Alberto, for us to help you it would be best for all concerned if you told us what the application is so that we can suggest the options that are available. In other words what do you want to do with it.

Ok that is why I am asking for help.

I want to use it as a circular for cutting wood.

D.O.L for me mate, that's a wee toy you have there!

Then direct on line (dol) would suffice. Get your electrician to purchase a dol starter complete with overload protection suitable for a 4.4kW motor. You should also consider a braking system and emergency stop button(s).

4.4 kilowatts is an unusual size for a standard induction motor. Are you sure it's not a servo motor you have?

Now there's a thought!

Ouch.............I don't like the way he phrased that !!
"I want to use it"...........future tense.
As opposed to..........."its a circular saw for cutting wood".

Sounds like a 4.4kw motor has been had on the cheap and it's now going to get a great big bloody blade stuck on the end of the shaft come what may !!
Braking and e/stops I doubt lol

I may be wrong of course

i`m in the phone to tony now and tony says DOL...star delta has no advantage on that size of motor...it would cost three times as much....
