This avatar looks possibly like the stator and rotor assembly of a ceiling fan motor, one of the more efficient 18 pole type. Looks like Marco has the stator, and rotor locked together with tie wraps. Notice the bolt pattern for the blades at the center of the rotor assembly.

You need lots of poles when the desired rotation speed is low, unless the motor is operated in slip, which is less efficient. This is why the better (more efficient) fans have a large diameter hub.

Well i pulled that out of an old 5'25 floppy disk drive spindle motor.
You know these big floppy's you could bend.
These kind of motors operate with Hall sensors and a 2 or 3 phase controller.
The clock of this one runs at 650Khz.
But i have build better things to test what happens at what speed.

The red coils are bifilar. The red clip represents the inner wind while the white clip is hooked to the outer windings matching up against the white cable ties. The yellow clip is common. The green collector is where the precession happens. Could be iron wire.

In the bifilars we have a field within a field. Pulsed at the right speed the impedance is the delay between the 2 coils.
This still represents a high speed rotating magnetic field. The red statements are the clue. Not looking in a standard way.

Thanks for clarifying that, Marco. I should have noticed it is a little too small for a fan motor, compared to the clipleads. Were you able to get the magnetic field to rotate with this configuration?

No it was just switching coils.
Rotating magnetic fields do not exist.
Magnetic fields are stationary in space.
We can only create the apperance of a rotating field by switching coils or by moving the object that causes this effect.
