You can see the whole chip, but the upper part, with the white plastic connector for four wires has broken off.. Do you wire them all up similarly? JimboZA, that looks very useful. I think they are all essentially the same. Conversely, the max current of 1 Amp could be achieved with 4. Or do they vary wildly in the way you have to wire them up? There is no intelligence or logic inside the motor any more than there is in a regular DC motor – just coils and magnets.

Mitsumi M49SP-2K stepper motor.
Using Ohm’s law that would suggest a current, at 24V of 5. Two or three hours spent thinking and reading documentation solves most programming problems. I reckon you haven’t m9sp-2k at the Wikipedia article. Within the motor there are two separate electromagnet coils. There are only two separate circuits but they are wound as several coils.
Conversely, the max current of 1 Amp could be achieved with 4. Read times previous topic – next topic. JimboZA, that looks very useful.

Can some one point me in the direction of a good tutorial that explains how to use one of these. Effective current limiting with transistors or mosfets would be complex unless you are familiar with that sort of stuff. Robin2 on Oct 29, I salvaged it from a photocopier printer. As far as I know many stepper motors specify the voltage that gives the permitted current – in which case this would be described as a 4.
Johannesburg hams mitsuml me: The “logic” is provided by the Arduino and the stepper motor driver board. Wikipedia has a good explanation.

Unfortunately, the chip is broken, just above the 8 contact points. I think you have the wrong mental model. By energizing them in the right order the rotor which is a permanent magnet moves.
There is no intelligence or logic inside the motor any more than there is in a regular DC motor – just coils and magnets. Or do they vary wildly in the way you have to wire them up? Mitsumi M49SP-2K stepper motor. Robin2 Brattain Member Posts: However I would recommend the OP uses the A driver or some similar driver specifically for stepper motors rather than the L But you don’t connect the two “ground” wires together or the two power wires.
I think they are all essentially the same. The Pololu A driver may well be suitable and if you look that up you should see wiring details.
With four wires there is usually one pair for each coil – checking the resistance should be able to identify the pairs.
Can anyone tell me how to connect this 8 points to become 4 wires? It’s going to be hard to help if you keep the datasheet secret.
I know it is 24V and has 4 wires but I have the faintest idea how to wire it up with an arduino. I see nothing in the datasheet you provided to make me think there is anything unusual about the motor. Robin2 on Oct 30, You will need some mitumi of interface between the Arduino and the motor because the Arduino can’t supply enough current or 24V.

You can see the whole mitumi, but the upper part, with the white plastic connector for four wires has broken off. There are also several poles on the permanent magnet rotor. So, I am left with the 8 soldering points, instead of the usual 4 wires, that you can plug in.
