Wind energy, being one of the most important renewable energy sources, and wind turbines, which are necessary for producing wind energy, are very important in today's environmentally aware world. Below we outline detailed information about generators, with many power options right up to 7 MW, as well as one of the most important components of wind turbines and motors that is used in place of generators in individually made wind turbines.
Permanent Magnet DC motors are the most important components that can be used in place of generators. The magnetic fields produced as a result of the spiral movement of the magnet within the component is that which produces electricity.
Why Use a Motor to Generate Electricity?
The most important reason is that it is cheaper than electric generators and it also contains many components we utilize in our daily lives. A motor is a device that converts electric energy into mechanical energy when electrified via its outputs; however, permanent Magnet DC motors can also have some adverse affects. The magnetic field created by the magnets causes a current to flow through a coil. You can see how electricity is produced in the below picture.

 DC Motor Types for Generating Electricityermanent magnet DC motors are divided into two groups. The first is the permanent outer magnet and moving coil, while the second is the permanent coil and moving magnet.
Brushed DC Motor: These motors contain a permanent magnet and a moving coil within the magnet. The required electricity is produced by conveying the energy produced by the revolving brushes. Brushed DC motors are not the preferred method for producing electricity because the coil's, being in continuous motion, can have the following affects on the brushes:
a.) Degradation,
b.) Difficulty in producing electricity because of the brushes
You can see a brushed DC motor in the below;

Brushless DC Motor: These motors are the preferred choice of motors for producing electricity. Thanks to the moving magnet unit in the permanent coil, it easily produces electricity. Producing high efficiency and continuous electricity are the main features of brushless DC motors.
It is one of the most easily found motor types for those that want to build a wind generator at home. Wind energy is converted into rotation energy with the help of the blades installed on the edges of the motor and then converted into electricity with the help of the motor.
You can see images of the brushless DC motor below;

Working Principle of Brushless DC Motor
As mentioned above a magnet with two poles is rotated around a permanent coil to produce electricity.
Detailed information is given in the below picture;

Best Motor Types to Build Wind Energy Turbine
Some types of motors are more efficient than others. With the same wind speed one can produce 10W whereas the other produces 40W.
1.) Treadmill Motors: These motors are both robust and efficient. This is our top recommendation for motors for producing electric energy. You can find them easily online or in stores selling second hand products. They cost between $20 and $250. Because of its values in relation to output current and output voltage, it can easily be used as wind turbine generator.
2.) Stepper Motors: Although highly efficient, stepper motors have a lower output voltage and current than treadmill motors. It can be used in wind systems that have a lower power output.
3.) Standard Permanent Magnet Motor: These are for people who want produce electricity out of wind energy. They are cheaper than treadmill motors but some have higher HP levels. Sold for $20 - $1500, standard permanent magnet motors are our second choice for wind energy systems.
