In the present embodiment, stator body is formed by step-feeding decompressor continuous punching on the silicon steel sheet of band shape, and stator body is struck out circle, then the silicon steel sheet between two stator bodies just stamps out the rotor silicon steel sheet of two 755 motors;
The aperture of coiling location hole is arranged to suitable with the rotor silicon steel sheet diameter of 755 motors, after punching press, the blank that silicon steel sheet stamps out in the position of coiling location hole also be may be used for the rotor being processed into 755 motors further, such punching press distributing mode, Appropriate application silicon steel sheet resource, reduces production cost.
And relative to the stator body under conventional situation, the aperture of coiling location hole increases in the present embodiment, just in time reduces the iron consumption amount of stator, reduce iron core cutter degree, make motor consume the copper iron of material than more rational.
Further, the ratio of width to height of shown teeth groove is 0.55 ~ 0.57.
Select the ratio of width to height in this number range, as when the facewidth of teeth groove is 7.6mm, tooth depth is chosen as 13.5mm, and when copper consumption is equal, the number of turn of coil increases, the copper factor of teeth groove improves, motor winding terminal resistance is reduced, and copper loss also reduces thereupon, thus improves electric efficiency and reduce temperature rise, too increase torque density, improve motor performance.
Further, the top of the described stator body between adjacent sheaves is provided with the auxiliary flute formed to stator center indent.
The torque that when cogging torque is magneto winding no power, permanent magnet produces with the interphase interaction of iron core is caused by the tangential component of the Interaction Force of permanent magnet and armature tooth.When rotor permanent magnet and stator tooth meet or separate, near it, magnetic field changes, and the magnetic energy of air between permanent magnet and stator tooth is changed, and the change of magnetic coenergy produces torque; Meanwhile, cogging torque also can think the reluctance torque that teeth groove produces relative to the magnetic resistance change rate of permanent magnet current source.Cogging torque can run motor and cause many-sided negative effect: such as torque ripple, vibration & noise.
Stator body top between teeth groove and teeth groove arranges auxiliary flute, be equivalent to increase cogging torque primitive period number, setoff effect is play to the cogging torque of original teeth groove, thus total cogging torque amplitude is reduced, effective air gap is also made to increase, also be conducive to reducing cogging torque, part motor can be eliminated and run noise, reduce body vibration.
Further, the quantity of the described auxiliary flute that each described teeth groove is corresponding is 3.
3 auxiliary flutes enhance reduction cogging torque, can eliminate part motor and run noise, reduce the effect of body vibration.
The beneficial effects of the utility model: some magnetic flux holes are set at stator body, its role is to the trend changing stator radial magnetic circuit, radial flux is passed through from magnetic flux hole, the narrow and small loop that eddy current is limited in magnetic flux hole is flow through, electromotive force in these loops is less, can reduce eddy current loss significantly, and stator caloric value is reduced, thus raise the efficiency, reduce energy consumption.
