FDK J58A832T Stepper Motor

FDK J58A832T is a stepper motor from FDK Corporation, Japan. This model is obsolete now and not manufactured anymore. I bought this stepper motor from my near by electronic shop. I was troubled. It had no specification. Even the suppply voltage was not given. Only written thing I found on that was "FDK J58A832T". With this name I googled for data sheet, but it didn't gave me any thing. Finally I found a discussion on this motor in a forum, from where I got some details.


This is basically a 12 V Unipolar stepper motor with a stepping angle of 7.5 degrees. There are six wires (red-red-black-brown-orange-yellow). The two red wires (one from top coil and one from bottom coil) can be connected together to form a common connection and can be given to a 12V supply. Rest of the wires form the sequence. The stepping sequence is as follows.

For clockwise stepping

1000     (yellow)
0100     (black)
0010     (orange)
0001     (brown)

and repeat.

For anti-clockwise stepping 

0001     (brown)
0010     (orange)
0100     (black)
1000     (yellow)

and repeat.

i bought j58a850t,do you have any idea of its ratings and torque?

I don't have much details on it. Supply voltage is 12v and the step angle is 7.5 degrees and I used this for my final year project and is working quite fine. But no idea about torque. I just used it for rotating the camera on my rover.

hye @Anil C S , mind to email me your final year project details as my reference. I'm doin a project about this motor too. for microstepping control.

thanks.

send to nerdaia@yahoo.com

really appreciate that.
