"Little Torquey" High Frequency Pulse Energizer

thingiverse

Little Torquey is the same concept as https://www.thingiverse.com/thing:2789344 but it is quite a bit smaller measuring 2.5" in diameter and 2.5" long. Wiring concept should be the same: https://1drv.ms/f/s!Apbifed6cvBmbjLYdzp4fQzMWGA. You should be able to use 28 - 36 AWG magnet wire with this energizer. This will allow you to use smaller batteries if you desire. You can use several methods to pulse this device. I like to use the simple one-transistor Bedini SSG circuit. Parts #6 - 32 X 3/8 in. brass or stainless steel bolts in all locations magnets- 1in. X 1/4 in. X 1/8 in. http://www.magnet4less.com/product_info.php?cPath=1_5&products_id=34 shaft- https://www.servocity.com/0-125-1-8-stainless-steel-precision-shafting 3 to 4 inches should be sufficient. bearings- http://www.vxb.com/SR2ZZ-Ceramic-Si3N4-ABEC-5-1-8-x3-8-x5-32-inch-p/kit8288.htm You can also opt for lower cost crome plated steel bearings with a minimum reduction in performance. magnet wire- your choice. I recommend between 28 - 36 AWG. Printer Settings I printed with pla at .2mm layers 1.2mm wall thickness and .8mm top and bottom layers. Support is not necessary with this design. You can print this model at 200% to double the size. Magnets and bolt sizes will double as well. Disclaimer: Build and experiment at your own risk. Catastrophic failure of parts spinning at high speed can cause damage to property, injury, or even death. There is an electrical function with this experimental device. Do not attempt without experience working with electricity. Do not operate around equipment that is sensitive to electromagnetic frequencies.
