Ha ho bapisoa le koloi ea DC le asynchronous motor, litšobotsi tsa bohlokoa tsa tekheniki ea Brushless DC motor ke:

1.Litšobotsi tse sebetsang tsa motlakase oa DC li fumanoa ka taolo ea elektronike. E na le taolo e ntle le mefuta e mengata ea lebelo.

Boitsebiso ba maikutlo a boemo ba 2.Rotor le mokhanni oa motlakase oa multiphase inverter lia hlokahala.

3. Ha e le hantle, motlakase oa AC o ka sebetsa ka lebelo le phahameng ntle le tlhase le ho phunyeha ha borashe le mopalami. E na le ts'epo e phahameng, nako e telele ea ho sebetsa 'me ha e hloke tlhokomelo.

4.Brushless DC motor e na le matla a maholo, ha ho tahlehelo ea rotor le mocheso, le ts'ebetso e phahameng: ha e bapisoa le data, katleho ea 7.5 kW asynchronous motor ke 86.4%, 'me katleho ea matla a tšoanang le brushless DC motor e ka fihla ho 92.4% .

5.Ho tlameha ho ba le likarolo tsa taolo ea elektroniki, litšenyehelo tsohle li phahame ho feta koloi ea DC.

Haholo-holo ho na le mefuta e 'meli ea li-motor tse sebelisoang tsamaisong ea AC: motor induction le magnet synchronous motor. Permanent magnet synchronous motor e ka aroloa ka sinusoidal back EMF permanent magnet synchronous motor (PMSM) le square wave back EMF brushless DC motor (BLDCM) ho latela molao-motheo o fapaneng oa ho sebetsa. E le hore mokhoa oa bona oa ho khanna oa hona joale le oa ho laola o fapane.

EMF e ka morao ea sinusoidal permanent magnet synchronous motor ke sinusoidal. E le hore enjene e hlahise torque e boreleli, motlakase o phallang ka har'a moea oa motlakase o tlameha ho ba sinusoidal. Ka hona, lets'oao le tsoelang pele la boemo ba rotor le tlameha ho tsejoa, 'me inverter e ka fana ka motlakase oa sinusoidal kapa hona joale ho enjene. Ka hona, PMSM e hloka ho amohela motlakase o phahameng kapa oa hona joale. Qeto ea "encoder" kapa "encoder" ea boemo le eona e thata haholo.

BLDCM ha e hloke sensor ea boemo bo phahameng, sesebelisoa sa maikutlo se bonolo, 'me algorithm ea taolo e batla e le bonolo. Ho phaella moo, lekhalo la moea la magnetic field la BLDCM trapezoidal wave le sebetsa hantle ho feta la PMSM sinusoidal wave, 'me matla a matla a BLDCM a phahame ho feta a PMSM. Ka hona, ts'ebeliso le lipatlisiso tsa motlakase oa magnet brushless DC li fumane tlhokomelo e eketsehileng.
