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 structure between a kind of reinforced two electrode synchronization electromotor rotor poles, especially relate to a kind of structure between the reinforced two electrode synchronization electromotor rotor poles of salient-pole structure non-salient poleization.
Background technology
At present the excitation winding between the salient pole synchronous electric machine rotor pole helps to tighten up by the pole shoe edge by pressing plates sometimes, keeping motor when running up, and the winding conducting wire of the interpolar centrifugal force that reason is not big and flying out.In fact, often there is the lead 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 big more a lot of 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 the 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 lead accident that flies out.The maximum hidden danger of Here it is two utmost point salient pole synchronous electric machine rotor winding fastening structures.
Summary of the invention
Purpose of the present invention be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of be specially adapted to rotating speed ten thousand change and more than structure between the reinforced two electrode synchronization electromotor rotor poles of two utmost point intermediate frequency high-speed synchronous motors.
Purpose of the present invention can be achieved through the following technical solutions: structure between a kind of reinforced two electrode synchronization electromotor rotor poles, this structure comprises rotor, interpolar reinforcement tooth, excitation winding and slot wedge, described excitation winding is wrapped on the 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 the rotor interpolar groove, after the good insulation of pad, squeeze into reinforcing with the interpolar slot wedge again, last dipping lacquer is handled, and makes rotor form a firm integral body.
Described reinforcement tooth comprises tooth top and denticle, described tooth top is the boss shape, described denticle is column, the tooth top protuberance extends to its peripheral excitation winding top with pole shoe or strengthen 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.
Structure comprises the reinforcement tooth between the present invention's two electrode synchronization electromotor rotor poles, 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 handled again at last, makes rotor form a firm integral body.This structure is different from typical non-salient pole structure again.Just between rotor pole, leave 1-3 and strengthen tooth, if necessary, strengthen the facewidth and the tooth top shoulder size of tooth and should under highest running speed, carry out the stress accounting.
Compared with prior art, the present invention has the following advantages:
(1) satisfy under the 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 electric machine rotor winding conducting wires.Be applicable to that more rotating speed is on ten thousand two utmost point intermediate frequency high-speed synchronous motors that change more than reaching.
(2) this structure makes rotor form the integral body that tightens up of a densification after dipping lacquer is handled, and helps the rotor heat radiation.
(3) this structure is different from typical non-salient pole structure, leaves bigger air gap at the interpolar place, favourable ventilation cooling.
Description of drawings
Fig. 1 leaves a rotor structure of strengthening tooth for interpolar;
Fig. 2 leaves three rotor structures of strengthening tooth for interpolar.
Be respectively shown in the 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.
