Project Description

•      Wind charger is operating using 12V battery. This system is using LCD to show wind generator and battery voltage. When the battery voltage is low, motor will charge the battery.

•      When system is operating, voltage sensor detect wind generator voltage and show on LCD. Voltage sensor detects battery voltage. If battery voltage more than 12V, green LED will turn on. Else, red LED will turn on. Battery voltage will show on LCD.

Condition : Battery is charging.

Yellow LED indicates system runs, red battery is not full and green for charging the battery.

Condition : Battery is not charging.

Yellow LED indicates system runs, green LED for  battery is full.

Coupling DC motors

   · Voltage produced by a single motor with wind turbine is not sufficient enough to charge up 12V DC battery.

     ·  In this case coupling DC motors are introduced. There are six numbers of couplings that are being connected in series connection to get higher voltage. Need a motor with battery supply of 6V to drive another motor. In this case it became DC generator. The motor that is used to drive is a replacement of wind source.

     ·  By using this method, the motor that is driven will produce higher voltage which is approximately 1.5V each coupling compared to a single motor with wind turbine which only produce only 0.14V.

  · The reason why every coupling has its own battery supply of 6V instead of using one supply to all six couplings is because voltage drop does not occur. Using one supply to all six couplings will produce voltage drop and in this case some of the motors do not have sufficient voltage to drive another motor.

How to make wind turbine blades

The easiest object that you can find to make wind turbine blades is by using drink can. The main reason why drink can is being chose at the first place is about the material which is light in weight. Because of this the wind turbine can spins smoother and easier. Besides that, the material is flexible. Flexible in this case means to shape something. The wind turbine needs to be airfoil in shape. Because of this airfoil shape, it will be easier for the wind turbine to spin when there is wind energy source. A can of drink normally would cost you only RM1.50 and you it can be found anywhere. It is good to use recycle items to make something useful out of it.  Below shows the steps in order to make wind turbine blades:-
