No motors on the 'machine'?

not without knowing the voltage.

Now you are just being picky....

Now you are just being picky....

why? could be 230V 3 phase, 690V.........

Are you a trainee? If so request access from a mod to the trainee section.

Also we don't just do peoples homework for them, we will guide though if you give it a try first.

@ OP.ever seen this?

P=√3VIxpf

I was joking mate.

To the OP. Have you tried Google. That will give you the formula you need. May even do the calcs for you.

Funnily enough I'm sat in an Amtech design course today, so I'll ask the tutor.

Erm, we dont just give out this sort of info at will.

You are one of 2 things either a trainee in which case apply to join the trainee section and get help. Or charging for this if this is the case then why should we be esrning your money for you?

Your Profile says you are an Apprentice if this is the case do you have a mentor to help you with this.
The Guys are more than willing to help people out but you have to meet them halfway, show us your calculations and the Lads will jump in and assist you.
