[0003] According to CN201721105383.4, this utility model discloses a rotor core and a rotor. The rotor core has a first magnetic slot and a second magnetic slot. Both the first and second magnetic slots include multiple slots arranged at intervals along the circumference of the rotor core.

When the rotor core is manufactured, the weight of the iron is generally heavy. The heavy rotor core affects the inertial load when the motor starts, thus affecting the dynamic response speed of the motor. Summary of the Invention

This solves the problem that existing rotor cores are generally integral structures composed of iron components, with the connecting areas of the rotor core made up of a large number of iron components. When the rotor core is manufactured, the weight of the iron components is generally heavy, which affects the inertial load during motor startup and thus affects the dynamic response speed of the motor.
