Servo Tsav thiab Tsav Xaiv Cov Ntsiab Lus Tseem Ceeb

I. Core Motor Selection

Load Analysis

1. Inertia Matching: Load inertia JL yuav tsum yog ≤3 × lub cev muaj zog inertia JM. Rau cov tshuab ua haujlwm siab (piv txwv li, neeg hlau), JL / JM <5: 1 kom tsis txhob oscillations.
2. Torque Requirements: Nruam Torque: ≤80% ntawm rated torque (tiv thaiv overheating). Peak Torque: Npog acceleration / deceleration theem (xws li, 3 × rated torque).
3. Kev nrawm nrawm: Rated ceev yuav tsum tshaj qhov siab tshaj plaws ceev nrog 20% ​​-30% npoo (piv txwv li, 3000 RPM → ≤2400 RPM).

Hom Tsav

1. Permanent Magnet Synchronous Tsav (PMSM): Mainstream xaiv nrog lub zog siab ceev (30% -50% siab dua induction motors), zoo tagnrho rau cov neeg hlau.
2. Induction Servo Tsav: Kub-kub kuj thiab tus nqi qis, tsim nyog rau kev siv hnyav (piv txwv li, cranes).

Encoder thiab Cov Lus Teb

1. Kev daws teeb meem: 17-ntsis (131,072 PPR) rau feem ntau cov haujlwm; nanometer-theem positioning yuav tsum tau 23-ntsis (8,388,608 PPR).
2. Hom: Tsis muaj (txoj haujlwm nco ntawm lub hwj chim tawm), nce ntxiv (yuav tsum muaj tsev), lossis sib nqus (tiv thaiv kev cuam tshuam).

Environmental Adaptability

1. Kev Tiv Thaiv Kev Ntsuas: IP65+ rau qhov chaw sab nraum zoov / plua plav (piv txwv li, AGV motors).
2. Qhov kub thiab txias: Muaj qib: -20 ° C txog + 60 ° C; Tshwj xeeb: -40 ° C rau + 85 ° C.

II. Drive Xaiv Qhov Tseem Ceeb

Tsav Compatibility

1. Kev sib txuam tam sim no: Tsav ntsuas tam sim no ≥ lub cev muaj zog ntsuas tam sim no (piv txwv li, 10A lub cev muaj zog → ≥12A tsav).
2. Voltage Compatibility: DC tsheb npav voltage yuav tsum ua raws (piv txwv li, 400V AC → ~ 700V DC tsheb npav).
3. Fais fab rov qab: Tsav lub zog yuav tsum tshaj lub cev muaj zog los ntawm 20% -30% (rau kev thauj mus los ntev).

Tswj hom

1. Hom: Txoj hauj lwm / ceev / torque hom; multi-axis synchronization yuav tsum tau hluav taws xob gearing / cam.
2. Cov kev cai: EtherCAT (tsis tshua muaj latency), Profinet (qib kev lag luam).

Dynamic Performance

1. Bandwidth: Tam sim no voj bandwidth ≥1 kHz (≥3 kHz rau high-dynamic ua hauj lwm).
2. Kev Muaj Peev Xwm Tshaj Tawm: Txhawb nqa 150% -300% rated torque (piv txwv li, palletizing neeg hlau).

Kev tiv thaiv nta

1. Nres Resistors: Yuav tsum tau nquag pib / nres lossis siab inertia loads (piv txwv li, elevators).
2. EMC Tsim: Integrated filters / shielding rau muaj suab nrov kuj.

III. Kev sib koom tes ua kom zoo

Kev kho inertia

1. Siv gearboxes kom txo qis inertia piv (xws li, planetary gearbox 10: 1 → inertia ratio 0.3).
2. Direct tsav (DD lub cev muaj zog) tshem tawm cov neeg kho tshuab yuam kev rau ultra-siab precision.

Cov xwm txheej tshwj xeeb

1. Vertical Loads: Nres-nruab motors (piv txwv li, elevator traction) + tsav nres teeb liab sync (piv txwv li, SON teeb liab).
2. High Precision: Hla-coupling algorithms ( <5 μm yuam kev) thiab kev sib txhuam kev them nyiaj.

IV. Xaiv Txoj Haujlwm

1. Yuav tsum tau: txhais lub load torque, ncov ceev, positioning raug, thiab kev sib txuas lus raws tu qauv.
2. Simulation: validate dynamic teb (MATLAB/Simulink) thiab thermal stability nyob rau hauv overload.
3. Kev Ntsuas: Kho qhov ntsuas PID thiab txhaj cov suab nrov rau kev kuaj xyuas qhov ruaj khov.

Cov ntsiab lus: Servo xaiv qhov tseem ceeb ntawm kev thauj khoom muaj zog, kev ua tau zoo, thiab kev tiv thaiv ib puag ncig. ZONCN servo lub cev muaj zog thiab cov khoom siv tsav txuag koj qhov teeb meem ntawm kev xaiv 2 zaug, tsuas yog xav txog Torque, Peak RPM, thiab Precision.
