Where can you get a free wiring diagram for a 480 volt reversible motor?

Answer 1

If the motor is 3-phase (it will say so on the nameplate), you don't need a diagram. just hook up all 3 wires in any order. If the motor runs the wrong direction, swap any two of the phases. This is true for all 3-phase motors. Its that simple! Warning: this obviously will only work if you have 480v, 3-phase power available. If you are trying to do this at home, it almost certainly won't work, because homes (in the US) typically have 240v 1-phase power. Trying to run a 3-phase motor directly on single phase power will destroy it. There are various ways to convert single phase power to three phase, but if you are having a hard time just hooking up the motor, they are beyond your ability at this time. Get a qualified electrician to help you! It could save your motor, and quite possibly your life!

Answer 2

dual voltage (high and low volt) 3 phase motors always have the wiring diagram for each voltage printed on the motors nameplate. If it's an old motor and you cannot read the nameplate diagram, go to the manufacturers website and look up the model #.
