![]() Hook up the wires directly up to your microproc and burn it up with the following code: If you're not already tooled up for microprocessor programming, you could do worse than the Ghetto Development Kit or any of the various PIC programmers. Maybe you could use this to sense rotation in the Red-White-Blue coil when the Black-Yellow coil is being driven.) It's like it's half-bipolar, half-unipolar. ![]() ![]() (This motor's strange and doesn't have a center tap on the top magnet coil. You can see that White is the ground for the bottom trio b/c it has half the resistance to Red or Blue that they have to each other. Pictured is my notes from hooking up wires to wires and noting the resistance (or if they're connected at all). You can tell which is ground in a bipolar motor because it has half the resistance to either of the poles than the poles do across themselves. What you're looking for is the common (ground) wire for each half. ![]() ![]() If you've got a unipolar motor, or more than 4 wires, you're going to have to break out your ohmeter. All you have to do is figure out which two pairs of wires go together. If you're only looking at four wires, you're in luck - it's a bipolar motor. Your motor's going to have two halves, and you can probably even tell just by looking which side each wire belongs to. So you've got five (or four, or six) wires. ![]()
