Forgive me for I have some questions in my writing, aswell as some options.
That's a lot of terminals coming out from that box,
Some of those wires are thinner gauge than others,
I wonder what Bob (myfordman) would make of it?
Could it actually be a dual voltage afterall?
If you can't find him here, then look on the "would haven two" website said in code as software dosen't like competition.
His google document is worth reading concerning motors and VFD's.
Guineafowl21's knowledgeable comments are worth going over,
and to try and delve in a bit further, some other questions could be answered
to make your options a bit more simple.
Are these extra terminals for a motor brake I wonder, and can that be disabled?
I would have thought safety interlock switches were on the switch/isolator side of things.
(safety interlock swithes are so you can't open doors while machine running, or could be for a foot brake also)
Can you trace the micro switches to the on/off isolator switch?
I seem to recall that some of those Jet bandsaws has the option for cutting metal,
I thought that would not be anything to do with the electrical side of things, and is a manual change of the belt onto a different pulley.
It is a four pole motor running at 1440 RPM, so that would suggest it can be used for both metal and wood.
Has a 4 pole motor less starting inertia, i.e easier on the supply to start?
It says its a 2.2kw on that motor sticker, or 3hp motor, which is stated either on my machine or the rated VFD/inverter @ 11 amps rating, presumably for startup or full depth cutting only, and not 5 amps what's written on the motor sticker.
Presuming there is no other diagrams of anything on the inside of the lid you took off?
As said above, a motor swap to single phase is one option,
Have you got a 16a socket in the shed, or any plan to run a dust extractor with machinery together in the workshop?
Then ideally you might want to just swap it for a single phase motor which has the same 3 hp/ 2.2Kw rating, which is a 4 pole motor running at half
If so make sure you get the same shaft size, research if it's foot mounted, face mounted or flange mounted motor also as that pulley could be double the width and need the right motor mounting,
i.e the motor might need to be tight against the machine cabinet to account for this.
If you have only 13 amp sockets, with a suitable beefy line going to the house, and it is not an option to get an electrican to hook up 16a outlets, then I would think
2 hp might be as powerful a motor you can install on a 13a household plug.
I could be wrong though, and am interested if that 4 pole motor will be less consumptive on startup.
i.e wont blow fuses on the household plug.
The other option of a cheapo step up to 400v drive might be interesting in this regard also...
It would be interesting to know if that voltage step up might be a challenge for the cheapie VFD's all the time, or if it may be more likely to fail with a 2 pole motor during startup.
Another thing that would be interesting to know is if the star point could be more of an easier job than some motors, but that requires some knowledge to do, and ideally a megger which aint cheap.
Sorry I can't be of more help, but it might make way for more knowledgable folks than a numpty like myself, and hopefully yield a pleasing outcome by getting the ball rolling.
