Servo Motor ndi Drive Selection Mfundo Zofunikira

I. Core Motor Selection

Katundu Analysis

1. Kufanana kwa Inertia: Katundu inertia JL iyenera kukhala ≤3 × motor inertia JM. Kwa makina olondola kwambiri (monga ma robotics), JL/JM<5:1 kuti mupewe kugwedezeka.
2. Zofunikira za Torque: Torque Yopitilira: ≤80% ya torque yomwe idavotera (imalepheretsa kutenthedwa) Torque Pamwamba: Imakwirira magawo othamangitsa / kuchepetsa (mwachitsanzo, 3 × torque).
3. Kuthamanga Kwambiri: Liwiro loyezedwa liyenera kupitirira liwiro lenileni ndi 20% -30% malire (mwachitsanzo, 3000 RPM → ≤2400 RPM).

Mitundu Yagalimoto

1. Permanent Magnet Synchronous Motor (PMSM): Chosankha chachikulu chokhala ndi mphamvu zambiri (30% -50% apamwamba kuposa ma induction motors), abwino kwa maloboti.
2. Induction Servo Motor: Kukana kutentha kwambiri komanso mtengo wotsika, woyenera ntchito zolemetsa (mwachitsanzo, ma cranes).

Encoder ndi Ndemanga

1. Kusamvana: 17-bit (131,072 PPR) pazantchito zambiri; Kuyika kwa nanometer kumafuna 23-bit (8,388,608 PPR).
2. Mitundu: Mtheradi (chikumbukiro cha malo pakuzimitsa), chowonjezera (chimafunika homing), kapena maginito (anti-interference).

Kusinthasintha Kwachilengedwe

1. Mulingo wa Chitetezo: IP65+ pamalo akunja/fumbi (monga ma mota a AGV).
2. Kutentha Kusiyanasiyana: Industrial-grade: -20 ° C mpaka + 60 ° C; apadera: -40°C mpaka +85°C.

II. Zofunika Zosankha Zoyendetsa

Kugwirizana kwagalimoto

1. Zofananira Zamakono: Kuyendetsa movoteledwa pano ≥ mota yovotera pano (mwachitsanzo, 10A mota → ≥12A drive).
2. Kugwirizana kwa Voltage: voteji ya basi ya DC iyenera kuyanjanitsa (mwachitsanzo, 400V AC → ~ 700V DC basi).
3. Kuchepa kwa Mphamvu: Mphamvu yoyendetsa galimoto iyenera kupitirira mphamvu ya injini ndi 20% -30% (pazolemetsa zosakhalitsa).

Control Modes

1. Mitundu: Malo / liwiro / torque modes; Kulunzanitsa kwamitundu yambiri kumafuna giya yamagetsi/cam.
2. Protocols: EtherCAT (low latency), Profinet (industrial-grade).

Dynamic Performance

1. Bandwidth: Bandwidth ya loop panopa ≥1 kHz (≥3 kHz pa ntchito zazikulu).
2. Kutha Kuchulukira: Kukhazikika kwa 150% -300% torque (mwachitsanzo, maloboti ophatikizika).

Mawonekedwe a Chitetezo

1. Ma Brake Resistors: Amafunika poyambira / kuyimitsa pafupipafupi kapena kunyamula katundu wambiri (mwachitsanzo, ma elevator).
2. Mapangidwe a EMC: Zosefera zophatikizika / zotchingira zokana phokoso la mafakitale.

III. Kukhathamiritsa Kogwirizana

Kusintha kwa Inertia

1. Gwiritsani ntchito ma gearbox kuti muchepetse chiŵerengero cha inertia (mwachitsanzo, gearbox ya mapulaneti 10:1 → inertia ratio 0.3).
2. Direct drive (DD motor) imachotsa zolakwika zamakina kuti zikhale zolondola kwambiri.

Zochitika Zapadera

1. Katundu Woyima: Ma mota okhala ndi mabuleki (mwachitsanzo, ma elevator traction) + kulunzanitsa siginecha ya brake (mwachitsanzo, chizindikiro cha SON).
2. Kulondola Kwambiri: Ma aligorivimu ophatikizika (<5 μm cholakwika) ndi kubweza kwa mikangano.

IV. Kusankhidwa kwa Ntchito

1. Zofunikira: Tanthauzirani torque ya katundu, kuthamanga kwambiri, kulondola kwa malo, ndi njira yolumikizirana.
2. Kuyerekezera: Tsimikizirani kuyankha kwamphamvu (MATLAB/Simulink) ndi kukhazikika kwamafuta podzaza.
3. Kuyesa: Sinthani magawo a PID ndikubaya phokoso kuti mutsimikizire kulimba.

Chidule cha nkhaniyi: Kusankhidwa kwa Servo kumayika patsogolo mphamvu zonyamula katundu, magwiridwe antchito, komanso kulimba kwa chilengedwe. ZONCN servo motor and drive kit imakupulumutsirani vuto losankha ka 2, ingoganizirani za Torque, Peak RPM, ndi Precision.
