Description

Technical Field

[0001] The utility model relates to the technical field of rotor cores, in particular to a stator and rotor core of an automotive motor. Background Technique

[0002] The rotational torque of the rotor of an automotive motor comes from the induced magnetic field acting force between the stator and the rotor of the motor. The functions of the rotor core and the stator core are the same, both to enhance the intensity of the induced magnetic field and the density of magnetic force lines, thereby enhancing the magnetic field acting torque between each other.

[0003] During the transportation of the existing rotor core, when it is damaged by being knocked, since it is not convenient to disassemble and transport it, it is not convenient to disassemble and replace the individual components on it, thus causing waste of resources.
