Camtronics driver questions

[HomeCNC]

A servo system is not cheap. You would need new drives and power supply as well as new motors. You would be talking over $1000 for all the electronics.

Why don't you get one of these motors to test with your setup. If it works then you can get two more.

Jeff,

I looked up the torque of the motors I have and they are rated at 77 to 116 oz/in.

The one you suggested at 187 oz/in is about 60% more.

Will consider giving it a try.

With the powermax motors there is usually two ways you can wire the plug at the motor end (that is if it is not a flying lead type). One is a series configuration the other is a parallel configuration, you will get much more out of them if you wire them in the parallel configuration. I you look up the powermax cattledog it will show you both ways of doing it, we had a similar problem and changing the config fixed it for us. Also grabbing the shaft to stop the motors is easy in most cases when you are testing the torque, the best way to test the mechanical advantage/motor power is to set the axis moving and try pushing the end of the table in the opposite direction.

We have dans stuff and are happy with it.

Thanks Dave,

I'm not quite sure how the motors are hooked up...but will see if that makes a difference.

No Probs,

If you can't find the specs you need I can fax them to you as we use these motors all the time for our cnc retrofits. Just pm me your fax no.

Hi Kb
the powermax steppers with the flying leads
how are they wired in series or parallel?
thanks
rob

Rob,

I will look it up for you, I'll get back to you as soon as I can, I will have to find out what colors correspond to what pins in the plug type that we get in, once I get that info I will email you a diagram.

I will keep in touch.

I just verified with Dan that you can run higher voltages on that board if you run a seperate 5v supply.
I intend to run 24v and Dan said it was possible, but you'd require a larger heat sink...........Jim

Thanks Jimini....will look into that.

In the meantime, I added a 3 to 1 gear train, and the torque has increased quite a bit, where I can't stop the leadscrews with my hand anymore.
