ステッピングモーター( PM35S-048 )をArduinoで動かしてみた。

360時計回りに回転して、その後360逆時計回りするようにしてみた。

I took apart my old Brothers MFC 420CN Print / Scan / Fax machine.
Found a PM35s048 stepper motor. 
The data sheet shows it as having 48 steps (7.5 degree).

I just hooked it up with the following:

Yellow = Digital 4
Orange = Digital 5
Red = Digital 6
Black = Digital 7

I modified the example code for a stepper motor (MotorKnob) to 
have the required 48 steps and increased the speed a bit. 
As well I mapped the potentiometer values to 0-48 instead of using the default 0-1023. 
Makes for a single rotation and a lot less noise.

#include <Stepper.h>

//How many steps does your motor have
#define STEPS 48

//Start new Stepper class with 48 steps (STEPS defined above) 
//Motor is connected to pins 4, 5, 6 & 7
Stepper stepper(STEPS, 4, 5, 6, 7);

//Create starting position for motor / pot
int previous = 0;

void setup()
{
  //How fast will we try to move the motor
  //If your motor stutters, its too fast so just lower the value
  stepper.setSpeed(180);
}

int _speed = 10;
void loop()
{
  for (int i=0;i<48;i++) {
    stepper.step(1);
    delay(_speed);
  }
  for (int i=48;i>0;i--) {
    stepper.step(-1);
    delay(_speed);
  }
}

赤：V+(5V)
茶：6
黒：7
橙：4
黄：5

感想：
トルクは結構弱いが、角度の精度はかなり高く使いやすそうな印象でした。

追記：
本来の駆動電圧は24Vらしい！
