A/C supply fan question?
I have a 230V single phase two speed motor that I am trying to check. There are four wires on it. One red, one orange, and two black. The wiring diagram shows the red as Lo and one of the blacks as Hi. The orange is shown as hooking to line voltage and another wire that is not marked on the diagram (I assume the other black). Is there any way to tell with a meter what goes where so that I can bench test it?
yes, the internal wiring of a motor isnt standard, it's whatever the factory wants to use.- at least color-wise. normally they use labels with numbers or numbers with a 'T' before them
you can try the following
hook the orange wire to one power wire and the last one whatever it was to the other power wire - this is the starter circut.
from the point where you hooked up the orange wire hook up either the 'hi' wire or 'lo' wire depending on what speed you want ( you could also wire a 3-way switch to toggle between the hi or lo speed. hook the black or odd colored screw on the switch to the same point where the oraqnge wire connects, the other 2 screws receive the 'hi' and 'lo' wires. this way you can flip the switch between the two speeds)
