SUMMARY

This discussion centers on the feasibility of using two electric motors in a pulley system to recharge a battery, with one motor acting as a generator. The user proposes reversing the polarity of the second motor to function as a generator, but multiple participants clarify that this concept violates the Law of Conservation of Energy, making perpetual motion impossible. They emphasize that energy losses due to inefficiencies in the system will prevent the battery from being recharged effectively, regardless of the pulley ratios used.

PREREQUISITES
  • Understanding of electric motor operation and polarity reversal
  • Basic knowledge of the Law of Conservation of Energy
  • Familiarity with energy conversion processes and efficiency losses
  • Experience with pulley systems and gear ratios
NEXT STEPS
  • Research the principles of energy conversion and efficiency in electric motors
  • Study the Law of Conservation of Energy and its implications for mechanical systems
  • Explore the role of capacitors in energy storage and management
  • Investigate practical applications of gear ratios in mechanical systems
USEFUL FOR

Electronics enthusiasts, hobbyists experimenting with electric motors, and individuals interested in understanding energy systems and conservation principles.

Berry,

What exactly is your theory and what do you hope to achieve by doing this? The contraption seems to be pointless. All you are doing is making a really complicated heater...

You didn't mention the battery in there anywhere, though you said "removing the voltage source"...which you won't be doing if you are charging a battery... The electrons will always go through the motor in the same direction, but in order to charge the battery, you have to drive them through the battery in the opposite direction from which they normally flow.

I'm not sure what you're saying. What I have to go on was a rather crude experiment using fingers to turn the shaft of a small motor. We also have the motor equations, V=KV*rpm, and Torque=KT*I. These equations may continue to hold independent of which way energy is flowing--from the battery to the shaft or conversely. If so, for a motor turning clockwise, if the battery is removed and replaced with a resistor, current will flow in an opposite sense through the windings, and the voltage polarity will remain the same if torque is applied to continue turning the shaft in a clockwise direction.

i hope to achieve an electrical perpetual motion machine, or in better sense to make a electrical self safficient machine to cut out electric companies, that's not illegal because there's people with a crap load of solar panels on the roofs of their houses and their own water source from a home made desail plant using a microwave effect to evaporate the clean water from dirty water and cleaning out the core waste that sits on the bottom of the desail plant.

My theory or idea will be in plan for something much more than cutting out the electric companies. My hope is to change or take out the idea of fossil fuels like crude oil and other kinds of fuels or energy sources to make our home a better and cleaner place to live. there's a thing going on about like when NASA thru up a contest to see who can make a craft that can be easily built that can go in and out of space without a lot of repairs or servicing. guess who did it? the owner of Virgin Mobile.

My little brother is using the same concept as i have been explaining here for another project, just that this idea or theory is the core for my little brothers and my projects. We have big ideas for our home planet to be a cleaner and more enjoyable place to live. Can't have too many people with negetive critism and negetive sarcasm. Just trying to make something impossible into something possible to help our country to be leading in intell once again with a clean source of energy.

well with what i have read from everyones info, i have reversed the negetive and positive from the generators to the battery, so its closed circut

and all that i have read and i put in theory that now my system has lasted 2 days now, as when i first started the system the battery had a full charge, that full charge didnt last but maybe a couple hours, from the minimum charge that the battery had or has now the system is running full speed but its still going without any other power source hooked up

Berry, I suggest a few books before you get your hopes up about your current project. It's great that you strive for alternate power sources, but perhaps more knowledge on the subject would benefit you even more.

An important thing to remember is that even if you manage to create a perpetual motion machine, it could not be used for generating more energy than it was initially given.

Unfortunately you are wasting your time. In the end you will undoubtedly prove to yourself that a PMM cannot exist. The battery will eventually die and require to be recharged from an independent source.

Again, you are just making a really complicated heater.

Ok, well, thanks for being clear. As we've said, what you are trying to do is impossible. Since this is an already exceedingly well-understood area of physics, it is counterproductive and a waste of time to humor your crackpot experiments.

Since you aren't listening to us anyway, there isn't anything to discuss. Thread locked.
