I have a Whirlpool dryer motor (model number S58NXMKE-6674 or part number: 3395652.) Image below:
This is a type of universal motor that uses an electromagnet instead of a permanent magnet in the stator region.
I have a hypothesis that I may be wiring this device improperly. I've also observed a curious thing. When using an ohmmeter to measure the resistance between the two red wires (which I assume are for the brushes giver their larger diameter) I get an overload condition, indicating non-continuity.
I have a picture of what the wiring situation looks like below:
Using the multimeter's connectivity mode I've determined that the black wire is not connected to anything, and that the bright green wire on the bottom is the case's ground connection.
This just leaves the two large red wires (which I believe were directly wired to the 120 V; one was wired to the mode selector switch I think), and the two smaller wires (the sky blue one, and the white one) which I believe are the field coils.
What is the proper wiring for this? I've assumed that the two red wires are for the brushes and tried a wiring scheme of (all are series connections): Hot wire -> red wire 0, red wire 1 -> field winding 0, field winding 1 -> neutral.
When I flipped the switch, nothing happened and my clamp on multimeter read 0 A when clamped just on the hot wire. Granted I was using 120 V, but I would have expected a burst of 12 A or so and for the motor to start spinning; this didn't happen.
Is the black wire relevant somehow, or is it just used for a computer to manage speed or RPM or stats or something like that? What is the correct wiring for this type of motor?
Edit 0: Judging from the comments this is almost certainly an induction motor without a capacitor. I'll retry it with a new setup tomorrow.
