It is a BIG stepping motor, so you have to generate wave pulsed DC for each of the three sets of poles,in sequence.

thanks for your late input pixie. but google already told me otherwise

well pyro, i must say well done. Thats some crazy looking shit right there, you are gonna have to post a video of it running when youre finnished.

When you started this thread, i didnt think you were gonna acheive anything other than passing 440V through yourself to earth. Now im sure ya can do it and im cheering you on. (unless acc rings me, then i warned you)

Thanks mate. all we need now is 3 relay's for the motor and another 3 for the water input / output.

and sorry pixie I think i might of been a bit harsh. but I still doubt it was a stepping DC motor since all three coil array's ended up connecting to each other at the end. but I DO admit that is IS possible that I was wrong, although unlikely.

I have had to modify the coil array's to handle a DC stepping motor input.

No offence taken.
I still think you will find that it is a big stepping motor.
Any stepping motor will act as a three phase alternator when it is driven.
Why don't you get one of the stepping motor driver kits from Jaycar or DSE,beef up the outputs with MOSFETs and drive your washing machine off your computer?

at this moment I have removed the end of the coil's link so they are no longer connected to each other and replaced it with 3 sets of wires. with 3 relay's and a timing circuit (which has already been built)

we have built a serial port interface (minus 3 tiny relay's) to test the speed of the circuit so we can ensure its running on time on all 3 coil array's

the test relay's should be purchased in the next couple of days so we can test it and assuming that goes well, the bigger relay's will be purchased after that.

the thing is this washing machine is being rebuilt at next to no cost since we want to make a hack job out of it and to show people that 'no user servicable parts inside' is a load of bollocks.

oh and btw it WILL eventually be running of a Compaq Proliant server for diagnostics, fine tuning and a web interface with data reporting not to mention the voice recognition..... but you already knew that huh.... cos you read the thread.... huh....

edit: by thread I meant the 'more info' link on the first post. sorry.
