controlling motor with the right current

[sevi29]

here's a circuit that i've made to control 2 wiper motors:


this circuit worked but the wiper motor is not rotating the way i want it. i mean it rotates too slow.

i tried using the l293d which is a motor driver to control the direction of motor and it worked for dc motor, but when i tried the wiper motor, the same result happened but when i tried connecting it to a transformer with 12 v, 3 amps power supply, it did rotate fast. so i'm guessing that maybe, the wiper motor needs a high current.

here's the regulated power supply that i've used:


so i've put another component, the relays, because it gives high current for the motors, but only needs less current to be triggered.

it does work, but then again, the wiper motor does not rotate the way it should be.

Why not look at the datasheet for the 7812 voltage regulator and see that its maximum current is only about 1A?
Why not look at the datasheet and see that its maximum allowed continuous output is only 1A?

You have the relays connected completely wrong and they are missing important diodes.
