Thanks Hesham, its good , but thats are for little motors such as Cd-Rom Motor Driver ,[hobby Helicopters]

i want drive a 1HP Motor for example. because its for a CNC machine ,

Did you actually look at these specs? Some of these will easily handle a kilowatt or more. Much more than 1HP.

hi jobezo ,
Are you sure here is a Up to 1kw BLDC or Ac Servo Driver ? i search , but i dont find this :( i need this immadiate but i cant find :((

Hesham , thanks for links but i dont find any circuite , here are good informations about Servo and servo driving but im not a Electronic engineer :( im waiting for your companionship, thanks

and so sorry for my baaaaaaaaad inglish , :p

hello
here is a 1 phase/3phase controller design.
i have not tested it yet and have not completed the software.
i will complete it this year

Would there need to be much modification to make these designs work for AC servos?

Probably alot depends on whether you want to close the loop in the drive, If so you probably need to go with a Dsp based design, for open loop drive where the loop is closed via motor feedback to the controller then some thing like the Motorola MC33033P would work.
