Hallo,
I noticed something a few weeks back when I was playing around with magnets and a motor.
When I added a stronger magnet to a certain position in the motor the rpm would suddenly increase! At the same input of power! Added another magnet and it becomes lounder!
A demonstration here!
Now I've researched countless times and found magnetic force on a stator/loop = IL x B
If the magnetic field is strengthen there is more force on the stator and more torque is generated and speed will increase with the same input.
Or even changing the magnet type from ceramic to neodymium(strongest kind) would make a significant change!
Interesting phenomena! Now the thing is... I'm skeptical about is this whole process... What I've learned in physics made me more negative to theses things... And I feel there is something missing/wrong/leading to failure of some sort... One problem was balancing the magnetic field: Easily solvable.
Other problem was friction within the bearings: Can be solved as well...
Also CEMF is considerable but its not really a problem isn't it?
So... What other problems can this due for me? I don't want to get exited and study this and eventually its pointless...
Rpm is not proportional to torque I know that... If one increases the other decreases... But in this case it seems to me like both are evenly increasing... Since were causing a temporary dipole(stator which has current flowing = temporary) to be repelled and attracted by the permanent dipoles' magnetic field... It makes some sense but again I'm skeptical of this effect.
Thanks everyone.
