Where to buy from cheap servo motors/drives ? For a small machine, around 200W and one 400W to move the gantry using 2 ball screws.
Any chance in Europe? China?

define cheap :D
a bit more expensive than stepper :hysterical:Quote:

Brushed or brushless?
Brushless start at around $450 US. Very little price difference between 200 and 400w.
It does not matter really.
I found leadshine have some new motor which i did not know of
Integrated servo motors NEMA 23 motor with1000 encoder & a servo drive at one machine can output 2NM Torque
Quite a contenders for what i need them.
wow for that price they look pretty good eh
im using the DMM kit , for the first time in 6 months the machine skipped , but im sure its a mach3/pc issue
get a set and let us know how they work :D is this for a new project ?
Yes. I have a new project in mind. Bluntly said- I want to make and sell the best small machines in the market.
I would like also to be the most affordable for what it offers, so all parts which are not produced by me must be industrial quality but at good price to keep overall price down. I have several strategies to achieve this and one of them is everything to be as easy/ fast/ to assemble as possible.
I have the sketchup design finished. Now i am redrawing it in NX, cause i would like a perfect CAD model. Some time ago i started a thread which i will soon update. There would be also some secrecy, until i am not ready with the prototype. I have 3 standard small machines in mind to sell, all share Z design, rails spacing and so. Already tested design on the yellow machine, my first build, which again i have to note is capable of milling aluminum with perfect finish while Z is fully extended at 200mm and digging 1.5-2mm in the aluminum.
So i decided to start with the 6040machine, moving gantry. There will be 6090 and 4040 fixed gantry.
hence the servo search.
They are stepper motors not servo (Integrated version of the Easy servo system)
Sorry, you are right of course. I messed up with so many browser open windows. I meant that oneQuote:

So they are really just a closed loop stepper system.Quote:
A Leadshine integrated easy servo motor consists of a high torque stepper motor, a rotary encoder, and an integrated DSP-based digital easy servo drive.
