Kako koristiti Mosfet Optocoupled HW-532 za kontrolu brzine DC motora do 30V ili opterećenja koristeći Arduino
Ovaj projektni vodič pokazuje kako izgraditi svestrani regulator brzine DC motora koristeći Arduino i HW-532 optokaplirani MOSFET modul. MOSFET može biti FR120N, LR7843 ili D4184. Ovo vam omogućava kontrolu brzine i uključenog/isključenog stanja DC motora s naponima do 30V. HW-532 modul nudi zaštitu i izolaciju, čineći ga sigurnijim i pouzdanijim od direktnog povezivanja motora na Arduino.

Ovaj projekt je vrijedan za različite primjene. Evo nekoliko primjera:
- Precizno kontroliranje brzine robotske ruke
- Izgradnja ventilatora s promjenjivom brzinom za rashladne sisteme
- Kreiranje automatiziranih mašina s podesivim kretanjem
- Razvijanje motorizirane kontrole ventila za fluidne sisteme
Hardver/Komponente
Osnovne komponente su Arduino, HW-532 optokaplirani MOSFET modul (s MOSFET opcijama poput D4184, LR7843 ili FR120N), DC motor (naponska vrijednost ≤ 30V), spojne žice, te opcionalno potenciometar i tipkalo za naprednu kontrolu (u videu na 19:34).
Izbor MOSFET-a unutar HW-532 modula ovisi o vašim strujnim zahtjevima (u videu na 01:24). Video pruža detaljno poređenje različitih MOSFET-ova (u videu na 06:50) i njihove prikladnosti za različite primjene (u videu na 09:45). Zapamtite uključiti diodu za induktivna opterećenja poput DC motora kako biste zaštitili modul (u videu na 06:00 i 22:02).
Vodič za povezivanje
Osnovno povezivanje spaja pozitivni terminal motora na izlaz HW-532, negativni terminal motora na masu HW-532, a kontrolni pin HW-532 na digitalni pin Arduina (u videu na 11:16).

Objašnjenje koda
Priloženi kod nudi tri nivoa kontrole:

- Kontrola uključeno/isključeno: Ovaj jednostavni kod (u videu na 15:05) koristi digitalni pin za uključivanje i isključivanje motora. Korisnički podesivi dio je konstanta
MOTOR_OUT_PIN, koja definira koji Arduino pin kontrolira HW-532 modul. - PWM kontrola brzine: Ovaj kod (u videu na 15:39) koristi Pulse Width Modulation (PWM) za kontrolu brzine motora. Korisnik može podesiti
SPEED_MAXiSPEED_MINza postavljanje gornjih i donjih granica kontrole brzine, a funkcijemotorControl()istopMotor()koriste se za kontrolu motora i njegovo zaustavljanje, respektivno. - Kontrola potenciometrom i tipkalom: Ovaj kod (u videu na 22:12) omogućava kontrolu brzine motora potenciometrom i pokretanje/zaustavljanje tipkalom. Korisnički podesivi dijelovi uključuju
POT_PIN(pin potenciometra),MOTOR_OUT_PIN(PWM kontrolni pin),START_STOP_PIN(pin tipkala),SPEED_MAXiSPEED_MIN.
Živi projekt/Demonstracija
Video demonstrira rad sva tri primjera koda. Kontrola uključeno/isključeno prikazana je (u videu na 11:41), zatim PWM kontrola brzine (u videu na 16:53), i na kraju kontrola potenciometrom i tipkalom (u videu na 23:02).
