Phase Inverter

[Benny]

I g bought a tyre machine and it has a 3 phase motor to turn the table. the motor is 0.75 hp, 0.55 kw. will this inverter work to run it of a normal house supply. http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=180476214756&ssPageName=STRK:MEWAX:IT

Should run about 1HP assuming you can jumper the motor for 230V.

 

[Benny]

Sorry shenion but i havnt a clue what your talking about. Dont know much about AC motors.

you need to be able to re-wire the motor for delta configuration of the windings. On the motor should be a terminal box, if it's got 6 studs and six wires inside, you should be able to do it fine.

if u look at the data plate on motor it will give u the details. it needs to be dual voltage it will say three phase 220/415 volts on it . if its just 415 v it would have to be taken in and wiring inside converted

 

[Benny]

The plate on the machine says 220/415 volts. Do use think i should get the inverter.

as luke says look inside theres links for star or delta they can be swapped to suit the inverter. it should be ok

 

[madkayaker]

should work fine

Just got a message back from the seller and the postage to northern ireland is going to be to much so i think il put in a single phase motor. a friend seen it yesterday and reckons a single phase motor would be about £50.

 

[madkayaker]

an inverter would allow you inferential speed control and forward and backwards and probity DC stop

 

[Benny]

Whats probity dc stop

 

[madkayaker]

bad spelling and a modern safety feature that stops the machine very fast

 

[Benny]

just checked and motor control box has 6 wires and 6 studs

 

[madkayaker]

that's a 3ph induction motor there is probily some metal links and on the back of the lid two drawings a 3 point STAR and a Delta star

 

[Benny]

Yep thats exactly what its like bided on the inverter but didnt get it. Anyone know where to get a cheap inverter?

 

[madkayaker]

eBay?

it went for 26 quid thats quite cheap dont think u will get owt less than that that was cheap

 

[madkayaker]

that's very cheap from RS there £200 +

 

[Benny]

yeah i though it was cheap and i bid on it a couple of times and went to bid again but missed out

 

[Luke]

Crikey you don't want to buy one from RS, whatever it is, it won't be cheap.
