Lipotso Tse Leshome Tsa Bohlokoa Mabapi le Taolo ea makoloi

Theknoloji ea taolo ea likoloi e bohareng ba liindasteri, likoloi tsa motlakase, lisebelisoa tsa lapeng tse bohlale, le tse ling. Bakeng sa baenjiniere le ba chesehelang theknoloji ka ho tšoanang, ho bohlokoa ho utloisisa melao-motheo le liphephetso tsa eona.

Potso ea 1: Sepheo sa mantlha sa taolo ea makoloi ke sefe?

Moko oa taolo ea enjene ke ho laola motlakase, hona joale, kapa maqhubu ho fihlela tlhahiso e lakatsehang ka lebelo, torque kapa boemo. Lipheo tsa bohlokoa li kenyelletsa:

• Karabelo e nepahetseng haholo(mohlala, taolo e kopaneng ea liroboto tsa indasteri)

• Ts'ebetso e sebetsang hantle ea matla(mohlala, ho ntlafatsa tšebeliso ea matla ho li-EVs)

• Ho hana tšitiso e matla(mohlala, ho tsitsisa li-drones maemong a moea)

Potso ea 2: Ke hobane'ng ha taolo e koetsoeng e hlokahala?

Taolo ea loop e bulehileng (mohlala, ho kenya motlakase ka kotloloho) e bonolo empa e na le phoso: liphetoho tsa tšohanyetso tsa mojaro kapa litšitiso tsa tikoloho li baka ho fetoha ha lebelo. Taolo ea loop e koetsoeng e sebelisa maikutlo a nako ea nnete (mohlala, matshwao a khouto) ho lokisa liphoso. Likopo li kenyelletsa:

• Sistimi ea servo e hlokang ho nepahala ha boemo ba ± 0.01mm

• Tsepamiso e nepahetseng ea mokato oa lifti

Potso ea 3: PWM e thusa joang ho laola lebelo le boreleli?

Pulse Width Modulation (PWM) e fetola motlakase o tloaelehileng ka ho tima/ho tima motlakase ka potlako. Ka mohlala:

• Potoloho ea 50% e fana ka 50% ea motlakase oa phepelo

• Maqhubu a ho fetoha a phahameng (mohlala, 20kHz) a fokotsa ho thothomela ha enjene
  Melemo: Litahlehelo tse tlase tsa potoloho, ho lumellana le balaoli ba dijithale (mohlala, li-MCU).

Potso ea 4: Ke hobane'ng ha taolo ea vector (FOC) e sebetsa hantle?

Mekhoa ea setso (mohlala, taolo ea V / F) e hlokomoloha ho kopanya pakeng tsa matla a khoheli le torque. Field-Oriented Control (FOC) e arola tsena ka ho sebelisa li-coordinate transformation (Clarke-Park transforms), e arola maqhubu a mekhahlelo e meraro hore e be.thoholetsoletorquedikarolo. Sena se etsisa katleho ea makoloi a DC, se eketsa ts'ebetso ka 15% (mohlala, ka li-compressor tsa AC tse feto-fetohang).

Potso ea 5: Taolo e se nang kutlo e hakanya boemo ba rotor joang?

Ho sebelisoa mekhoa e se nang kutlobashebelli ba morao-EMFkapaente e phahameng ea maqhubuho fana ka boemo ba rotor, e loketseng maemo a sa tsotelleng litšenyehelo kapa a ts'epahalang haholo:

• Drone ESCs (ho qoba liphoso tsa sensor)

• Bafani ba malapa (ho fokotsa litšenyehelo tsa hardware)
  Khoebo: Ts'ebetso e fokolang e fokolang ha e bapisoa le mekhoa e thehiloeng ho sensor.

Potso ea 6: Hobaneng ha motlakase o qala ho phahama hona joale?

Ha e ntse e eme, morao-EMF ke zero, e bakang "rotor e notletsoeng" (5-7 × rated current). Litharollo li kenyelletsa:

• Li-circuits tse qalang tse bonolo(keketseho ea motlakase butle-butle)

• Star-delta switching(ho fokotsa motlakase oa pele)

Potso ea 7: Mokhoa oa ho hatella ho thothomela le lerata joang?

Lisosa tse tloaelehileng li kenyelletsa resonance ea mochini le li-harmonics tsa motlakase. Mekhoa ea ho fokotsa:

• Khatello ea Harmonic (mohlala, SVPWM e nang le maqhubu a feto-fetohang)

• Ho qoba libaka tsa resonance (ka frequency scanning)

• Li-algorithms tse sebetsang tsa damping (mohlala, taolo ea ponelopele ea mohlala)

Potso ea 8: Hobaneng taolo ea mocheso e le bohlokoa?

Litahlehelo tsa makoloi (koporo, tšepe) li hlahisa mocheso, ho beha kotsi ea demagnetization ea ka ho sa feleng kapa ho senyeha ha insulation. Lintlha tsa moralo:

• Li-sensor tsa mocheso (mohlala, li-thermistor tsa NTC) bakeng sa tlhahlobo ea nako ea nnete

• Sistimi ea ho futhumatsa (ho pholisa moea / metsi, liphaephe tsa mocheso)

Potso ea 9: Mokhoa oa ho khetha li-motor control chips?

• Li-MCU: Bakeng sa mesebetsi e sa rarahanang haholo (mohlala, letoto la STM32)

• DSPs: Khokahano ea lebelo le holimo (mohlala, TI C2000)

• FPGAs: Litlhoko tsa morao-rao tse tlase haholo (mohlala, litsamaiso tsa likoloi tse ngata)

Potso ea 10: Ke eng e latelang bakeng sa theknoloji ea taolo ea makoloi?

• Khokahano ea AI: Marang-rang a Neural a nkela tokiso ea PID ea matsoho

• Lisebelisoa tsa SiC: Ho ntlafatsa ts'ebetso ea ho fetoha ha maemo a holimo

• Mafahla a dijithale: Ho potlakisa nts'etsopele ka prototyping ea sebele
