Taw qhia
Tus tsav tsheb hauv lub cev muaj zog yog hais txog cov khoom ntawm lub cev muaj zog uas yog lub luag haujlwm rau kev tsim cov kev sib hloov. Muab qhov yooj yim, tus tsav tsheb yog qhov ua rau lub cev muaj zog. Hauv tsab xov xwm no, peb yuav delve tob rau hauv kev ua haujlwm ntawm tus tsav tsheb hauv lub cev muaj zog, tshawb txog nws ntau hom, lawv qhov sib txawv thiab kev siv. Peb tseem yuav tham txog qee yam teeb meem ntsig txog tus neeg tsav tsheb thiab yuav ua li cas txo lawv.
Hom Tsav Tsheb
Muaj ntau hom kev tsav tsheb uas siv hauv cov motors. Hom tsav tsheb siv nyob ntawm seb lub cev muaj zog daim ntawv thov, ceev, thiab lub zog xav tau. Cov hauv qab no yog qee qhov sib txawv ntawm cov tsav tsheb uas feem ntau siv hauv cov motors-
Brushless DC Tsav Tsheb
Brushless DC (BLDC) cov tsav tsheb yog ib hom kev tsav tsheb uas nrov tshaj plaws siv nyob rau hauv motors niaj hnub no. Lawv nyiam rau lawv cov kev ua tau zoo, kev ntseeg siab, thiab kev saib xyuas tsis tshua muaj. BLDC lub cev muaj zog ua haujlwm ntawm DC voltage, feem ntau yog li ntawm 12VDC txog 48VDC.
Tus qauv ntawm tus tsav tsheb BLDC suav nrog lub rotor, stator, thiab cov teebmeem hauv tsev. Lub rotor yog qhov txav ntawm lub cev muaj zog, thaum lub stator yog qhov chaw nres tsheb. Lub Hall-effect sensors yog siv los xyuas qhov chaw ntawm lub rotor thiab tswj kev sib hloov ntawm lub cev muaj zog.
BLDC motors feem ntau yog siv rau hauv kev ua haujlwm siab xws li robotics, hluav taws xob tsheb, thiab drones.
Brushed DC Tsav Tsheb
Brushed DC (BDC) tsav tsheb yog lwm hom tsav tsheb. Tsis zoo li BLDC cov neeg tsav tsheb, lawv xav tau cov txhuam hniav - ib hom kev sib txuas ntawm cov hlua, kom xa cov tam sim no los ntawm lub zog xa mus rau lub rotor.
Cov txhuam hniav ua rau kev sib cuag nrog lub commutator, tso cai rau kev hloov pauv ntawm hluav taws xob hluav taws xob rau hauv lub zog siv tshuab. BDC motors tsis tshua muaj txiaj ntsig zoo dua li BLDC motors thiab xav tau kev saib xyuas ntau dua vim qhov hnav thiab tsim kua muag ntawm cov txhuam hniav.
BDC motors feem ntau yog siv rau hauv cov ntawv siv hluav taws xob tsawg xws li cov khoom ua si thiab cov khoom siv hauv tsev me.
AC Drivers
Alternating tam sim no (AC) tsav tsheb yog siv los tswj qhov ceev ntawm AC motors. Cov neeg tsav tsheb AC siv kev sib xyaw ua ke ntawm kev hloov pauv zaus thiab kev hloov pauv hluav taws xob kom sib txawv ntawm qhov ceev ntawm lub cev muaj zog.
AC tsav tsheb yog dav siv nyob rau hauv kev lag luam daim ntawv thov uas ceev tswj yog ib qho tseem ceeb, xws li conveyor siv thiab twj tso kua mis.
Stepper Tsav Tsheb
Stepper tsav tsheb yog ib hom tsav tsheb siv los tswj kev txav ntawm stepper motors. Stepper motors yog tsim los txav me me, cov kauj ruam meej, ua rau lawv zoo tagnrho rau cov ntawv thov uas xav tau qhov tseeb.
