Help To Understand Motor Wiring

by c0rtex on Tue Feb 18, 2014 2:48 pm

Hi Community,
So the last month or so I've really gotten into using Arduino; I'm new at this.

I've wired up a step motor before and worked fine, but to be honest I didn't really understand what I was doing and I now sorta regret that.

I needed a larger one for the project I am doing. So I have a unipolar with 6 leads. I understand the fundamentals of how the motor works and I have a data sheet that identifies the wires. ... YGH420.PDF

I just got the Arduino motor shield in and I know that I can run this motor on it. Pulled this quote from somewhere but I'm not sure what shorting the common wires means.
"Short common A to common B, connect common wires to + power, then A+,A-,B+,B- to unipolar driver"

In the meantime, I'm reading up on the Arduino motor shield to get a better understanding on connections.

Thanks for helping.

EDIT: I think what my resarch is getting at is that I can connect yellow/white wires to the ground and should function.

Check the resource links on this page for tips on figuring out how your motor is wired. In a unipolar motor, the 'common' wires are the center-taps of the coils.
