Bedini Style Window Motor by Cotton80
by Thingiverse
Last crawled date: 3 years ago
This Thing represents two models which are a basis for studying radiant or flyback energy. They are a compact design. The difference between the two designs is in the ends that hold the bearings. You will see that one has three brace tabs and the other has four. This assist with the coil placement on both models. Here are three links to videos to explain each.
The original designs and applications for these motors should be credited to John Bedini and Ron Cole. The Bedini SSG Circuit can be used to pulse this motor. It is a good one to start out with. This company provides a great kit that can be used with this motor: http://teslagenx.com/kits/tx-sg4tub.html?category=kits|pcb

There are several options for pulsing these machines. I would recommend that you study circuits by John Bedini. A search through the internet yields loads of free information. Also, Energyscienceforum.com is a place where this research is explored and shared by like-minded individuals. Disclaimer: Do not operate these machines if you do not have experience with electrical, electronics, and mechanical systems. Catastrophic failure of parts at high rpm can cause injury, death, or destruction of property. Operate at your own risk.
Parts List: Qty:
Magnets- 2" X 1/2" X 1/4" N 42 Neodymium Magnets 6
Sourced from www.magnet4less.com nsnsns arrangement
Bearings- 1/4" X 3/4" X 7/32" R4A Open Ball Bearings 2
Sourced from VXB Bearings (can be upgraded for better performance)
Shaft- 6" X 1/4" linear motion hardened steel 1
Sourced from VXB Bearings (can be upgraded to non-magnetic material)
Brass bolts and nuts Sourced from Lowe's 6 or 8 depending on model
1/4" - 20 X 1 round slotted brass bolts 1/4" - 20 Brass Hex Nuts
Brass is essential due to non-magnetic properties
It's your choice on the wire and batteries. I explain what I use in the videos. A fine tuned window motor this size can run in the micro amp range. I have run mine between .75 amps (2800 rpm's with the two flywheels) down to between 15 - 20 milliamps (470 rpm's). If you are looking to recover flyback energy you will need to tune your device with techniques discovered in your research for maximum results.

update 08/19/2016: A 3 to 1 rubber band pulley system was added as well as a .25" square magnet trigger wheel for reed or hall switching. The trigger magnet disc can be used in place of the small pulley. Be extra careful when drilling these out with .25" drill bit;) for the shaft.
update 08/28/2016: A 7 to 3 to 1 rubber band pulley system was added as well as a .25" square magnet trigger shaft for capacitor discharge.
update 09/06/2016: The rotor was updated to include bearing standoffs on both sides. You must use support on the bottom.
