Nov yog ob peb txoj hauv kev los tsav lub brushless DC lub cev muaj zog.Qee qhov yuav tsum tau ua hauv qhov system tau teev tseg hauv qab no:

ib.Fais fab transistors: Cov no feem ntau yog MOSFETs thiab IGBTs muaj peev xwm tiv taus siab voltages (raws li lub cav yuav tsum).Cov khoom siv hauv tsev feem ntau siv cov motors uas tsim 3/8 horsepower (1HP = 734 W).Yog li, tus nqi tam sim no siv tau yog 10A.High-voltage systems feem ntau (> 350 V) siv IGBTs.

b.MOSFET / IGBT tsav tsheb: Feem ntau hais lus, nws yog tus tsav tsheb ntawm ib pawg MOSFET lossis IGBT.Ntawd yog, peb tus tsav tsheb "ib nrab choj" lossis tus tsav tsheb peb theem tuaj yeem xaiv tau.Cov kev daws teeb meem no yuav tsum muaj peev xwm tswj tau lub zog rov qab electromotive force (EMF) los ntawm lub cev muaj zog uas yog ob npaug ntawm lub cev muaj zog.Tsis tas li ntawd, cov tsav tsheb no yuav tsum tau muab kev tiv thaiv ntawm lub hwj chim transistors los ntawm lub sijhawm thiab kev hloov pauv, kom ntseeg tau tias lub transistor sab saum toj raug muab tua ua ntej lub hauv qab transistor qhib.

c.Cov ntsiab lus tawm tswv yim / tswj: Cov kws ua haujlwm yuav tsum tsim qee yam kev tawm tswv yim hauv servo tswj qhov system.Piv txwv xws li optical sensors, Hall effect sensors, tachometers, thiab qis tshaj tus nqi sensorless rov qab EMF sensing.Ntau txoj kev tawm tswv yim muaj txiaj ntsig zoo, nyob ntawm qhov xav tau qhov tseeb, nrawm, torque.Ntau cov neeg siv khoom siv feem ntau nrhiav kev siv rov qab EMF sensorless thev naus laus zis.

d.Analog-rau-digital converter: Muaj ntau zaus, txhawm rau hloov lub teeb liab analog rau lub teeb liab digital, yuav tsum tau tsim lub analog-rau-digital converter, uas tuaj yeem xa cov teeb liab digital mus rau microcontroller system.

e.Single-chip microcomputer: Tag nrho cov kaw-voj tswj tshuab (yuav luag txhua lub tshuab tsis siv lub tshuab DC yog kaw-lub voj tswj tshuab) yuav tsum muaj ib lub tshuab microcomputer, uas yog lub luag haujlwm rau servo voj tswj kev suav, kho PID tswj thiab kev tswj xyuas sensor.Cov maub los digital no feem ntau yog 16-ntsis, tab sis cov ntawv siv tsawg dua tuaj yeem siv 8-ntsis controllers.

Analog Fais Fab/Regulator/Reference.Ntxiv rau cov khoom siv saum toj no, ntau lub tshuab muaj cov khoom siv hluav taws xob, hluav taws xob tswj hluav taws xob, hluav taws xob hloov hluav taws xob, thiab lwm yam khoom siv analog xws li saib, LDOs, DC-rau-DC converters, thiab cov khoom siv ua haujlwm.

Analog Power Supplies/Regulators/References: Ntxiv rau cov khoom siv saum toj no, ntau lub tshuab muaj cov khoom siv hluav taws xob, hluav taws xob tswj hluav taws xob, hluav taws xob hloov hluav taws xob, thiab lwm yam khoom siv analog xws li saib, LDOs, DC-rau-DC converters, thiab ua haujlwm amplifiers.
