Hi....,

I'm trying to do a project SOLAR CAR. But I'm totally confused what motor to be used in that car....?? So please help me in this.

Thank you...!! ,

 

Are you talking about a remote controlled car or about a manned vehicle?

 

You should state the voltage and current capability of your project; there is plenty of choices like the electric bicycles hub motors.

It's very challenging to capture enough solar energy with a vehicle, to move that same vehicle. Everything in between the sunlight and the road must be carefully integrated to get a useful result. High schools and college engineering departments engage in competitions to do this, and their results should help you no matter what scale you are working at.
