What kind motor is this how does work

[mrel]

Enclosed picture of the motor in pieces.
The big round part is the case for the motor,the second is a small round piece which is a magnet go inside the case.
Than there is blue round piece goes inside the case that has winding of copper wire solid copper wire with a very thin insulating layer,attach at each end is 18 gauge wire.
Maybe with the pictures someone might know what kind of motor it is.
This motor came off antenna made in china.
Picture of antenna is enclosed.
Would like to know how this motor turn with no brushs.

It looks like a shaded pole motor.
The winding produces a magnetic field which is guided and delayed by the metal tabs within the housing to produce a rotating field which attracts the rotor and forces it to turn.
Garden pond pumps work on a similar idea.

It is a permanent magnet synchronous reluctance motor, runs on alternating current, also used in clock movements and seen driving microwave oven turntables.

I have several albeit older clocks that run from the mains, non have permanent magnet rotors.
