hi atom,
So that I clear this for my own interest, I dismantled an old hard drive and removed the 4 wire motor.
Resistance values as per your findings, approx 2
hm:
Determined which wire was which in the firing order.
Used a dual beam scope, kept one channel as reference and spun the motor by hand,
observed the other windings on the second scope channel in order to find the phasing.
Applied 5V in the firing sequence, the motor turns in 30deg 'steps', BUT there is very little torque.
Attempting to drive anything from the motor shaft would be pointless
This is exactly what papabravo has been saying thru this post.
However, looking at the output from the windings in would make an interesting project for a wind speed indicator.
[ I expect thats been done already!]
Hope this helps.
