Magnetically Levitated Bedini/Cole Window Pulse Motor by Cotton80
by Thingiverse
Last crawled date: 3 years, 5 months ago
Pulse motors produce little to no heat on the coils when properly wired. That makes pla or abs acceptable materials to make them.
John Bedini and Ron Cole used a solid state circuit along with a configuration of wire (induction coil) along the center of a motor shaft to create what was coined the Bedini/Cole Window motor. This is a highly efficient pulse motor that has an adequate amount of torque to do some usable work. John Bedini rigorously experimented with this technology for over several decades building on the work of others that paved the path before such as Tesla. I believe that he was a genius when it came to electronic circuits. He has held several patents in this work. To do a browser search of the name Bedini brings a wealth of information. He worked with the moderators of this forum: http://www.energyscienceforum.com/forum.php which is a great place to start the journey for learning.
This particular motor/energizer is a fairly simple device that is a tool for learning about radiant energy. Many experiments can be performed with this device.
Disclaimer: This simple device can be very dangerous. Catastrophic failure of parts spinning at high speed can cause damage to property, injury, or even death. There is also a danger of electrical shock. Strong neodymium magnets can cause injury. Build at your own risk.
Parts List:
All magnets were sourced from: http://www.magnet4less.com/
QTY: 32 of .5" X .25" disc magnets for outer magnetic levitation ring
2 ring magnets: 2" outer X 1" inner X .25" depth
6 bar magnets: 2" X .5" X 1/8"
optional for magnetic shaping experiment with rotor: 6 additional 2" X .5" X 1/8"
Those are for the inner slots on the rotor.
4- 12" lengths of 6-32 threaded rod and 8 nuts This is to join the device together.
1/4" smooth rod for the center shaft. I bought a 12" length from VXB Bearings.com
a piece of glass or metal for the pointed end of the shaft or needle to ride against
I use Loctite super glue to secure my parts.
My printed parts are printed on a Printrbot Play with a maximum printing area of 4" X 4" X 5". They are printed in Printrbot Snow White pla. I printed in .2 mm layers, 1.2 mm walls, and .8mm top and bottom layers. Everything was 20% infill except the ring magnet holders. They have 1/8" set screw holes so you should print 50-100% on those two parts.
The wire and pulse circuit is up to you. There is a large variety of options for that.
A circuit such as this: http://www.teslagenx.com/kits/tx-sg4tub.html?category=kits|pcb may be a great place to start.
Please be safe and enjoy!!!! Direct Questions and Comments here: http://www.energyscienceforum.com/showthread.php?t=3380&page=7&p=26245#post26245

The rotor was redesigned so that the magnets are no longer exposed on the outside.
