Description
Technical field
The present invention relates to the outer-rotor structure of a kind of double-rotor machine, specifically double-rotor machine, belong to the field of design of electrical motor.
Background technology
Being structurally characterized in that of double-rotor machine has a stator and inside and outside two rotors.All there is permanent magnet on the outer rotor of most double-rotor machine, except there is fixing difficulty, dispelling the heat in addition to the problem being difficult to, there is also the easy interactional problem of inner and outer magnetic field.In order to overcome these problems, propose stator permanent-magnet double-rotor machine, without permanent magnet without winding on the outer rotor of stator permanent-magnet double-rotor machine, for double-salient-pole structure, inside and outside motor-field is non-unified magnetic field type, but can the problem the most not solving the coupling of inside and outside motor-field, the execution decoupling of outer motor-field be therefore to be related to carry out the independent key accurately controlled by outer motor.In double-rotor machine, outer rotor is tubular construction, therefore uses single solid steel material more.Owing to lamination can not be used, cause rotor loss bigger.
Summary of the invention
For overcoming the deficiency that prior art China and foreign countries rotor loss is big, the present invention proposes a kind of double mouse cage outer-rotor structure of double-salient-pole being applied to stator permanent-magnet double-rotor machine.
The present invention uses the technical scheme to be: the present invention is by outer rotor body, outer squirrel-cage bar, interior squirrel-cage bar, end ring is constituted, outer rotor body is the inside and outside double-salient-pole structure being overrided to form by silicon steel laminations, outer rotor body upper punch is by the outer slotted eye group formed by the most uniform multiple through holes and interior slotted eye group, the through hole of outer slotted eye group is diametrically near the excircle in the yoke portion of outer salient pole, the tangential centre position of adjacent two salient poles of evagination pole it is positioned on tangential, the through hole of interior slotted eye group is diametrically near the yoke portion inner periphery of interior salient pole, the tangential centre position of adjacent two salient poles of convex pole it is positioned on tangential, each through hole of outer slotted eye group is embedded is fixed with an outer squirrel-cage bar, fix in each through hole of interior slotted eye group and be embedded with an interior squirrel-cage bar, the end of interior squirrel-cage bar and outer squirrel-cage bar is fixedly connected with end ring.
The double-salient-pole mouse cage outer-rotor structure that the present invention proposes is possible not only to reduce rotor loss, it is also possible to improve rigidity and the intensity of double-salient-pole tubular lamination outer-rotor structure.

Detailed description of the invention
The double mouse cage outer-rotor structure of the double-salient-pole that the present invention proposes is as it is shown in figure 1, be made up of outer rotor body 1, outer squirrel-cage bar 2, interior squirrel-cage bar 3, end ring 4.
Outer rotor body 1 structure, as it is shown on figure 3, be tubular, for inside and outside double-salient-pole structure, is overrided to form by silicon steel laminations 8.Outer rotor body 1 upper punch has two groups of slotted eyes, is outer slotted eye group 6 and interior slotted eye group 7 respectively, and two groups of slotted eyes are by the most uniform multiple through holes composition.The through hole of outer slotted eye group 6 is diametrically near the excircle 9 in the yoke portion of outer salient pole 11, the tangential centre position of adjacent two salient pole being positioned on evagination pole 11 on tangential.The through hole of interior slotted eye group 7 is diametrically near the yoke portion inner periphery 10 of interior salient pole 12, the tangential centre position of adjacent two salient pole being positioned on convex pole 12 on tangential.
Such as Fig. 1-3, each through hole of outer slotted eye group 6 is embedded with an outer squirrel-cage bar 2, being filled up by gap resin or weld together to eliminate the vibration of outer squirrel-cage bar 2 by outer squirrel-cage bar 2 and outer rotor body 1 with non-magnetic solder, outer squirrel-cage bar 2 end is coated with insulating materials and fixes with end ring 4 nut 5.Each through hole of interior slotted eye group 7 is embedded with an interior squirrel-cage bar 3, gap resin fills up or welds together with the vibration of squirrel-cage bar 3 in eliminating with non-magnetic solder by interior squirrel-cage bar 3 and outer rotor body 1, and interior squirrel-cage bar 3 end is coated insulating materials and fixes with end ring 4 nut 5.Outer squirrel-cage bar 2, interior squirrel-cage bar 3 and end ring 4 all use non-magnet material.Outer squirrel-cage bar 2 and end ring 4 form outer mouse cage, and interior squirrel-cage bar 3 and end ring 4 constitute interior mouse cage.
The through hole of outer slotted eye group 6 may be arranged at yoke portion adjacent, that be spaced one or more salient pole centre on outer salient pole 11, the through hole of interior slotted eye group 7 may be arranged at the yoke portion adjacent, that be spaced one or more salient pole centre on interior salient pole 12, yoke portion in the middle of these external two adjacent salient poles being disposed with through hole, the number of through hole can be one or more.
Due to the Adjacent salient poles at interior salient pole 12 or outer salient pole 11 tangentially on E Bu position, side, radial flux is less and be leakage magnetic flux, therefore places outer squirrel-cage bar 2 herein and interior squirrel-cage bar 3 can reduce the squirrel-cage bar impact on magnetic circuit to greatest extent.Outer squirrel-cage bar 2 and interior squirrel-cage bar 3 both ends all scribble insulating materials, prevent squirrel-cage bar from forming closed-loop path, and cutting magnetic field induces electromotive force when rotated, thus increases torque pulsation.Outer squirrel-cage bar 2 and interior squirrel-cage bar 3 two ends insulated part are fixed with nut with end ring 4 respectively, form double cage-shaped structure with common end.
