Electric Motors/Single phase dual voltage wiring.
I have been given a single phase motor, dual voltage 2hp, but no wiring diagram. It has 6 terminals numbered 1, 2, 3, 4, 5, and 6. 1&3 have a jumper, 2&4 have a jumper. It does have a capacitor. 1 through 4 have black wires going into the motor. 5 and 6 have red.
Most likely 1-3 is line 2-4 is line red wires are some sort of thermal protector with an ohm meter we could tell exactly
1-2-3-4 should be the motor leads, slight chance the red wires are the start circuit, if so one each would go to 1-3 and 2-4 which are parallel or low voltage connected
so it should be 115/230 and 115 would go to 1-3, then 2-4 if the reds are a winding which I doubt one each to lines
or the red wires could be the cap wires, hard to say with no data,
but it is odd normally no one uses red for a winding but for a thermal would be somewhat normal,
you say capacitor but not if it is wired or just with the motor, and what kind of cap, is it in a metal can or a plastic canister?
If it is plastic and has a rating like 365 it is a start cap, if it is metal probably silver it is a run cap and would have a rating like 5, 7.5, or something down in that value
Can you send photos of the wires coming out, or get an ohm meter?
The high voltage connection would be line to 1, and line to 4 with 2-3 electrically connected and taped up as a series jumper,
But that would mean the reds [if start winding] would have to be connected to one line and the 2-3 jumper to keep it at 115 volts or low volts
Whatever the rating is low or high not important exactly what should be 115\230 110/220 so on one twice the other,
Motors are not all common duty motors like you buy off the shelf somewhere,
many are made for a specific device and they do all kinds of things, but to color up windings would be very OEM
If you can get an ohm meter I need you to take a photo so you can get it back as it was,
and if you get an ohm meter I will tell you what to measure then we can narrow down the windings by ohms, and get much closer,
For now I would wire nut reds each, put 110 on 1-3 and 2-4 see if you get rotation or it might take off,
but if there is a cap but you dont say if it is connected or not,
if the cap is wired then try the wire nuts on reds
line wired as directed above to 1-3 and then 2-4 it should hum if the red is the start,
might take off with a shove but be damn careful if it does and has a keyway it will eat your finger so try but best to wrap a string and pull it, if possible in both directions
or give it a spin prior to wiring the last power line connect one hard with a nut, expose the other and touch the other line to it, it might spark no problem but be careful that way too no good way to do this so be careful either way or not at all if you are concerned
then put the reds on the lines and if takes off it is the start circuit, but without an ohm meter it is the best guessing I can do,
if it takes off with the reds on line reversing the reds from line to line should change rotation, but I doubt it is a winding if it is thermal the ohm reading could be really low almost nothing or like a short, but hard to tell how they connected in the motor itself,
measuring the windings 1-3 are now connected so the circuits should be 1 to 2 and 3 to 4
sometimes they use 1 to 3 and 2 to 4 that is just the WIRE and each set is half the winding and should measure in ohms almost exactly if not it is shorted also put the lead on the 1234 and one lead to the case where you find bare metal or scrap it with a file
if the windings leads 1234 show a circuit to the frame the motor is grounded do not use it can be grounded and not "shorted" or it could be shorted and not grounded or both either way anything from winding to frame stop !!!!!!!!!!!!!!
send me photos or ohm readings or tell me you have a meter and we go from there
let me know
