Laguna bandsaws come from ACM an Italian brand.
I suggest you look at three phase machines for that money with a £100 thereabouts VFD to run it, if your in a home workshop.
Especially if you only have a 13a socket to plug into, as its 2HP max which a single phase motor on a 13a plug will handle...
and if it does you might be popping fuses all the time.
This is because the starting current of these motors will go far and beyond the rating of the plug fuse.
But you can run a 3HP 3 phase motor on a VFD from a 13a plug all day long no bother atall.
I have a 24" ACM and run it from a really weak supply in a dodgy wired house with no bother, whilst a 1HP single phase pillar drill
will dim the lights!, as will even a wee household vacuum cleaner.
Really easy to hook up a VFD with no electrical knowledge beyond wiring a household plug.
If your looking for a saw similar to the the Laguna's for example, or any newish machine, say from the last 30 years
it will have a three phase
dual voltage motor.
To check this, look on the
motor nameplate, not elsewhere on the machine.
You will see 220/240v on the nameplate, which means it can run on household power with a VFD
If you see this go grab yourself a bargain, as three phase machines are half the price of single phase machinery.
All you will have to do is open the plastic motor terminals cover and make sure the 6 terminals are orientated to Delta (triangle symbol)
which is low voltage mode, takes about 30 seconds to do.
You will have 4 wires coming from motor to the VFD output with
no plug inbetween
These wires will be 3 "hots" and an earth wire.
These 3 hots, go into the output terminals of the VFD, doesn't matter which orientation by the way, it might run backwards, and if so
just switch any of the two hots for correct rotation of band wheels...
Just make sure your blade is off when testing or the blade could walk off the tires.
The most important rule of safety is to wait for the VFD to discharge power before going near power terminals!
So coming from your household wall plug you have your live, neutral and earth
Live and neutral go into input terminals and both the earth from the plug and the earth from the motor get joined together and insert into the earth terminal.
That's it for wiring these up basically to make it run from the VFD panel.
Before that though, you need to buy the VFD first and make a sheet metal dust shroud for the VFD/inverter, tomato/tomato
If you choose an inverter drive with small power terminals you may want to bolt the earths to the metal shroud/box with another short earth stacked ontop to fit into the small earth terminal.
I suggest the Isacon/askpower VFD's as there's auto shutoff technology for the cooling (wee computer) fan, as it can be annoying
with it running all the time.
So a rundown of costs and stuff so far...
Bout 700 quid for a 200kg 20" wheeled machine
Around 100 quid or less for an Isacon VFD
Box for VFD make yourself, this can mount where the original switches went on the bandsaw.
From the electrical shop you will need...
Cable glands if you want to do it nicely, as these will be dustproof and have strain relief ...
one for the motor input, this is a 4 core wire, and a 3 core wire cable gland for the household supply.
Say 4 quid... which go into VFD box.
Crimp connectors to fit the gauge wire, to fit into VFD terminals
say 2 quid for a bundle...
If you have a good pound shop nearby you can buy a cheap crimping tool for £2 or do it with a pliers that has a smooth area/no teeth.
the crimp connectors should squish the wire into a flat shape.
Next you will need a short amount of really thin wire because you want to hook up a switch,
1 core from some thin wire from an old electrical appliance for example.
The Isacon/askpower needs a relay if you want to go all out with the switches and have stops everywhere...
I now have a simple toggle switch on the bandsaw so don't need a relay this way.
Switches cost no more than £3 on the bay each
It is probably frowned upon as I also have 2 mushroom stops with this toggle switch...
If you hit the twist lock mushroom stop, it might be good practice to have an arrow to tell you the toggle switch location
as if you untwist the stop button, and the toggle is still flicked to the on button the machine will start again.
You might want to just use a toggle and forget about the Twist lock off buttons
Or get a start button and the twist lock stop, and buy a relay for a fiver.
(I haven't been on eBay in a long time to get one)
Whatever VFD you buy, most have the slightly annoying fan running all the time
but have a built in £5 relay allready,
Make sure you enter the correct motor parameters or you could burn out your motor easily, running on factory high speed
default values, which would make your motor burn out, trying to turn eight times faster than it should!
In europe we run on 50hz
The manuals on these are sometimes hard to figure out, so I recommend you get one that has documentation from someone on a
forum like from here, as all brands differ in the programming.
Enter the correct values in the right sequence, before hitting the run button!
