Abstract
The invention relates to the technical field of a motor, and especially rates to a rotor stacked type iron core for the motor. The rotor stacked type iron core for the motor comprises an iron core body, iron core single pieces A and iron core single pieces B. According to the rotor stacked type iron core for the motor provided by the invention, the adjacent iron single pieces are different in shapes; the iron core single pieces are adhered together mutually; therefore, the weight of the iron core itself is reduced; the efficiency of the whole motor is improved; the magnet fixing lug bosses and the magnet positioning lug bosses in the rotor stacked type iron core can position magnets rapidly and accurately; moreover, the rotor stacked type iron core is rational in structure design and stable and reliable in use and is applicable to popularized use.
