Abstract
The invention discloses an inner-tooth-shaped octopole stator magnetic core, comprising an annular body and eight stator teeth which are uniformly distributed on the inner circumference of the annular body, wherein the section of each stator tooth is rectangular. The width of a tooth groove root (a part which is close to the inner circumference of the annular body) is 3-6 times as much as the width of each stator tooth. Therefore, a larger tooth groove area is formed. An iron core material and a winding material are conveniently mounted. A tooth groove of the inner-tooth-shaped octopole stator magnetic core has a larger section area so that more winding coils can be contained and the performance of a motor can be easily improved.
Description
Technical field
The present invention relates to a kind of magnetic suspension motor parts, relate in particular to the stator core in a kind of magnetic suspension motor.
Background technology
Magnetic suspension motor (magnetic floats motor, magnetic motor) is a kind of motor of new structure, and motor itself both can produce torque, can produce again the magnetic suspension force of support rotor, makes rotor can realize machinery-free friction rotation.
Stator in the magnetic suspension motor generally comprises stator core and winding, and stator core is formed by sintering magnetic materials, and with stator tooth, is the teeth groove for the placement winding between the adjacent stators tooth.
Therefore the shape of stator core and the distribution mode of teeth groove have certain impact to the performance of magnetic suspension motor, need to constantly seek better mode, the purposes such as, lifting motor performance easy to process to realize.The teeth groove sectional area of more existing stator cores is less, and open ended winding is limited.
Summary of the invention
The invention provides a kind of stator core long-pending than the canine tooth slot cross-section that have.
A kind of inner-tooth-shaped octupole stator magnetic core, eight stator tooths that comprise annular solid and be evenly distributed on the annular solid inner periphery, the cross section of described stator tooth is rectangle.
Described cross section is teeth groove between the adjacent stator tooth perpendicular to the axis of stator core.
As preferably, the width of described teeth groove root (press close to annular solid inner periphery position) is 3～6 times of stator tooth width.Can have so larger teeth groove area.Be convenient to the installation of core material and winding material.
Described inner-tooth-shaped octupole stator magnetic core is structure as a whole on the whole, is formed by sintering magnetic materials, all can adopt prior art with regard to material itself and the moulding process of stator core.
The teeth groove of inner-tooth-shaped octupole stator magnetic core of the present invention has larger sectional area, can hold more winding coil, is beneficial to the performance of lifting motor.
Description of drawings
Fig. 1 is the structural representation of stator core of the present invention;
Fig. 2 is stator core among Fig. 1 schematic diagram after in conjunction with winding coil.
Embodiment
Referring to accompanying drawing, a kind of inner-tooth-shaped octupole stator magnetic core of the present invention, eight stator tooths 1 that comprise annular solid 2 and be evenly distributed on annular solid 2 inner peripherys, the cross section of stator tooth 1 (perpendicular to the cross section of the axis of stator core) is rectangle, is teeth groove between the adjacent stator tooth.
The width of teeth groove root (press close to annular solid inner periphery position) is 4 times of stator tooth width, can have so larger teeth groove area.Be convenient to the installation of core material and winding material.
Inner-tooth-shaped octupole stator magnetic core is structure as a whole on the whole, is formed by sintering magnetic materials, all can adopt prior art with regard to material itself and the moulding process of stator core.
Visible adjacent windings connects in pairs among Fig. 2, so that magnetic is strengthened.A pair of coil is in same magnetic circuit, and its self-induction is about 4 times an of coil, has also reduced half with the bridge resistance, number of its pairing, is barricaded as bridge circuit without each coil distribution resistance, and the line work amount also can be very large like that.It is NNSSNNSS that combination requires the order of magnetic pole, can eliminate the coupling between different magnetic circuits.The interpolar angle is 45 °, the restoring force that the utmost point the more produces and rigidity with respect to interference radiating way more evenly, simultaneously concerning each actuating coil, the length of magnetic path that causes in the stator yoke of arc and rotor yoke is shorter, leakage field is also little.
The teeth groove of stator core of the present invention has larger sectional area, can hold more winding coil, is beneficial to the performance of lifting motor.
Claims (2)
1. inner-tooth-shaped octupole stator magnetic core, eight stator tooths that comprise annular solid and be evenly distributed on the annular solid inner periphery is characterized in that the cross section of described stator tooth is rectangle.
2. inner-tooth-shaped octupole stator magnetic core as claimed in claim 1 is characterized in that, the width of described teeth groove root is 3～6 times of stator tooth width.
