Nka nkomoko yamashanyarazi yibikoresho byamashanyarazi cyangwa imashini zitandukanye, umurimo wingenzi wa moteri nugutera umuriro wumuriro.

Nubwo kugabanya umubumbe ukoreshwa cyane cyane hamwe na moteri ya servo na moteri yintambwe, ubumenyi bwumwuga bwa moteri buracyakunzwe cyane.Kubwibyo, sinihanganye kubona iyi "incamake yimikorere ikomeye ya moteri mumateka".Garuka gusangira nabantu bose.

Brushless Direct Motor Motor (BLDCM) ikuraho amakosa asanzwe ya moteri ya DC yasunitswe kandi igasimbuza moteri ya moteri hamwe na moteri ya elegitoroniki.Kubwibyo, brushless itaziguye moteri ifite moteri nziza ihindagurika nibindi biranga moteri ya DC.Ifite kandi ibyiza byuburyo bworoshye bwitumanaho AC moteri, nta flame yo kugabanuka, imikorere yizewe no kuyitaho byoroshye.
Amahame shingiro no gutezimbere algorithms.

Amabwiriza agenga ibinyabiziga bya BLDC agenzura umwanya na sisitemu ya rotor ya moteri moteri ikura ikosora.Kugenzura igipimo gifunze-kugenzura igipimo, hariho amategeko abiri yinyongera, ni ukuvuga, gupima neza umuvuduko wa moteri ya moteri / cyangwa moteri ya moteri hamwe nikimenyetso cya PWM kugirango ugenzure ingufu zisohoka umuvuduko wa moteri.

Moteri ya BLDC irashobora guhitamo uruhande rukurikirana cyangwa ikigo cyubuyobozi kugirango bikurikirane ibimenyetso bya PWM ukurikije amabwiriza yo gusaba.Porogaramu nyinshi zihindura gusa ibikorwa nyirizina ku gipimo cyagenwe, kandi ibimenyetso 6 bitandukanye byo gutandukanya PWM bizatoranywa.Ibi birerekana ecran ntarengwa.Niba ukoresheje seriveri yihariye kugirango uhagarare neza, sisitemu yo gufata feri ikoresha ingufu cyangwa imbaraga zo guhindura ibintu, birasabwa cyane gukoresha ikigo cyuzuye cyuzuye kugirango ukurikirane ibimenyetso bya PWM.

Kugirango urusheho kunoza rotor igice cya moteri ya magnetiki induction, moteri ya BLDC ikoresha sensor ya Hall-effet kugirango yerekane induction ihagaze neza.Ibi bisubizo mubisabwa byinshi nibiciro biri hejuru.Inductorless BLDC imikorere ikuraho ibikenerwa bya Hall, kandi ihitamo gusa imbaraga zituruka kumashanyarazi (imbaraga za electromotive power) za moteri kugirango zitegure kandi zisesengure igice cya rotor ya moteri.Igikorwa cya Sensorless ningirakamaro cyane cyane kubiciro byigiciro gito cyo kugenzura nko gukonjesha abafana na pompe.Iyo ukoresheje moteri ya BLDC, firigo na compressor nabyo bigomba gukoreshwa nta inductor.Kwinjiza no kuzuza igihe cyuzuye cyumutwaro
Moteri nyinshi za BLDC ntizikeneye kuzuzanya kwa PWM, igihe cyuzuye cyo kwinjiza cyangwa kwishyurwa igihe cyose.Birashoboka cyane ko porogaramu ya BLDC hamwe nibi biranga ari moteri ikora cyane ya moteri ya servisi ya BLDC, sine-wave yashishikarije moteri ya BLDC, moteri yogejwe AC, cyangwa moteri ya PC.

Sisitemu nyinshi zitandukanye zo kugenzura zikoreshwa mukugaragaza manipulation ya moteri ya BLDC.Mubisanzwe, ingufu za transistor zisohoka zikoreshwa nkumurongo ugengwa nogutanga amashanyarazi kugirango ukoreshe imbaraga zumuriro wa moteri.Ubu bwoko bwuburyo ntabwo bworoshye gukoresha mugihe utwaye moteri ifite ingufu nyinshi.Moteri zifite ingufu nyinshi zigomba gukoreshwa na PWM, kandi microprocessor igomba gutomorwa kugirango yerekane ibikorwa byo gutangira no kugenzura.

Sisitemu yo kugenzura igomba kwerekana imirimo itatu ikurikira:

PWM ikora voltage ikoreshwa mugucunga umuvuduko wa moteri;

Sisitemu yakoreshejwe mu kugabanya moteri mu ikosora;

Koresha imbaraga zikora amashanyarazi cyangwa ibikoresho bya Hall kugirango uhanure kandi usesengure inzira ya rotor ya moteri.

Guhindura ubugari bwa pulse bikoreshwa gusa kugirango uhindure imbaraga zakazi zikora kuri moteri ihindagurika.Umuvuduko ukwiye wakazi ufitanye isano neza ninshingano za PWM.Iyo habonetse uburyo bukosora bwo gukosora, ibipimo bya torque biranga BLDC ni kimwe na moteri ya DC ikurikira.Impinduka zikoreshwa mumashanyarazi zirashobora gukoreshwa mugukoresha umuvuduko numuvuduko wa moteri.
