Compared with the prior art, the structure has the advantages that: a salient pole structure is hidden, and the structure contributes to radiating the motor rotator and ventilating and cooling the overall motor.
Description
Technical field
The present invention relates to a kind of reinforced two electrode synchronization electromotor rotor interpolar structures, especially relate to a kind of the reinforced two electrode synchronization electromotor rotor interpolar structures of salient-pole structure non-salient pole.
Background technology
At present the excitation winding of salient pole synchronous motor rotor interpolar is by pressing plates, sometimes help to tighten up by the pole shoe edge, and keeping motor when running up, the winding conducting wire of the interpolar centrifugal force that reason is not large and flying out.In fact, often there is the wire accident that flies out to occur.To two utmost point salient pole synchronous electric machines, the motor excitation winding concentrates on the both sides of two utmost points entirely, and again unlike multipolar dynamo, excitation winding also obtains the advantageous effect that interpolar holds around, but is exposed to the periphery fully.Its centrifugal force is more much larger than multipolar dynamo.At this moment the interpolar pressing plate can't help to tighten up by the pole shoe edge, can only be fixed by pressured tight bolt, often the pressing plate of two-pole machine is along on rotor length, and pressure distribution is inhomogeneous, be easy to occur the loosening phenomenon of interpolar winding conducting wire or pressing plate, even cause the wire accident that flies out.The maximum hidden danger of Here it is two utmost point salient pole synchronous motor rotor winding fastening structures.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of rotating speed that is specially adapted to turn and the reinforced two electrode synchronization electromotor rotor interpolar structures of above two utmost point intermediate frequency high-speed synchronous motors ten thousand in order to overcome the defective that above-mentioned prior art exists.
Purpose of the present invention can be achieved through the following technical solutions: a kind of reinforced two electrode synchronization electromotor rotor interpolar structures, this structure comprises rotor, interpolar reinforcement tooth, excitation winding and slot wedge, described excitation winding is wrapped on rotor, be provided with the reinforcement tooth between the pole shoe of described rotor, the pole shoe of described rotor is provided with the interpolar slot wedge with the reinforcement between cog, excitation winding is directly moved in rotor interpolar groove, after the good insulation of pad, squeeze into reinforcing with the interpolar slot wedge again, last dipping lacquer is processed, and makes rotor form a firmly integral body.
Described reinforcement tooth comprises tooth top and denticle, described tooth top is boss-shaped, described denticle is column, the tooth top protuberance extends to its peripheral excitation winding top with pole shoe or strengthens forming between the tooth denticle wedge groove, described interpolar slot wedge be positioned at excitation winding outer by the wedge groove of strengthening forming between tooth tooth top and pole shoe or reinforcement tooth denticle.
Described reinforcement tooth is provided with 1-3.
The present invention's two electrode synchronization electromotor rotor interpolar structures comprise the reinforcement tooth, excitation winding and interpolar slot wedge, described reinforcement tooth is between two excitation winding, described excitation winding should directly move in the groove of interpolar, described interpolar slot wedge is squeezed into described excitation winding after the good insulation of pad and is tightened up, dipping lacquer is processed again at last, makes rotor form a firmly integral body.This structure is different from again typical non-salient pole structure.Just leave 1-3 and strengthen tooth between rotor pole, if necessary, strengthen the facewidth and the tooth top shoulder size of tooth and should carry out the stress accounting under highest running speed.
Compared with prior art, the present invention has the following advantages:
(1) satisfy in situation when slot wedge and the facewidth and the tooth top shoulder stress of strengthening tooth, this structure can be guaranteed not reason centrifugal force and flying out of two utmost point salient pole synchronous motor rotor winding conducting wires.More be applicable to rotating speed ten thousand turn and above two utmost point intermediate frequency high-speed synchronous motors on.
(2) this structure after dipping lacquer is processed, makes rotor form the integral body that tightens up of a densification, is conducive to the rotor heat radiation.
(3) this structure is different from typical non-salient pole structure, and the place leaves larger air gap at interpolar, and favourable ventilation is cooling.
Description of drawings
Fig. 1 is that interpolar leaves a rotor structure of strengthening tooth;
Fig. 2 is that interpolar leaves three rotor structures of strengthening tooth.
Be respectively shown in number in the figure:
1 for strengthening tooth, and 2 is excitation winding, and 3 is the interpolar slot wedge.
Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment 1
as shown in Figure 1, a kind of reinforced two electrode synchronization electromotor rotor interpolar structures, this structure comprises rotor and excitation winding 2, described excitation winding 2 is wrapped on rotor, be provided with one between described rotor and strengthen tooth 1, strengthen tooth 1 and comprise tooth top and denticle, described tooth top is boss-shaped, described denticle is column, the tooth top protuberance extends to its peripheral excitation winding 2 tops and pole shoe or strengthens forming between tooth 1 denticle the wedge groove, be provided with interpolar slot wedge 3 between the pole shoe of described rotor and reinforcement tooth 2, interpolar slot wedge 3 be positioned at excitation winding outer by the wedge groove of strengthening forming between tooth tooth top and pole shoe or reinforcement tooth denticle.Excitation winding 2 is directly moved in rotor interpolar groove, after pad insulate well, then take with the interpolar groove and squeeze into reinforcing, last dipping lacquer is processed, and makes rotor form a firmly integral body.
Said structure is used on efficient special-purpose two utmost point no-brush synchronous generators of FWL24 type, and it is special that this motor requires, and at first requires efficient, exceed 5 percentage points than common electric efficiency, the rotor winding electric is close lower, therefore the rotor copper consumption is more, the rotor copper quality is large, its centrifugal force is increased a lot.Moreover, require motor can bear the nonlinear load of 45% rated power and do not cause vibration, this just requires motor can suppress very high subharmonic impact.Corresponding requirements motor magnetic is close can not be too saturated, therefore rotor length increases to some extent, this is tightening up of unfavorable rotor winding interpolar also.Adopted Fig. 1 structure, because the protuberance of strengthening tooth extends to the excitation winding top, and take strengthening being provided with the interpolar groove below tooth on excitation winding, make whole rotor form an integral body, accident loosening or that wire flies out can not appear yet even therefore motor rotor speed is very high.Rotor is solid and reliable, constructs also uncomplicated, produces and with being satisfied with per family.
