Yintoni amandla okuqhuba i-brushless motor?

Nazi iindlela ezimbalwa zokuqhuba i-brushless DC motor.Ezinye iimfuno zenkqubo esisiseko zidweliswe ngezantsi:

a.Ii-transistors zamandla: Ezi zidla ngokuba zii-MOSFET kunye nee-IGBTs ezikwaziyo ukumelana nombane ophezulu (ohambelana neemfuno zenjini).Uninzi lwezixhobo zasekhaya zisebenzisa iimotor ezivelisa i-3/8 horsepower (1HP = 734 W).Ngoko ke, ixabiso eliqhelekileyo elisetyenziswayo langoku ngu-10A.Iisistim zombane ophezulu ziqhele (> 350 V) zisebenzisa ii-IGBTs.

b.Umqhubi we-MOSFET/IGBT: Ngokuqhelekileyo, ngumqhubi weqela le-MOSFET okanye i-IGBT.Oko kukuthi, abaqhubi abathathu "i-half-bridge" okanye abaqhubi besigaba sesithathu banokukhethwa.Ezi zisombululo kufuneka zikwazi ukuphatha amandla e-electromotive angasemva (EMF) ukusuka kwimotor ephinda kabini umbane wemoto.Ukongezelela, aba baqhubi kufuneka banikeze ukukhuselwa kwee-transistors zamandla ngokusebenzisa ixesha kunye nolawulo lokutshintsha, ukuqinisekisa ukuba i-transistor ephezulu ivaliwe ngaphambi kokuba i-transistor ephantsi ivulwe.

c.Ingxelo/ulawulo: Iinjineli kufuneka ziyile uhlobo oluthile lwengxelo kwinkqubo yolawulo lwe-servo.Imizekelo ibandakanya i-optical sensors, i-Hall effect sensors, i-tachometers, kunye nexabiso eliphantsi le-EMF le-sensorless back sensing.Iindlela ezahlukeneyo zeempendulo ziluncedo kakhulu, kuxhomekeke ekuchanekeni okufunekayo, isantya, i-torque.Usetyenziso oluninzi lwabathengi lufuna ukusebenzisa itekhnoloji ye-EMF engevayo.

d.I-analog-to-digital converter: Kwiimeko ezininzi, ukwenzela ukuguqula isignali ye-analog kwisignali yedijithali, i-analog-to-digital converter idinga ukuyilwa, enokuthumela umqondiso wedijithali kwi-microcontroller system.

e.I-microcomputer ye-Single-chip: Zonke iinkqubo zokulawula i-loop evaliweyo (phantse zonke ii-motor ze-DC ezivaliweyo ziyinkqubo yokulawula i-loop evaliweyo) zifuna i-microcomputer ye-single-chip, ejongene nezibalo zokulawula i-servo loop, ukulungiswa kwe-PID yokulawula kunye nokulawula inzwa.Aba balawuli bedijithali badla ngokuba yi-16-bit, kodwa izicelo ezincinci ezinobunzima zingasebenzisa abalawuli be-8-bit.

Amandla e-Analog/uMlawuli/iReferensi.Ukongeza kula macandelo angasentla, iinkqubo ezininzi ziqulethe izixhobo zombane, izilawuli zombane, iziguquli zombane, kunye nezinye izixhobo ze-analog ezifana ne-monitor, ii-LDO, ii-DC-to-DC converters, kunye ne-amplifiers esebenzayo.

I-Analog Power Supplies/Regulators/References: Ukongeza kula macandelo angasentla, iinkqubo ezininzi ziqulethe izixhobo zombane, izilawuli zombane, ii-voltage converters, kunye nezinye izixhobo ze-analog ezifana ne-monitor, ii-LDO, i-DC-to-DC converters, kunye ne-amplifiers yokusebenza.
