Losing steps/position, again

[dazp1976]

Ye, I see it as well and now go find me a typical low Nm nema17 or 23 with an inductance of 8Mh.! . . . . .

3nm with 6.8mh https://www.ebay.co.uk/itm/3pcs-Nema...kAAOSw5CZcig1u
3nm with 9mh https://www.ebay.co.uk/itm/1pc-Nema-...1338d93d000784
3nm from supposed respected company: 6.8mh in parallel 27.2mh in series!! wth. https://www.automationtechnologiesin...l23h286-20-8b/
0.54nm Nema17 with 4.8mh is shocking enough afaic. https://www.automationtechnologiesin...epper-motor-3/

See here you go again giving out wrong information and not understanding how steppers work.!!

First, it's 27mh in series not parallel and that isn't uncommon when wired in series. For our needs with routers, it's 6Mh which just means it's a shit motor and to give it a wide birth.

It's a known fact that motors wired in series have higher Mh and require higher voltage if you want speed from them, this is why most of those you list have high inductance. If you look all except the third on list only have 4 wires and are probably Series wound motors.? Again anyone who fits these to a router is a moron who didn't do his research.!

However, all of this doesn't change the fact that your advice that "Doesn't matter wether you have Nema 17/ 23/ 34size motors etc, the drivers regulate output voltage to the motors themselves." is seriously wrong and potentially dangerous if took to the extremes ie: 240Vac drives with nema 17 motors.

I'm done with this now.!!

You asked for examples. I wouldn't use them for paperweights and they theoretically should not be allowed on the market to dupe people.
Would avoid Automation Technologies when it comes to a lot of steppers too. Pretty dire afaic. Seen many recommend A,T. Shocker.

They are not duping people if they provide the relevent details. For some applications they are perfectly fine. It's the users responsabilty to know what they are buying and make sure they are fit for purpose. In case of routers they are not unless used with higher voltages, there are better choices and that's why we use them.

But I do agree I wouldn't use these nasties either even if correct for the job.!!
