Abstract

The utility model discloses a detachable low-speed large-torque permanent-magnetic motor stator structure which comprises stator pressure plates, stator sector punching sheets and stator connecting pins. Each of the stator pressure plates and the stator sector punching sheets is equipped with corresponding through holes. The motor stator structure is formed by that multiple stator sector punching sheets are assembled, the stator pressure plates are arranged at the two sides of the end portion of the stator sector punching sheets to compress the stator punching sheets, and the stator connecting pins penetrate through the corresponding through holes in the stator pressure plates and the stator sector punching sheets to fix the motor stator structure. The detachable low-speed large-torque permanent-magnetic motor stator structure of the utility model is high in structural rigidity and low in production cost.

Description

A kind of assemble type low speed large torque moment permanent-magnet motor stator structure
Technical field
The utility model relates to motor technology field, particularly a kind of assemble type low speed large torque moment permanent-magnet motor stator structure.
Background technology
In recent years, the progressively maturation of magneto research and development experience, through wideling popularize and apply existing achievement in research, makes magneto at aspects such as national defence, industrial and agricultural production and daily lifes, obtain application more and more widely.Because magneto adopts permanent magnet excitation, be easy to realize multipole, and within the scope of very wide load factor, can keep higher efficiency and power factor characteristic, have the incomparable advantage of asynchronous machine.
The stator structure of current high rotating speed permanent magnet synchronous motor, main according to designer's different designs theory, stator grooved be take the grooveds such as peariform slot, T-shaped groove as main.But the too little motor stator coil difficulty that causes of notch, often, because workman's operational issue causes the problems such as motor turn-to-turn short circuit, affects motor quality.Because motor span is very large, cause motor stator end very long, it is severe that the motor feels hot simultaneously; The low speed large torque moment permanent-magnet motor project organizations that adopt multipole few groove, stator mostly is opening rectangular channel, and motor stator winding span is 1, has effectively solved the problem that stator end is long, rule is difficult more.But because the stator yoke portion of multipole few groove structure is narrow, especially large diameter stator, full wafer punching press, causes stator integral rigidity too poor after having laminated, and distortion is severe, and if while adopting full circle punching press, waste of material is more serious, cost increases.
Utility model content
The purpose of this utility model is to overcome existing above-mentioned deficiency in prior art, and a kind of good rigidity, assemble type low speed large torque moment permanent-magnet motor stator structure that production cost is low are provided.
In order to realize foregoing invention object, the technical solution adopted in the utility model is:
A kind of assemble type low speed large torque moment permanent-magnet motor stator structure, comprise stator pressing plate, stator segmental punching and stator connecting pin, on described stator pressing plate and stator segmental punching, be respectively equipped with corresponding through hole, this motor stator structure forms by some described stator segmental punchings are assembled, described stator pressing plate is set in both sides, described stator segmental punching end after assembled completing and compresses the assembled motor stator structure of some described stator segmental punchings, finally with stator connecting pin, through the corresponding through hole on described stator pressing plate and stator segmental punching, fix this motor stator structure.
Described stator connecting pin two ends are welded on described stator pressing plate.
Described stator segmental punching is provided with a plurality of opening rectangular channels.
compared with prior art, the beneficial effects of the utility model:
In the utility model, adopt the assembled motor stator structure of some stator segmental punchings, there is good manufacturability, significantly reduced the production cost of stator punching; Motor stator structure adopts stator connecting pin to fix, and effectively raises the rigidity of motor stator.
accompanying drawing explanation:
Fig. 1 is the axial cutaway view of the overall structure of stator in the utility model.
Fig. 2 is the stator segmental punching structure chart in Fig. 1.
Fig. 3 is the A-A cutaway view of Fig. 1.
Reference numeral: 1-stator pressing plate, 2-stator connecting pin, 3-stator segmental punching.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail.But this should be interpreted as to the scope of the above-mentioned theme of the utility model only limits to following embodiment, all technology realizing based on the utility model content all belong to scope of the present utility model.
Embodiment
As Figure 1-3, a kind of assemble type low speed large torque moment permanent-magnet motor stator structure of the present embodiment, comprise stator pressing plate 1, stator segmental punching 3 and stator connecting pin 2, on described stator pressing plate 1 and stator segmental punching 3, be respectively equipped with corresponding through hole, this motor stator structure forms by some described stator segmental punchings 3 are assembled, described stator pressing plate 1 is set in described stator segmental punching 3 both sides, end after assembled completing and compresses the assembled motor stator structure of some described stator segmental punchings 3, finally with stator connecting pin 2, through the corresponding through hole on described stator pressing plate 1 and stator segmental punching 3, fix this motor stator structure.By stator connecting pin 2, a plurality of stator segmental punchings 3 are fixed into integral body, can guarantee the rigidity of motor stator.Described stator connecting pin 2 two ends are welded on described stator pressing plate 1, have increased the mechanical strength of stator integral body.Described stator segmental punching 3 is provided with a plurality of opening rectangular channels, and winding span is 1, and stator built-in line has good manufacturability, can be good at guaranteeing motor quality.The utility model is by changing the version of common permanent magnet motor stator, assembled by some stator segmental punchings, after assembled completing, with stator pressing plate, compress, finally with connecting pin, be fixed, to realize good manufacturability, significantly reduce the production cost of stator punching simultaneously.
Concrete, the stator pressing plate of some 1 and stator segmental punching 3 are connected and overlapped together with connecting pin 2 by the positioning through hole above it.After having laminated, the two ends of connecting pin 2 and stator pressing plate 1 are welded together.The utility model has the advantages that stator adopts some stator segmental punchings assembled, there is good manufacturability, significantly reduced the production cost of stator punching simultaneously; Stator adopts stator connecting pin to fix, and effectively raises the rigidity of motor stator.
By reference to the accompanying drawings embodiment of the present utility model is had been described in detail above, but the utility model is not restricted to above-mentioned execution mode, in the spirit and scope situation of claim that does not depart from the application, those skilled in the art can make various modifications or remodeling.
