Determine slot 113；In addition, being additionally provided with flow-conveying groove 112 between wire casing 111 and fixing groove 113.Therefore when motor operates, injected
Cooling medium can sequentially pass through the flow-conveying groove 112 on each stator punching, finally by the other end of stator core flow out；
During this, cooling medium can be contacted more fully with the internal structure of stator core；In turn, stator teeth and yoke portion,
And all decreases to some degree of the temperature at the air gap of motor, meanwhile, the temperature on rotor also can decrease；To,
The Wen Sheng that motor can preferably be reduced, improves the performance of motor.
Preferably, multiple inner diameter channels 11 are arranged to identical shapes and sizes, and by multiple inner diameter channels 11 along punching sheet
The inward flange of body 1 is uniformly distributed；Meanwhile multiple outer diameter grooves 12 are also configured as identical shapes and sizes, and by multiple outer diameters
Slot 12 is uniformly distributed along the outer edge of punching ontology 1.In this way, allowing for cooling medium can uniformly flow into often in circumferencial direction
In a inner diameter channel 11 and each outer diameter groove 12, in turn, each position of stator core can more tend to equal Wen Sheng, effect
More preferably.
On this basis, the number of the outer diameter groove 12 on punching ontology is set as more than the number than inner diameter channel 11 one,
So that when inner diameter channel 11 can be formed along the groove of the central shaft extension of stator core, outer diameter groove 12 can be formed with stator iron
Axial screw slot, does structure qualification centered on the central shaft of the heart；In turn, increase the cooling medium and stator iron for flowing through outer diameter groove 12
The contact area of the heart.
When specific processing, several adjacent pressings of punching ontology 1 are fixed as one group of punching group, and all punching sheets
Outer diameter groove 12 on body 1 corresponds, and the inner diameter channel 11 on all punching ontologies also corresponds；In every group of punching group
Outer diameter groove 12 on punching ontology 1 is overlapped with corresponding two outer diameter grooves 12 respectively, and the punching ontology 1 in same group is fixed to each other
Punching group is fixed to each other together and then successively；Outer diameter groove before two groups of punching groups are fixed to each other on punching ontology 1
12 be all to overlap, and on this basis, first by one of punching group, axis is rushed with respect to another centered on the central shaft of stator
Piece group rotates a certain angle, so that the corresponding inner diameter channel 11 in two groups of punching groups is completely superposed, and makes two groups of punchings
The outer diameter groove 12 of piece group is slightly staggered, and is then fixed again；At this point, interior on all punching ontologies 1 of composition stator core
Diameter slot 11 still can form the groove that a length direction along stator central axis extends, and outer diameter groove 12 can then be formed with stator
Axial screw formula groove centered on central shaft, moreover it is possible to increase the contact surface of the cooling medium and stator core that flow through outer diameter groove 12
Product preferably reduces the Wen Sheng of motor.
Preferably, inner diameter channel 11 is set as 36, and outer diameter groove 12 is set as 37；In this way, two adjacent groups punching
Group only needs 10 degree of relative rotation, convenient for measuring.
Preferably, the thickness of punching ontology 1 is set smaller than 0.35 millimeter, uses thickness for 0.5 relative to traditional
For the punching ontology 1 of millimeter；The punching ontology 1 that the present embodiment two provides, eddy-current loss smaller, i.e. iron loss smaller have reduction
The effect of motor temperature.
Further, the iron loss that feasibility when comprehensive process and stator generate, the thickness of punching ontology 1 can be arranged
It is 0.2 millimeter.
Preferably, punching ontology 1 is manufactured using silicon steel sheet, silicon steel sheet ingredient is that the extremely low silicon-iron soft magnetic of phosphorus content closes
Iron can be improved in silicon resistivity and maximum permeability is added in gold, reduces coercivity, core loss (iron loss) and magnetic aging；In turn,
Reduce the Wen Sheng of motor.
Embodiment three
Correspondingly, the present embodiment three provides a kind of stator core comprising determine involved in multiple above-described embodiments two
Sub- punching (concrete structure of the stator punching no longer repeats one by one)；The size and shape all same of multiple punching ontologies 1,
And multiple punching ontologies 1 stack gradually and are fixed as entirety；Multiple outer diameter grooves 12 on multiple punching ontologies 1 are one by one
It is corresponding, and each outer diameter groove 12 with the connection of the corresponding outer diameter groove 12 (see also Fig. 1 in above-described embodiment one and
Fig. 2).
Obviously, the stator core that the present embodiment three provides is more on multiple punching ontologies 1 because including said stator punching
A outer diameter groove 12 corresponds respectively, and multiple outer diameter grooves 12 on each punching ontology 1 on other punching ontologies 1 with its
Corresponding outer diameter groove 12 is connected to so that cooling medium can pass through each outer diameter groove 12 on every punching ontology 1；Into
And so that stator core can play all advantages of said stator punching, can preferably reduce the Wen Sheng of motor.
