Windadct: I really like your response. It agrees with my way of thinking.
Baluncore: Your comments appear to me to apply only to large motors in which the end turns are stacked outside the magnetic influence of the core. On these little motors, the windings are still under the influence of the...
No, the common term is end turns. In many larger motors, the end turns are outside the influence of the magnetic core and have little influence on the total flux.
I have resolved my disagreement with the statement that it is only the slot turns that influence the motor operation. Using the...
"end terns" would be a confusing designator but end turns is commonly used in the business.
I first became involved with this after reading a comment in another thread that stated that only the windings in the stator slots had an effect on the motor and the end turns had no effect.
I think I...
Thanks for your response. The end turns are the portion of the windings that go around the end of the stator tooth. To my surprise, from an analysis of a rectangular loop using Lorentz force analysis there is apparently no contribution to torque from the wires at the end, only the wires in the...
What is the effect of motor winding end turns on torque for small DC brushless motors.?
Many state that end turns have no effect on torque and that the only influence is from the winding portion in the stator slots.
My belief is that because the end turns on small brushless motors are still...
I originally dropped into this thread after stumbling upon it while clearing out some old email.
In January 2005 I had sent an email to Mark Tomion who had a significant presence on the Internet regarding homopolar and Over Unity machines and was the designer of the StarDrive device...
I don't disagree. My point was trying to demonstrate that if the flux return path was asymmetrical there would be a different flux densities through the disk under the return path and under the open part.
That would mean that there would be different voltages generated across the disk when the...
Clever setup, but I see a problem.
If the disk alone is rotated, there will be voltage generated across the disk.
Because of the external return flux path on one side of the disk, the flux density across the disk will not be the same at all points on the disk and there will be significant eddy...
In order for current to flow in a homopolar machine tat least 2 conditions must be met.
1. There must be a closed conducting loop that could be closed not only by a conventional load but by a measuring device such as an oscilloscope.
2. For a voltage to be generated that will cause current to...
I don't know whether this will help, but I found it to be a useful way of looking at a Faraday Homopolar machine when the disk and magnet are moving together.
For reasons unclear to me, there appears to still be discussion as to whether the magnet field rotates with the magnet when the disc...
I stumbled across this thread and would like to offer what I think is a simple explanation to the original poster's question.
"I ask can anyone properly explain why there is induced current in the setup?"If the magnet and the disk are attached and rotate together and I am sitting on the magnet...
