Washing machine motor with 6 wires
matn1:
Greetings!
I have picked up a mystery motor. Well, not entirely mysterious - the only mystery is how it was wired to the washing machine it was in, as I have found no reference other than that it was made for Haier.
I am attaching 3 images. One is the model number and motor information, which can actually be found online:
http://www.sinomotors.com/rolling.html
Model is YXG162/2/16C6, which is a 110v, 60hz dual speed induction motor.
The puzzling part is the fact that this motor uses 6 wires, none of the wire colors I have found documentation for. Most motors appear to be 5 wire motors, which further confuses me.
I have however taken the time to document the 6 wires resistance (there are a total of 8, with 2 going to a speed encoder).
Wire1: red on connector, black to motor
Wire2: black on connector, grey to motor
Wire3: black on connector, brown to motor
Wire4: brown on connector, red/white to motor
Wire5: brown on connector, blue to motor
Wire6: brown on connector, red to motor
Wires 1 to 3 have continuity and a given resistance.
Wires 4 to 6 have continuity and a given resistance.
None of the sets of 3 wires has any continuity to the others.
1-2: 9.2ohms
1-3: 9.2ohms
2-3: 13.7ohms
4-5: 2.5ohms
4-6: 7.2ohms
5-6: 9.5ohms
Pictures are attached.
I have a cap right sized for this motor and I am ready to start testing it, but I am looking for some basic pointers about what _might_ work so that I stand the least chances to burn it. I really only need it in low speed, not sure I care for high speed, but it would be useful to know both I guess.
Thanks in advance!

Check the resistances carefully again --- especially the first 3. The second 3 look a little closer to what I'd expect from a fixed-direction induction motor with a start and run winding (two of them add together to give the third), like a refrigeration compressor, but I believe these are usually reversible.
Was it known to be in working condition?
radix:
IIRC, these washing machine motors have two sets of windings, a low speed and a high speed one. The low speed winding is symmetrical, as the motor needs to run in both directions. The high speed winding (for the spin cycle) is not symmetrical, as there is no need for reversing the direction during that.
To run the motor, connect one of the supply lines (let's say N) to the center tap of the winding. Connect the capacitor across the outer ends of the winding. The other supply line (that would be L in our case) can then be connected to ONE end of the winding/capacitor. This connection determines direction. If you want the motor to run in the other direction, switch the second supply line (again, L in this example) to the other end of the winding/capacitor.
For the high speed mode the connections are similar, except you can't switch the direction. You MUST connect the incoming supply to the low resistance winding.
Note that it has been quite some time since I last played around with a washing machine motor, so check these instructions somewhere else if you're not sure what you're doing.
I realize that this description might be a bit confusing. I'll try to add a schematic later.
duak:
I used a washing machine motor for a drill press. It was definitly reversible and if I remember correctly, it had two speeds. It did have lots of wires, at least five & probably six. I believe it was from a Hotpoint machine made in the 70's or early 80's. I gave the drill press away so I can't check it out.
Maybe the extra wire was used to supply AC power to some electronics or to a lower voltage solenoid like a lid lock, ie., the motor acted as a transformer.

Have a look and see if this helps.
