Hi All,

Does anyone know if a Warco VMC 3 phase motor can be run in delta i.e 220v?

I enquired at the Doncaster show and the guy I spoke to on the stand had no clue except to tell me that they are waiting for some new VMC's that included speed control, but were a couple of months away.

I'd rather use an inverter than a converter, but despite searching various forums and the interweb, I can find nothing relevant

Thanks for any help

The motor should have a plate on it which should say whether its dual voltage or not.

Most modern motors usually are.

Anyway, at worst a new motor can be bought from ebay for under £100.

I would go for it..

Does anyone have a 3 phase VMC that would take a photo of the rating plate? …

Alternatively, there should be a box on the motor where the cable connects to the windings with a cover plate. If you take this off and take a photo of the connections it should be possible to see if both ends of each winding are brought out, in which case it can be connected in delta. It may even be connected in delta already.

If in the motor terminal box there are SIX terminals, then yes it can be easily connected in 240 Delta a five minute job. If it has only three terminals and two wires to each of the three making a total of six then again it can be connected in Delta. But if it has only three terminals and three wires the motor has to taken apart and internally reconnected, So that you have six wires available.A member of this site published a series of photos and some text on how he did a conversion about 6 months ago. I'm sure Neil will point out the location for you. On most motors its not difficult at all, its worth taking the motor apart to locate the star point, which is where THREE wires are joined together. Your local rewind shop will do it for you, should take them an hour,for a fee of course, worth asking before buying another motor.John

Thanks for the help guys, it's not how to do it that is the problem, it's IF it can be done. Warco don't seem to know and I thought someone might have the 3 phase version VMC on the forum.
