| Pickup ua unreliable thaum sov | Muab headroom, coil winding kuj thiab davhlau ya nyob twg poob | Ntsuas coil davhlau ya nyob twg voltage thiab tam sim no ntawm kev khiav hauj lwm kub |
| Rov ua dua kev tiv thaiv kev tsav tsheb | Clamp zog, overcurrent, luv los yog tsis raug tso zis configuration | Tshawb xyuas cov tsav tsheb tsis raug cai thiab siv tau cov qauv waveform tam sim no kom nyab xeeb |
Yog tias cov cables sab nraud, cov khoom sib txuas lossis cov khoom thauj raug puas, cais thiab kho lawv raws li cov txheej txheem tshuab pom zoo. Yog tias xav tias muaj kev sib cuag tsis ruaj khov, siv qhov kev tiv thaiv kev tiv thaiv thiab kev ntsuas waveform es tsis txhob txhais cov solenoid ncua sij hawm raws li qhov tsis muaj nuj nqis ntawm lub nplhaib tsis kam.
Qhia meej qhov kev cai sib cuam tshuam nrog rau kev npaj txais inductive-load
Ib tus neeg muag khoom xav tau ntau tshaj li cov xov tooj hluav taws xob thiab cov npe ntawm cov coil voltages. Qhia tus tsav tsheb thiab coil architecture, txoj hauv kev hauv Circuit Court, cov khoom siv tiv thaiv, kev coj tus cwj pwm ib txhij thiab kev lees paub. Qhov no yuav pab txiav txim seb tus qauv sib dhos puas haum lossis seb qhov project xav tau kev hloov kho lossis kev cai teeb tsa.
| RFQ teb | Cov ntaub ntawv xav tau ntawm qhov project | Vim li cas tus neeg muag khoom xav tau nws |
|---|---|---|
| Rotary architecture | Dab tsi yog nyob ruaj ruaj, dab tsi tig, qhov chaw ntawm tus tsav tsheb thiab coils | Txhais kev pub, rov qab thiab mounting lub luag haujlwm |
| Coil xav tau | Tus naj npawb, nominal / tso cai voltage, khaws / tuav tam sim no, actuation / tso sijhawm | Txhais kev ua haujlwm load ntau dua li 24 V daim ntawv lo |
| Hloov | High-sab / qis-sab / choj tsav tsheb, qhib / tawm lossis PWM, lub voj voog zaus thiab lub luag haujlwm | Txhais waveform thiab hluav taws xob kev nyuaj siab |
| Txhaum | Chaw tsim tshuaj paus-pom zoo diode, clamp los yog kev tiv thaiv thiab nws qhov chaw | Txhais txoj kev tso tawm thiab tso cai rau ncua sijhawm |
| Lwm cov channel | Lub cev muaj zog, sensor, encoder thiab kev sib txuas lus circuits; grounding/shields | Txhais kev sib cais thiab kev sim ib txhij |
| Mechanical/ib puag ncig | Muaj bore / OD / ntev, RPM, reversals, leads, connectors, vibration thiab kub | Txhais kev sib koom ua ke thiab kev ua haujlwm tiag tiag |
| Txais | Coil davhlau ya nyob twg waveform, tam sim no lwj, voltage poob, actuation lub sij hawm, teeb liab yuam kev | Muab lub hom phiaj pass/fail pov thawj |
Thaum tus qauv tsim tsis tuaj yeem txheeb xyuas nrog lub rooj sib dhos uas twb muaj lawm, xa cov khoom siv hluav taws xob thiab cov tshuab ua kom tiav los ntawmByTune txoj kev cai swb nplhaib engineering nplooj. Kev pom zoo ntawm tus qauv tiag tiag yuav tsum ua raws li kev pom zoo ntawm qhov tseeb ntawm qhov ntsuas hluav taws xob, qhov ntev, qhov ntsuas qhov ntsuas thiab cov ntaub ntawv pom zoo; kab lus no tsis txiav txim siab ntawm nws tus kheej.
Qhov txiaj ntsig zoo tshaj plaws yog kev siv hluav taws xob siv hluav taws xob, tsis yog kev lees paub thoob ntiaj teb.Daim ntawv qhia txoj hauv kev khaws cia-zog tawm, txheeb xyuas cov coil khaws thiab tso tawm raws li txoj kev xaiv tsa, thiab sim ua tiav cov txheej txheem rotary nrog cov neeg sawv cev thiab cov khoom thauj ib txhij. Qhov ntawd yog li cas cov engineers paub qhov txawv ntawm qhov teeb meem ntawm lub nplhaib los ntawm lub coil-tsav tsheb los yog teeb meem-tsim teeb ua ntej yuav hloov pauv kim.
