Let’s talk about Magnet Motors.
Working magnet motors do exist. Probably since the industrial age. More commonly known since the 70s with the Howard Johnson motor. They all have the same problems.
• Expensive to build
• Low torque
• Short lived
The only magnets, so far, that have been strong enough to provide ANY significant torque are the rare earth magnets. These are expensive and limited in earthly resources to make.
Magnets have different energies to take advantage of. Polarity attraction/repulsion. Ferromagnetism, the attraction forces of a magnet to iron. The polarity forces will always balance out. However, if your geometry is clever, you can create torque with the ferromagnetism. Ferromagnetism is the weaker of the two forces, so torque created is weak. Thus, for the mass involved in the construction, torque is weak.
All magnet motors to date have consumed their magnetism during operation. This makes them inconsistent for our typical needs of consistent torque to do work. As the magnet motor runs, it’s magnets get weaker, torque lowers, and so does speed. The ferromagnetic material will take on a polarity with time and also stop the functionality of the motor. This can be overcome with geometry, but then you speed up the reduction of magnetism in your driving magnets.
I would love to see a long term, working magnet motor that has no consumables. As in the need to replace the driving magnets. Yes, magnets can be recharged, but then what is the point. If you add electricity and electromagnets to the mix, then you have yourself an electric motor. With the exception of low torque pulse motors, electric motors can function at +90% efficiency. This is not the overunity we seek. I would love to see or build a working, permanent magnetic device that uses no electricity or generates more electricity than it consumes. Which reminds me of the urban legend of the Lockridge motor which no one has seen or been able to replicate
