Is it possible to balance the blade rotor by wrapping the tips of the blades with lead tape (for tennis racquets)? I was curious if the rotor balancing has to...
I'd do a lot more than just wrapping things on the blade tip, that would be askinf for "unidentified flying objects" when the rotor got up to speed....
Balance at the blade roots, not the tips! They'll never hold together at the tips. At our shop, we use lead tire weights or decoy weights screwed on near the...
You know the real physics behind this balance is really kind of neat I think. Essentially, balancing the rotors can be done in any location you choose, it...
Good thoughts, Steve. On our model airplane props (2 blades0 we usually scrape or sand the heavy blade to balance, on a one blader, the counterweight has to...

You actually end up with more in the favored direction. It is the strongest achievable field with PM. Kirk ... Okay,I'm a little dense on some things, but why...
my understanding is that current is generated when copper wire coils are forced to move thru magnetic flux we all know how rotors are forced .. by use of water...
Obviously if the magnets are same size the array will weigh several times more. If the array is the same size as a single magnet you need to talk to...
Hmm, not sure what that was all about but let me pose a question. So let's say we are building a axial flux generator using a Halbach array. Just for...
I think you can fill the resin with aluminum oxide and improve the thermal characterisics. Kirk drstb2 <drstb2@...> wrote: Hmm, not sure what that was...
my only point is this : halbach arrays have augmented magnetic field on one side and cancelled (almost) magnetic field lines on the other side this would give...
... strength. ... many makers are working with halbach arrays .. and the much higher magnetic field strenght on one side of such arrays is a well known,...
Peekay, It's not going to make all that much difference. What it will do for you is allow you do build the rotors from something other than the heavy brake...
It's an interesting program and good for doing "what if" type stuff. They have a newer version that what I have out now that does even more stuff. I like...
since my question was to find out if anyone has tinkered around with halbach arrays in this group ( " i was just curious whether anyone here has tinkered...
Hey Peekay, Don't let my experience's from last year stop you if your really looking to try building one... check for magnets again, some company may be making...
I have long considered a reciprocating alternator for wind generation....... and had the idea ridiculed at times. My idea of course is to construct a wind...
hi howard, therear e plenty of linear alternator designs if you look for them on the uspto site. i have thought of this in the past but decided there wasnt...
I have an off the wall sort of question for all you guys that have built many of these things. I attached a picture of something I'm thinking about trying for...
The real question is how to get the maximum flux change through the coil and keep the cogging to a tolerable level. How about a slotted aluminum stator disk...
Reciprocating machines start and stop all the time. Difficult to accomodate. Remember power from magnets and a turn of wire has 2 variables Magnetic field...

At the risk of going way off-topic.; I'm building various rotors for my F*** energy group. One of the guys asked if I'd be up to building a"device" that...
