GL-45 Motor Upgrade

[KiwiEngineer]

Kia ora everyone,

I recently brought a flogged GL-45 mill which i am currently converting to CNC. It has had about 10 years of work out of an engineering firm, so fair to say the gearbox is tired and quill is a little sloppy. I was going to just replace the bearings and leave it be, but now im thinking i may as well upgrade it.

I want to remove the gears and just belt drive the quill instead. I want to try aim for 3k RPM.

What motors have people run on their RF-45 or RF-45 clones? Any links to where i could buy one would be even better!

Cheers Team!

Hi All,

Ive been busy finishing my control cabinet and everything is working great. I just need to put some settings into my VFD. Can someone please help me with the correct settings. I have a 2.2KW VFD Inverter 220V 10A Three Phase Variable Frequency Drive with a 2 Pole 2.2KW Three Phase Asynchronous motor.

I hope to be running the spindle to 7000rpm with a 2:1 ratio belt drive. The settings i have so far are.
