As shown in fig. 1, the operating principle of a permanent magnet collar motor is as follows: when the motor works, the coil 10 wound on the silicon steel sheet 9 is electrified, the silicon steel sheet 9 generates a magnetic field under the action of the electrified coil 10, and the motor permanent magnet rings 8 are arranged at the same axial position of the collar rotating shaft 1, so that the collar rotating shaft 1 is driven to rotate by the motor permanent magnet rings 8 under the action of the magnetic field, and the action of wire winding can be further completed.

The external support structure is fixed to the machine tool and can withstand high rotational speeds. The rotating shaft 1 of the permanent magnet collar motor is connected with the supporting structure in a magnetic suspension mode, so that friction can be greatly reduced, the rotating speed is further improved, and the machining efficiency can be improved. When the rotating shaft 1 generates axial movement under the action of external force, the distance between the axial upper permanent magnet ring 3 or the axial lower permanent magnet ring 6 and the rotating shaft permanent magnet ring 4 is reduced, the repulsive force between the permanent magnet rings is increased, and the balance can be kept with the external force; similarly, when the rotating shaft 1 moves radially under an external force, the repulsive force generated by the radial permanent magnet ring 5 can also keep balance with the external force. When the external force disappears, the repulsion force between the permanent magnet rings can make the rotating shaft 1 return to the original position. Meanwhile, the distance between each positioning magnetic ring and the rotating shaft permanent magnetic ring 4 is small, the mutual repulsion force is large, and the radial and axial displacement is small after the rotating shaft is subjected to external force, so that the whole motor can run more stably, and the processing precision can be greatly improved.
