为什么此代码不会运行我的bldc电机？

Question

我需要运行我的BLDC电机。我偶然发现了这个代码，它使我可以通过按下键盘上的数字来移动我的BLDC电机。通过此代码，我可以按下键盘编号并将电机设置为所需的转速。但我的电机似乎并没有运行。请告诉我这个问题，也许是为什么我的BLDC电机无法运行的建议。

下面是代码：

// include the library code: 
#include <LiquidCrystal.h> 
#include <EEPROM.h> 
#include <Keypad.h> 

const byte ROWS = 5; //four rows 
const byte COLS = 4; //four columns 
//define the cymbols on the buttons of the keypads 
char hexaKeys[ROWS][COLS] = { 
    {'1','2','3','A'}, 
    {'4','5','6','B'}, 
    {'7','8','9','C'}, 
    {'*','0','#','D'}, 
    {'*','0','#','D'} 
}; 
byte rowPins[ROWS] = {2, 3, 4, 5}; 
byte colPins[COLS] = {6, 7, 8, 9}; 
//initialize an instance of class NewKeypad 
Keypad customKeypad = Keypad(makeKeymap(hexaKeys), rowPins, colPins, ROWS, COLS); 

// initialize the library with the numbers of the interface pins 
LiquidCrystal lcd(A0, A1, A2, A3, A4, A5);

Answer 1

当你正在使用的Arduino，BLDC不会analogWrite功能，您必须使用servo.write(val) 功能BLSC运行。

#include <Servo.h> 

Servo myservo; // create servo object to control a servo 

pos = 50; 

void setup() 
{ 
    myservo.attach(9); // attaches the servo on D9 to the servo object 
} 

void loop() 
{ 
    // The min and max value is 0 and 180 
    //Change pos variable according to your requirement 
    myservo.write(pos);  
    delay(40); 
}
