As shown in fig. 1, a permanent-magnet collar motor is characterized in that a motor cover 2 is connected and arranged at the top of an upper end ring groove, an axial upper permanent-magnet ring 3 is fixedly arranged on the back surface of the motor cover 2, an axial lower permanent-magnet ring 6 is fixedly arranged at the bottom of the upper end ring groove, and a radial permanent-magnet ring 5 is fixedly arranged on the inner wall of a fixed bracket 7; the neckline structure is a trapezoid groove which is arranged at the inner side and the outer side of the top of the neckline rotating shaft 1 and is used for accommodating the wound wire; the rotating shaft permanent magnet ring 4 is in suspension connection with the axial upper permanent magnet ring 3, the axial lower permanent magnet ring 6 and the radial permanent magnet ring 5, the motor permanent magnet ring 8 is in suspension connection with the silicon steel sheet 9 and the coil 10, and the magnetic field generated by the coil 10 provides power for the rotation of the collar rotating shaft 1; the motor cover 2 is arranged below the trapezoid groove outside the collar rotating shaft 1, a gap between one side of the motor cover 2 and the collar rotating shaft 1 is in an inclined straight line, and the other side of the motor cover 2 is fixedly connected with the fixed bracket 7; the silicon steel sheet 9 and the motor permanent magnet ring 8 are coaxially arranged.
As shown in fig. 1, the working 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 ring 8 is placed at the same axial position of the collar rotating shaft 1, so that the motor permanent magnet ring 8 drives the collar rotating shaft 1 to rotate under the action of the magnetic field, and further the winding action can be completed. The structure formed by the silicon steel sheet 9 and the coil 10 is actually the simplification of a small permanent magnet motor model, and the motor itself rotates rapidly to provide rotary power for the rotating shaft 1. The external supporting structure is fixed on the machine tool and can bear higher rotating speed. The permanent magnet collar motor rotating shaft 1 is in magnetic suspension connection with the supporting structure, so that friction can be greatly reduced, the rotating speed can be further improved, and the processing efficiency can be improved. When the rotating shaft 1 is subjected to external force to generate axial movement, the distance between the axial upper permanent magnetic ring 3 or the axial lower permanent magnetic ring 6 and the rotating shaft permanent magnetic ring 4 is reduced, the repulsive force between the permanent magnetic rings is increased, and the permanent magnetic rings can be balanced with the applied external force; similarly, when the rotating shaft 1 is subjected to external force to generate radial movement, the repulsive force generated by the radial permanent magnet ring 5 can be balanced with the applied external force. When the external force disappears, the repulsive force between the permanent magnet rings can enable the rotating shaft 1 to return to the original position. Meanwhile, as the distance between each positioning magnetic ring and the rotating shaft permanent magnetic ring 4 is smaller, the repulsive force between the positioning magnetic rings and the rotating shaft permanent magnetic ring is larger, and the radial displacement and the axial displacement of the rotating shaft are smaller after the rotating shaft is subjected to external force, the operation of the whole motor can be more stable, and the machining precision can be greatly improved.
