Grants Pass TV Repair | Experimental Newman Motor/Generator Part 2 Counter Electromotive Force Demonstration. @GrantsPassTVRepair | Uploaded 4 years ago | Updated 2 hours ago
This is a follow up video to part 1 of my Experimental Motor/Generator. @ https://www.youtube.com/watch?v=MVkSoHrTGMs In my first video I demonstrated an unusual motor I had built, which was based on the idea that a motor could be built to be far more efficient if it contained a larger armature and stator coil than what is found in a conventional motor.
Shortly after I made part 1 of this video, I began removing a large percentage of the wire which was wound around my magnets and tested it again, but much to my surprise my motors speed increased. This was due to having less of an opposing magnetic field from my coil known as Counter Electromotive Force, This force occurs anytime a (rotating magnetic field) cuts across the winding's of a coil. It produces an opposing magnetic field which slows the motor down. In a third video I added 62 pounds of wire to this magnetic armature and the motor went even slower. https://www.youtube.com/watch?v=DKxCPJKRM9Q&t=61s
After seeing this effect I didn't feel to optimistic about winding a larger coil. Based on what I observed it seems predictable that my motors speed will slow down.
I could increase the speed of my motor by increasing the power going into my coil to overcome the losses which occur from the Counter Electromotive Force, but would I really come up with a more efficient motor by doing so? I doubt it.
Conventional thermodynamics says there are limits and I'm wasting my time, but there's a stubborn part of me that still wanted to see it for myself.
Here is a link to part 1 if you have not already seen it. https://www.youtube.com/watch?v=MVkSoHrTGMs
