Re: G0704 Spindle Upgrade
That doesn't look like a terrible package. You are going to hurt your torque pretty badly with that overdrive and that will certainly change your feeds and speeds.
Personally I'd go with a BLDC and driver that's capable fo 6k from the factory. 2.2kw is a good range, just make sure it works on 220v, lots of them are 320v especially from Asian vendors.
Re: G0704 Spindle Upgrade
I ended up going a different route and bought a kollmorgen akm42 servo motor. It has about 2hp, 6k rpm, and roughly twice the torque of the other motor. I got a great deal on ebay for a brand new one.
Re: G0704 Spindle Upgrade
Cool! What kind of hardware and software you using to control it?
Re: G0704 Spindle Upgrade
Kollmorgen driver of some sort off of ebay to a normal breakout borad. Using mach3 or 4. havent decided on which one yet. x,y,z axis' will be run with clearpath servo motors.
Re: G0704 Spindle Upgrade
I know this is a old thread but did you ever get the servo installed and were you getting 6000rpm? Also can I get the driver model number?
