Answer pole and the second induction pole, the second magnetic die group 12 by the second partition groove 121 formed mutually independent third induction pole and
4th induction pole just will not be magnetized at this time in this way, to form groove since middle part has been hollowed out and generate magnetic force, therefore
Rotor 2 just only will receive the magnetic force at 12 both ends of the first magnetic die group 11 and the second magnetic die group, without by from middle part
Magnetic force.Accordingly, between the first pole the S magnet 21 and the first pole N magnet 22 of rotor, the 2nd pole N magnet 23 and the 2nd pole S magnet
Groove corresponding with the first partition groove 111 and the second partition groove 121 is also equipped between 24.The effect of groove on rotor
It is to prevent the component between two magnet to be magnetized and influence so that magnetic force direction becomes so that keep apart between two magnet
It obtains indefinite.
When a certain the first magnetic die of moment group 11 is the pole N, at this point, the first induction pole generates suction to the first pole S magnet 21
Gravitation, and the second induction pole generates repulsive force to the first pole N magnet 22, the first magnetic die group 11 driving rotor 2 rotates counterclockwise.
During this, due to offering the first partition groove 111 between the first induction pole and the second induction pole, just it will not generate herein
Upset the magnetic force of rotor stress.By being provided with the first partition groove 111 and the second partition groove 121, magnetic can not only be provided
Power realizes the reciprocally swinging of rotor 2, also makes magnetic force direction caused by the first magnetic die group 11 and the second magnetic die group 12 more
Add and define, the reset function of conventional reset spring can be realized without reset spring is arranged.Due to without reset spring,
Therefore vibrating motor can be realized swing by a larger margin, improve cleaning effect, moreover it is possible to completely eliminate noise, improve user's body
