Electrical Question using 2.2kw 220 volt VFD and Spindle in USA

[LiamN (Liam Newcombe)]

Here’s a thread about 110V input 220V output VFDs and step up options;

In a pickle with Spindle & VFD

Hey folks, I’m in a bit of a pickle and hoping to get some feedback. I have a .8kw / 220v spindle and HY01D523B VFD ( single or 3 phase 220v, 1.5Kw ). Now, I actually meant to order a 110v VFD and Huanyang actually makes a 110v input / 220v output 1.5Kw VFD ( HY02D211B-T ) that works with the 220v motor I have. Unfortunately, I can’t find it anywhere . So my questions are: Does anyone else know where to get the 110v In -> 220v out VFD? If I connect single phase 110v to this VFD, what terrible…

It would be unsurprising to run into problems trying to run a 220V spindle on 110V as the winding inductance is designed to require the full drive voltage to hit the full speed, see the voltage / frequency curves in the HuanYang and other manuals.

As for the total power requirement, if you find a non-destructive way to continuously consume the full 3kW input and 2.2kW output of that spindle on a Shapeoko, I will be in the queue to buy you a beer, that will be impressive. I hardly ever use more than a few hundred watts on my spindle which has a 13A fuse and 15A breaker upstream of it on an EU 230V single phase supply.

Your options, other than replacing the spindle are to find a 110V single phase input 220V output VFD as per the other thread or grab a step up converter, as per the other thread again.
