Pulse motors typically do not get hot when wired correctly. They are not to be confused with DC Brushless motors which use advanced circuits to pulse energy through the coils. This pulse motor represents a tool to experiment with. I use the Bedini SSG circuit to pulse this energizer. You can go here: http://www.energyscienceforum.com/forumdisplay.php?f=48 to learn about that technology. It is a simple circuit that most people can learn to put together in a short period of time. This company offers a Bedini SSG Circuit kit that will work with this energizer: http://teslagenx.com/kits/tx-sg4tub.html?category=kits|pcb. You can use other methods to pulse if you desire.
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.
parts list:
the magnetic wire is your choice
transistor(s): the slots are made to fit the mjl21194g transistor
It uses a double stack of the popular sized ceramic magnets (1-7/8" X 7/8" X 3/8") like these :https://www.harborfreight.com/pack-of-2-ceramic-block-magnets-97504.html
all bolts are 6-32. For the inner motor you can use 3/8" length at every point.
for the motor housing you can use 1" to 1.125" at every point
It is important to note here that nonmagnetic hardware (brass, stainless steel, nylon) allows for the best performance.
shaft: 1/2" X at least 6" stainless steel or aluminum
magnet rotor set screw: 6-32 X 5/8" (note: you will need to grind a flat spot on the shaft or drill a hole in it for the set screw)
bearings: It is recommended to use at least ABEC-5 like these: http://www.vxb.com/SR8-2RS-Ceramic-ABEC-5-1-2-x1-1-8-x5-16-inch-p/kit13852.htm I bought and used cheaper bearings for the demonstration model like these: http://www.vxb.com/R8-2RS-Sealed-Bearing-1-2-x1-1-8-x5-16-inch-p/kit7478.htm
I used pla for this motor. It was designed to print .01" larger at each location for the bolts, magnets, and bearings to compensate for shrinkage. print settings where .2mm for layer height, 1.2mm walls, .8mm top and bottom layers and 20% - 30% for the infill.
Three printable part files were added to be able to use 8mm rods and skateboard bearings. These bearings are tried and true: https://bonesbearings.com/bones-reg-swiss-skateboard-bearings-8-pack It is recomended to use at least ABEC-5 bearings and a non-magnetic shaft for optimal performance.
2/24/2018 I added a magnet cover for additional support. This should add some safety when spinning at higher rpm's. A better option would be a fiberglass or carbon fiber layer. This should also be accompanied with 100% infill on the rotor for high speed experiments. Also don't forget to glue your magnets in place. I like Gorilla Glue. It seems to handle shock and vibration the best. Make sure you use water or it won't set properly.
2/25/2018 I added some small panels to help keep the "Window" wire off of the rotor. I recommend using Loctite (5 sec) Super Glue. Just dab a little on each end and attach them to the center.
2/26/2018 added 1/16" shaft spacers which may be needed to provide a snug fit for the rotor between the bearings
3/01/2018 added some slightly more robust parts for those that want to run it up to higher rpm's. The trade off here is stronger parts but more plastic + longer print times. I still recommend printing at higher infills (greater than 30%) and glueing your magnets in place. It is also still recommended to create at least 1.2mm walls. These parts are listed as #1, #2, and #3. They are still interchangeable with the other listed parts. Sorry, these are for 8mm rods and bearings only.
01/16/2019 I added a simple low profile motor mount. You can use this to mount to a project board. It is a minimalistic design so that you can print fast and use for light duty experiments.
02/07/2019 One of the biggest issues that I have had with this design is keeping the wires from rubbing against the rotor. The wire_protector design is somewhat flimsy. So, I designed a new wire/rotor protector that is more rigid. It will also help better organize and concentrate the magnetic flux and should offer better performance according to the wiring diagram that I have provided. They are made to glue to each side of the motor ribs but I have found that with my prints they actually just snap in place! Pictured in Hatchbox Gold PLA filament.
