The effective magnetic flux of the magnetic shoes 126, 128 facing the magnetic pole of the rotor is significantly weakened by a considerable distance from the position where the central column 126 is wound with the coil 124, so that the energy utilization efficiency is greatly reduced. In addition, since the magnetic force is distributed in the direction of the central column 122 and the magnetic shoes 126, 128, "the stator is fixed to the direction of attraction of the rotor, and such attraction will cause the rotor to tend to be skewed. When the coil assembly is rotated, it will The rotor is rotated in different directions to cause vibration, which not only damages the life of the rotor, but also refers to the rotational efficiency. s can fully utilize the magnetic flux lines of the magnetic leakage to improve the performance of magnetic energy when the energy is not increased; and the smooth running along the frame axis when the magnetic energy is running, reducing the unnecessary pivot of the stepping motor Centrifugal vibration; make the stepper motor run more prolonged. ~ [New content] Therefore, one of the new types of stepping motors. In order to provide a quiet stepping motor, it is another object of the present invention to provide a type of vibration reducing friction that reduces magnetic leakage energy and to reduce vibration and friction. A further object of the present invention is to provide a stepper motor with an energy recovery rate of one liter. M320250 Another purpose of this new type is to increase the length of the operation of the stepping horse: reduce the number of parts of the brakes. The new type of stator has two auxiliary yoke parts stepping one for the rotation of a pivot ...to, 匕3 · — The rotor table Φ η has a complex number along the radial direction of the (four) thousand surface, and the neighbors are magnetically opposite, etc.; the stator, ~ · pole, each of the magnetic pole spacing is in the range of An iron core, with twenty-eight witnesses, a soil carving + a knife, a body, and the main ir, such as the main yoke; the two corresponding, β σ, located in the main magnetic parts Keep away from ^^^, 古一也#丄1遂从δ海# The body side, and has /, the main yoke part of the magnetic shoe clip pairs even number of wire support „ part of the magnetic boots, and ..., ... / pole spacing The main magnetic vehicle ... ~ the part of the magnetic shoe clip corresponds to a distance of the magnetic poles = the auxiliary magnetic head portion of the magnetic track; and the second set of coils respectively disposed on the main magnetic vehicle body. By the configuration of the auxiliary magnetic vehicle portion , so that the magnetic energy that is expected to escape can be charged and used, and the combined magnetic force and the main magnetic vehicle are combined and multiplied. Under the lock condition, the energy consumption can be reduced and the rotor rotation efficiency can be improved. Conversely, the °Xizhou deflection attraction reduces the vibration energy consumption and the friction of the bearing part, which fully achieves the new purpose. The technical content, features, and advantages of the present invention will be apparent from the following description of the preferred embodiments illustrated herein. FIG. 3 shows a stepping motor of the stator with two auxiliary magnetic parts, which mainly comprises a permanent magnet rotor 5 and an outer stator. In this example, the rotor 5 selects an 18-pole rotor, and its ν, The s magnetic poles are spaced apart along a M320250 area and are radially disposed on the outer side facing the rotor 5. Therefore, in the figure and the following calculations, each magnetic pole accounts for about 20. (360./18=20.) The stator of the present example has an iron core 6, and the iron core 6 is provided with two main yoke portions 62, two auxiliary magnetic peach portions 64 and a high magnetoresistive portion 66, and the main yoke portion 62 and the auxiliary magnetic motor portion 64. Correlation is the connection between the main yoke portion 62 and the rotor pivot 52 And the auxiliary yoke portion 64 and the rotor pivot 52 are connected with an obtuse angle; the two main magnetic light portions 62 are different from the magnetic poles of the rotor 5, for example, when the main magnet portion corresponds to the rotor 5N or s pole, the other main magnetic The yoke portion corresponds to the buffer between the rotor 5 and the S pole, so that when the two coil groups are alternately enabled, the rotor 5 is smoothly rotated, and the high magnetoresistive section % is already empty when the stator is fabricated. Rolling space to reduce magnetic energy dissipation. As described in the prior art, the magnetic leakage phenomenon will occur after the coil is energized, as shown in Figure 4. The ideal magnetic field line distribution is expected to be as thick as the dotted line ^ 'complete line _ core' However, in fact, the magnetic flux distribution has a considerable proportion of two: as shown by the thin f-line, along the core 6 and other paths in the vicinity, and thus distributed; the circumference of the iron β and the auxiliary yoke circuit. The auxiliary magnetic 扼 part of the magnetic ΪΓ type, that is, the recycled part of the publication should be dissipated: the second application attracts the magnetic pole of the permanent magnet rotor; as shown in Fig. 5, the body of the magnetic pole of the magnetic pole fork and the magnetic rail attract, when sucking ... attracting the rotor of the auxiliary yoke part ^ ^ ^ ^ ^ ^ ^ F2, the combined force of the two attractive forces = 7 light part of the two wires with suction iF φ ^ , ',, because of the "main magnet part of the fish rotor 柘 axis connection And "the auxiliary yoke portion and the rotor /, the pure angle, so that the F2 /, αα connection" angle 0 is thus the second component: the reverse component of the offset with F1, the resultant force -. This means that the rotor skew caused by the resultant force M320250 is reduced, and the vibration and noise are reduced. The bearing wear is slowed down, and the motor life is from the aspect of the heart. The moment caused by the heart (1) is the same as the moment caused by the torque (for example, both clockwise directions). The torque is increased, which is more than the original! The torque of Γ2 is more efficient even if the energy of the energy is the same. * However, as can be easily understood by those skilled in the art, the structure of the present invention is not limited to the inner rotor motor, and can be easily converted to the outer rotor motor, so that the stator 84 is disposed on the outer rotor 82 as shown in the figure. In the state of high reluctance section, the outer rotor 82 has eighteen staggered magnetic poles, and the two main magnetic parts are different from each other, and the main magnetic parts correspond to the outer rotor magnetic poles and the other main yokes. The portion corresponds to the buffer of the outer rotor pole 826; the main magnet portion 842 and the auxiliary magnetic light portion 844 still maintain a pure angle, which effectively utilizes the magnetic energy dissipated after the coil 8424 is enabled, and reduces the vibration caused by the resultant force ^ And the wearer. The above is only the preferred embodiment of the present invention. When it is not possible to limit the scope of the implementation of the present invention, it is simple to use the scope of the present invention: the scope of interest and the description of the new type (4) The effect changes and repairs should still be within the scope of this new patent.
