thiab ua raws li ib thaj chaw tig magnetic los ua hluav taws xob ntawm lub tshuab hluav taws xob hloov mus rau lub tshuab hluav taws xob. Cov duab ntawm lub stator winding yog txawv ntawm lub hom. Lub stator winding tau muab faib ua ob hom raws li cov qauv ntawm cov cua txias thiab txoj kev ntawm cov hlua khi. Ua kom yooj yim: qhov chaw ruaj ntawm lub cav yog hu ua stator, uas tus khub DC-excited nyob ruaj ruaj lub ntsiab ncej yog mounted; thiab hloov qhov (rotor-rotor) yog hu ua tub ntxhais kev sib txuas, uas yog kev txhawb rau nws. Lub siab ntsig txog qhov sib zog ua kom muaj kev sib tw ntawm electromotive tom qab ua energized thiab ua raws li lub teb chaw magnetic. Lub tshuab electromagnetic torque yog tsim los hloov ua lub zog. Cov duab ntawm tus stator winding yog qhov txawv ntawm hom embedded. Tus stator winding yog txawv raws li cov duab ntawm cov coil winding thiab cov thaiv ntim. Muab faib ua ob hom: centralized thiab muab faib.
Kev ua yeeb yam ntawm tus cwj pwm ruaj ruaj
Cov kab nrig rotor tseem yog ib qho siv los tiv thaiv kev tiv thaiv hauv kev siv hluav taws xob, thiab muaj kev tua hluav taws zoo hauv cov suab nrov, thiab feem ntau yog ua los ntawm cov khoom siv ferrite. Muaj ntau tus neeg tsis paub txog qhov rotor core. Yuav kom qhia koj paub ntau ntxiv txog peb cov khoom thiab kom koj paub, Xiaobian qhia koj mus rau qhov kev ua tau zoo ntawm tus qauv stator.
1. Tsawg coercivity Cov kev sib nqus hlau permeability thawj zaug siab: nws tuaj yeem txo qhov kev khiav hauj lwm tam sim no ntawm txoj kev hloov xau.
2, siab khaus magnetic induction: nws zoo rau xaiv ntau dua ua haujlwm magnetic induction taw tes.
3, ruaj rotor core high magnetic permeability: zoo heev txhim kho qhov tseeb ntawm qhov kev hloov tshuab, txo qhov sib txawv.
4, lub cev nyhav, qis tus nqi: tus nqi yog qhov zoo tshaj li permalloy.
5, muaj peev xwm tiv thaiv tsis tau zoo thiab muaj kev ruaj siab kub zoo: tuaj yeem ua haujlwm ntawm 55-1-1 ° C ntev ntev.
Cov teeb meem cuam tshuam rau qhov teeb tsa ntawm lub rotor core
Cov rotor tub ntxhais ploj zuj zus tuaj yeem yog qhov zoo tshaj plaws pwm nrog kev ua haujlwm siab, siab dua thiab lub neej ntev, thiab nws daim ntawv thov khov yog dav dav thiab dav. Raws li tus yuam sij rau txoj kev vam meej ntawm cov pwm tsim, qhov khij nyiab layout yeej pom cov qauv ntawm tag nrho cov pwm thiab ncaj qha cuam tshuam rau qhov zoo ntawm qhov ntau lawm. Muaj ntau ntau yam cuam tshuam rau cov kab xev ntim hauv qhov tseeb ntau lawm. Feem ntau, tus stator tseem yuav tau ua tiav raws li nram no:
(1) Cov khoom lag luam. Nws yog qhov tseem ceeb tshaj plaws uas cuam tshuam rau kev teeb tsa. Feem ntau muaj xws li: 1 stator, rotor, hom stator, qhov loj thiab qhov tseeb ntawm cov cai; 2 ruaj rotor yuav tsum tau xoob los yog hlau tub ntxhais (muab faib ua tus stator, rotor yuav tsum tau riveted, ib pawg ntawm riveting ib thooj, ob leeg yog tawg (), qhov no yuav cuam tshuam cov qauv tsim thiab txheej txheem kev ua tiav; 3) Yog lub rotor xav tau kev sib tw, yog tias nws xav tau kev sib tw, txoj hauj lwm ntawm txoj kev sib koom tes yuav tsum tau xav txog, thiab qhov chaw ua haujlwm yuav tsum tau ntxiv thaum lub caij tsim.
(3) Hom kev teeb tsa. Qhov layout feem ntau yog nyob rau hauv ib kab, ob chav leej, los yog peb kab. Kev siv cov ntaub ntawv yog qhov kev ntsuas loj.
(5) Pwm cov yam ntxwv. Rau cov khoom uas yuav tsum tau muab sib tw thiab riveted, nws yog ib qhov tsim nyog yuav tsum tau xav txog qhov chaw ntawm lub taub hau torsion, thiab nws yog feem ntau tsim nyog los nce qhov chaw ua hauj lwm tas. Nyob rau hauv lub cav tub ntxhais ploj zuj zus, qhov punch feem ntau yog nyob rau ntawm lub punch fixing phaj los ntawm kev siv lub phaj nias, thiab lub phaj nias yog txuas nrog screws, thiab nws yog qhov yuav tsum tau xav txog seb puas muaj txaus platen chaw thaum txhaws. Seb tus cwj pwm ntawm tus cwj pwm uas tau xa tawm los ntawm siv los yog ib daim ntawv qhia kev tawm lub tsho yuav cuam tshuam cov pwm qauv.
(6) Cov kev cai tshwj xeeb ntawm cov neeg siv khoom. Nws yog tsuas yog cov kev cai ntawm cov neeg muas zaub raws li lawv tus kheej cov neeg mob. Piv txwv, kom txo tau cov nqi, yog lub thickness ntawm silicon steel sheet khoom siv rau blanking muaj ib qhov kev ua yuam kev uniformity, nws feem ntau yuav tsum tau ua 180 loj tig thaum lub caij lamination los xyuas kom meej rau tub ntxhais siab siab, uas yuav cuam tshuam qhov teeb tsa.
