Below is the circuit schematic of the DC motor now in reverse: Now the motor will spin in the opposite direction with the polarity switch. A Bidirectional DC Motor Circuit Now how can we build a DC motor circuit which is capable of spinning forward and in reverse with the flip of a switch, so that the motor can spin forwards or backwards when we want it to. This has tremendous applications in many different items.

Think of a car that goes forward when in one gear and goes in reverse in another. The motor of the car spins forward for forward drive and then in the reverse direction to go in reverse.

Also think of a power drill which goes forward to drill a nail in the wall and then in reverse to take a nail out of the wall. To build a bidirectional DC motor circuit, we need to use a switch, so that we can go back and forth when we want between forward motion and reverse motion.

This will allow us to make connections to the DC motor so that in one direction, the positive voltage is connected to the positive lead of the DC motor and the ground of voltage is connected to the negative lead of the DC motor, and in the other way, the positive voltage is connected to the negative lead of the DC motor and the ground voltage is connected to the positive lead of the motor.

This will allow forward and reverse voltage with the flip of a switch. Below is the bidirectional DC motor circuit which allows forward and reverse motion with the flip of a switch: When the switch is up, the motor spins in the forward direction. When the switch is thrown down, the motor spins in the opposite direction.

Again, this is how cars, power drills, and many other equipment work. And to vary speed is also a simple concept. To decrease speed, the voltage supplied to the motor needs to be decreased. And to increase speed, the voltage supplied to the motor needs to be increased. So if a motor can operate on V, 3V is when it will operate at its slowest speed. And at 18V is when it will go the fastest it can go. The quantity of voltage varies speed in a motor. Then it will draw more current. Therefore, don't stick your fingers in the fan, as this will slow it down, increase the current, and exceed the current rating.

A transformer will not give you DC. It will give you AC. What you need is called an AC to DC inverter. You can't just feed a DC motor AC.

If you search for power supply, you will find many. It's okay to buy a power supply that can source up to 12 amps at 12VDC.

At half an amp per fan, you could hook up 24 fans in parallel! As is, that's overdesigning. Pick a power supply that can source an amp or two, and that'd be more than enough. Honestly, if there's a power supply in your computer giving 12V, just wire it up to that. Be careful, of course! The DC motor will pull as much current as it needs as long as you supply it the correct voltage 12VDC in this case.

You can wire the fans in parallel like you want as long as your power source can supply enough power to turn as many as you use on. Home Questions Tags Users Unanswered.

Choosing power supply, how to get the voltage and current ratings? Rohan Rohan 3 This is simple and cheap, and also has the advantage of being tested and certified. When choosing a supply, you need: The correct voltage 12VDC , and At least as much current as your fan s will take. So, at least 0. With a light load like 0. This may reduce the lifetime of a continuously running fan. Yes, at least 0. Thus you just need to give the fan 12VDC. Brian Dohler Brian Dohler 3 8.
