A solar motor is a type of motor that uses sunlight to produce mechanical energy. The motor converts the thermal energy from the sun to make the rotor move. The rotor movement produces the needed energy. Solar motors are ideal for industrial applications since they do not necessarily contain moving parts or produce emissions that are harmful to the environment.
However, solar motors can be very costly and have minor drawbacks. In this tutorial, you will learn how to make your own solar motor with very cheap materials like cups and containers. Sizes can be varied, depending on the size of the container. The sunlight will be collected using solar strips. These strips are attached all over the motor to produce the rotor movement.
A small DIY solar motor using cups can spin about 60RPM or one turn per second. Increasing the size of the motor sacrifices the speed, making the rotation slower or about 45RPM. Watch the video to see how the performance of each size is compared.
