Some problem of Spindle and VFD

[geiyubeibei]

Hi

I'm making on progress on planning my first machine and am now looking for some recommendations to hopefully avoid buying the wrong components.

Spindle and VFD

I'm considering these:
VFD 3.7KW 5HP 17A 220V Variable Frequency Drive Motor Inverter

and
Air Cooled 220V 2.2KW 8A 24000RPM 400Hz ER20 Collet
https://www.oyostepper.it/category-76-b ... o-CNC.html

This will be my first time with a VFD and "proper" Spindle - how does a 2.2KW spindle compare to a Dewalt 1/4 router (as this is the only reference I have)?

The machine will be used on average 2 hours each day so I'm looking for a set-up that won't give up after a few months, but at the same time, I'm looking to keep costs reasonably low.


Sensors

I plan on using M12 Inductive sensors, NPN, NC, but it seems these can range from £5 - £150. I've been looking on ebay or amazon: https://www.amazon.co.uk/mxuteuk-Ind...&rps=1&sr=8-12

I'm hoping to avoid buying cheap items that are unrelaible.

Thanks
