Re: [CAD_CAM_EDM_DRO] Brushless servo motors and drives

Hi Vince,
I use those motor for RC Planes and it not to hard to make a control for
them, the bigs problem is the
speed control for the motor, if you go to the bigger motors you will
need upwards of 70-80 amps controller.(100.00)
most of the larger motors are below 750 rpm per volt input, may be
necessary for 2 to 1 drive system for
higher speeds and voltage supply would be in the 24-36 volt range with
40 to 50 amps.
I am working on a spindle for my cnc now and plan on using a big
brushless motor on mine, I have all the
Items because of the RC plane hobby.
Not sure this helps
Bob
