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.
