The utility model discloses a rotor core convenient to manufacture, comprising a plurality of iron core sheets stacked together. The iron core sheets are provided with a plurality of rivet holes and heat emission holes used for cut-through. The iron core sheets are uniformly distributed to overlap to form three iron core groups connected together. Each iron core group is formed by a plurality of same iron core sheets. Each iron core sheet is provided with two groups of rivet holes distributed uniformly. Each iron core sheet is provided with two key grooves. The iron core sheet is provided with a balance hole on the periphery of the heat emission hole. The rotor core shortens manufacturing labor-hours and simplifies manufacturing steps, and reduces manufacturing cost in an integrated manner. The rotor core is advantaged by reducing manufacturing labor-hours, simplifying manufacturing steps, and reducing manufacturing cost in an integrated manner, providing convenience for rivets to pass through, and the motor is stable in operation, torque and motor noise are low, workload of dynamic balance correction is simplified, and manufacturing cost of the motor is reduced.
