proven 2.5 kw ?

[hngni]

hi all

does anyone know the makeup of a proven 2.5kw  turbine @48v

stator number of turns for each coil,

number of coils

size of wire used

how many poles and size of magnets

diameter of magnetic disk

thanks in advance

Ask Proven!

If they are happy to let you copy their design they will give you the details.

Why do you want to know this?. Do you even have any idea of the type of alternator they use, it's not quite the ordinary design.

I do wonder at some of the questions that get asked sometimes.

hi

i know it is a downwind turbine not the usual one with furling system

just curious that they get 2.5 kw from a 3.5m rotor  i have since learned that they use 24 coils 8 coils per phase

do you have any info on this

thanks

I don't have any specific details but if it is like other Proven alternators then it is a torus with coils wound round it without any slots. Magnets face both sides and both sides of the coil are active.

2.5kW from 3.5M seems reasonable for a machine matched to the higher wind speeds. Not sure what wind speed the pitch control starts limiting power but it is likely to be fairly high.

hi flux

thanks for the reply

i am not shure what a torus is or looks like

i know what the normal stator is like

i have built a 48v hugh piggot design wound with 1.6mm wire 90 turns per coil 12 coils, 16 inch mag disks with 16 1x2x1/2 inch n42 neos

it seems good for about around 1kw before the stator starts getting hot when driving it with the lathe

that why i was asking about the proven

thanks again herbie
