I was just planning to convert my manual mill to cnc, i have to do rigid tapping on parts for which a regular induction motors cannot perform. So after an extensive study,i came to know that closed loop Vector based VFD's can perform positional measurement also, as i lack idea on Vector drives i need inputs to move further. The idea of closed loop vector drive was to save cost over Servo motors & drives.
- closed loop spindle for rigid tapping using induction motor instead of servo.
- Emc and cnc drive.com closed loop
- closed loop vector control frequency inverters for energy saving & process control
- can any AC spindle motor be used with closed loop velocity control?
- Looking for a closed loop AC motor/drive combo
