Hello, i am trying to hook up power windows in my truck. the motor has two wires and the switch has 3 wires. i just need the relay. i just need to know what kind of relay i need and how to hook it up. i know i need a reversing relay and that it needs to use the 3 switch wires along with the two motor wires and the two power wires. does anyone know what this relay is called and where i could find it online? thank you.
a 3 phase motor has 3 windings whose centers are separated by 120° mechanically. The phases in a 3-phase system are separated by 120° electrically. The sum of the magnetic fields produced by these currents has a constant magnitude, and rotates the direction determined by connection of the phase wires. Arbitrarily giving ABC as one direction of rotation, then BAC = ACB = CBA reverses the rotation of the field in the motor, reversing its rotation.
Hold your horses here as this gets real complicated real fast Motor has two wires one is pos and the other is neg on the down stroke. Reverse applies on the up stroke. Three wires from switch. Center is supply (either ground or 12 v.d.c) Other two are outputs from the supply. (ground is suggested) There are literally 50 different relay types you can use depending on the application. Some are three pin some are four pin and some are five pin. The five pin is the most common type used for power windows. I suggest going to the local junk yard and find a ford F series truck with fuel injection Open hood and look on drivers inner fender well on back side of air filter box. There will be two or three relays under a small plastic cover mounted on slip mounts and if you pull up hard enough they will come off. Cut the wires to these relays as far back towards the dash as you possibly can (to get the most wire possible) You will need two of them per window. These are the commonly sold five pin relays and once you have them then e-mail me through my avatar and I can direct you exactly what wire to what pin to what wire on switch and then to motors.
