The stator core of servo motor is walked, including iron core monomer, iron core monomer join end to end to form annular stator, iron core monomer includes arc
Shape plate, copper wire winding post and baffle, are arranged on an end face of arc panel fluted, and it is fixed that the center of groove is vertically installed with
Position block, locating piece is fixedly connected with groove by joining section, is provided with second location hole on locating piece, on the other end of arc panel
Limited block there are two upper and lower parallelly distribute on is set, first positioning hole is provided on limited block, passes through first to determine by positioning pin
Position hole and second location hole, realize the rotation connection between two neighboring iron core monomer.
In another example application No. is 200910130804.2 Chinese invention patent application, disclosed stator core is integrated
A molding magnetizer, the magnetizer surface can coat an insulating layer, with provide reduce whole axial height, simplify it is complicated
The advantages that degree and promotion assembling convenience；The magnetizer additionally comprises a loop portions, several pole teeth and several magnetic pole pieces, the loop portions
With an inner peripheral, the inner peripheral is around an accommodating space is formed, and respectively the pole tooth is respectively provided with a first end and a second end, should
First end connects the inner peripheral of the loop portions, which extends to the accommodating space, and respectively the magnetic pole piece is separately connected the respectively pole
The second end of tooth, therefore the stator core is applicable to the stator structure of inner rotor type motor；Furthermore respectively the pole dental transition can distinguish shape
At an arc guide part, in favor of the progress of winding operation.
Above-mentioned the deficiencies in the prior art are：Core component of the motor as drive system of electric automobile, the quality of performance
Directly determine the performance of vehicle, and the structure of stator core quality directly decides electrical machinery life length, due to slot ripples, climbs
The influence of electrical distance, at stator core both ends, outgoing line part fixed subcoil insulating is easy to damage, and influences coil life；And winding
After wiring is completed, by shaping, have wound stator iron core both ends winding toward iron core middle shrinkage, squeeze, it is easy to cause around
Group is scratched by iron core, impaired so as to cause motor electrical insulation system, during motor overload, is easier to insulation fault occur, very
To being to burn.
Therefore, reinforcing stator core insulation processing in the design phase seems particularly necessary.
Utility model content
In view of the deficienciess of the prior art, the utility model provides a kind of permasyn morot stator core knot
Structure.
The technical solution of the utility model is：A kind of permasyn morot stator core structure, including it is stator end plate, fixed
Sub- punching, punching slot, weld seam slot, stator core and winding, wherein stator punching opens up edge in annular shape on stator punching
The punching slot of the radially uniform distribution of stator punching, stator punching is semi-open slot, and the outside of stator punching is equipped with weld seam slot, fixed
Sub- iron core is stacked by stator punching, and the tooth form of stator end plate is identical as the tooth form of stator punching, and stator end plate is pasted onto fixed
Sub- iron core both ends, winding are wrapped in by punching slot in stator core.
Further, stator punching thickness is 0.35mm, and stator end plate thickness is 0.5mm.
Further, stator punching and stator end plate are completely circular structure.
Further, stator end plate is made of H class F insulating material Fs.
The utility model has the beneficial effects that：In the case where not changing structural material and ensure motor magnetic behavior characteristic
Under acceptance condition, by increasing separately 1 stator end plate at stator core both ends, effectively avoid stator coil being embedded in stator slot
When interior, stator coil is scratched, destroys insulation.Meanwhile increasing the stator end plate of insulation in stator winding and iron core section, it can
To greatly improve insulation effect, the stability of entire motor electrical insulation system is improved, motor is helped to improve and integrally uses the longevity
Life.
