Convert AC Motor Controller into DC Fan Speed Controller

In this video, we learn how to repurpose a washing machine AC motor speed controller to control the speed of a DC fan. With a few simple diodes and some basic wiring, we turned an old AC controller into a working DC fan speed controller.

This is a great DIY electronics project if you enjoy reusing old parts and exploring practical solutions for motor control. Whether you're into DIY hacks or just want better speed control for your DC fan.

Components Used:

- Washing machine AC motor controller
- Diodes 1N4007 to 10A10
- DC fan
- Basic tools

For the first speed setting, we connected 3 diodes in series
And for the second speed setting, we used 5 diodes in series.

You can adjust the number of diodes depending on how much you want to reduce the speed. The more diodes you add in series, the greater the voltage drop—and therefore, the slower the fan will run.

We used 1-amp diodes (1N4007) for this setup. However, if your load requires more than 1 amp, it's better to use higher-rated diodes like 10A10 (10-amp diodes).

how to convert any motor into high speed dc motor

In this project we learn how to convert any motor into high speed dc motor. its very easy and useful project. High speed dc motors like 775 price is very high and anyone cannot afford. so if we use this simple technique so we can increase speed of any dc motor.

1st open dc motor with the help of screw driver.
Now remove old winding and clean armature of dc motor.
And now take a 22 SWG wire and rewind armature.
Each coil has 10 turn. rewind same like old winding.
And finally adjust this armature on dc motor and close dc motor.

We learn more battery with watching video.

its very simple and useful technique. using this method you can save your money and enjoy with high speed.

how to convert any low rpm dc motor into high rpm 775 dc motor

in this video we learn how to convert low rpm dc motor into high rpm 775 dc motor easy at home. Here we use 3 same company dc motor.

1st motor rewind with 22 swg wire. (10 turn each coil)
2nd motor rewind with 26 swg wire. (20 turn each coil)
And 3rd motor leave it with 32 swg wire. (100 turn each coil)

Now we try run all motors with 4 volt power step by step.

when we run 32 swg winding motor with 4v then its speed is very low.
And when we run 26 swg winding motor with 4v then its speed is little high from 32 swg winding motor.
When we run 22 swg winding motor with 4v then its speed is very high rpm and very powerful.

Mean if we use thick wire for winding then we get low rpm, And if we use fat wire for winding then we get high rpm of any dc motor.

So if we want to increase rpm of any dc motor then we need to rewind it with high swg wire.

we learn it more battery with watching video.

How to convert 24v dc motor into 5v high speed dc motor

In this project we learn how to convert 24v dc motor into 5v high speed dc motor easy at home using few simple steps with the help of video and circuit diagram. for making this project we need some components.

How to convert 24v dc motor into 5v high speed dc motor

Components:

DC Motor 24v or 775motor
24 SWG Wire
Some screw dirvers
Plier (plass)

Normally 24v motor dose not work on 5 volt. because for running this motor we need high power voltage and current. its specially design for high voltage. but we convert it as our desire voltage.

we chose 24 swg because 24 SWG wire start working on 0.6 ampere.

now following few steps and make same.

High speed dc motor winding circuit diagram

1st open dc motor and remove old winding from armature.
This time DC motor wind with 16 swg wire. 16 swg work on 5.46 ampere. so its dose not work on 5v.
Now simple replace old winding with 24 swg wire winding.
Each armatures core 40 turn and after 40 turn connect wire with hook of armatures.
2nd time again 40 turn and connect wire with hook of armatures.
3rd time again 40 last turn and connect again wire with hook of armatures.
And finally last wore connect with 1st wire. like diagram.

we learn it more batter with watching video.

Video of how to convert 24v dc motor into 5v high speed dc motor:

Some basic question and answers:

Whats basic logic with wire gauge with dc motor?

basically each wire has different value of current. if we use low current wire then its work on low current. but if we use high current wire then its work on high current.

for example in 775 motor wind with 16 SWG wire so its dose not work on 5v power (mobile charger) but when we replace this wire with 24 SWG then its working very well.

How do you determine the current rating of a wire?

Normaly we calculate current rating using this formula

Amperage = Current Density * Cross-section Area.

but you can easily find wire current using this current rating chart

How to make 12v kitchen exhaust fan using 775 motor

In this project we learn how to make 12v kitchen exhaust fan using 775 motor easy at home. its very easy, cheapest, and energy saving project. for making this project we need some components.

12v kitchen exhaust fan using 775 motor

Components:

775 DC 12v Motor
12v, 1.8 amp charger
Plastic fan wings
Round rubber (for adjust motor with wing)
2 Iron pieces (for adjust fan with wall)
Some wire

in this project we use 12v DC motor. its very cheap low power and high speed motor. and best for exhaust fan.

Now following some procedure.

adjust round rubber with wing for motor adjustment

adjust rubber with wing

Adjust round rubber in the center of wing. ( because fan wing center hole and motor upper pin size is not same. so we use round rubber for adjust it)

adjust iron pieces with motor

Now adjust 2 iron pieces with motor. one piece adjust wit left side and 2nd adjust with right side. ( this 2 clips use for adjustment fan on kitchen wall)

connect 12v charger power with motor

Now connect wire with motor for input power ( if your charger wire is long then you can directly connect charger wire with motor.)

connect motor with wing

Now adjust plastic fan wing with motor. (motor nozzle pin connect with round rubber its perfectly fit on wing)

adjust 12v exhaust fan on kitchen wall

Finally adjust fan on kitchen wall using screw. (simple hole on wall and iron piece that adjust with motor, and adjust it on wall using screw)

we learn it more batter with watching video.

Video of making 12v kitchen exhaust fan using 775 dc motor:

we can use it with UPS.
we can directly connect it with 12v battery.

because this time electricity is a major problem. so its best alternative of 220v exhaust fan. the total cost of this project is round about 10$. you can also get DC motor form old scrap shop. then this project cost more less. if you cannot find 12v adopter or power supply then you can make it at home using this link.
