QUESTION:
Anyway how much magnetic field CAN couple back via your rotor to the motor itself due to the long steel axle?

ANSWER:
Enough

[Groundloop]

Thane,

I have a hard time trying to understand why the magnetic flux will prefer to go into the motor instead just stay in the soft Iron rotor. As I understand a magnetic flux will always choose to go the way that have the lowest magnetic resistance (reluctance). So If I mount the magnets on the soft Iron rotor,  why will the magnetic flux go into the rotor?

Groundloop.

How do I link my coil flux to the rotor?

TAKE THE MOTOR OUT OF ITS HOUSING.
PUT A STEEL ROTOR ON THE DRIVE SHAFT (WHICH HAS TO BE STEEL NOT ALUMINUM) THEN YOUR MAGNETS ON THE ROTOR AND YOU ARE GOOD TO GO.

Groundloop,
Defering to Thane, another difference I note is that Thane's magnets are housed in steel cylinders, which makes the coil even closer to the rotor.

THE FLUX HAS NO CHOICE SINCE THE ROTOR IS A STATOR INDUCED ELECTROMAGNET
AND EVERYTHING CONNECTED TO IT NOW BECOMES PART OF SAID MAGNET.

LOOK AT THE ROTOR DIAGRAM ON PAGE 12 AND YOU WILL SEE THAT THE ROTOR, DRIVESHAFT AND STEEL ROTOR ALL COMPRISE THE ROTOR ELECTROMAGNET - THE COIL INDUCED BACK EMF MAGNETIC FIELD IS ATTRACTED TO THE ROTOR'S OPPOSITE POLE.

WHAT HAPPENS AT ON END WILL HAPPEN THROUGHOUT BUT THE MMF'S HAVE TO HIGH ENOUGH FOR YOU TO NOTICE ANY CHANGE.

I SHOULD ALSO POINT OUT THAT THE ROTOR (STEEL WHEEL BARREL WHEEL) IS EVERY BIT AS HARD AS THE ROTOR'S DRIVE SHAFT.
