Abstract
The utility model discloses a double-salient pole double-squirrel cage outer rotor structure of a stator permanent magnet double-rotor motor. The double-salient pole double-squirrel cage outer rotor structure is composed of an outer rotor body, outer squirrel cage strips, inner squirrel cage strips and end rings. The outer rotor body is an inner and outer double salient pole structure formed by laminating silicon steel sheets. An outer slot group and an inner slot group both composed of multiple through holes evenly distributed in the circumferential direction are punched in the outer rotor body. The through holes of the outer slot group are close to the outer periphery of a yoke part of outer salient poles in the radial direction and are positioned at the tangential central positions of every two adjacent salient poles of the outer salient poles in the tangential direction. The through holes of the inner slot group are close to the inner periphery of a yoke part of inner salient poles and are positioned at the tangential central positions of every two adjacent salient poles of the inner salient poles in the tangential direction. An outer squirrel cage strip is fixedly embedded in each through hole of the outer slot group. An inner squirrel cage strip is fixedly embedded in each through hole of the inner slot group. End parts of the inner and outer squirrel cage strips are fixedly connected with the end rings. The rotor loss is reduced and rigidity and strength are also improved.
Description
Technical field
The utility model relates to a kind of double-rotor machine, and the outer-rotor structure of double-rotor machine specifically belongs to the field of design of electrical motor.
Background technology
The design feature of double-rotor machine is to have a stator and inside and outside two rotors.On the external rotor of most double-rotor machine, all there is permanent magnet, except having fixing difficulty, dispelling the heat difficult problem, also have the easy interactional problem of inner and outer magnetic field.In order to overcome these problems, stator permanent-magnet double-rotor machine has been proposed, on the external rotor of stator permanent-magnet double-rotor machine without permanent magnet without winding, for double-salient-pole structure, inside and outside motor-field is non-unified magnetic field type, but still there is no to solve the problem of inside and outside motor-field coupling, therefore internally outer motor-field execution decoupling zero is to be related to internally outer motor to carry out the independent key of accurately controlling.In double-rotor machine, external rotor is tubular construction, therefore adopt solid steel material more.Owing to can not adopting lamination, cause rotor loss larger.
Summary of the invention
For overcoming the large deficiency of prior art China and foreign countries' rotor loss, the utility model proposes a kind of two mouse cage outer-rotor structures of double-salient-pole that are applied to stator permanent-magnet double-rotor machine.
The technical solution adopted in the utility model is: the utility model is by external rotor body, outer squirrel-cage bar, interior squirrel-cage bar, end ring forms, the inside and outside double-salient-pole structure of external rotor body for being overrided to form by silicon steel laminations, the outer slotted eye group that external rotor body upper punch is comprised of a plurality of through holes by along the circumferential direction uniform and interior slotted eye group, the through hole of outer slotted eye group is the excircle of the yoke portion of close outer salient pole diametrically, on tangentially, be positioned at the tangential centre position of adjacent two salient poles of the evagination utmost point, the through hole of interior slotted eye group is the yoke portion inner periphery of close interior salient pole diametrically, on tangentially, be positioned at the tangential centre position of adjacent two salient poles of the convex utmost point, each through hole of outer slotted eye group is embedded is fixed with an outer squirrel-cage bar, in each through hole of interior slotted eye group, be fixedly embedded with an interior squirrel-cage bar, the end of interior squirrel-cage bar and outer squirrel-cage bar is all fixedly connected with end ring.
The double-salient-pole mouse cage outer-rotor structure the utility model proposes not only can reduce rotor loss, can also improve the Rigidity and strength of double-salient-pole tubular lamination outer-rotor structure.

Embodiment
The two mouse cage outer-rotor structures of double-salient-pole that the utility model proposes as shown in Figure 1, consist of external rotor body 1, outer squirrel-cage bar 2, interior squirrel-cage bar 3, end ring 4.
External rotor body 1 structure as shown in Figure 3, is tubular, for inside and outside double-salient-pole structure, by silicon steel laminations 8, is overrided to form.External rotor body 1 upper punch has two groups of slotted eyes, is respectively that outer slotted eye group 6 and 7, two groups of slotted eyes of interior slotted eye group form by along the circumferential direction uniform a plurality of through holes.The through hole of outer slotted eye group 6 is the excircle 9 of the yoke portion of close outer salient pole 11 diametrically, is positioned at the tangential centre position of two the adjacent salient poles on the evagination utmost point 11 on tangentially.The through hole of interior slotted eye group 7, diametrically near the yoke portion inner periphery 10 of interior salient pole 12, is positioned at the tangential centre position of two the adjacent salient poles on the convex utmost point 12 on tangentially.
As Fig. 1-3, each through hole of outer slotted eye group 6 is embedded with an outer squirrel-cage bar 2, gap is filled up with resin or with non-magnetic scolder, outer squirrel-cage bar 2 and external rotor body 1 are welded together to eliminate the vibration of outer squirrel-cage bar 2, outer squirrel-cage bar 2 ends are coated with insulating material fixing with end ring 4 use nuts 5.Each through hole of interior slotted eye group 7 is embedded with an interior squirrel-cage bar 3, gap is filled up with resin or with non-magnetic scolder, interior squirrel-cage bar 3 and external rotor body 1 is welded together to eliminate the vibration of interior squirrel-cage bar 3, and insulating material fixing with end ring 4 use nuts 5 is coated in interior squirrel-cage bar 3 ends.Outer squirrel-cage bar 2, interior squirrel-cage bar 3 and end ring 4 all adopt non-magnet material.Outer squirrel-cage bar 2 and end ring 4 form outer mouse cage, mouse cage in interior squirrel-cage bar 3 and end ring 4 form.
The through hole of outer slotted eye group 6 can be arranged in yoke portion adjacent, one or more salient poles centre, interval on outer salient pole 11, the through hole of interior slotted eye group 7 can be arranged in the yoke portion adjacent, one or more salient poles centre, interval on interior salient pole 12, this external adjacent middle yoke portion of two salient poles that is furnished with through hole, the number of through hole can be one or more.
Due to interior salient pole 12 or outside the adjacent salient pole of salient pole 11 tangential in side yoke position be set up, radial flux is less and be leakage flux, therefore the outer squirrel-cage bar 2 of placement and interior squirrel-cage bar 3 can reduce the impact of squirrel-cage bar on magnetic circuit to greatest extent herein.Outer squirrel-cage bar 2 and interior squirrel-cage bar 3 both ends all scribble insulating material, prevent that squirrel-cage bar from forming closed-loop path, and cutting magnetic field induces electromotive force when rotated, thereby increases torque pulsation.Outer squirrel-cage bar 2 and interior squirrel-cage bar 3 two ends insulated parts are fixed with end ring 4 use nuts respectively, form two cage-shaped structure with common end.
