The permanent magnet ring 5 is made of rare earth permanent magnets or ferrite permanent magnets with good magnetic performance, and the suspension winding and the torque winding are both formed by winding electromagnetic coils with good electric conduction and then dipping paint and drying.

The permanent magnet ring 5 provides a first static bias magnetic flux 16 and a second static bias magnetic flux 17, and the magnetic circuit of the first static bias magnetic flux 16 is as follows: the magnetic flux is emitted from the N pole of the permanent magnet ring 5 and passes through the right outer suspension teeth A on the stator core 2 of the right outer motorr1、Br1、Cr1、Dr1、Er1、Fr1The outer air gap 10, the outer rotor core 8, the outer air gap 10, and the left outer motor stator core 1 return to the S pole of the permanent magnet ring 5.

The outer radial levitation control magnetic flux 18 generated by electrifying the outer levitation winding 12 wound on the outer levitation teeth (left outer levitation tooth and right outer levitation tooth) has a magnetic circuit: the suspension teeth on the outer motor stator iron cores (left and right outer motor stator iron cores), the outer air gap 10, the rotor teeth under the outer rotor iron core 8 and the outer motor stator iron cores (left and right outer motor stator iron cores) form a closed loop.
The inner radial suspension control magnetic flux 19 generated by electrifying the inner suspension winding 13 wound on the inner suspension teeth (left inner suspension teeth and right inner suspension teeth) has a magnetic circuit as follows: the suspension teeth on the inner motor stator iron cores (left and right inner motor stator iron cores), the inner air gap 11, the rotor teeth under the inner rotor iron core 9 and the inner motor stator iron cores (left and right inner motor stator iron cores) form a closed loop.
Suspension principle: the static bias magnetic flux I16 and the static bias magnetic flux II 17 interact with the outer radial levitation control magnetic flux 18 and the inner radial levitation control magnetic flux 19 in the radial direction, so that the superposition of air gap magnetic fields on the same side with the radial eccentricity direction of the rotor is weakened, the superposition of air gap magnetic fields in the opposite direction is strengthened, force opposite to the deflection direction of the rotor is generated on the rotor, and the rotor is pulled back to the radial balance position.
