Does anyone know if a 3 phase lift can be converted to single phase and if so how easy is it to do?

 

Cheers

yes look at machine mart for a similar hp/speed motor in single phase to the one thats on the lift it will probably be quite a bit bigger in size than the 3 phase equivelent. Also you can ask the electricity board to wire you 3 phase into your garage (if thats where your wanting it) but what that costs i dont know.

Cheers Paul. Yeah, I'm looking to put a lift in the back garden (outside and cover it). I'll check it out with the leccie company.

 

Thanks

How many floors have you got in your back garden!!?!?!:D

 

I'd go for OTIS, great lifts and a cool name!:D

 

 

 

 

 

 

(on a serious note, a mate of mine had three phase installed for his new swimming pool. IIRC it cost him £250 from the lekky company for them to bring a line down from the nearest pole.)

you can buy inverters which convert 240 v to three phaze they go to about 2hp motors max i think and the power is slighly choppy but work as i have one on my roller garage shutter door

Richard;) ps you can control the speed and accell&deaccelleration etc

Yes,

We've only got single phase, so I converted ours, our new motor cost about £160 after haggleing for discount, but you need to get one with the right torque output to be similar to the 3 phase you are losing. They use standard sizes on the shafts/fittings, so should just be a straight swap if you order the right one.

 

Or... you could use an invertor to give 3 phase from 1, but this is a very expensive option, I'd go with motor change if I were you.

cheers everyone, that's the info I'm looking for :)

as long as you don't do too many start/stop cycles then I would recommend an inverter- once set up correctly they'll last a lifetime and give the best protection to you're motor and incoming mains supply. a motor just on a standard start stop cycle can draw anything over 6 time it's full load current-- doesn't do much for the bills if it's used alot. the inverter will limit the max current until it's ready to increase the power.a single phase motor WITH IDENTICAL CHARACTERISTICS AS THE 3 PHASE will be large and require a large power supply to drive it. you could look at a motor gearbox combination-- you could get the same speed and torque using a little fractional horse motor and a reduction gearbox.

 

a little long winded, but hope it helps
