WASHING MACHINE THREE PHASE ??
(OP)
Please forgive my ignorance, but am I right to presume that any washing machine motor with a bunch of 5 wires attached, like shown below, is a three phase motor? I've seen folk on Youtube control washing machine motors speed with an inverter, so I am just curious to know, is it as simple as seeing the 5 wires attached, to realise it is a three phase motor. (I realise the other two are for the tacho). Thanks

Best bet is to find the service manual for the type you own.

I don't actually have a machine, just this old motor that I want to play around with.
I just got hold of an old inverter but I don't think I will be connecting anything until I get a better idea what's going on.
I noticed on the youtube videos the actual motor stick on badge even said they were three phase.
My one has no mention of three phase.
Thanks

Or another way to put it, if a motor has brushes, (2 brushes), does that mean it can't be a three phase motor?

A three phase motor will have groups of three identical windings, evenly spaced..
A single phase motor will have a set of run windings, often at 90 degree spacing and a second start winding centered midway between the run windings. The start winding is usually a lighter gauge wire than the run winding ans is often recognizable as different than the run winding. A single phase motor will generally have a starting switch and may have capacitors.
There are exceptions to these general comments.

Thanks for all your replies.

Check if your motor has a tacho-generator on the other end, it's just a small round thing sitting on the end of the shaft with a couple of wires coming out.

I like the idea of running from 2Hz to 400Hz so I will search for a 3 phase motor.

I think the spin cycle just switches the number of poles
The motor has about 14 sets of poles, 3 phase for sure. You will see them at high end appliance stores F&P
