  • You can not place something outside the motor that can identify permannet magnet. the mangetic flux flows in the magnetic permisive material (stator) and not in the air.

    This is the answer to the person who asked how to identify Permanent magnets in a motor.

  • This is very easy. Permanent magnet motors have cogging torque. This means that while you rotate the motor shaft with your hand, the position of the rotor tends to be stuck in specific positions within a 360 twist. This happens because the reluctance varies while hopping from one tooth to the next and the magnetic circuit prefers to be found in the least magnetic resistance. This means that if you rotate your PC fan with your hand, it will prefer to be aligned in specific rotor positions.

  • Internal Permanent Magnet Motor is a great one.

    If you want to get the plans for building the Magnetic Generator?

    Just goto Google, search for "Top Magnetic Generator" ...

  • electric motor turning a generator looks like to me.

  • bmw, audi,bentley will go turn the engine with only 2 cylinder for a car hybrid

  • magnets lose their magnetism when they are used too roughly or interact with the same pole a lot of times...right?

  • @MAGNETixFLASHER I have my own plans for such a device. But as you said, it's perplexing that not one of the greatest scientists has created such a machine. I believe it is possible if we can harness the fields of a permanent magnent, using the poles to create almost "perpetual" motion of some kind. This is still a theory however and nothing is written in stone.

  • Excellent video. See my channel electric motor new design.It is very original model of electric motor (it has no accelerating coil, special phase-shifting devices and condensers).

  • Perendev..

  • @egookostis Not all permanent magnet motors have cogging torque. Search for the Muller dynamo and you will see that his overunity design is excellent. Prospathw na to kataskeuasw pantws.
