Tsav Txoj Cai ntawm Coreless Motors

Coreless motors siv lub coreless rotor qauv thiab hluav taws xob commutation (BLDC) thev naus laus zis los hloov hluav taws xob ncaj qha mus rau hauv lub zog siv tshuab, ua tiav kev ua haujlwm siab.

1. Core Drive System Cheebtsam

Coreless motors feem ntau muaj cov hlau nplaum ruaj khov stator, coreless rotor, ib qho kev sib hloov, thiab txoj hauj lwm sensors. Lub rotor siv tus qauv tsim, feem ntau yog ua los ntawm enameled hlau braided rau hauv lub khob- zoo li tus qauv. Lub stator siv siab -cov khoom siv hlau nplaum ruaj khov xws li neodymium hlau boron (NdFeB).

2. Txoj Cai Kev Ua Haujlwm Hauv Hluav Taws Xob

Tus tsav tswj xyuas lub rotor txoj hauj lwm siv Hall effect sensors los yog rov qab EMF, meej meej tswj cov energizing ib ntus thiab sij hawm ntawm peb -theem windings. Ib txoj hauv kev rau - kauj ruam commutation (120℃conduction mode) los yog FOC vector tswj algorithm yog siv los ua kom muaj qhov sib nqus tsis tu ncua uas tsav lub rotor.

3. Cov yam ntxwv tseem ceeb ntawm kev ua haujlwm

- Pib Torque: 3-5 npaug ntawm qhov ntsuas torque ntawm qhov ntsuas hluav taws xob

- Kev nrawm nrawm: feem ntau 8000-50000 RPM (nyob ntawm qhov loj thiab tsim)

- Chav Kawm Ua Haujlwm: Txog li 90% lossis siab dua (cov qauv hlau- cov tub ntxhais kawm feem ntau yog 70-85%)

- Lub Sijhawm Teb:<10ms (5-8 times faster than iron-core motors)

4. Kev Tswj Xyuas Tsav Tsheb

Yuav tsum muaj lub siab tsav nti (xws li DRV11873, MC33035) lossis microcontroller tov, siv PWM ceev tswj. Kev khiav hauj lwm voltage feem ntau yog 3.7V-24V, thiab tam sim no txawv ntawm 0.5A txog 20A nyob ntawm qhov loj me. Kev tiv thaiv overcurrent thiab ntsuas kub ntsuas hluav taws xob yog qhov yuav tsum tau ua.

Precautions: Hollow-cup motors may experience axial movement at high speeds (>30000 RPM), xav tau qhov sib ntxiv ntawm lub caij nplooj ntoos hlav preload lossis sib nqus qhov chaw. Lub voj voog tsav yuav tsum raug tiv thaiv electromagnetically kom tsis txhob muaj siab - zaus cuam tshuam los ntawm kev tswj tsis tau.