Stepper tsav tsheb ua haujlwm los ntawm kev xa cov pulses ntawm tam sim no mus rau lub cev muaj zog windings, yog li tswj kev sib hloov ntawm lub cev muaj zog. Stepper tsav tsheb feem ntau yog siv nyob rau hauv 3D tshuab luam ntawv, CNC tshuab, thiab robotic caj npab.
Servo Tsav Tsheb
Servo tsav tsheb yog siv los tswj servo motors. Servo motors yog tsim los tswj lub kaum ntse ntse lossis txoj haujlwm, ua rau lawv zoo tagnrho rau cov ntawv thov uas xav tau qhov tseeb hauv kev tswj cov lus tsa suab.
Cov neeg tsav tsheb servo ua haujlwm los ntawm kev tau txais ib txoj haujlwm hais kom ua teeb liab los ntawm tus maub los thiab kho lub cev muaj zog txoj hauj lwm raws li. Servo motors feem ntau yog siv nyob rau hauv robotics, RC tsheb, thiab industrial automation.
Common Driver-related Issues
Txawm hais tias cov tsav tsheb yog ib feem tseem ceeb ntawm lub cev muaj zog, lawv kuj muaj ntau yam teeb meem. Qee qhov teeb meem cuam tshuam txog kev tsav tsheb muaj xws li-
Kub kub
Overheating yog ib qho ntawm cov teeb meem feem ntau ntawm cov neeg tsav tsheb. Overheating tuaj yeem ua rau muaj kev puas tsuaj rau tus tsav tsheb thiab lwm yam khoom ntawm lub cev muaj zog. Overheating tuaj yeem tshwm sim los ntawm kev ua kom txias tsis txaus lossis kev thauj khoom ntau dhau.
Txhawm rau txo cov teeb meem overheating, cov tsav tsheb yuav tsum tau tsim nrog cov txheej txheem txias kom zoo hauv siab. Tsis tas li ntawd, cov neeg tsav tsheb yuav tsum raug ntsuas los tswj cov khoom uas lawv raug.
Electromagnetic cuam tshuam (EMI)
EMI yog lwm qhov teeb meem ntsig txog kev tsav tsheb. EMI tshwm sim thaum lub tshuab hluav taws xob electromagnetic cuam tshuam nrog lwm cov khoom siv hluav taws xob, ua rau cov teeb liab poob thiab cov ntaub ntawv tsis raug cai.
Txhawm rau txo cov teeb meem EMI, cov tsav tsheb yuav tsum tau tsim nrog kev tiv thaiv thiab kev lim dej kom zoo. Tsis tas li ntawd, cov cuab yeej hauv av yuav tsum ua kom raug.
Voltage Spikes
Voltage spikes tshwm sim thaum muaj qhov nce tam sim ntawm qhov hluav taws xob hauv qhov system. Voltage spikes tuaj yeem ua rau muaj kev puas tsuaj rau tus tsav tsheb thiab lwm yam khoom ntawm lub cev muaj zog, ua rau lub cev tsis ua haujlwm.
Yuav kom txo tau qhov voltage spikes, tsav tsheb yuav tsum tau tsim nrog voltage spike tiv thaiv circuits. Tsis tas li ntawd, voltage regulators yuav tsum tau siv los xyuas kom meej lub zog ruaj khov.
Xaus
Hauv kev xaus, tus tsav tsheb yog ib qho tseem ceeb ntawm lub cev muaj zog. Hom tsav tsheb siv nyob ntawm seb lub cev muaj zog daim ntawv thov, ceev, thiab lub zog xav tau. Cov tsav tsheb sib txawv suav nrog BLDC tsav tsheb, BDC tsav tsheb, AC tsav tsheb, tsav tsheb kauj vab, thiab tsav tsheb servo. Overheating, EMI, thiab voltage spikes yog qee yam teeb meem ntsig txog tus neeg tsav tsheb. Cov teeb meem no tuaj yeem txo tau los ntawm kev tsim tus tsav tsheb nrog cov txheej txheem txias kom zoo hauv siab, siv cov hluav taws xob tiv thaiv hluav taws xob tiv thaiv hluav taws xob, thiab ua kom lub zog ruaj khov.
