Bedini Style Window Motor

thingiverse

This device represents two models that serve as a foundation for studying radiant or flyback energy. They are designed to be compact and efficient. The main difference between the two designs lies in the ends that hold the bearings, one with three brace tabs and the other with four, which assist with coil placement on both models. Here are three links to videos explaining 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, making it an excellent choice for beginners. This company provides a great kit that can be used with this motor: http://teslagenx.com/kits/tx-sg4tub.html?category=kits|pcb https://www.youtube.com/watch?v=ZYheabS5WBU https://www.youtube.com/watch?v=1r3-KltRWEU https://www.youtube.com/watch?v=EqtP2-h8jm8 There are several options for pulsing these machines. I recommend studying circuits by John Bedini, as there is a wealth of free information available online. Energyscienceforum.com is a great resource where like-minded individuals share and explore this research. Disclaimer: Do not operate these machines if you lack 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: * 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 its non-magnetic properties. You can choose your own wire and batteries. I explain my setup in the videos. A fine-tuned window motor of 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're looking to recover flyback energy, you will need to tune your device using techniques discovered in your research for maximum results. https://www.youtube.com/watch?v=frWQ8Kben5Q This video is an update with the mounting bracket. 08/07/2016 video update with a 50% scale model https://www.youtube.com/watch?v=VkFXT_C94RA Details and parts for this model can be found on this thread: http://www.energyscienceforum.com/showthread.php?t=3380 video update as of 08/07/2016: https://www.youtube.com/watch?v=b95PVtz1xQc video update as of 08/18/2016: https://www.youtube.com/watch?v=EqtP2-h8jm8 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. update 04/08/2017: reed switch holder for large reed switch. http://www.surplus-electronics-sales.com/index.php?main_page=product_info&products_id=299 Print Settings: Printer Brand: Printrbot Rafts: No Supports: Yes Resolution: .2mm Infill: 30% Notes: I printed this with 1.2mm walls and .8mm top and bottom layers. I used PLA filament on an unheated bed. You may need to flip some of the parts over to print, which is easy to do in Cura.
