--Previous Message-- If you have time can you take a peek at the guy who posted his notes and schematics on his water powered 1978 V8 Camaro. It's at http://www.waterpoweredcar.com/1978camero.html and let me know what you think of his circuit. His piggy backing of a half wave rectified signal on top of the distributor output through relay contacts appears to be drawn incorrectly. Thanks very much for your time. Jerry
: : Again thank you Bert.
: You mentioned that a mulitlayer coil would be better suited and easier to
: wind than flat pancaked ones. I'm not quite following what the difference
: would be. The coil that I had planned to use was of course 300 turns of
: 23awg with a 2" aircore and then pancake 10-15 other layers on top
: with each connected in series.
: Tesla's patent referred to a single layer spiral with NO stacking of
: layers (since this would actually defeat the purpose of the patent). If
: you wound a series of single layers and connected them in series, this
: would create a multilayer coil.
: How is the mulitlayer coil you're talking
: about built? Lastly as I'm using about a maximum of 300vdc into the coils
: would it be better to use more turns of a narrower gauge wire or stick
: with the gauge I have?
: I'd recommend simply winding flat layers, one on top of the other, using
: tape to separate layers if necessary. Using an applied voltage of 300 VDC,
: you may also need to have some form of external current limiting (beyond
: using just wire resistance). You'll also need to look at the amount of
: physical space you have available for the windings. Because of the
: relatively low wire resistance of #23 AWG wire, you may need a way to
: externally limit the current that will flow through the coil, or limit the
: ON time versus OFF time (duty cycle) so that the winding doesn't overheat.
: Looking at 23 AWG: Close-winding 23 AWG magnet wire will only give you
: about 41 turns/inch, so no matter how you wind it, a 4500 turn coil will
: occupy considerable space and weight (probably at least 7-8 pounds of
: magnet wire). 23 AWG has ~20.3 ohms/1000 feet, and about 648 feet/pound,
: so you'll need to bend the numbers for your proposed coils. I'd suggest
: using a significantly smaller wire diameter (perhaps #28 or so) so that
: you can get higher winding density, particularly if used with a high duty
: cycle. Assuming 8 pounds of wire (almost one 1 mile of wire), the
: resistance would be about 105 ohms. For 300 volts, the steady state
: current would be 2.85 amps, and the power dissipated in the coil (as heat)
: would be about 855 watts. With no external current limiting, the coil will
: get VERY hot, VERY quickly, and will burn up.
:Sorry I took so long getting back to you, work is occupying way too much of my time. =)
I see your point on the smaller wire diameter makes perfect sense. My original intention was to use the heavier gauge to get a stronger field. But from what I'm understanding is that I can achieve the same magnetic field by using more windings of a smaller gauge. Is that correct?
I will have shortly two motors on test stands, one Honda 4 cylinder and 1 12A rotary motor for testing of several ideas we've read about. This one intrigues us the most. We would greatly appreciate your opinion on this.
