Hey guys, I need some input. I have wanted to build a minature 5 axis for a long time and would like to begin sourcing parts. I would like to have a spindle controlled via the controller, probably Mach4 with the G-Rex. I have no idea what kind of motor touse for the spindle but following are some of the wishes.
1. Controllable for speed
2. At least 6000 rpm for max but more would not be turned down
3. Small as in very small! Torque isn't an issue as only small parts will be cut.
What do I look for?
Would either of these work?
1) 10,000 RPM Miniature 36mm ULTRASPINDLE NEW Brushless Motor
Diameter = 24.6mm, Height = 36mm,
Rugged, shock resistant,
Three Phase, 0.6 ohms/phase motor. High torque from rare earth magnets,
Highest quality ball bearings, Designed for 300,000 hour MTBF.
APPLICATIONS: Diamond Turning, Optical scanners, Gyroscopes, Stabilizers $49/ea

2) 10,000 RPM Miniature 20mm ULTRASPINDLE NEW Brushless Motor
Diameter = 24.6mm, Height = 20mm,
Rugged, shock resistant,
Three Phase, 0.6 ohms/phase motor. High torque from rare earth magnets,
Highest quality ball bearings, Designed for 300,000 hour MTBF.
APPLICATIONS: Diamond Turning, Optical scanners, Gyroscopes, Stabilizers $39/ea
If so, what would I need to drive the motor and control it?
