Taw qhia rau Resolver rau Tshiab Zog Tsheb Tsav Tsheb
1. Txoj Cai
Resolver yog ib qho uas nquag siv nyob rau hauv kev tswj lub cev muaj zog. Lub luag haujlwm ntawm tus neeg daws teeb meem yog ntsuas qhov chaw, ceev thiab kev taw qhia ntawm kev sib hloov ntawm lub cev muaj zog rotor, thiab xa cov teeb liab no mus rau kev tswj hluav taws xob. Lub cev muaj zog yog tswj los ntawm software tswj algorithm.
Nws tuaj yeem tswj tau qhov zaus thiab ntu ntawm peb-theem alternating tam sim no, yog li hloov qhov ceev thiab kev taw qhia (rau pem hauv ntej thiab thim rov qab) ntawm lub tshuab tsav. Thaum cov hlau nplaum ruaj khov synchronous lub cev muaj zog ua haujlwm, qhov sib nqus sib nqus teb tsim los ntawm stator coil rotates synchronously nrog lub rotor, thiab cov hlau nplaum ntawm cov hlau nplaum rotating thiab cov hlau nplaum ntawm lub rotor yuav tuav ib lub kaum ntse ntse. Dab tsi saib xyuas txoj haujlwm thiab ceev ntawm lub rotor yog tus daws teeb meem.
Lub hauv paus ntsiab lus ntawm kev daws teeb meem: Los ntawm kev nkag mus rau lub teeb liab siab sinusoidal rau lub rotor coil, uas yog qhov peb feem ntau hu ua lub teeb liab excitation (lub hwj chim qhov chaw ntawm tus daws teeb meem), peb tuaj yeem tau txais cov teeb liab siab zaus induction pub rov qab los ntawm lub teeb liab. inductive daws rotor nyob rau hauv lub kauj. Tom qab ua tiav, cov ntaub ntawv sib txuas sine thiab cosine tuaj yeem tau txais, thiab tom qab kev tshuaj xyuas los ntawm software, qhov tseeb ntawm stator tuaj yeem tau txais.
2. Calibration
Muaj ntau cov ntsiab lus nrov rau calibration ntawm cov neeg daws teeb meem hauv kev ua haujlwm txhua hnub, xws li xoom lub kaum sab xis calibration, lub cav lub kaum sab xis calibration, thiab lwm yam. Txawm hais tias cov lus sib txawv, cov ntsiab lus thiab kev ua haujlwm yog tib yam, uas yog, koj yuav tsum paub qhov txawv ntawm qhov sib txawv. nruab nrab ntawm xoom txoj hauj lwm ntawm tus daws teeb meem thiab xoom txoj hauj lwm ntawm lub cev muaj zog.
3. Tej yam ua txhaum
Yog tias muaj teeb meem nrog tus daws teeb meem, yuav muaj teeb meem ceev ceev.
1. Thaum lub tsheb zoo li qub (qhov tseeb lub cev muaj zog yog xoom), qhov ntsuas tsis raug qhia tias lub cev muaj zog tig;
2. Nyob rau hauv ib txwm high-voltage tej yam kev mob, lub cev muaj zog tsis tso zis ceev thaum lub tsheb nyob rau hauv lub iav thiab cov kauj ruam ntawm lub accelerator;
3. Ua rau peb-theem hardware overcurrent txhaum;
4. Ua rau IGBT tsis ua haujlwm;
5. Ua rau lub cev muaj zog vibrate;
6. Ua rau lub cev muaj zog;
7. Kev vibration, suab txawv txav
Qhov kev daws teeb meem ntawm cov hlua khi hlua txuas txuas tsis raug. Ib qho txhaum tshiab tau tshwm sim: lub cev muaj zog dhau los ntawm kev tswj xyuas software thiab kho vajtse version, thiab thaum nkag mus rau NVH kev ua haujlwm, muaj lub suab nrov nrov, tus yam ntxwv nkhaus yog qhov txawv txav, thiab kev sib hloov ceev tsis zoo. Thaum kawg, qhov yuam kev hauv kev daws teeb meem hlau hlua tsim tau pom.
1) Los ntawm kev ntsuas hluav taws xob kom muaj nuj nqis
Feem ntau muaj 6 qhov kev daws teeb meem txuas los ntawm lub cev muaj zog tswj qhov kawg mus rau qhov kawg ntawm lub cev muaj zog, uas yog: ref± (excitation signal), sin ± (sine signal) thiab cos± (cosine signal). Txhua txheej ntawm cov teeb liab muaj nws tus kheej sib xws Resistance, koj tuaj yeem txiav txim siab seb nws puas yog kev daws teeb meem los ntawm kev ntsuas peb qhov kev daws teeb meem qhov tseem ceeb ntawm lub cev muaj zog tswj plug-in kawg lossis lub cev muaj zog kawg.
2) Cov yam ntxwv nkhaus
Lub cev muaj zog ceev yog lub teeb liab ntawm lub cev muaj zog torque, ib yam li lub iav. Yog tias koj xav kom lub iav tig, koj xav tau lub zog sab nraud.
Ib txwm lub cev muaj zog ceev hloov smoothly thiab linearly.
Abnormality: Lub cev muaj zog ceev nkhaus pom nyob rau hauv kev daws teeb meem tsis ua hauj lwm zoo li ib tug burr. Thaum lub sij hawm kev tsav tsheb ntawm lub tsheb, kev vibration ntawm lub cev muaj zog yuav ua rau kev tsav tsheb ntawm tag nrho lub tsheb.
Ib qho kawg ntawm kev daws teeb meem xaim hlua txuas nrog lub tshuab hluav taws xob qis qis ntawm lub tshuab hluav taws xob, thiab lwm qhov kawg yog txuas nrog cov kev daws teeb meem qis-voltage plug-in ntawm lub cev muaj zog. Peb muaj cov kev kuaj mob hauv qab no:
1) Tshem tawm cov hluav taws xob qis qis ntawm lub tshuab hluav taws xob thiab cov kev daws teeb meem qis-voltage plug-in ntawm lub cev muaj zog, thiab siv lub tshuab ntsuas ntau los ntsuas qhov txuas ntxiv ntawm excitation (ref±), sine (sin ±) thiab cosine ( cos ±);
2) Yog tias qhov ntsuas kev daws teeb meem yog qhov qub, tab sis nws tsis tuaj yeem txiav txim siab seb puas muaj teeb meem nrog kev sib txuas virtual ntawm cov hlua khi thiab cov ntsaws ntsaws, koj tuaj yeem nruab qhov hluav taws xob qis plug-ins ntawm ob qho kawg, rub lub xov hlau harness thiab co nws vigorously. Yog tias qhov ntsuas ntsuas ntsuas qhov ntsuas qhov txawv txav txawv txav, koj tseem yuav tsum ua tib zoo xyuas cov hlua hlau. thiab tsawg voltage plug-ins;
3) Yog tias qhov kev daws teeb meem ntsuas tau zoo li qub (los ntawm qhov qis-voltage plug-in kawg thiab lub cev muaj zog kawg ntawm tus tswj lub cev muaj zog), thiab cov hlua hluav taws xob thiab plug-in tau lees paub tias yog qhov qub, lub tshuab hluav taws xob yuav tsum tau hloov.
