Re: rc car brushless dc motor for x2 mini mill?
There are a couple of big issues here.
That RC car motor is not rated at 1000W for anything like continuous operation. These small motors are simply not able to shed the heat that would entail, and they will get hotter and hotter and quickly expire. The same thing is true of the smaller speed controls. There is a reason 'real' industrial motors with that rating are so much bigger, and more expensive. Without any forced air cooling I would be hesitant to draw more than 200W continuously from that motor. In the RC car world, the term 'continuous' never actually means that - usually it refers to 20 or 30 seconds if you are lucky. Be very careful specifying LiPos as they too suffer from this same rating ethos. A 100C discharge LiPo will absolutely not discharge at that rate from full to flat under any conditions at all.
There are plenty of examples on the forum of people who have successfully used RC brushless motors as spindle drives, but this is normally for high speed auxiliary spindles for small diameter cutting and engraving. If this is what you would require, I would look into a larger, higher kv outrunner style motor and a heavily over-specified ESC. But frankly, you would be better off with a small frame AC motor and VFD. They aren't too expensive in the size you would need and will run continuously all day and all night without any issue at all.
