thank for the answer. one more question since i am a bit confused as i am not very familiar with stepping motors. i measuerd the coils and the resistance is near 30 ohms so far so good. from an older datasheet i have it says its a unipolar motor and i need a fifth pin for the 12v supply but there is no fifth pin. does this mean that the motor is a bipolar stepper motor? aslo i noticed that the excitation method is a 2-2 phase unipolar driver. so do i need a unipolar driver or a bipolar?
Hello , I've just registered on this site ...i have several MITSUMI stepper motor ...and I'm searching for a simple controller and how to connect to the circuit...
Please help...THANKS..........
Presumably the motor was connected to the circuit board in the printer, follow the traces from the connector on the circuit board and most of them will connect to an IC.
Make a not of the number of the IC and look up its datasheet.
I recently did something like this with a stepper motor from a flatbed scanner.
Once I had identified the motor driver and understood the datasheet, I cut off the corner of the circuit board with the IC and wired it up to my PIC development board.
Now, study the datasheet for the mtd2003 and have a look at the typical applications (if there are any) and compare with what is on the printer circuit board.
If you are lucky, you will be able to cut the section of the board which has the mtd2003 and associated components and use that for your experiments rather than having to create the motor driver from scratch.
