Poly- magnetic portion 83 is right against between S poles magnet and N poles magnet, and N poles group of magnets 31 and S poles group of magnets 32 remain static.When to
When coil 7 accesses positive and negative square wave power, coil 7 is powered and generates magnetic field, and magnetism is able to by the poly- magnetic portion 83 of iron core stator 8
Strengthen, according to Ampere's law (screw law), in the range of positive wave, the magnetic in two poly- magnetic portions 83 of two iron core stators 8
Property on the contrary, one end forms N poles, one end forms S poles.Due to magnet, identical charges repel each other that there is a natural attraction between the sexes at this time, as shown in fig. 7, S poles is poly-
Magnetic portion 83 will attract N poles magnet, and push away S poles magnet；The poly- magnetic portion 83 of N poles will attract S poles magnet, and push away N poles magnet,
So that iron core 2 rotates, clockwise as shown in Figure 7 rotates.And when in the range of negative wave, as shown in figure 8, its
Operation principle is similar, and since current direction is reversed, thus the magnetic of poly- magnetic portion 83 will invert, so that iron core 2 is reversed
It rotates, such as rotates counterclockwise.When being persistently passed through positive and negative square wave to coil 7, iron core 2 will in limited angle reciprocating rotary
It is dynamic, so as to drive 1 reciprocating rotation of central rotating shaft.Since 2 rotational angle of iron core is small, high-frequency vibration can be generated, and
It can guarantee that the vibration of generation is stablized.The utility model connects iron core 2 and fixed seat 4, shrapnel 91 and iron core by shrapnel 91
Rotor 2 and the contact surface of fixed seat 4 are big, and its dog-ear 911 is effective against itself torsion, thus solve conventional elastic piece and bullet
The problem of spring is yielding.In addition, the outer housing 5 of the present invention is coated on outside iron core stator 8, not only can effectively protect internal junction
Structure, and its end is open, can quick pairing connection fixing base 4,, can be by shrapnel after one end fixation of shrapnel 91 during assembling
91 are inserted into fixed seat 4, then can be rapidly completed assembling, which reduce assembly difficulty, substantially increase assembling effect.This
The features such as motor of invention simply, is unlikely to deform with assembling, low noise has very strong practicability, preferably widelys popularize.
Although being disclosed by above example to the utility model, the scope of the utility model is not limited to
In this, under conditions of conceiving without departing from the utility model, more than each component can use technical field personnel understand it is similar
Or equivalent element is replaced.
