So torque is the biggest weakness of my tiny PCB motor. This was measured it to be 0.9gcm.

But it is something that can be improved. These are three ways how I tried to improve it:

Why not stack the PCBs? e.g. PCB, rotor, PCB, rotor, etc... 

On the stacked rotors, doesn't the magnetic field from one side interfere with the field on the other side? e.g. you have to separate the stacks and provide each rotor with it's own PCB windings. Perhaps as much as 10 or 20 mm.
