Cool video showing how ampere goes up as load increases.

Lower Left = volt
Lower Right = ampere
Top = No idea ...RPM can't be that low, or probably it is in a submultiple form

I'm trying to find out some info on DC motors, what I'm trying to find out is DC volt output when you spin it with an AC motor with a belt and pulley....I want to try to produce a constant 24 or 48 voltage to power a whole house inverter....PM me if you don't want to clog up this thread, thx....

You will convert the dc voltage in to AC 115 volt. You need to first calculate the max power (kW) consumption of your house. Then the next step will be selecting the right inverter. And then the dc generator and ac motor that spins the generator.

Another thing to note is that how are you going to supply power to the AC motor that spins the generator? Will it be 115volt single phase or will it be a 3 phase AC motor. If you use a single phase AC motor, the current (ampere) requirement is going to go quite high. Reason is there will be energy conversion losses and to meet the normal power requirement of the house the AC motor input of power will be almost 1.75 times higher than what you might get at the end.

if you don't want to clog up this thread, thx....

:lmao: Don't worry at all my dear friend"thumbsup"

The AC motor spins the DC generator to power the inverter to run the AC motor that spins the DC generator. Sounds like a solid plan to me. :ror:

The AC motor spins the DC generator to power the inverter to run the AC motor that spins the DC generator. Sounds like a solid plan to me. :ror:

Overunity was not mentioned in the plan:ror:

The AC motor spins the DC generator to power the inverter to run the AC motor that spins the DC generator. Sounds like a solid plan to me. :ror:

If you can get at least 2 of the motors to run at around 125% efficiency it should work fine.

I'm trying to come up with a way to eliminate some items from a solar panel powered battery bank that uses chargers and everything else needed to power a 24 or 48 volt whole house inverter....working with different sized pulleys to get the best RPM to spin a DC motor to get a constant 24 or 48 volts that a solar set up gives....I'm sure a DC motor and even a couple in stock and on hand in case a switch out is needed, will be cheaper then a solar/battery set up that will need new batteries every 6/7 years....my MacGyver mind set always has shit rattling around inside my head "thumbsup" ....

This is how magnets are made.

Various metal powers > Mixing in right proportion > Melting in vacuum furnace to form ingots > Powdering of ingots > Die pressing the powder > Sintering > Machining or grinding > Nickel coating > Magnetization> Finished product.

This video shows ferrite magnets being magnetized which takes a second to do so. This same process is used for NdFeB magnets.
