If there is no encoder then it is just what has become a conventional

So if it is just a 4 wire step motor then it is a permanent magnet rotor?

Two things...
It used to mean that the motor had a permanent magnet rotor.
It now sometimes gets used to refer to a closed-loop step-servo, where

If you can't fix it, you don't own it.

5/16" or 8mm can be just fit in by milling out the nut channel in the
saddle as wide as possible while
Very nice. Especially hearing the spindle speed up as the tool moves inward
to keep the same SFM.

8mm.
I thought it would be too small, but it has worked very well for years.

One of the problems with the early 'cheap' controllers was the 24V
supply. Simply replacing the driver with one capable of 45 or so volts
made the stepper motor and hardware actually work reliably and I would

Only 3.5Nm ... we are seeing 4Nm NEMA23 now, but I've standardised on
the 3Nm as an alternative to the 1.8Nm and it's only a few pounds more.
They need 4Amp drivers though, so the 3Amp limit of the

Hey Guys,
I have never dealt with stepper motors/drives and one of the guys at our

I've had good luck with the stepper kits for CNC conversion on eBay,
from Wantai or Wantmotor or Longs Motors. These are Asian imports, but
the quality is good. You get the stepper motors, motor drives, DC power
supply to drive the motors and a parallel port card. You can buy kits
with as

A number of the motor manufacturers Galil, Kollmorgen, et al have motor
sizing information information and tools on their web pages that may be
useful. I just had to lookup the Kollmorgen page to make certain that I'd
spelled that correctly so here is a link for them.

That may be due to the step and direction wires being reversed, or one
of the phases being wired

There
Cristian,
When I set up my machine I had the speeds and accelerations set too
high and the motors would just oscillate because they were not able to
overcome the inertia of the leadscrews. Do they behave the same way
when not coupled to the machine? Just a guess. Need more info to

I posted last week about steeper motors maybe week?
So I thought I would follow up and ask some more questions.
Anyway I was using terminal #7 on the gecko 210 tied to my estop to ground to
disable the drive.
This pulls the motor windings to zero, (gecko doc,s)
I always wonder why the drives

Are you sure those are unipolar motors? The geckos are bipolar drives,
and I don't see how they could work with unipolar motors.
Five wire unipolar motors
