Tsav piav qhia / lub cev muaj zog tig

1. Txoj Cai

 

Resolver yog ib txoj hauj lwm sensor feem ntau siv hauv kev tswj lub cev muaj zog, lub luag haujlwm ntawm kev daws teeb meem yog ntsuas qhov chaw, nrawm thiab kev sib hloov ntawm lub cev muaj zog rotor, xa cov teeb liab no mus rau kev tswj hluav taws xob, thiab tswj lub cev muaj zog los ntawm kev tswj hwm algorithm ntawm software. .

 

Nws tuaj yeem tswj tau qhov zaus thiab ntu ntawm peb-theem alternating tam sim no, kom qhov ceev thiab kauj (rau pem hauv ntej thiab thim rov qab) ntawm lub tshuab tsav tuaj yeem hloov pauv. Thaum cov hlau nplaum ruaj khov synchronous lub cev muaj zog ua haujlwm, lub rotating magnetic teb generated los ntawm stator coil rotates synchronously nrog lub rotor, thiab lub rotating magnetic teb ncej thiab lub rotor ncej yuav tuav ib tug tej lub kaum sab xis, thiab cov kev hloov pauv yog cov kev sib hloov uas saib xyuas lub txoj hauj lwm thiab ceev ntawm lub rotor.

 

Lub hauv paus ntsiab lus ntawm rotating: los ntawm kev nkag mus rau lub high-frequency sinusoidal teeb liab mus rau lub rotor kauj, uas yog, peb feem ntau hu rau lub excitation teeb liab (lub hwj chim mov ntawm tus daws teeb meem), ces peb yuav tau txais lub high-frequency induction teeb liab pub rov qab los ntawm lub excitation teeb liab. induced rotor nyob rau hauv lub kauj, thiab cov ntaub ntawv sib xws sine thiab cosine tuaj yeem tau txais tom qab ua tiav, thiab qhov tseeb ntawm stator tuaj yeem tau txais tom qab kev tshuaj xyuas software.

 

2. Calibration

 

Muaj ntau cov lus hais nrov nrov hauv kev ntsuas kev hloov pauv hloov pauv 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, kom paub qhov sib txawv ntawm qhov sib txawv ntawm qhov xoom txoj hauj lwm ntawm kev sib hloov thiab xoom txoj hauj lwm ntawm lub cev muaj zog.

 

3. Kev ua tsis tiav

Yog hais tias muaj teeb meem nrog kev sib hloov, ces yuav muaj ib qho teeb meem ntawm kev sib hloov ceev.

1. Nyob rau hauv qhov xwm txheej zoo li qub ntawm lub tsheb (qhov tseeb lub cev muaj zog yog xoom), qhov ntsuas tsis raug ceeb toom tias lub cev muaj zog ceev;

2. Nyob rau hauv high voltage tej yam kev mob, lub iav pedal lub cev muaj zog tsis muaj tso zis ceev;

3. Ua rau peb-theem hardware overcurrent txhaum;

4. Ua rau IGBT tsis ua haujlwm;

5. Ua rau lub cev muaj zog ceev jitter:

6. Ua rau lub cev muaj zog;

7. Kev vibration, suab nrov txawv txav;

Ib qho txhaum tshiab tshwm sim los ntawm qhov tsis ncaj ncees lawm ntawm kev sib hloov txoj hlua: lub cev muaj zog dhau qhov kev tshawb pom ntawm software thiab kho vajtse version ntawm tus maub los, thiab NVH kev ua haujlwm tau tshwm sim rau nyem thiab lub suab nrov txawv txav, tus yam ntxwv nkhaus yog qhov txawv txav, qhov ceev tsis zoo. , thiab thaum kawg qhov kev tsim yuam kev ntawm kev daws teeb meem tau pom.

Dhau qhov ntsuas hluav taws xob

Feem ntau muaj 6 cov kab txuas txuas nrog lub cev muaj zog los ntawm qhov kawg ntawm tus tswj lub cev muaj zog, uas yog: ref± (excitation signal), sin ± (sinusoidal signal) thiab cos± (cosine signal), txhua pab pawg ntawm cov teeb liab yog chord teeb liab) thiab cos ± (cosine teeb liab), txhua pab pawg ntawm cov teeb liab muaj nws tus kheej tus nqi tsis zoo, koj tuaj yeem txiav txim siab seb nws puas yog qhov kev hloov pauv los ntawm kev ntsuas peb pawg ntawm kev sib hloov 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 ib tug khub teeb liab ntawm lub cev muaj zog torque, ib yam li lub iav, koj xav kom lub iav tig, ces yuav tsum tau ib tug sab nraud quab yuam.

Lub cev muaj zog ib txwm hloov maj mam thiab linearly.

Smooth thiab sib npaug, silky smooth

Abnormality: Lub cev muaj zog ceev nkhaus pom nyob rau hauv ib tug rotator txhaum zoo li ib tug burr. Thaum lub sij hawm kev tsav tsheb ntawm lub tsheb, vim yog jitters ntawm lub cev muaj zog ceev, nws yuav ua rau lub tsheb co ntawm tag nrho cov tsheb.

 

Rotary harness, ib kawg yog txuas mus rau qhov tsawg-voltage plug-in ntawm lub cev muaj zog maub los, thiab lwm kawg yog txuas nrog lub low-voltage plug-in ntawm lub cev muaj zog, peb muaj cov nram qab no diagnostic txhais tau tias:

 

1) Tshem tawm cov hluav taws xob qis qis ntawm lub tshuab hluav taws xob kawg thiab qhov kev daws teeb meem-tsis tshua muaj hluav taws xob plug-in ntawm lub tshuab hluav taws xob kawg, thiab siv lub tshuab hluav taws xob los ntsuas qhov kev tawm ntawm excitation (ref ±), sine ( sin±) thiab cosine (cos±);

 

2) Yog tias qhov ntsuas qhov tsis zoo ntawm qhov kev sib hloov yog qhov qub, tab sis tsis tuaj yeem txiav txim siab seb cov hlua khi thiab plug-in virtual kev twb kev txuas teeb meem, koj tuaj yeem nruab qhov qis-voltage plug-in ntawm ob qho kawg, rub lub hlua khi thiab co nws lub zog, yog tias qhov ntsuas qhov ntsuas tau hloov pauv txawv txav, nws tseem yuav tsum tau ua tib zoo xyuas cov hlua hluav taws xob thiab cov hluav taws xob qis qis;

 

3) Yog tias qhov ntsuas ntsuas qhov ntsuas qhov ntsuas tsis zoo yog qhov qub (los ntawm qhov qis-voltage plug-in kawg ntawm lub cev muaj zog thiab lub cev muaj zog kawg), thiab nws tau lees paub tias cov hlua khi thiab ntsaws ntsaws yog qhov qub, tus maub los lub cev muaj zog xav tau. hloov.
