Thank you very much. Very useful.
The driver you mentioned is hard to get and very expensive.
I tried to find a cheaper BLDC controler.
But found none.
Am i overlooking something ?
Hi..
I want to connect a BLDC bodine 34B6FEBL to a VFD YL620-A

The motor is 130 volt.

This sherline mill with less then 100 watt spindle seems to be doing fine.
Without vastly more power then 250 watt.
I would be very happy with these results:...
Yes..
Sort of maybe...
Other part of the question is, why is 500 watt or 1500 watt needed for hobbyist.
A 100 watt will also be very useful.
Is there a cheap version for sale of the sherline spindle headstock on this link ?
And if not, why not ?????????...
Hi..
Can not find the answer..
After homing, how can i see how much the automatic touch off to zero has corrected the home pos ?
Thanks...

Hi Folks.
Did you know you can use the spectroid app on a android smartphone as a tachometer.
If you put a little piece of tape as a flag on the spindle, the sound is measured and the frequency...
Hi..
There are several high speed spindles which work up to 24000 RPM.
On the other hand i have seen mills with max 2400 RPM, only a tenth of the speed.
But what would be a reasonable range,...
Hi...
I read about 6000 RPM as lowest speed for air cooled spindles.
But what is roughly the lowest for water cooled spindles ?
Thanks..
Hi Folks.

hi Uli,
I can not find the link to this pdf on UHU Servo.
Where is the link ?
Vroemm.
The UHU partslist at http://gsst.wikispaces.com/UHUget has the order codes of the german site reichelt.de
If you ordered from the netherlands you had to buy at least for 150 euro.
Now reichelt...

It has been 3 years ago.

Hi All.
Why is there a lot less activity in the UHU forum ?
Same on the german peters cnc ecke forum.
Has an other servo controller become more popular then the UHU ?
Vroemm.
I did not give you information.
I asked a question.
Can a disc rotor motor be used with the UHU ?
Has anyone done it successfully ?
Can disc servo motors be controlled with the standard UHU servo controller ?
Has anyone done this ?
I thought disc servo motor where somehow different in ampere usage.
Some thing like a much...

No need to apologize.
It is wonderful, after 3 years you gave us a useful answer :-)
I have bookmarked, saved to hd, and printed the info you gave :-)
Thanks !

I had not thought about this before.
Thanks for the safety tip.
