[stewart1980]

hi there i am starting my own company and i have just bought a new tyre machine my unit has single phase but the machine is 3 phase with 4 wires black blue brown yellow and green on the side of motor it has v-220/380 now can i use this in my unit and if so how do i go by doing it please help as losing money now with it not working

You'll probably end up either replacing the motor with a single phase equivalent or upgrading the electrical supply in your unit to 3-phase.

 

[stewart1980]

what is the cheaper option

 

[Marvo]

Can you attach a snap shot of the motor? If not what is the kilowatt rating and rpm? Maybe a make and model number.

this is all it says on motor v220/380 ph3 hz50 hp1 kw0.75 a 3,8 - 2,2

Or possibly you might be able to use a Single > 3Phase converter box, but that'll depend a bit on the device and how chunky the motor is for the cost... As others have said, a single phase motor may be an easier conversion.

 

[telectrix]

a single phase motor should cost you around £100ish, max. then you'll need somebody to get the right one and fit it. probably another £100ish.

There's an identical thread here, it's going to get confusing.

i'd think a second hand inverter would be cheaper

 

[stewart1980]

would this do it IMO Jaguar VXS Single to 3 Phase Inverter 0.75KW

Single phase to 3 phase inverter 0.75KW


Removed from working control panel


Comes mounted on heatsink with built in line filter​

If you go the inverter route I would suggest oversizing it to acommodate the start current and the fact it's an AC3 load with less than idea power factor.

I’ve given my views in the other thread. I’m not repeating them.
