[CAD_CAM_EDM_DRO] A Basic Servo Question....WELL ....may be not !!!

Hi All,

Last week I came across a AC Vector Drive Inverter
with which I operate a 5HP AC Induction motor, this
inverter takes +/-10V signal and the Torque I got from
the motor was excellent.
Due to this an idea came into my mind that Why cannot
be this Vector Drive+ Normal AC motor can be used in
CNC machines instead of Servo Motors +Drives? Are
there any other issues which should be considered in
this regard?If it can be done then it would be a very
cheap solution.

To support my idea I would also like to tell you guys
that a few months back I saw a Japanese machining
center (Toshiba's)having Induction motors instead of
AC servo motors for Axes. But I am not sure about the
Drives of these motors becasue no data was available.


Best Regards

Babar
