Specific embodiment
Be described further below technical scheme, but claimed scope be not limited to it is described.
As shown in Fig. 2 a kind of axial same polarity bonding magnetic steel method, the method is to introduce one block of magnet steel III 3 to be used to aid in
Processing, the Distribution of Magnetic Field of two blocks of same polarity magnet steel I 1 and magnet steel II 2 is changed by introducing the magnetic field of magnet steel III 3, to weaken magnet steel I
Repulsive force between 1 and magnet steel II 2, so as to realize the bonding of same polarity magnet steel, enables two blocks of same polarity magnet steel to be fitted tightly over
On axle 4.
The axial same polarity bonding magnetic steel method and step is as follows：
(1) installation axle upper magnetic steel：A face coated with adhesive bonding with axle 4 on magnet steel I 1 and magnet steel II 2, and by magnet steel
I 1 and magnet steel II 2 on adjacent be bonded in the surface of axle 4；
(2) magnet steel III 3 is placed on the surface of magnet steel I 1 and magnet steel II 2；To eliminate the repulsion between magnet steel I 1, magnet steel II 2
Power, improves bonding magnetic steel quality and bonding efficiency；
