2 phase washing machine

[NotAllThere]

Just replaced the washing machine which came with the house. It was running on 2-phase! ( We have three phase supply, so it had two live connections, a neutral and an earth ).

How does that work then? I understand a three-phase motor from three-phase power, but two-phase motor from three-phase power?

It's all in the combination of the poles...

A transformer will be needed...

Previously, I had a washing machine that had two wires connected to live, one connected to neutral and one to earth.

Now, I've a washing machine with the traditional one-phase approach. I've connect the live to one of the live wires in the junction box, one to neutral, one to earth. And all is ok.

I'm just confused about my old washing machine. With three phase, the three "live" wires are equally out of phase. I can't get my head round how drawing power from two live wires helps. The waveform would not be regular.

Though I've read somewhere that there's a technology that uses one of the lives to drive the motor, and the other to be the brake.

Is it not the case you only get one phase of power delivered to domestic properties?

Your old machine never had three phase, or two phase, just different terminals for the supply.

You lost me after the phrase; "washing machine"........sorry

You stink, by the way. Hurry up and get your clothes washed.

The previous owner left his wife and had her plugged into the mains?

How unusual.
