Now that is absolutely brilliant.
Thanks for the share
Thanks for the complement bj
This next clip is the rather messy wire winding - the result is OK and it means no joins in the winding but it is time consuming and takes a fair bit of work to get a tidy result.
https://www.youtube.com/watch?v=kYtudDVucUoIt has worked 3 times as that is how many layers I have now!
I was hoping to get a fourth layer on but a trial run with the primary makes me think it won't fit. It weighs in at 31kg now so assuming the mylar and epoxy doesn't amount to much that is at least 5kg of copper on it.
Does the primary need to be all nice and tidy or is it just a matter of getting the wire through the hole? The 3 secondaries are 1.8 mm diameter wire (2.5 sq mm cross section), is that likely to be OK up to 6kw (25amps) or would I be pushing my luck
I have removed the outer (orange) insulation layer from the 50 sq mm welding cable and if I can find some heat shrink then I could go thinner by stripping the white layer but I doubt I would gain a lot for the amount of effort involved.
And just to make my day the LCD on the turbine controller died - random dots flashing all over. I think the 34C outside temperature cooked the battery shed (was over 40C inside) so I've had to hack the code to use an I2C connected display that I had to hand.
Ho hum...
