New description: [New technical field] /, 匕夕丨, (2), especially refers to the number of coils used, reducing the volume of the magnetic bearing, and in order to save energy, In its overall implementation, the application of the innovative structure of the magnetic bearing with the use of the last month ^ more practical and functional characteristics. [Prior Art] Press, due to the high speed, frictionless loss and controllability of the magnetic bearing, it is gradually applied to equipments that require high precision and high speed, such as high-precision optical disc drives and hard discs. Reading device, high-speed turbo molecular vacuum pump, micro-scale milling machine. In the development of magnetic bearing systems, the goal should be to achieve cost savings and volume reduction, and to expand the applicable level. Among them, please refer to the sixth to eighth figures, which are generally common types of magnetic floating bearings (3). The magnetic floating bearing (3) is mainly provided with a stator (31), which is respectively convex on the inner edge of the stator (31). A magnetic pole (311) is arranged, and the magnetic poles (311) are arranged in a Y shape (as shown in the sixth figure) or in an inverse gamma shape (as shown in the seventh figure or in a cross shape). As shown in the figure, a coil (312) is wound around each of the magnetic poles (311), and a rotor (32) is disposed in the stator (31) for operation and use of the magnetic pole (311). The wound coil (312) generates a magnetic force by the magnetic pole (311) by a current to control the rotor (32) to a stable state at a position intermediate the magnetic poles (311) of the stator (31). However, although the above-mentioned magnetic bearing can achieve its intended function, it is found in the actual operation and use that the magnetic bearing is such that the rotor can stably float at the middle of the magnetic poles of the stator, and the coils of the magnetic poles need to be supplied. M285637 is enough current to control the rotor - & consumes power, and because the coil is also needed; it not only generates the magnetic force behind the pole, but also makes the number of turns in the current volume, and let the magnetic bearing There is still room for improvement in the implementation of the enormous space. There are still inconveniences and problems on it [New content] Stator bearing structure (2) 'It is mainly based on the magnetic pole bearing with permanent magnets at the corresponding magnetic pole position, 2 rotor can maintain its floating state, and then use the winding pole Less =, the loop passes a small amount of current to control the floating position of the rotor, so that it does not cost the electric energy, and can also reduce the number of turns of the coil, to achieve the effect of shrinking:: volume' and the overall implementation of the magnetic bearing More practical use: force characteristics. [Embodiment] First, as shown in the first figure, the present invention is mainly composed of a stator and a rotor (2); wherein: the stator (1) is convexly provided with a plurality of magnetic poles (U) on the inner edge of the magnetic pole (11). a coil (12) is disposed around the outer edge, and a rotor (2) is disposed in the stator (1); the main improvement is that the stator (1) is provided with a permanent magnet at a position corresponding to the magnetic pole (11) ( 13). When the magnetic poles (11) of the stator (1) are arranged in a U-shape, the permanent magnets (13) are disposed at two magnetic poles (11) on opposite sides of the upper end of the stator (1) (as shown in the first figure) When the magnetic poles (11) of the stator (1) are arranged in an anti-Υ shape, the permanent magnets (13) are disposed at the magnetic poles (11) corresponding to the middle of the upper end of the stator (1) [such as the second As shown in the figure, when the magnetic poles M285637 (11) of the stator (1) are arranged in a cross, the permanent magnets (13) are disposed at the upper and left magnetic poles (11) of the corresponding stator (1) [ As shown in the third figure, or on the upper and right magnetic poles (11) of the corresponding stator (1) (as shown in the fourth figure), or on the corresponding stator (1) above, below, left and right. Each magnetic pole (11) is as shown in the fifth figure. In this way, the rotor (2) can have a floating force by the permanent magnets (13) of the stator (1) and reuse a small amount of coils (12) on the magnetic poles (11) of the stator (1) to pass a small amount. The current can be stably controlled by the rotor (2) to maintain the float φ in the position to reach the stability of the current. From the above, the composition of the component and the implementation description can be seen that, compared with the conventional use, since the creation is provided with a permanent magnet at the corresponding magnetic pole position of the stator, the permanent magnet is used to make the rotor have a floating force, so that the rotor has a floating force. It not only saves the cost of electric energy, but also reduces the number of turns of the coil, and achieves the effect of reducing the volume thereof, and more practical and effective characteristics in the overall implementation of the magnetic floating bearing. In summary, the present embodiment can achieve the expected use of work efficiency and its specific structure is not only not seen in similar products, nor has it been disclosed before the application, Cheng has fully complied with the provisions of the Patent Law. With the requirement of 'application for new patents according to law', please review and grant patents. < M285637 [Simple description of the diagram] The first diagram: the schematic diagram of the structure of the creation.
