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, have fixing difficulty, the difficult problem of dispelling the heat; For the double-rotor machine that has the unified magnetic field type of permanent magnet on external rotor, inner and outer magnetic field easily influences each other, especially when weak magnetic control is processed.
In the stator permanent-magnet double-rotor machine in recent years proposing, on external rotor without permanent magnet without winding, for double-salient-pole structure, inside and outside motor-field is non-unified magnetic field type, inside and outside motor-field coupling is much smaller than unified magnetic field type double-rotor machine, but inner and outer magnetic field coupling still exists, 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.
The armature spindle of exporting torque in traditional motor is connected with motor lamination armature by rotor field spider, rotor field spider both can transmitting torque, lamination can be fixed and clamped again, and double-rotor machine China and foreign countries internal rotor has internal rotor, the output of the external rotor torque of tubular relies on external rotor end face, and owing to there is no space mounting rotor field spider and rotating shaft, lamination cannot be fixed and clamped, therefore external rotor adopts solid steel material more, cause loss larger.
Summary of the invention
For overcoming the large problem of prior art China and foreign countries rotor loss, reduce inside and outside motor-field coupling, the utility model proposes a kind of be applied to stator permanent-magnet double-rotor machine every magnetic mouse cage outer-rotor structure, and provide torque output end face simultaneously.
The technical solution adopted in the utility model is: the utility model is by external rotor body, non-magnetic, fixedly end ring, output end ring form, external rotor body is the interior outside salient-pole structure that adopts silicon steel laminations to be overrided to form, outside the outside salient pole of rotor body and side salient pole over against yoke mid portion arrange a plurality of along the circumferential direction uniform enclosed slots, in each enclosed slot, be embedded with one non-magnetic; All stretch out outside external rotor body at the two ends of non-magnetic, and the shorter external part place of non-magnetic is fixedly connected with external rotor body with fixing end ring, and the longer external part place of non-magnetic is fixedly connected with external rotor body with output end ring.
The outer-rotor structure the utility model proposes, owing to adopting laminating of lamination and non-magnetic and two end ring fixing, can reduce rotor loss, and non-magnetic the separated magnetic effect also having to a certain degree, and inside and outside motor can independently be controlled; In addition exporting end ring provides the end face of output external rotor torque.

Embodiment
The outer-rotor structure the utility model proposes as depicted in figs. 1 and 2, by external rotor body 1, non-magnetic 2, fixedly end ring 3, output end ring 4 form.
In each enclosed slot, be embedded with one non-magnetic 2, the gap between enclosed slot and non-magnetic 2 welds together with resin filling or with non-magnetic scolder and external rotor body 1, to eliminate the vibration of non-magnetic 2.
All stretch out outside external rotor body 1 at the two ends of non-magnetic 2, at shorter external part 7 places of non-magnetic 2, with fixing end ring 3, be welded and fixed and connect external rotor body 1, at longer external part 8 places of non-magnetic 2, with output end ring 4, be welded and fixed connection external rotor body 1.Output end ring 4 not only can be fixed non-magnetic 2, also can be used as the end face of output external rotor torque.Non-magnetic 2, fixedly end ring 3 and output end ring 4 all adopt non-magnet material.
Operation principle of the present utility model is: by placing non-magnetic 2 in the enclosed slot group 5 on rotor body 1 outside, adopt on the one hand the gap of non-magnetic 2 of resin filling and enclosed slot, or non-magnetic 2 is welded together and come firm non-magnetic 2 with the non-magnetic scolder of external rotor body 1 use, to avoid its vibration, utilize on the other hand fixedly end ring 3 with output end ring 4, non-magnetic 2 two ends to be fixed respectively, utilize this cage-shaped structure to realize the silicon steel laminations 6 of the external rotor body 1 that is fixed and clamped, thereby realize the object that reduces loss.The utility model can reduce the coupling between inside and outside motor-field, increase the reasonability that inside and outside motor is independently controlled, Fig. 4 and Fig. 5 be permanent magnet flux switch dual rotor electric machine outside permanent magnet work independently, Distribution of Magnetic Field figure when interior permanent magnet is not worked, wherein Fig. 4 has adopted common double salient pole outer-rotor structure, under outer permanent magnet effect, there is a small amount of magnetic linkage 11 interior motor of flowing through, Fig. 5 adopts described in the utility model every magnetic mouse cage outer-rotor structure, under outer permanent magnet effect, there is no the magnetic linkage interior motor of flowing through, demonstrate outer magnetic conduction bar 2 and there is certain separated magnetic effect, this is to adopt non-magnet material and face salient pole due to non-magnetic 2, thereby can hold back certain coupling magnetic linkage.The end face of the utility model using output end ring 4 as external rotor torque output, because external rotor is tubular in double-rotor machine, and inner also have an internal rotor, so external rotor can not utilize rotating shaft output torque as the rotor of conventional motors, can only export torque by end face.Output end ring 4 adopts non-magnet material, therefore can not bring brow leakage, can in output end ring 4, be provided with caulking groove in addition, in caulking groove, place output end non-magnetic 2, and non-magnetic 2 is welded together with output end ring 4, improve the Rigidity and strength of output end face.
