Description of the invention: [Technical field to which the invention belongs] Γ auxiliary bearing; more particularly about a magnetic auxiliary bearing, the saddle system utilizes at least one magnetic shaft in the shaft seat of the motor, and the heart can stably follow the shaft Directional operation, so that the Lai He Ma energy == 丨 axis ~ and the axis [prior art], thinking. Due to the rapid progress of the computer and information industry today, the central processing unit of computing information products has been increasingly recorded, and the amount of heat generated has increased. In order to effectively eliminate heat, the use of heat sinks is now the most basic equipment, and currently the most commonly used There is nothing more than a cooling fan, because it is the most convenient and cheaper. The quality of a cooling fan depends on the operation of the Ryder. The instability of the motor must affect the normal operation of the system or the device. The motor bearing is the key to the quality and stability of the motor. Inside a ball bearing of a general motor, there are usually several spheres. When the bearing is running, the sphere rotates in the bearing housing; however, the bearing is prone to deflect the bearing housing due to centering and tilting, which causes internal travel. Backlash, which in turn affects the operation and performance of the motor, such as vibration, noise, heat generation, power consumption and other shortcomings. Therefore, the publication of the Republic of China Patent No. 535855 discloses an improvement in the structure of a cooling fan, which is composed of a fan blade, a coil group, a circuit board and a bottom plate, wherein the fan blade has a shaft ~ ' _With ball bearings and oil-bearing bearings stacked on top of each other, the Tm parallel ring and G-shaped ring on the two hemps are buckled on the shaft center, which is characterized in that the bottom plate is corresponding to the shaft center and the bottom end. There is a magnetic device, simply by the magnetism and the shaft u, the fan blade is sucked and fixed in the _ fixed position, which can generate a preload on the ball bearing, so that the balls in the ball bearing can run in the same way, in addition, , Because the magnetic device is a healthy axis, it can eliminate the noise of professional students during friction. However, the magnetic device provided by the above-mentioned conventional technology has a flat plate configuration. Therefore, the magnetic land wave device only has a force at the bottom of the upper surface. Obviously, when the fan is running, the axis of the fan ... Disadvantages of producing strange sounds; therefore, it is necessary to improve the disadvantages of the learner. [Summary of the Invention] At this point, in order to solve the disadvantages of the above-mentioned conventional technology, the main purpose of the present invention is to provide a magnetic magnetic lion bearing 'by using a magnetic element on the axis H to produce a magnetic core to make the above magnetic The shaft center maintains stable running in the axial direction, which can reduce the use current. Ben Ming times-purpose, in the secret rotation from the axis to stable operation to reduce noise. A bearing of still another object type of the present invention. The invention is to provide a magnetic auxiliary bearing, which can be applied to various different roots: the present invention = a magnetic auxiliary bearing, which includes at least: a shaft center, a fan f a bearing, a front bearing housing has a plurality of bearings, and a heterogeneous bearing set The axis of the uranium temple can be rotated by the bearing. The above-mentioned wind ^ 1 block has a-hollow strictness-containing space, so that the axis can be located in the sister seat; it is characterized by: [Embodiment] For other advantages, objects, technical features and effects of the present invention, it can be understood through the following detailed description of the preferred embodiment of the present invention in conjunction with the drawings: Please refer to the first figure to show the magnetic auxiliary bearing of the present invention The first preferred embodiment includes: a fan group 10, a motor group 20 and a fan seat 30; the fan group 10 # is composed of a fan hub 11, a shaft center 12, a motor shell 13, The motor core 13 is composed of a magnetic stripe 14 and the shaft center 12 is provided at the center of the bottom of the fan blade hub 11.
