Question for John Bedini
Did you actually build and run the PM motor shown in your lab notes, or is this just based on theory?
I tried building one scaled to your drawing and was unable to get it to run. Of course I probably didn't use the correct parts and didn't know what the relative magnet strengths should be. I just use neos that looked in prportion to your drawing and threw it together with aluminum base and rotor. All the fasteners are steel, and the ball bearing is steel.
It cogs to the position shown in my photo. If it is spun, it does coast for a short time (with some drag) and then stops in the same position again.
just curious, thanks
