    Hi,
    I have 2 windscreen motors. As far as I know they are 12v.

    Would putting 24v through blow them, or just shorten there life?

    I'm not sure as I know more voltage would be increased speed and increased speed would be the main problem with damage. But in a motion simulator they are not running at full speed sustained.

    Also I know that higher voltage generally means you need thiner wire, but I don't know how this would effect the motor coil?

    Thanks matt

    I think it will burn the motor coil, i think motor wiper 12v strong use only for the seat not all rig, because i try all rig the wiper very fast hot, its my experience

    You will spoil the engine, if you want more speed you will have to look for another alternative

    You can under volt a DC motor, but over volting will result in damage.

    Doubling the voltage results in four times the power through the motor. I would expect the motor to blow almost immediately. Motors have some safety margin, especially since in an automotive application the voltage often runs 13-14 volts instead of 12v. A windshield wiper motor is likely okay up to about 15v for a short period, but I'm not sure the exact specs.

    You can rewind the motor to handle 24v , but that is a tedious process, you can opt for wiper motors from trucks those are designed to handle 24v, those are also a lot torquier , you can get it for dirt cheap!!!!

    Rewinding the motor I don't think is the best solution, using truck motors is a good idea
