Question:

how can i power a DC motor using the power generated by another motor?

i have an induction motor that produces an AC. i connected it to a full wave rectifier that i made and connected that to a DC motor but it didn't work. and the DC voltage generated by the induction motor alone through the rectifiers is about 60V, but it drops close to 0 once it's connected to the DC motor. is it possible to power 1 motor with the power produced by another motor? is there something, like a capacitor, that i need to connect between the rectifier and the dc motor for this to work?

Answer:

i'm hoping you do not concepts yet i am going to rephrase the question as I see it. If i take advantage of a 4.5 volt direct modern-day motor like an instantaneous modern-day generator, how a lot capacity will it generate ? At a wager with out understanding how briskly you spin the motor/generator and adequate filtering, the load you shop on with to the generator, how briskly you turn the shaft, someplace about 3 to 4 volts at about 100-300mA. you incredibly desire to construct a try rig with the motor appearing as a generator and create a circuit with a 10,000uF 15 volt electrolytic capacitor properly polarised in the course of the output terminals of the motor/generator and then position different resistances in sequence with motor/generator and use a voltmeter to make sure what outputs you are able to anticipate for what rpm you spin the motor/generator at. you would discover out of your finding out a large fluctuation in output and hence some type of regulation circuit will be needed.
Perpetual motion machines don't work.
It will work but nut with what you have. If you get two permanent magnet motors and connect them together and run one with a drill or something it will power the other motor.
I think the problem is the induction motor. Yes, you can generate electricity from it after first applying an external ac supply, then putting in more power than it was taking as a motor. But if you disconnect the load, power generation stops. So use a ac motor with a permanent magnet rotor, rectify that, and you should be good to go.
Power isn't supposed to be generated by motors. Motors are designed to take electric power, and produce mechanical work. Get a generator that is specifically designed to accept mechanical work as an input for electrical power as an output.
