Im looking for a little advice about using an RC brushless motor for a spindle.
My current plan is to machine a housing from aluminum and press a couple of angular contact bearings into each end.
Iv ordered a C10 ER11 100 collet shank, and hopefully I will be able to cut an external thread on the end for a lock nut.
Then I can either go direct drive from the motor, or use a pully.
Will use an arduino to control the speed controller, and probably a separate power supply just for the spindle.
Can anyone recommend suitable spindle speeds for cutting aluminium?
Or better recommend a motor and power supply.
Iv had a quick look on ebay and most of the motors draw a huge amount of current. What power supplies are people using to power these things with?
The biggest 12v led power supply iv found is 600w.
