is it possible to make a magnetic motor?

Question by sean s: is it possible to make a magnetic motor?
is it possible to make a magnetic motor that will spin on it’s own do to magnetism? if so, can you use a pulley on this motor to drive a generator? and if so, can you use the power of the generator to run a 800 hp electric motor that you would place in the engine compartment of your car if you take the original gas burning engine out?

Yes, all electric motors do that, yes you could use a pulley to run a generator, yes, you could put an 800 hp electric motor in a extremely large car.

The problem is looking at the overall system.
Lets work backward at the parts of the system you propose, an 800 hp motor will dissipate 750 watts per hp, or 800 X 750 your motor would dissipate 600,000 watts. Even at 100% efficiency, that is a lot of power consumed. Your car would need to be about the size of a semi to hold it, or a train engine.
600Kwatts is enough to run 18 homes.

A magnetic motor, would take some input to overcome losses due to resistance in the system. By virtue of touching it or removing energy from the system, even in the process of reading the system you have to remove energy from it you increase loss in the system. Say, you are on a bike heading down hill, and pulling a trailer with the breaks locked, assuming it is not vertical, or greater than 45 degrees, you will have to peddle the bike to make up for the loss the trailer adds to your system. the generator is the same, you take away energy, it must be added.

Long story short, you would need 720,000 watts into the magnetic motor for it to spin driving a generator to run and 800 hp electric motor. This is without taking into account, the losses in the generator.

All this assumes you have an 80% efficient system, which is outstanding for this type of system, in reality, short of some Star Trek answer the system losses would be in the range of about 55 to 72% efficiency for a very well engineered system, which means you will have to lose the belts, to much energy loss, and it would take to many belts.
