3. Los ntawm kev kho lub armature voltage, thiab los ntawm altering lub armature kuj
4. Los ntawm kev tswj cov flux, thiab los ntawm kev tswj cov tam sim no los ntawm cov teb winding
Tshawb xyuas cov no4 txoj hauv kev los tweak qhov ceevDC lub cev muaj zog:
1. Kev sib txuas ntawm DC Speed Controller
Lub gearbox, uas koj kuj yuav hnov hu ua lub iav reducer lossis ceev reducer, tsuas yog ib pawg ntawm cov iav uas koj tuaj yeem ntxiv rau koj lub cev muaj zog kom nws qeeb qeeb thiab / lossis muab lub zog ntau dua. Nws qeeb npaum li cas yog nyob ntawm qhov sib piv ntawm lub iav thiab qhov ua haujlwm zoo npaum li cas, uas yog zoo li DC lub cev muaj zog tswj.
Yuav ua li cas mus cuag DC lub cev muaj zog tswj?
Sinbaddrives, uas tau nruab nrog kev sib xyaw ceev tswj, sib haum xeeb ntawm qhov zoo ntawm DC motors nrog cov khoom siv hluav taws xob zoo. Cov kev txwv ntawm tus maub los thiab hom kev khiav hauj lwm tuaj yeem raug kho kom zoo siv tus tswj xyuas cov lus tsa suab. Nyob ntawm seb qhov xav tau ceev npaum li cas, txoj haujlwm rotor tuaj yeem taug qab digitally lossis nrog xaiv muaj cov analog Hall sensors. Qhov no tso cai rau kev teeb tsa ntawm kev tswj ceev ceev nrog rau tus tswj hwm kev txav chaw thiab cov programming adapters. Rau cov tshuab hluav taws xob micro, ntau yam DC lub cev muaj zog tswj tau muaj nyob rau hauv kev ua lag luam, uas tuaj yeem kho lub cev muaj zog raws li cov khoom siv hluav taws xob. Cov no suav nrog cov qauv xws li 12V DC lub cev muaj zog ceev, 24V DC lub cev muaj zog ceev, thiab 6V DC lub cev muaj zog ceev tswj.
2. Tswj ceev nrog voltage
Fais motors encompass ib tug ntau yam spectrum, los ntawm fractional horsepower qauv haum rau cov khoom me me mus rau high-power units nrog ntau txhiab horsepower rau hnyav industrial ua hauj lwm. Kev ua haujlwm ceev ntawm lub tshuab hluav taws xob yog cuam tshuam los ntawm nws tus qauv tsim thiab qhov zaus ntawm qhov siv hluav taws xob. Thaum load yog nyob tas li, lub cev muaj zog ceev yog ncaj qha proportional rau cov khoom voltage. Yog li ntawd, qhov txo qis hauv qhov hluav taws xob yuav ua rau txo qis hauv lub cev muaj zog. Cov kws tsim hluav taws xob txiav txim siab qhov tsim nyog lub cev muaj zog raws li cov kev xav tau tshwj xeeb ntawm txhua daim ntawv thov, piv rau kev qhia cov horsepower nyob rau hauv kev sib raug zoo rau cov neeg kho tshuab load.
3. Tswj ceev nrog Armature Voltage
Txoj kev no yog tshwj xeeb rau cov motors me. Lub teb winding tau txais lub zog los ntawm qhov chaw tas mus li, thaum lub armature winding yog powered los ntawm ib qho kev sib txawv, sib txawv DC qhov chaw. Los ntawm kev tswj lub armature voltage, koj tuaj yeem kho lub cev muaj zog ceev los ntawm kev hloov lub armature tsis kam, uas cuam tshuam qhov voltage poob thoob plaws armature. Ib tug sib txawv resistor yog siv nyob rau hauv series nrog armature rau lub hom phiaj no. Thaum qhov sib txawv ntawm cov resistor nyob ntawm nws qhov chaw qis tshaj plaws, qhov kev tiv thaiv armature yog qhov qub, thiab lub armature voltage txo. Raws li qhov kev tiv thaiv nce, qhov hluav taws xob thoob plaws lub armature txuas ntxiv, ua kom lub cev muaj zog thiab ua kom nws nrawm dua li qib qub. Txawm li cas los xij, qhov teeb meem tseem ceeb ntawm txoj kev no yog qhov tseem ceeb ntawm lub zog poob los ntawm cov resistor nyob rau hauv series nrog armature.
4. Tswj ceev nrog Flux
Txoj kev no modulates cov sib nqus flux generated los ntawm lub teb windings los tswj qhov ceev ntawm lub cev muaj zog. Qhov sib nqus flux yog txuas ntxiv raws li qhov tam sim no dhau los ntawm qhov chaw winding, uas tuaj yeem hloov kho los ntawm kev kho qhov tam sim no. Qhov kev hloov kho no yog ua tiav los ntawm kev sib xyaw ua ke ntawm qhov sib txawv ntawm cov resistor nyob rau hauv series nrog lub teb winding resistor. Thaum xub thawj, nrog rau qhov sib txawv ntawm cov resistor ntawm nws qhov tsawg kawg nkaus qhov chaw, cov ntsuas tam sim no ntws los ntawm qhov chaw winding vim qhov ntsuas qhov ntsuas hluav taws xob, yog li txhawb nqa qhov nrawm. Raws li qhov kev tiv thaiv tau nce zuj zus, tam sim no los ntawm lub tshav pob winding intensifies, uas ua rau ib tug augmented flux thiab ib tug tom qab txo nyob rau hauv lub cev muaj zog ceev hauv qab nws tus qauv tus nqi. Thaum txoj kev no siv tau rau DC lub cev muaj zog tswj ceev, nws tuaj yeem cuam tshuam cov txheej txheem kev sib hloov.

Cov txheej txheem peb tau saib tsuas yog ib txoj hauv kev los tswj qhov ceev ntawm DC lub cev muaj zog. Los ntawm kev xav txog lawv, nws yog qhov tseeb zoo nkauj tias ntxiv micro gearbox los ua tus tswj lub cev muaj zog thiab xaiv lub cev muaj zog nrog cov khoom siv hluav taws xob zoo meej yog qhov ntse tiag tiag thiab kev siv nyiaj txiag.
