hi i have a shinano kenshi 2.1v 1.65am have 8 wires
red white blue green orange brown blk yellow trying 2 hook
up 2 my sp-3 drive and can firgure out which wire it hook
up to the terminal help please thanx you
Your going to have to create a 5/6 wire configuration out of the wires you have. First of all, you have to pair them out (I looked quick and did not find any wire schem. for that model, I assume you have done so as well). Four pairs will become obvious as soon as you use your meter to pair them out. 4 wires become the center tap (+) on FET - The other 4 wires become step and direction. Here comes the fun part. It is sort of a poke and hope unless you find specs on the motors, or have meters to find out which phase your dealing with. I use a dual terminal block set up and just change wires till I find the correct combo. I am sure some of the electrical guru's can offer up some better ways of doing this, but for me, I sit down with a nice cold beer and try all the different wire combos till I hit on the one that works. Good Luck!
it try me crazy couldn't find anything on the web about shinano
kenshi motor i try all the combination all i got it got the motor
shaking. how do you test with the meter, i not a electronic guy
Have you paired them out? Use a meter and you should come up with 4 pairs. That will get you started. Then I usually break it down with some hope that Black / White Red / Green and Br / Yellow will be a phase. Then try combos from there. In the Gecko White pages there is a section that explains how to arrive at which ones are in phase, or hope some of the wire nuts chime in here and help.
I will do some more looking around. I was able to solve my delema when I finally found the documentation on my motors, and low and behold, I had done it right, go figure.
Okay, an 8 wire motor can be used in either bipolor or unipolor mode. I assume you understand which configuration your driver requires. Given that, it is quite easy to determine which wire pairs operate each of the 4 coils. You should be able to figure it out before you finish a beer... All you need is an ohm meter. Start by check for resistence by selecting one wire and finding another wire that shows some resistence (it won't be much, probably in the 5 to 20 ohm range). You have just found a pair. Repeat process with remaining wires until you have 4 pairs (they should all have equal resistence). Now the fun part. And I won't try to explain it all but will direct you to a web page that does a good job of showing you how to get the right sequence by using your driver. Its worked for me.
I forgot to mention, but I think others have that most 8 wire motors have some striped wires. These will help you keep polarity straight for the pairs. Also, if you are using a unipolor configuration, check out the other tutorials at this site. I found them very helpful.
ok i use the meter and i got 4 pair red yellow black white
blue green orange brown. i hook it up for my unipolar drive
green/yellow/brown/white to the terminal abcd and the orther
4 to v+ make it 5 wire , i got the motor turning but rough
it viberate. my problem is i dont know which wire is v+
anysugestion thanx you
Okay, I'm not sure why you chose the colors you did to connect to V+. If it was because they all had a stripe on them, then thats great. If not, and they were chose at random, you could be having a polarity problem. If a wire pair is reversed for which one connects to v+ then opposing coils in the motor will work against each other rather than together. Sometimes you can use a 9v battery to charge each pair and determine which direction it trys to turn the motor (this can be a bit tricky and you almost have to be holding the shaft to feel the slight step direction).
The other problem you might be having if the polarity is okay is the hook up order to your driver. If ABCD on the board are hooked to the wrong color, the motor will just vibrate. If this is the case, check the web links I posted in the earlier replies to figure out the right order.
I have a question not unlike the original but different I guess. I have some steppers with 9 yes 9 wires and I have no wire diagrams or any idea where to find them. The motors I have are american precision industries model number M343-07S. Any ideas? Any way I have no idea where to even start with these maybe you guys know where i can get more info.
I have seen some documentation for 9 wire motors. I think you will end up with 4 pairs and one common to center tap. But I am guessing and will look and see if I can find something on them later on. Also, look for things like all pairs consisting of a solid and stripe, then stripes are most likely center tap. Good Luck.
also, look at Bills posts, you might be able to use a battery to further your cause.
