Mouth structure, upper end annular groove is interior to be equipped with shaft permanent-magnetic clamp 4, and motor permanent-magnetic clamp 8, shaft permanent-magnetic clamp 4, electricity are equipped in the annular groove of lower end
Machine permanent-magnetic clamp 8 is fitted tightly on the outer wall of neckline shaft 1, and the upper end of shaft permanent-magnetic clamp 4 is equipped with axial upper permanent-magnetic clamp 3, lower end
Equipped with axial lower permanent-magnetic clamp 6, side is equipped with radial permanent magnet ring 5, is realized by axial upper permanent-magnetic clamp 3, axial lower permanent-magnetic clamp 6 to turning
The axially position of axis permanent-magnetic clamp 4 and neckline shaft 1 is realized by radial permanent magnet ring 5 to shaft permanent-magnetic clamp 4 and neckline shaft
1 radial positioning, lower end annular groove is interior to be equipped with silicon steel sheet 9 and coil 10, sets between the side and motor permanent-magnetic clamp 8 of silicon steel sheet 9
There is gap, the other side of silicon steel sheet 9 is connected and fixed with fixed bracket 7.
As shown in Figure 1, a kind of permanent magnetism eckband motor, upper end annular groove top portion is connected with motor cover 2, permanent-magnetic clamp in axial direction
3 are fixed at the back side of motor cover 2, and axial lower permanent-magnetic clamp 6 is fixed at the slot bottom of upper end annular groove, radial permanent magnet ring
5 are fixed on the inner wall of fixed bracket 7；Collar structure is that setting is used to store winding in outside in 1 top of neckline shaft
The dovetail groove of line；Shaft permanent-magnetic clamp 4 and axial upper permanent-magnetic clamp 3, axial lower permanent-magnetic clamp 6, radial permanent magnet ring 5 form the connection that suspends,
Motor permanent-magnetic clamp 8 and silicon steel sheet 9, coil 10 form the connection that suspends, and the magnetic field that coil 10 generates provides dynamic to the rotation of neckline shaft 1
Power；Motor cover 2 is mounted on 1 external trapezoidal slot of neckline shaft hereinafter, gap shape between 2 side of motor cover and neckline shaft 1
For an angled straight lines, the other side of motor cover 2 is connected and fixed with fixed bracket 7；Silicon steel sheet 9 with motor permanent-magnetic clamp 8 is coaxial sets
It sets.
As shown in Figure 1, a kind of working principle of permanent magnetism eckband motor is as follows: when motor is worked, to being wrapped in silicon

Motor permanent-magnetic clamp 8 is placed with to position, motor permanent-magnetic clamp 8 drives neckline shaft 1 to be rotated, Jin Erke under magnetic fields
Complete the movement of kinking.The structure that silicon steel sheet 9 and coil 10 form is practical be a small magneto model simplification, the motor sheet
Body revolving speed provides rotary power quickly, to shaft 1.External supporting structure is fixed on lathe, can bear higher revolving speed.Forever
It is connected between magnetic eckband machine shaft 1 and supporting structure using magnetic suspension, friction can be greatly reduced, further increase revolving speed, from
And processing efficiency can be improved.When shaft 1 is generated axial float by external force, the upper permanent-magnetic clamp 3 of axial direction or it is axial descend permanent-magnetic clamp 6 and
The distance between shaft permanent-magnetic clamp 4 reduces, and the repulsive force between permanent-magnetic clamp increases, and can keep balancing with the external force being subject to；Similarly,
When shaft 1 is generated radial-play by external force, the repulsive force that radial permanent magnet ring 5 generates also can keep flat with the external force being subject to
Weighing apparatus.When external force disappears, the repulsion of permanent magnetism interannular can make shaft 1 return to original position.Simultaneously because respectively positioning magnet ring and turning
Distance is smaller between axis permanent-magnetic clamp 4, and mutual repulsion is larger, and after shaft is by external force, diameter, axial displacement are also smaller, because
The operation of this entire motor can be more steady, to be greatly improved machining accuracy.
