[0003] During the use of the above device, when the stator core is installed on the motor, due to its simple structure, a large amount of kinetic energy is required to drive the stator core to rotate when the motor drives the stator core to rotate; therefore, we propose a stator core structure for the motor to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a stator core structure for a motor, so as to solve the problem that when the existing stator core is installed on the motor and works, due to its relatively simple structure, a large amount of kinetic energy is required to drive the stator core to rotate when the motor drives the stator core to rotate.
