Bet way to control m49sp_2k motor

Hi all, i have a Mitsumi motor m49sp_2k and arduino mega, i would like to control the motor at 1 rpm. I have ULN 2803, 2003, arduino motor shiled and L293. What is the best controller for this motor?

Thank in advance..

none of those.

One like this may be overkill Control current and hold-force with switches. (see its datasheet)

and this cheap, useful. current control via simple pot. (Easy to kill. ny students 'eats' them)

If i wnat use this motor with arduino motor shield or L293@12 VDC is not possible?

Post a link to the datasheet for your motor. Without that I have no idea what you need.

You may find someuseful stuff in stepper motor basics. An L293 is a very poor choice for driving a stepper motor.

The speed of a stepper is entirely governed by how fast (or slow) the step pulses are produced.


Edit to add link - apologies for omission.

The motor is the same of my first post and i dont need of full tourqe. I want use Motor shiled v3, i uncutted Vin and i used Vin +Gnd screw connector but dosent work with stepper library.

#include <Stepper.h>

const int stepsPerRevolution = 48;  // change this to fit the number of steps per revolution
                          // for your motor

// initialize the stepper library on the motor shield
Stepper myStepper(stepsPerRevolution, 12,13);     

// give the motor control pins names:
const int pwmA = 3;
const int pwmB = 11;
const int brakeA = 9;
const int brakeB = 8;
const int dirA = 12;
const int dirB = 13;

int x = 0;
void setup() {
// set the PWM and brake pins so that the direction pins  // can be used to control the motor:
pinMode(pwmA, OUTPUT);
pinMode(pwmB, OUTPUT);
pinMode(brakeA, OUTPUT);
pinMode(brakeB, OUTPUT);
digitalWrite(pwmA, HIGH);
digitalWrite(pwmB, HIGH);
digitalWrite(brakeA, LOW);
digitalWrite(brakeB, LOW);

// initialize the serial port:
// set the motor speed (for multiple steps only):

void loop() {

Its a low impedance bipolar stepper motor, you use a chopper driver like the A4988 to drive
it since it needs current control.

It is not voltage controlled like a DC motor.

I forgot to to put the link to stepper motor basics in Reply #3 - apologies.

I have now corrected it.
