Abstract
The utility model discloses a 200kW tombarthite permanent magnet generator stator is towards piece, including the lamellar body, the middle part of lamellar body be equipped with with rotor core complex round hole, lamellar body limit portion is provided with the cramp groove, the equipartition has 36 coil grooves on the lamellar body of round hole outer lane, the coil groove is the T type, and the width of rebate in coil groove is 6mm, forms T molded lines circle tooth between the adjacent coil groove, minimum perpendicular distance between the adjacent coil groove is 9mm. Since the technical scheme is used, this stator has adopted the close design of high tooth magnetism of 36 coil grooves and coil tooth towards the chip layout, to the condition of solving the reflection of the high armature of the high -power tombarthite permanent magnet generator of 200kW, the volume can be little more a lot of than send out the size of the electric machine with the power excitation during towards the chip layout for this stator, and the notch design is 6mm, rule technology has been optimized, though can increase the reactance slightly, nevertheless the armature reflection can be optimized to the population parameter, reduce the motor demagnetizing effect, the efficiency of the generator electricity generation is improved.
Description
Technical field
This utility model relates to a kind of generator component, particularly a kind of 200kW rare-earth permanent-magnet power generator stator punching。
Background technology
Generator unit stator is made up of stator core, stator winding and support three part, and wherein stator core is formed by high permeability material punching overlapping combinations。The structure of punching directly affects the assembling production efficiency etc. of the efficiency of electromotor, life-span, performance and motor。
But in prior art, the high-power rare earth permanent-magnetic generator of 200kW is due to stator structure problem, the situation that high armature reflects often occurs, reduces the generating efficiency of motor。
Utility model content
The purpose of this utility model is just to provide a kind of armature reflection that can optimize electromotor, reduces the 200KW rare-earth permanent-magnet power generator stator punching of electromotor demagnetizing effect。
The purpose of this utility model is realized by such technical scheme: a kind of 200kW rare-earth permanent-magnet power generator stator punching, including lamellar body, the middle part of described lamellar body is provided with the circular hole coordinated with rotor core, described lamellar body edge is provided with cramp groove, being evenly equipped with 36 coil grooves on the lamellar body of described circular hole outer ring, described coil groove is T-shaped, and the width of rebate of coil groove is 6mm, forming T-shaped coil tooth between adjacent coil groove, the minimum perpendicular distance between described adjacent coil groove is 9mm。
Further, the angle between axis and the axis of coil tooth of described adjacent coil groove is 5 degree。
Preferably, the ratio of described lamellar body exradius and circular hole inner circle radius is 1.5。
Owing to have employed technique scheme, this utility model has the advantage that
This stator punching has been designed with the high close design of tooth magnetic of 36 coil grooves and coil tooth, for the situation solving the high-power rare earth permanent-magnetic generator height armature reflection of 200kW, during the design of this stator punching, volume can be less much than same power excitation generator volume, and notch design is 6mm, optimize wire insertion technology, although can slightly increase reactance, but population parameter can optimize armature reflection, reduce motor demagnetizing effect, improve electrical power generators efficiency。
Other advantages of the present utility model, target and feature will be illustrated to a certain extent in the following description, and to a certain extent, will be apparent to those skilled in the art based on to investigating hereafter, or can be instructed from practice of the present utility model。Target of the present utility model and other advantages can be realized by description below and claims and obtain。
Accompanying drawing explanation
Accompanying drawing of the present utility model illustrates as follows:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the A place enlarged drawing in Fig. 1。
In figure: 1. lamellar body；2. circular hole；3. cramp groove；4. coil groove；5. coil tooth。
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail。
As depicted in figs. 1 and 2, a kind of 200kW rare-earth permanent-magnet power generator stator punching of this city embodiment, including lamellar body 1, the middle part of described lamellar body 1 is provided with the circular hole 2 coordinated with rotor core, described lamellar body 1 edge is provided with cramp groove 3, the lamellar body 1 of described circular hole 2 outer ring is evenly equipped with 36 coil grooves 4, described coil groove 4 is T-shaped, the width of rebate of coil groove 4 is 6mm, optimize wire insertion technology, T-shaped coil tooth 5 is formed between adjacent coil groove 4, minimum perpendicular distance between described adjacent coil groove 4 is 9mm, when enabling this stator punching to design, volume is less much than same power excitation generator volume, and optimize armature reflection, reduce motor demagnetizing effect, make electrical power generators in hgher efficiency。
As the improvement of the present embodiment, the angle between axis and the axis of coil tooth 5 of described adjacent coil groove 4 is 5 degree。
As the improvement to the present embodiment, the ratio of described lamellar body 1 exradius and circular hole 2 inner circle radius is 1.5, and its dimensional structure can guarantee that stator core occurs without magnetic saturation problem, and makes stator volume sufficiently small, makes lower in cost。
What finally illustrate is, above example is only in order to illustrate the technical solution of the utility model and unrestricted, although this utility model being described in detail with reference to preferred embodiment, it will be understood by those within the art that, the technical solution of the utility model can be modified or equivalent replacement, without deviating from objective and the scope of the technical program, it all should be encompassed in the middle of right of the present utility model。
