I know I should be running 220V, but that's not an option in my shop. :-(
I have an air cooled spindle out of china. 24,000RPM, 2 Pole, 1.5KW (pic attached). I would like some advice on a VFD that can handle the 110V. I am also using 0-10V to control RPM, so that is a requirement. This is attached to my AvidCNC Desktop Pro 2436 machine.
Thoughts?
Huanyang make one that would run that okQuote:

Nobody really makes them other than the cheap chinese ones.
Better than a Huanyang most VFD Drives are all made in China so what do you call better quality, the quality VFD Drive manufactures don't make such a drive for good reason, most don't have the power requirement's to run a VFD Drive for residential use on 120v power supply, these that are available are made to make a sale there is no such thing as 120v 3phase power in NA you will need around a 25A supply to run your 120v 3 phase1.5Kw spindle motorQuote:

I call better quality in VFD's such as Mitsubishi et-al, these are primarily made and developed in the Nagoya plant, you cannot compare them to Huanyang, who uses a Japanese Micro-controller anyway.
The features, quality and support out-weigh Huanyang by a mile,
When I looked into it, I found out the the Huanyang primarily produce the units in Huan and then are sold through their Chinese sales office, the members of which do not appear to have any sufficient knowledge for technical support, when I made some technical inquiries, they sent me a couple of videos that looked like they had been made in someones basement, the meter they were using were the old moving coil analogue type.No grounding or shielding.
If and when I have ever needed Mits support, the local offices in both Canada and US are staffed by very knowledgeable personell who have a thorough knowledge of the equipment
Also prices are becoming much more competitive.
,
So something like this one? MITSUBISHI FR-D720-042-N7 ?
I understand that VFD is only good for 4.2A@220V (924W), and my motor can handle 8A@110V(880W) (according to the name plate). But the logic in my brain says the wattage is the same. The FR-D720-042-N7 VFD would work and be able to drive my spindle to 100%???? Assuming I feed the VFD a proper 220V. Did I get that right?
I am not sure if Mits supplies a 120v version, your choice may be limited, unfortunately!
Al.
Assuming I feed the VFD a proper 220V
You have to focus on the input current rating of the VFD Drive, this needs to be 1.73 x greater than your spindle amps of a 1.5Kw on 120v is 10A minimum x 1.73=17.3 plus the safety factor / code requirement 125%=21.6 Amps are required to run your spindle on 120v supplyQuote:

Look at the input amps on this VFD is only 6.6a @ 220v a small fraction of what you will need the normal is 1Hp to 2Hp larger than the motor Hp for single phase but it all revolves around the input current rating of the VFD DriveQuote:

Easy way is using a 110Vac to 220VAC up transformer

This would not help at all, as his spindle is rated at 110v, it would help if you under stood what the Thread is about, before posting something that would not workQuote:

if he has a 110V Spindle, he can use 110VAC VFD, This may help

I see you are using my Parameter list on your web page, I can do a more correct Parameter list for you for this VFD Drive, things have changed since I did that Parameter list each VFD Drive model should have it's own listing not all have the same Parameter setQuote:
