Wiper Motor for ROBOWARS

[Himeel Shah]

I m thinking to use 12V wiper motor for robowars...becoz it has got vry high torque.
But cant find its rpm.
can any1 tell approx. rpm of a standard wiper motor of a midsize car??

I can't tell you RPM but I can tell you its too slow. Use a pair of drill gearboxes much more in the ballpark of RPM you need.

Is this for Techfest Comp?

The normal windshield wiper motor has a worm gear that is about 50 to 1. So it multiplies the motor's torque about 50 times, and also slows the motor down about 50 times.

So the final rotations per minute is about 60 at 12 Volts, and about half that at 5 Volts. Good torque, but slow speed.

Yup Steve its a techfest comp..
