I just got my magnets in today. Wow are they strong!!! I walked into the houseboat with them and the tv went haywire...I was over four feet way... I feel sorry...
That would be perfect if you had an annoying apartment neighbor who played his TV too loud - just mount the lot of them on the wall opposite his TV and listen...
It would be fun to mess with some one like that...hahaha But I live in a salt water pond WAY away from other people........and I'm loving it! It gives me...
It sounds like the beginning of a DEW, I once built a 440 tx using some old VT's, i beleive they were 8025's, I inadvertatly wiped out my nieghbors satelite...
Hi, I thought I'd asked this question here before but I cant find it now. Is there a solid correlation between the mumber of magnettic poles on the Rotors and...
I'm kind of new myself, having only studied this for a couple of years, but this is whatt I've learned: Generally speaking more coils mean more power generated...
OK, That makes sense... Many thanks for that. I'm looking at using the device to charge a 12v FLA (Flooded Lead Acid) battery pack. So I don't need a HUGE...
... Most people think of coils as round but they are actually wedge shaped, with the sides being straight and slightly longer than the magnets. There are...
how much gap between the coils and the magnets, how fast are you turning the magnets, did you alternate polarity of the two magnets passing by the coil, are...
In a axial flux, you always have magnets on either side of the coils. I have not ever seen burnout, but then we don't let these things run away. Steve Spence ...
Interesting questions, Steve. The coil to magnet spacing is about 1/16" or so, the magnets are mounted with alternating fields on about a 6" diameter 1/20"...
Steve, funny you should mention burnouts. I was reading a few weeks ago about Hugh Piggot cooking a coil in one of his machines. I thought it funny since he is...
... That may be why some of us are getting higher voltages! Most are using neodymium magnets rather than ceramic. The field density is a lot higher. Field...
Steve, just doing a pencil sketch of 10 magnets and 3 coils, I don't think they really "sync" with all coils passing magnets at same time in rotation. So I'm...
Hi, the coil voltage depends on: PMs remanence, airgap, section of the coil, number of turns in series by coil. So, if you know the values of these parameters,...
Hi, and thanks for that. I was aware of the wedge shaped form of the coils, but the information about number of turns is helpfull. If I'm reading it right...
The resistance of the coil is loss. All other things being equal less turns and higher speed would see less alternator loss. I suspect optimizing gear loss is...
... Be careful since the wire gauge will vary depending on the type of insulation. Some insulations run LOTS hotter safely. David G. LeVine Nashua, NH 03060...
I picked up a set of 24 N50 neo magnets like this on eBay: 110092950419 They are mounted on two 5/16" X 12" steel rotors drilled for 5 bolt Chevy Cavalier...
if you have a runaway wind turbine, it could happen. by having a sufficient wind vane to turn the blades out of the wind, and lowering the tower during ...
I read over at otherpower that they were testing the temp sensors in the magnetos... Was the test good or did they have to do some thing special to the sensor?...
I have been beating my head trying to figure out how I can come up with some disk that are at least 12 inches around. A little bigger wouldn't hurt... I really...
... In theory, thermocouples on twisted pair wiring should not be affected by the changing magnetic field. If they use standard thermocouples with parallel...
That's interesting, this is the wire I was intending to buy. http://www.maplin.co.uk/Search.aspx?criteria=enamelled%20wite&source=15&SD=Y I haven't completely...
