The utility model relates to a type rotor core, electric motor rotor and motor are buried underground to permanent magnetism, this permanent magnetism bury type rotor core underground and include therotor utmost point, the mid point of the neighboring of the rotor utmost point, be rotor axis extremely with rotor core's rotation center's line, the neighboring of the rotor utmost point includes a plurality of end to end's in proper order segmental arc, and one of them segmental arc is arc, for first segmental arc, does first segmental arc become an axle symmetry shape for the axis, and the angle of the central angle of first segmental arc correspondence is 12 16. The neighboring of the rotor utmost point sets up a plurality of end to end's in proper order segmental arc, is favorable to reducing to have the average air gap that type rotor core's motor was buried underground to permanent magnetism, improves the motor output moment of torsion. And, the angle of position through optimizingfirst segmental arc and th
