The thickness of first permanent-magnetic clamp 411, each first permanent-magnetic clamp 411 is identical as with the thickness of its corresponding second permanent-magnetic clamp 421,
Magnetic force repels each other between each first permanent-magnetic clamp 411 and corresponding second permanent-magnetic clamp 421, to guarantee the stator 41 and institute
State the distance between rotor 42 it is identical when, the magnetic force size between the stator 41 and the rotor 42 is identical so that be located at two
The flywheel 20 keeps stablizing between a Permanent-magnet bearing 40.
In the utility model, the magnetizing direction of the magnetizing direction of first permanent-magnetic clamp 411 and second permanent-magnetic clamp 421
It is axial direction.The magnetizing direction of the second corresponding permanent-magnetic clamp 421 of the magnetizing direction of each first permanent-magnetic clamp 411
It is identical, so that generating repulsion between the stator 41 and the rotor 42 of the radial direction setting of the shaft 30
Effect.Also, the magnetizing direction of first permanent-magnetic clamp 411 of adjacent two by fixing piece (not shown) on the contrary, incited somebody to action
Magnetizing direction is opposite and first permanent-magnetic clamp 411 that radially stacks is fixed together, and can enhance the stator 41
The density of line of magnetic force on surface enhances the magnetic force on 41 surface of stator.Likewise, two adjacent second permanent-magnetic clamps 421

It is dynamic.By enhancing the magnetic force of the stator 41 and 42 surface of rotor, so as in the stator 41 and the rotor 42
Between repulsion while be enough to support 20 stable rotation of flywheel, minimize the big of the stator 41 and the rotor 42
It is small, so as to reduce the size of the Permanent-magnet bearing magnetic bearing-supported flywheel system 100, make Permanent-magnet bearing magnetically levitated flywheel system
System 100 is more suitable for the application of small machines.
Further, the stator 41 includes the first magnetic yoke (not shown), and first magnetic yoke is located at the fixation
Between part and multiple first permanent-magnetic clamps 411, and coats the multiple first permanent-magnetic clamp 411 and remove the surface opposite with the rotor 42
Outer other surfaces make multiple first permanent-magnetic clamps 411 towards the magnetic of 42 side of rotor by first magnetic yoke
Lines of force density enhancing, to enhance the repulsion size between the stator 41 and the rotor 42, thus make the stator 41 with
While repulsion between the rotor 42 meets the needs of supporting 20 stable rotation of flywheel, the described in use few as far as possible
One permanent-magnetic clamp 411 to reduce the size of the stator 41, and then can reduce the volume of the fly wheel system 100.Likewise,
