Abstract

The invention relates to a structure of a motor stator core and a cooling method for a motor stator based on the structure of the motor stator core. The structure is characterized in that the stator core is formed by splicing and combining stator yoke units and stator tooth units, wherein the quantities of the stator yoke units and the stator tooth units are the same, and are equal to the slot number Z1 of a stator; the stator yoke units and the stator tooth units are formed by laminating oriented silicon steel sheets; a stator yoke unit is connected between every two adjacent tooth units; the tooth units and the stator yoke units are in joggle joint; the silicon steel sheets of the stator yoke units are oriented circumferentially; and the silicon steel sheets of the stator tooth units are oriented radially. The cooling method is selected from one of air cooling, water cooling and oil cooling. The structure has the advantage that the motor has the characteristics of low ferromagnetic loss, high efficiency, low torque pulsation, low slot effect, low running noise, low wind resistance, high slot fullness rate of a stator winding, high utilization ratio of a silicon steel sheet material, suitability of the stator for automatic mass production and the like.
