In this project i combine the two to make a workshop fan that runs of 12v dc.
Convert ac fan to dc.
Converting a 240v ac fan to 12v dc.
Write out the formula v ac 2 and replace v ac with the ac voltage you found with your multimeter.
If by convert a fan you mean turn an existing ac fan into a dc fan.
Converting an ac motor to dc motor is almost impossible and if you were really willing to do so then it would most likely cost more to convert it than to just buy a big dc motor.
Ac motors and dc motors are internally completely different one can t be converted to the other.
It can t be done.
Once you find the watt amount from the ac volts x amps you can divide the watts by dc volts to get dc amps plus 15.

What you need is called an ac to dc inverter.

You can t just feed a dc motor ac.
A transformer will not give you dc.
It s okay to buy a power supply that can source up to 12 amps at 12vdc.
It will give you ac.
If you search for power supply you will find many.
Divide the ac voltage by the square root of 2 to find the dc voltage.
Since an ac power supply sends voltage in alternating waves dc voltage will be lower once you convert it.
Without the efficiency loss ac or dc watts will always be the same because it is total power.
If you need some more help let me know what the application you need a dc motor for and i ll see if i can t help out more.
I have a collection of dead workshop floor fans and a couple of the 24v motors you see in broken kids electric scooters.
