Matla a ho khanna a brushless motor ke afe?

Mona ke litsela tse 'maloa tsa ho khanna brushless DC motor.Litlhokahalo tse ling tsa mantlha tsa sistimi li thathamisitsoe ka tlase:

a.Li-transistors tsa motlakase: Hangata ke li-MOSFET le li-IGBT tse khonang ho mamella maqhubu a phahameng (a tsamaellanang le litlhoko tsa enjine).Lisebelisoa tse ngata tsa lapeng li sebelisa li-motor tse hlahisang 3/8 horsepower (1HP = 734 W).Ka hona, boleng bo tloaelehileng bo sebelisoang hona joale ke 10A.Sistimi ea matla a phahameng hangata (> 350 V) e sebelisa li-IGBT.

b.Mokhanni oa MOSFET/IGBT: Ka kakaretso, ke mokhanni oa sehlopha sa MOSFET kapa IGBT.Ke hore, bakhanni ba bararo ba "half-bridge" kapa bakhanni ba mekhahlelo e meraro ba ka khethoa.Litharollo tsena li tlameha ho khona ho sebetsana le matla a morao a electromotive (EMF) ho tsoa ho enjene e habeli matla a motlakase.Ho feta moo, bakhanni bana ba lokela ho fana ka tšireletso ea li-transistor tsa matla ka ho laola nako le ho laola, ho etsa bonnete ba hore transistor e ka holimo e tingoa pele transistor e ka tlaase e buloa.

c.Karolo ea maikutlo / taolo: Baenjiniere ba lokela ho rala mofuta o itseng oa karolo ea maikutlo tsamaisong ea taolo ea servo.Mehlala e kenyelletsa li-sensor tsa optical, li-sensor tsa Hall effect, li-tachometers, le li-sensor tsa morao tsa EMF tse theko e tlaase ka ho fetisisa.Mekhoa e fapaneng ea maikutlo e molemo haholo, ho itšetlehile ka ho nepahala ho hlokahalang, lebelo, torque.Lisebelisoa tse ngata tsa bareki hangata li batla ho sebelisa theknoloji ea morao-rao ea EMF.

d.Analog-to-digital converter: Maemong a mangata, e le hore u fetole letšoao la analog ho letšoao la digital, mochine oa analog-to-digital o hloka ho etsoa, ​​​​o ka romelang letšoao la digital ho microcontroller system.

e.Single-chip microcomputer: Litsamaiso tsohle tse koetsoeng tse koetsoeng (hoo e batlang e le li-motors tsa DC tse se nang brushless ke litsamaiso tsa taolo tse koetsoeng) li hloka microcomputer e le 'ngoe, e ikarabellang bakeng sa lipalo tsa taolo ea servo loop, taolo ea PID ea ho lokisa le taolo ea sensor.Li-controller tsena tsa dijithale hangata li na le 16-bit, empa lits'ebetso tse sa rarahaneng haholo li ka sebelisa li-control tsa 8-bit.

Analog Power/Regulator/Reference.Ntle le likarolo tse kaholimo, litsamaiso tse ngata li na le lisebelisoa tsa motlakase, li-voltage regulator, li-voltage converters, le lisebelisoa tse ling tsa analog tse kang limonita, li-LDO, li-converter tsa DC-to-DC, le li-amplifiers tse sebetsang.

Analog Power Supplies/Regulators/References: Ho phaella ho likarolo tse ka holimo, litsamaiso tse ngata li na le lisebelisoa tsa motlakase, li-voltage regulator, li-voltage converters, le lisebelisoa tse ling tsa analog tse kang li-monitor, LDO, li-converter tsa DC-to-DC, le li-amplifiers tse sebetsang.
