Might be a few more days. I will be testing differing timing track layouts over a 90 degree section of the rotor to determine what will work best. That is the purpose of using the Masonite test arcs. After these tests are completed, I will lay out track on the entire 360 degrees of the polycarbonate track base, will spin the rotor up to 100rpm using an external force, and time the rundown to zero rpm. Rundown testing will be done with/without the stator carriage and with/without the flywheel
i built my device with wood and brass-using much smaller neo's to eliminate the large drage forces that you have demonstrated,which will also create drag against the copper coils i use for pickups.
im using reed switches to pulse drive coils-check my latest vid for an update
I saw your videos. Looks like you are into something entirely different with your pulse motor. No input power will be used here - strictly mechanical and magnetic means. By the way, what is a "drage force?" I don't remember demonstrating any of those, whatever they are.
sorry was a typo-drag force of the magnet in the aluminium tube,its attributed to the eddy currents induced in the conductor.
my build was based on the work of Robert Adams and i followed his instructions of eliminating these eddy current losses by not using any steel or aluminium in the construction,and using a brass rod to mount the bearings.
the use of small neo's applies to this engine,yours looks like a different beast altogether.
i share the same dream of PMMG,only mine looks different
Yes, I am aware of the eddy currents. My stator magnet is shielded from the aluminum by its 1/4" thick steel backing plate, and the rotor magnets are located more than 3.5 inches from the aluminum, so I don't fear any problems. I am using a steel bike wheel as the rotor, which works like the permeability plate suggested in Howard Johnson's PMM patent. Good luck to you with your pulse motor, regs.
If you would like to brainstorm, I hope you will join the Pipe Dream Project effort. Further information can be found at the Pipe Dream website. Please see the "info" area at upper right for details.
When is video 22 coming? The whole assembly running, and turning on its own, obviously after a push start.
