wondering if any of you guys know the wiring setup. There is 2 groups of 3 wires, which makes up the 2 coils inside. Anyone know which wires are for which coil? I am trying to hook it up to a Haltech E6K and this is my main issue at the moment.

 

All I know is that I need to ignore completey the centre tap wire for each coil and connect the Haltech to the end wires.

 

cheers, Wes.

Hi,

 

The first thing to determine is the pairing. If you have a multimeter, measure the resistance across pairs of wires. That will tell you which three go together. Now look at the resistance across these three in pairs; one reading will show twice the resistance of the other two combinations. That high resistance pair are your end wires.

 

As for which set of wires is clockwise and which is counterclockwise, hook it all up to the Haltek and it'll be pretty clear if you have them backwards.

 

Hope that helps.

 

Reards,

I posted in this thread earlier but deleted my post until I had a chance to take a closer look.

 

Six-wire stepper motors are of the unipolar variety.

Basically power is supplied to the tap in the center of the winding and the ends of the winding are alternately grounded (via transistors) to move the motor through discrete magnetic steps, allowing precise positioning.

 

Four-wire stepper motors are of the bipolar variety.

A bipolar, or h-bridge style driver is typically used to supply current of alternating polarity to the windings, accomplishing the same goal as a unipolar motor.

 

Page 82 of the following document states that only bipolar (4-wire) steppers should be used.

I think it may be possible to use a bipolar driver circuit to power a unipolar motor by using only the low-side FETs and supplying power to the center of the winding, but doing so would require the Haltech's hardware and firmware to support it, and I'm pretty sure it does not. This may also be a bad idea for other electrical reasons that I am not familiar with, such as back EMF.

 

On page 82 it also says that you can contact Haltech for suitable bipolar steppers.

 

Best of luck,
