Kunezinhlobo eziningi motors kagesi, njenge ama-stepper, noma ama-stepper motors, futhi ama-servomotor. Ngaphakathi kokugcina kunamamodeli athakazelisa ngempela, anjengokuthi Icala le-Servo SG90. I-servo engase ilungele amaphrojekthi okuqala, imikhuba nalolu hlobo lwedivayisi, ukufunda, ukulawula amarobhothi okulula, njll. Futhi, izidingo zayo zamandla ziphansi kakhulu, zinganikwa amandla kusuka ku-a ipuleti le-adrien noma kusuka embobeni ye-USB ye-PC kuye ku-5v.
Iyini i-Micro Servo SG90?
I-servo ye-SG90 iyi-servo encane, nabanye izilinganiso ezihlangene kakhulu ukukwazi ukuhlanganisa kumaphrojekthi lapho indawo ibalulekile. Ngaphezu kwalokho, iyonga futhi kulula ukuyisebenzisa, enesidingo esiphansi kakhulu samandla, ngakho-ke kungenzeka futhi ukuyisebenzisela ku-embedded, i-IoT noma ezinye izinhlelo zokusebenza ezisetshenziswa kancane.
Ngokuqondene ne-Servo SG90, le moto ye-servo ihlanganisa a isixhumi sohlobo lwendawo yonke S ezokwazi ukungena kumishini eminingi yokuhweba. Yakhiwe ngezintambo ezi-3 ezinemibala ekhomba ukuthi ngayinye isetshenziselwa ini:
- I-Rojo: intambo yamandla ephozithivu noma i-Vcc (+)
- UBrown: ingabe ikhebuli yamandla inegethivu (-) noma i-GND (ephansi)
- I-Naranja: yikhebula eliphethe isignali ye-PPM (Pulse Position Modulation) ukuze ulawule i-servomotor
Amanye amamodeli angase futhi abe nokwakheka kombala Okumnyama-Obomvu-Mhlophe, lapho isikimu kuleli cala kuzoba Isiginali ye-GND-Vcc-PPM ngokulandelanayo.
Izici ze-SG90 Servo
Kepha izici zobuchwepheshe kule servomotor, i-Servo SG90 igqama kulokhu:
- isisindo esisekelwe: phakathi kuka-1.2 no-1.6 Kg (eyanele ngosayizi wayo omncane)
- I-torque ye-motor ku-4.8vIsisindo: 1.2kg/cm
- I-voltage yokusebenza: 4 – 7.2v
- Isivinini se-spin ku-4.8v: 0.12s/60º
- i-engeli yokujikelezaawu :120
- I-Rango de temperatura de funcionamientoUkushisa: -30ºC kanye +60ºC
- Ubukhulu: 22 × 11.5 × 27 mm
- Isisindo: 9 g noma 10.6 g kufaka phakathi ikhebuli nesixhumi
- I-Arduino-iyahambisana: yebo
- isixhumi sendawo yonke: iyahambisana nezamukeli eziningi zokulawula umsakazo (Futaba, JR, GWS, Cirrus, Hitec,…)
Uzothola futhi ezinye izinhlobo ze-Servo SG90, njengo:
- I-MG90S: Ifana ne-SG90, kodwa inamagiya ensimbi nokuxhumanisa, ngakho ingakwazi ukusekela kufika ku-1.8kg.
- I-MG996R: Inosayizi omkhudlwana, kodwa ingakwazi ukusekela kufika ku-15 Kg uma idliwe ku-6V, noma i-13 Kg uma idliwe ku-4.8v.

Ungathenga kuphi imodeli ye-servo motor efana nalena ngentengo ephansi
Uma ufuna ukuthenga i-servomotor ye-Servo SG90 yalolu hlobo, ungayithola ezitolo ezikhethekile ze-electronics noma endaweni yesikhulumi se-Amazon. Ngokwesibonelo, le mikhiqizo enconyiwe:
Njengoba ubona, Zishibhile kakhulu, futhi ungawathenga ekhululekile noma emaphaketheni amarobhothi namanye amaphrojekthi lapho udinga khona okungaphezu kweyodwa. Ngaphezu kwalokho, amanye amaphakethe afaka izesekeli ezithile ezengeziwe, njengama-blades, izikulufu, njll.
Kepha okuhlukile okushiwo ngenhla, unalezi:
Manje, uma okufunayo kuyilokhu i-servo motor enamandla kakhulu futhi eqinile, ekwazi ukukwazi ukumelana nemithwalo emikhulu kanye netorque enkulu, khona-ke uzoba neminye futhi eminyene kodwa enokusebenza okuphezulu:
- I-Quimat servo enamagiya ensimbi futhi isekela isisindo esingafika ku-20 Kg
- I-Servo Innovateking ekwazi ukusekela kufika ku-35 Kg womthwalo ku-eksisi yayo
- I-ANNIMOS servo enamagiya ensimbi engagqwali akwazi ukusekela kufika ku-60 Kg
- Ayikho imikhiqizo etholakele.
Ungayisebenzisa kanjani nge-Arduino
Ukunikeza isibonelo somdwebo we-Arduino IDE ukuze uqale ukuqonda ukuthi i-SG90 Servos isebenza kanjani, nali icala elingokoqobo. Kodwa okokuqala, ake sibone ukuthi kufanele xhuma i-servo ebhodini lakho le-Arduino:
- I-VDC: Kufanele ixhunywe kugesi wangaphandle noma kusixhumi esingu-5V se-Arduino. Uma uzosebenzisa izinsiza zikagesi ezimbalwa, khumbula njalo ukubeka phansi noma i-GND ngokufanayo ukuze ugweme izinkinga.
- I-GND: Ungakwazi ukuyixhuma ku-GND yebhodi le-Arduino.
- Isignali ye-PPM: ingaya kunoma yimaphi amaphinikhodi e-PWM ku-Arduino. Isibonelo, ukuya ku-D11 kumdwebo wethu.
Ukubona isibonelo sekhodi yomthombo, ongazama futhi ulungise ngokuthanda kwakho, unezibonelo zakho zombili ongazibona ku-IDE ngazo umtapo wezincwadi we-Servo.h, njengalena enye:
#include <Servo.h>
Servo myservo; //Crear el objeto servo
int pos = 0; //Posición inicial del servo SG90
void setup() {
myservo.attach(11); //Vincular el pin 11 de Arduino al control del Servo SG90
}
void loop() {
//Cambia la posición de 0º a 180º, en intervalos de 25ms
for (pos = 0; pos <= 180; pos += 1)
{
myservo.write(pos);
delay(25);
}
//Vuelve desde 180º a 0º, con esperas de 25ms
for (pos = 180; pos >= 0; pos -= 1)
{
myservo.write(pos);
delay(25);
}
}
