Convert ac fan motor to dc.
Enjoy the videos and music you love upload original content and share it all with friends family and the world on youtube.
To convert 110 v ac to 12 v dc you simply need to buy a converter designed for the purpose from an electronics store or online both of which will have many options.
Ac motors in general are very simple reliable efficient and designed to operate at a fixed speed by being supplied with a fixed frequency ac voltage.
The best advice is to check the device you re looking to power to find the input voltage and the input current and buy a converter where the output voltage and current match these values.
A synchronous motor has a source of magnetic field.
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.
Actually it is a table fan of diameter approximately 10 12 inches and runs on ac power at 220v 50hz.
You would need to build or buy an inverter to take the dc and convert it into an ac voltage frequency that was compatible with the motor.
I want to convert it into a windmill but i m stuck on the power generation part.
You can also wire your own converter circuit if you want to try converting ac to dc yourself.
So for a school project i am required to convert an ac motor to a generator.
Then i worked out the best position for the new motor and made a bracket to suit.
How a motor works an electric motor produces a mechanical force when current flows in proximity to a magnetic field.
If you re trying to find out the dc voltage of an ac power supply then use the formula v ac 2 where v ac is the ac voltage.
Foc lets you use dc control techniques for an ac motor and can remove one of the variables in the motor selection process for your next design.
With the 12v dc motor proven to work i removed the old 240vac motor and control box from the floor fan.
