Description

Two magnet type magnetically suspended rotators

Technical field the utility model belongs to a kind of magnetically suspended rotator, is specifically related to the architecture advances of magnetically suspended rotator.

Background technology conventional magnetic levitation whirligig, generally constitute by electromagnet and the suspended substance that contains permanent magnet, suspended substance is positioned at the below of electromagnet, magnet spool flows through electric current and produces magnetic field, inhale mutually with the suspension permanent magnet of the interior upper end of suspended substance in this magnetic field, by the electric current of real-time regulated levitating electromagnet, when being equal in weight of electromagnetic attraction and suspended substance, suspended substance will be suspended in the air; For making suspended substance produce rotation, the bottom is provided with rotating permanent magnet in suspended substance, and the suspended substance below is provided with rotary magnet, by the magnetic force between control rotary magnet and the rotating permanent magnet suspended substance is rotated.The weak point of said structure is: be provided with 4 magnets altogether, the requirement because of its space cooperates makes the assembly work complexity, and has limited the configuration design of this device; Since complex structure, the cost of manufacture height, and rate of finished products is low.

The summary of the invention technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, the two magnet type magnetically suspended rotators that provide a kind of simple and compact for structure, simple and convenient assembly, be easy to moulding, cost of manufacture are low and rate of finished products is high.

The utility model solves the problems of the technologies described above by the following technical solutions: the utility model comprises support, electromagnet and suspended substance, electromagnet links to each other with support, suspended substance is positioned at the below of electromagnet, be provided with the suspension rotor permanent magnet in the suspended substance, the iron core that it is characterized in that described electromagnet is made up of rotatable stator pole core and suspension magnetic pole of the stator iron core, both combine between the higher and lower levels and are one, the rotatable stator pole core is a strip, be combined with rotation mover pole core on the described suspension rotor permanent magnet, it is shaped as strip.

Of the present utility model pair of magnet type magnetically suspended rotator, the iron core of electromagnet is by the rotatable stator pole core and the suspension magnetic pole of the stator iron core be combined into of strip, this electromagnet changes the face symmetric body into by normally used axisymmetric body, simultaneously because the rotation mover pole core on the suspended substance also is a strip, after the energized, in the magnetic attraction that produces vertically, can also produce the turning moment of horizontal direction, when the plane of symmetry of the plane of symmetry of the strip in suspended substance rotation mover pole core and top electromagnet differs an angle, this moment is except the suction of vertical direction, also have a turning moment in the horizontal direction, impel two magnetic symmetry faces to be tending towards overlapping; When different angular deviations, appropriate change current of electromagnet size promptly changes the size of turning moment, can form for a long time along a required net torque of direction rotation, reaches the purpose that makes the suspended substance rotation.Compared with prior art, the utility model cooperates the cooperation that changes 2 magnets into by original 4 magnet spaces, and structure simplifies greatly and compactness, simple and convenient assembly, be easy to moulding, cost of manufacture and have bigger decline, rate of finished products raising, working stability reliable.

Description of drawings

Fig. 1 is the structural representation of conventional magnetic levitation whirligig;

Fig. 2 is a structural representation of the present utility model.

As shown in Figure 1, existing magnetically suspended rotator is by support 5, levitating electromagnet 6, suspended substance 7 consist of, and suspended substance 7 is positioned at the below of levitating electromagnet 6, and suspended substance 7 interior upper ends are provided with suspension permanent magnet Body 8, the coil current flowing of levitating electromagnet 6 also produces magnetic field, this magnetic field and suspended substance 7 interior upper ends Suspension permanent magnet body 8 inhale mutually, by the electric current of real-time adjusting levitating electromagnet 6, suspended substance 7 is suspended In in the air; Suspended substance 7 interior bottoms arrange rotating permanent magnet 9, establish on the base 11 of suspended substance 7 belows Put rotary magnet 10, make outstanding by the magnetic force between control rotary magnet 10 and the rotating permanent magnet 9 Buoyancy aid 7 rotations are got up.

Embodiment as shown in Figure 2, the utility model comprises support 1, electromagnet 2 and suspended substance 3, electromagnet 2 links to each other with support 1, suspended substance 3 is positioned at the below of electromagnet 2, be provided with suspension rotor permanent magnet 4 in the suspended substance 3, the iron core of electromagnet 2 is made up of rotatable stator pole core 21 and suspension magnetic pole of the stator iron core 22, both combine between the higher and lower levels and are one, rotatable stator pole core 21 is a strip, described suspension rotor permanent magnet 4 lower ends are combined with rotation mover pole core 41, and it is shaped as strip.

Operation principle of the present utility model is: the iron core of electromagnet 2 is combined closely up and down by rotatable stator pole core 21 and suspension magnetic pole of the stator iron core 22 and is formed, produce magnetic field after the energized, the suspension suction that suspension magnetic pole of the stator iron core 22 produces along vertical, attract the suspension rotor permanent magnet 4 of setting in the suspended substance 3, electric current by real-time regulated electromagnet 2, when being equal in weight of electromagnetic attraction and suspended substance 3, suspended substance 3 will be suspended in the air; When the plane of symmetry of the plane of symmetry of the strip rotation mover pole core 41 on making suspended substance 3 and the strip rotatable stator pole core 21 of top differs an angle, this moment is except the suction of vertical direction, in the horizontal direction, two magnetic poles of rotatable stator pole core 21 the right and lefts produce turning moment, and it impels two magnetic symmetry faces to be tending towards overlapping.When different angular deviations, the size of appropriate change turning moment can form for a long time and rotate required net torque along a direction, thereby reaches the purpose that makes the suspended substance rotation.

Of the present utility model pair of magnet type magnetically suspended rotator can be applicable to the occasion that various requirements such as handicraft, toy for children, advertisement, teaching aid suspend and rotate.
