The segmented iron core IPM plastic package forming rotor comprises a rotor iron core, magnetic shoes, a PBT and a shaft, wherein the rotor iron core consists of a plurality of same iron core segments in an encircling manner; a magnetic shoe groove and an anti-leakage flux groove for reducing leakage flux are arranged between every two adjacent iron core segments respectively; every two adjacent iron core segments are separated from each other through the corresponding anti-leakage flux groove and the corresponding magnetic shoe groove; each iron core segment is provided with a positioning structure for realizing the positioning of the corresponding iron core segment respectively; each magnetic shoe is inserted intothe corresponding magnetic shoe groove; the magnetic shoes are fixed on the rotor iron core through the PBT; and the shaft is connected with the magnetic shoes and the rotor iron core into a whole body through the PBT. Through the technical scheme, the rotor iron core is segmented into the same iron core segments, so that the magnetism isolating bridge leakage flux problem of a traditional integral rotor iron core is solved, the utilization rate of the rotor magnetic shoes is improved, and the power density of the motor is improved.
