When the coiling stator, the enamelled wire of winding is that the coiling that is wrapped in stator core after the tension is extremely gone up.The shortcoming of prior art is, enamelled wire is when the bending of stupefied 13 places of the square of process yoke sheet, stator core can produce bigger reaction force to winding, these reaction forces will damage the insulating barrier of enamelled wire, reduce the unfailing performance of winding, cause the fraction defective of stator to raise, and then influence product quality.
The utility model content
The technical problems to be solved in the utility model is, a kind of stator core of motor is provided, and reduces the damage of stator core to the insulating barrier of winding enamelled wire, thereby reduces the fraction defective of stator, improves the quality of products.
For solving the problems of the technologies described above, the utility model provides a kind of stator core of motor, by two yoke sheets be clipped in stacked between two described yoke sheets and constitute for a plurality of laminations of one, the periphery of described stator core is protruding with a plurality of coiling utmost points, it is characterized in that the stupefied of described yoke sheet that is positioned at described coiling utmost point place is fillet.
As preferably, the coiling of described stator core extremely is provided with winding, and described stator core is coated with insulating barrier with the position that described winding contacts.
As preferably, the coiling of described stator core extremely is provided with winding, and there is an insulating barrier at the position that described stator core contacts with described winding by surface heat is molded.
The utility model also provides a kind of stator of motor, comprises aforesaid any one stator core.
The utility model provides a kind of rotor core of motor, by two yoke sheets be clipped in stacked between two described yoke sheets and constitute for a plurality of laminations of one, the periphery of described rotor core is protruding with a plurality of coiling utmost points, it is characterized in that the stupefied of described yoke sheet that is positioned at described coiling utmost point place is fillet.
The utility model also provides a kind of rotor of motor, it is characterized in that, comprises aforesaid rotor core.
Compared with prior art, the stator core of motor of the present utility model and rotor core can reduce the damage of iron core to the magnet wire insulation layer of winding, have improved the quality of stator and rotor, have reduced the product fraction defective.
