Convert Dc Computer Fan To Ac

You can t just feed a dc motor ac.

Convert dc computer fan to ac.

But the magnetic field rotation is generated by electronics electronic commutator. Ac infinity multifan s5 quiet dual 80mm usb fan ul certified for receiver dvr playstation xbox computer cabinet cooling 4 7 out of 5 stars 3 702 14 99 14. The motor is supplied by 12v dc. I needed to adapt a computer fan to a wall plug so i could use it in an egg incubator.

Ac fans are commonly used because the ac outlets are readily available in our houses. At half an amp per fan you could hook up 24 fans in parallel. This means that the dc fan must have an ac to dc converter either externally or included internally in the dc fan to convert ac to dc voltage to power the dc fan. The pros and cons of ac fans.

This simple idea saved me 37 00 over the the cost of the add on unit. Divide the ac voltage by the square root of 2 to find the dc voltage. As the name implies the electronics components convert dc into ac which makes the magnetic field in the stator rotate. What you need is called an ac to dc inverter.

The electronic commutation is achieved by a small ic. If you search for power supply you will find many. A transformer will not give you dc. Write out the formula v ac 2 and replace v ac with the ac voltage you found with your multimeter.

Since an ac power supply sends voltage in alternating waves dc voltage will be lower once you convert it. The dc fans are powered by a constant voltage source. As the name implies the electronics components convert dc into ac which makes the magnetic filed in the stator rotate. It s okay to buy a power supply that can source up to 12 amps at 12vdc.

Energizer 2000 watts power inverter 12v to 110v modified sine wave car inverter dc to ac converter with dual 110 volts ac outlets and 2 usb ports 2 4a ea metlab approved under ul std 458. The electronic commutation is achieved by a small ic. Only 1 left in stock order soon.
