Power requirements

[oldoaktree]

I’m moving over to running a palax 100s via an electric motor. I’ll start with just using the pto but come winter I’ll move in doors and power via a generator. 

The instructions say it’s a 15 KV motor but the dealer recommended that I’d need 40 KV as to get the processor up to speed takes a lot of power. Has anyone got any experience on this?

Dumb question but why not get an extra long PTO shaft and stick it through a hole the wall?

That can't be right can it?, a 15 Kw motor will need a good draw to gat it to running speed, but 40 kw? 

 

Any math @openspaceman

He is spot on in what he is saying. Its 3 x the startup power required to run a 15 KVA  3 phase motor which you would most likely need running a processor that big. Have you a 3 phase supply ??

It's Watts x amps = voltage, I think. Someone better at maths than me should be able to give you a clue.

His dealer and myself has told him he needs a 40 kva supply to run a 15 kva motor, No question about it.

Because i have setup the same thing twice and my mate who did it all is an industrial sparky. I have a 3 phase supply in both my workshops and my one 24" 3 phase planer has a 15 KVA motor delta/star  but eggs knows best.

A 3 phase motor starts in star then switches over to Delta, you are pissing up the wrong tree, Les.
