Aliexpress is a sale listing / escrow service for China based companies. Of=
ten I have found items on Aliexpress for the same price as on Ebay, but the=
 item on Aliexpress always seems to be more "complete." I bought a variable=
 frequency drive through Aliexpress for one of my spindle motors a while ba=
ck. It was the only place I could find one that met all my specs.

What is a variable frequency drive?  I know what is sounds like it is but=

Are you just talking about variable 50/60 cycle or something different?
And why would you need that on a spindle drive ( I presume for your CNC mac=
hine)
