Cov lus qhia no yuav qhia yuav ua li cas khiav DC Brushless lub cev muaj zog (coj los ntawm HDD) nrog H-Choj L298

Kauj Ruam 1: Siv Brushless Motor Los Ntawm HDD

Yuav Ua Li Cas Txhuam Txhuam Tsav
Yuav Ua Li Cas Txhuam Txhuam Tsav

Tshem tawm DC brushless lub cev muaj zog los ntawm HDD tawg. Lub cav no muaj 3 lub xov hlau tso tawm. Cov kauj ruam tom ntej yuav qhia tias nws ua haujlwm li cas

Kauj Ruam 2: Yuav Ua Li Cas Txhuam Txhuam Tsav

Lub cav tsis txhuam muaj qhov sib hloov (hu ua rotor) khiav yam tsis muaj kev sib cuag hluav taws xob. Qhov no yuav tso cai rau nws tuaj yeem khiav nrawm

Ib feem ntawm tus lej (hu ua stator) yuav ua rau lub tshuab nqus hlau tig tig tig rotor

Hauv theem 1, lub taub hau ntawm cov xim ntsuab yog (+) thiab cov xim xiav yog (-). Qhov sib npaug ntawm cov hlau nplaum ntawm ob lub kauj yuav ua rau tag nrho cov kev taw qhia sib nqus raws li hauv daim duab -> ua rotor tig mus rau qhov kev qhia no thiab nres ntawm no.

Tom ntej hauv theem 2, lub taub hau ntawm cov xim liab yog (+) thiab kauj xiav yog (-). Ib zaug ntxiv, tag nrho cov kev taw qhia sib nqus raws li hauv daim duab -> ua rotor tig qhov kev taw qhia no thiab nres ntawm no.

Ib zaug ntxiv hauv theem 3, 4, 5, 6, nws yuav ua rotor tig 1 lub voj voog.

Kauj Ruam 3: Tsav Tsheb Txhuam Txhuam

Tsav rau Brushless Tsav
Tsav rau Brushless Tsav

Peb khub ntawm tus tiv thaiv tau txuas nrog lub taub hau ntawm cov xim ntsuab, xiav, liab -> cov transistors yuav ON/OFF synchronized ua kom sib nqus teb tig (raws li hauv cov lus piav qhia saum toj no)

Kauj Ruam 4: Siv H-choj L298 rau Tsav Tsheb

Ib nrab ntawm H-choj tau siv ua 1 khub transistor.

Saib sab hauv L298 IC, nws muaj peev xwm ntws tam sim no los ntawm H-choj mus rau lwm H-choj

Kauj Ruam 5: Ua Circuit Court

Txuas H-choj rau lub cev muaj zog thiab Arduino (Pro Mini) raws li hauv daim duab

Nov yog kuv qhov txuas txuas

Kauj Ruam 6: Txoj Cai Ua Haujlwm

Txoj Cai Ua Haujlwm
Txoj Cai Ua Haujlwm

Txoj cai yuav siv tus qauv raws li hauv daim duab, uas yuav siv lub zog rau txhua lub kauj raws li hauv kauj ruam 2

Tag nrho cov cai rau Arduino nyob ntawm no (Google qhia tawm)
