Hey, the video says 400-6000rpm, but the data sheet says 400-3000rpm. Which is it, and are you over speeding the motor x 2? If so, are you guaranteeing the motor for speed damage if it occurs?

Thank you Chris for posting this. Very informative and answered all my questions. I will order one of the 1.1KW motor kit soon for my mill. I've been experimenting with a 1KW treadmill DC motor and although it works well, I have heat issues and and like you mentioned the brushes seem to burn up quickly. But hey I got it cheap so no complaints.

Can you provide the weights for each motor? I might want to make a big bump up to 3hp.

3HP on a G0704? You're kidding, right?

I thought about it. Is that just way too overkill?

In a word, yes. The G0704 structure does not have near enough stiffness to handle that much power. My 2400# knee mill, and my 1600# Novakon Torus Pro couldn't even handle that much power they both top out at about 1.5HP, before the machines stiffness limits what you can do with them.

rs4race,

I build cars for racing and when I plan out a build I always leave plenty of room for growth when buying expensive parts. It baffles me why people don't admit to themselves that they will likely want..... MORE of something when they enjoy it. So I figured buy bigger and open future growth potential Afterall....it is only a motor, whats the difference of the bigger motor over a small one except that it has greater capacity. will it out power the mill....I'm sure it will, But will it out power the next upgrades or larger frame mill? i'll use my method to make sure it doesn't....lol!

No the speed that I am running is within specs of the motor. The documentation needs to be changed from the original spec sheet. The Motor clearly states 400-6000 rpm.
