Hi Pete my first motor conversion was that new 1/2hp motor which used the offset method for the magnets and I did put that project on this forum. It did run for many years with those 3 metre oregon blades I made that did fail in spectacular fashion with a bit of them still stuck in my shed roof.
Now for decades I was a member of the fieldlines forum where a member called Zubbly came up with this idea that just worked. Oztules did say the motor conversions are bullet proof and won't burn out as the max current will be limited to what the wire can produce then the eddy currents kick so the current will decrease.
The 460 amp figure was just a figure the engineer came up with as he had used them before as I did ask the question about high current brush's.
Now the best site is ontop of the hill which is around 100 metres from my shearing shed so a long cable run will have to be done. Now whats the bet the site I choose is solid rock about 1/2 a metre down so I will have to buy a rock breaker to go on my mini excavator to get to the depth of the hole for the base.
I do intend to make this a downwind turbine and I will be putting a disk brake on so the max speed can be controlled and that 10,000 amp 240 volt switch I have here will be used to short out the turbine. Why use that heavyduty switch well I do have it here and it may aswell get used.
Basically the rule for motor conversions as one is limited to the nameplate so around 4Kw will be the max the turbine can produce. Going over kill on making everything is the way to go so the turbine can last many years.
