3 Phase Power at Home - VFD, RPC, XYZ?!?!

- In America we don't usually get 3 phase in residential areas so it to run industrial machinery we need to make our own. There's at least a few ways to do this. In this video I talk about my DIY rotary phase converter (RPC) and I install a variable frequency drive (VFD) on my drill press.

Another great explanation. Thank you
Been watching a few things on this and it finally makes sense where that is reactive power and apparent power that finally makes sense.
I think that's the exact same VFD I put on my 3-P bandsaw. I love the way it works. Thanks for sharing!!
Most excellent.
No 3 phase power ? In Denmark every house and appartment has 3 phase power.We have 3 x 400 volt.
Americans like me are very jealous of your electrical grid! Almost all residential areas in the US have 240v single phase.
Is your lathe 220 or 480? Also, couldn't you just wire a vfd to your lathe motor and set it at 60 hz and use it like normal? Most 3 phase 220 is around a 50 to 60 hz frequency.
My lathe can be wired for either voltage. Yeah, vfd could work too.
hi i think is just the video i was looking for, i have a machine that i’m trying to run in my garage at home. it needs 220v 60hz 3 phase power, so all i would need to run it is the VFD and a extra 240v plug right? and wire the 240v into the VFD then VFD to the machine.
thanks a bunch in advance!
Thanks for the question. This topic goes deep. Maybe I’ll make an updated version of this video soon.
VFDs provide frequency/speed control. Some VFDs are designed to take a single phase input and output 3 phase, like the one I’m using for my drill press. I used a VFD for my drill press because I wanted the speed control.
I also have a rotary phase converter (RPC). A very basic DIY version of one is shown in this video, but my new one is from American Rotary and provides more balanced voltage. I now have my lathe and CNC mill running off the RPC. An RPC cannot provide speed control, it only makes 3 phase from single phase, but my lathe has gears for speed control and my CNC mill has its own VFD for the spindle motor and servo motors and controllers for the axis controls.
The point is, the lathe and the CNC mill don’t need additional speed control, so an RPC is the most economical solution for making 3 phase from single phase, particularly for “larger” loads like my 3hp lathe motor and 7hp mill spindle motor.
There are also “digital phase converters” like Phase Perfect, which are designed strictly to make 3 phase from single phase without additional speed control, and they do it more efficiently than RPCs, but for comparison my American Rotary ADX20 costs $2500 and a Phase Perfect 20hp 230v digital converter costs over $9000. There’s a tool on Phase Perfect’s website that helps you calculate energy savings but I’m not running all day every day so an RPC is the best route for me.
You’ll have to weigh the options for your use case. If it’s just one smaller machine like my drill press, a VFD might do the trick for you.
@@RussellMakes I was trying to run a ceramic polisher that has 3 motors attached going into a control box, combine they do 1.9kw. do you think the VFD would be enough?
i don’t believe the polisher has any kind of speed control, just that it needed to run at 60hz. i’m not sure if that makes any sense, i’m not super knowledgeable when it comes to electricity.
@@nicholashsiung3282 the vfd I have wouldn’t be enough. It’s rated to run a 1hp motor. You’ll need to shop around and find something that suits your needs.
Do you command > 60 Hz from the motor when you want to drill at high speed or are you changing the pulley setup? Thanks.
I tried but it would only go up to 70hz. I believe this is to protect the motor as I have the max current set on the vfd to what the motor nameplate says.
