Will running a homemade wind turbine without a load hurt it?
I’m in the process of building my first wind turbine and was curious if running it without a load (ie. battery bank) would be harmful to the generators? I’m using a 260VDC 5A permanent magnet treadmill motor as the generator. I’m about ready to put up my tower and wasn’t sure if I can go ahead and get it all assembled and put up and then add the battery bank as soon as I can get the batteries. This way I could also see how well it’s going to perform on the tower. It’s a 60′ lattice tower and will be hinged at the bottom but still will be a bit of a pain to lower and raise a lot. I’m really excited about getting this up and running but don’t want to damage anything before I even get started.
Also I’ve heard of people using old electric baseboard heaters as a load dump when the bank gets fully charged. I’m having some trouble locating any of these around here and was wondering if anyone would have any other suggestions on something I could use as a dump? Thanks for all your time.
You will wear the bearings a bit, but there
will be no damage to the generator from
turning without load.
How do you intend to prevent overspeed in
a high wind though?
As to the load bank, if its only 5A., the nichrome
wire units from an old toaster or two would do it.
(Leave em on the mica in free air.)
