The DC resistance
between any two pins with any polarity is much higher than I would have
expected: thousands of ohms.
Others have already mentioned:
- It's probably a brushless motor
- Three wires are probably power, ground, and tachometer
The reason you see an unexpectedly high resistance across the power
leads is because there are active electronics inside the thing to
commutate the brushless motor. You're not measuring a motor winding.
I say if you have a red and black wire, hook that up to +5 VDC and see
if she spins.
