Description of drawings:

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is a schematic diagram of the present utility model;

Fig. 2 is the utility model circuit theory diagrams;

Fig. 3 is the schematic diagram of the utility model embodiment.

Embodiment:

See Fig. 1,2, the utility model is a kind of novel motor.Similar with traditional motor configuration, the utility model comprises: rotor 1, stator 2.Its rotor 1 internal fixation has a magnet ring 11 and a rotating shaft 12.Rotor 1 is around these rotating shaft 12 moving or rotations.Stator 2 has four groups of equally distributed coils 21, and the electromagnetic field of coil 21 generations and the magnetic field orthotropic of magnet ring 11.The direction of winding of four coils 21 on the stator 2 alternately changes, and the magnetic direction that promptly adjacent two coils 21 are produced is just opposite.The output 31,32 of two ends access circuit 3 that is used for the lead of coiling 21.Lead in the utility model is a single lead.Certainly, the quantity of above-mentioned employing coil 21 is not four groups yet, for example, and three groups, five groups or other quantity.

As shown in Figure 2, circuit 3 has an IC33 that can change output 31,32 senses of current, and this control chip IC33 has two output OUT1, OUT2, and which output IC33 is exported and the direction of control circuit 3 output currents by by selecting electric current.Simultaneously, this IC33 is connected with one and adjusts the alternately oscillation resistance 34 of output frequency.

Operation principle of the present utility model is: behind the input 31,32 and power connection of circuit 3, circuit 3 is started working.IC in the circuit 3 has two output pin OUT1 and OUT2, and electric current will be alternately by these two output pin outputs.Export when OUT1 has electric current, the output 31 of circuit 3 is anodal, and another output 32 is a negative pole.Otherwise when OUT2 has electric current output, and during the OUT1 no-output, the output 31 of circuit 3 is a negative pole, output 32 just is anodal, the output that is circuit 3 has been realized current reversal, and the electric current on stator 2 coils 21 of flowing through also will change direction, and the magnetic field of its generation changes.If the output current of circuit 3 constantly changes direction under IC control, then the coil 21 on the stator 2 will produce alternating magnetic fields, and the magnet ring 11 that this magnetic field will drive on the rotor 1 12 rotates around the shaft, and constantly continues, rotation is cut off until electric current always.If do not change sense of current in the coil 21 on the stator 2, then the magnetic field of coil 21 just drives rotor 1 in very short time, be that rotor 1 just stops after rotating, have only the continuous change sense of current just can make magnetic field force constantly act on rotor 1, make it continue rotation.The utility model has increased an oscillation resistance 34 before IC33, this oscillation resistance 34 is used for the frequency of the electric current change direction of circuit for regulating and controlling 3.The utility model has adopted the oscillation resistance 34 of scalable resistance, just can change the frequency that IC replaces output current by the resistance that changes oscillation resistance 34, promptly changes the frequency of circuit 3 output current directions.When the resistance increase of oscillation resistance 34, frequencies go lower is rotated slack-off.Otherwise the resistance of working as oscillation resistance 34 diminishes, frequency gets higher, and rotation accelerates.If frequency is positioned at certain numerical value, rotor 1 will not rotate, and just constantly swing in the certain angle scope.This be because since the change of magnetic field force can't form continuous promotion rotor rotation in, promptly magnetic field force does not also drive rotor 1 and revolves and turn around, opposite magnetic field force just makes it change rotation direction, the effect of rotor 1 swing so just occurred.

Just be based on above-mentioned mechanism, the utility model is connected with a jewelry 4 on rotor 1.Jewelry 4 is fixed on the rotor 1, according to different materials, can select bonding, welding or adopt mechanical organ to fix.Drive jewelry 4 by rotor 1 and realize swing.Just be based on above-mentioned operation principle, rotor 1 will drive jewelry fixed thereon 4 and produce swing.As shown in Figure 3, the utility model is applied in the toy pig 5, the tail of this toy pig as with the fixing jewelry 4 of rotor 1, then when the utility model is worked, the tail of toy pig 5 just begins the swing that do not stop, has very much interest.

The utility model is not to realize the swing of jewelry 4 by mechanical driving device, but swings in certain angle by the magnetic drive jewelry 4 that magnetic field produced.Discontinuous, dull situation in the machine driving can not appear in its swing effect nature.

Certainly, the above is an example of the present utility model only, is not to limit the utility model practical range, so, all according to the described structure of the utility model claim, feature, and the equivalence done of principle change or modify, all should be within the utility model application claim.
