Using a 3 phase lift on a single phase supply

[DKL]

short of installing 3 phase power, which I'm not going to, is this doable or not?
If so how and how much?

Change the motor from three to single - not a good idea if actually possible.

Get a generator - expensive.

[freecar]

You could get an invertor, but again expensive!

Best bet, washing machine motor, some bodgery/general machining ét voila a single phase lift!

[stuttgartmetal]

not without a 1 phase motor change

[schmokin1]

how practicable might it be to change the motor for a domestic 240v supply do we think? Pro's need the lift to whizz up and down, but the average hammer chewer (ie me) wouldn't be bothered if it took longer to lift...

.....or one of them

If it's just the one motor,then converting to single phase is the best option.

[DKL]

How many will it have?
Its all very well getting a cheap lift bu if its going to cost a fortune to get it running I'd rather look at one of the single phase "home use" 4 posters.

[netherfield]

Depends, if it's hydraulic then one,if it's a screw type then up to four.

Some electric motors can be wired to operate on a single phase.
It involves taking off the plate rewiring and either the puttin or taking out of a link.
The pump on my swimming pool has this option.
Whether your motor has this option I obviously don't know.

Don't try it if you are not sure.

Why not just do a search for a single phase motor with the same HP and shaft diameter.

Talk to this guy

What he don't know about phase converters ain't worth knowing

[DKL]

Invertors seem to be rated in hp for some reason and the motors at around 2.5kw. So that would suggest a 3.5 hp invertor.
Most of what I have read suggests an invertor that runs double the output you require so around 7hp.
At that level they are getting expensive - enough to make it not viable to buy an old ramp at a few hundred (plus replacing bits, delivery etc etc) against a purpose built single phase one at a little over 1000.
Or am I missing something?

But get it wrong and you'll wake up in the Jurassic period...

[neilsfishing]

A 1.5 Kw inverter will cost you £200ish Omron are offering a deal for the new ones at £160.00 for 1.5Kw
