Hedzino nzira shoma dzekutyaira brushless DC mota.Zvimwe zvakakosha system zvinodiwa zvakanyorwa pazasi:
a.Magetsi transistors: Aya anowanzo MOSFET uye IGBTs anokwanisa kushingirira yakakwira voltages (inofananidzwa nezvinodiwa neinjini).Midziyo mizhinji yemumba inoshandisa mota dzinoburitsa 3/8 horsepower (1HP = 734 W).Naizvozvo, yakajairika inoshandiswa ikozvino kukosha ndeye 10A.High-voltage systems kazhinji (> 350 V) inoshandisa IGBTs.
b.MOSFET/IGBT mutyairi: Kazhinji kutaura, ndiye mutyairi weboka reMOSFET kana IGBT.Ndiko kuti, vatatu "half-bridge" vatyairi kana vatatu-phase vatyairi vanogona kusarudzwa.Mhinduro idzi dzinofanirwa kukwanisa kubata iyo yekumashure electromotive force (EMF) kubva mumotikari inopeta kaviri magetsi emota.Pamusoro pezvo, madhiraivha aya anofanirwa kupa dziviriro yemagetsi transistors kuburikidza nenguva uye switch control, kuve nechokwadi chekuti iyo yepamusoro transistor yakadzimwa isati yabatidzwa yepasi transistor.
c.Feedback chinhu / kutonga: Mainjiniya anofanirwa kugadzira imwe mhando yemhinduro chinhu mune servo control system.Mienzaniso inosanganisira optical sensors, Hall effect sensors, tachometers, uye yakaderera mutengo sensorless back EMF sensing.Nzira dzakasiyana-siyana dzemhinduro dzinobatsira zvikuru, zvichienderana nekururama kunodiwa, kukurumidza, torque.Zvishandiso zvakawanda zvevatengi zvinowanzotsvaga kushandisa kumashure EMF sensorless tekinoroji.
d.Analog-to-digital converter: Muzviitiko zvakawanda, kuitira kuti uchinje chiratidzo cheanalog kuchiratidzo chedhijitari, analog-to-digital converter inoda kugadzirwa, iyo inogona kutumira chiratidzo chedhijitari kune microcontroller system.
e.Single-chip microcomputer: Yese yakavharwa-loop control system (inenge yese brushless DC motors yakavharwa-loop control system) inoda imwe-chip microcomputer, iyo inotarisira servo loop control kuverenga, kugadzirisa PID kutonga uye sensor manejimendi.Aya madhijitari edhijitari anowanzo 16-bit, asi mashoma akaomarara anogona kushandisa 8-bit controllers.
Analog Power/Regulator/Reference.Pamusoro pezvikamu zviri pamusoro apa, masisitimu mazhinji ane magetsi emagetsi, magetsi anochinja, uye mamwe maturusi eanalog senge monitors, LDOs, DC-to-DC converters, uye mashandiro amplifiers.
