Stepper info please...

[Coogrrr]

For you techno geeks I need a little more information on this stepper. It has 5 wires not 6 or 4 so I am confused on wiring it up. Also it is 7.5 degrees and 48 steps per revolution so maybe some mach3 setup info if you have it?

Here is a link to all its specs.

I have a PM55L and a PM35L and I think I have several more just need to check. These will be used for a foam cutting CNC so huge oz/in is not needed but I would like to know what they are rated at the math on that link is beyond my understanding.

OH yeah and the wires on these are all one color all black... and the connector faces up toward the back of the motor not left or right!!!!

Thanks in advance

The torque values are in Newton-meters or more specifically fractional Nm.

The PM35L range is .02-.0425 Nm or 2.83-6.0 Oz Inches
The PM55L range is .07-.12 Nm or 9.9-16.99 Oz Inches

More data for the motors is on the NMB website

You may be able to figure out which lead is which by checking the resistance of the leads or pinouts. Just use the plug data found in the floating dialog box in your link. #9. Drive circuitry gives some info on how the plug and coils are wired internally. 5 wires may be a clue to a uni-polar configuration wherein the center taps are common.

Hope that helps a little.
