Main technical features of an iron core structure of motor rotor provided by the invention are that on a rotor iron core of a rotating motor, along a circumferential direction of a rotation axis of the motor as a center of circle, a plurality of through-hole-shaped spaces spaced apart from each other are arranged on the iron core in sequence. When the through-hole-shaped spaces form obstacles to a magnetic circuit in the rotor, the through-hole-shaped spaces are also provided for insertion of a plurality of straight rod-shaped coupling elements made of non-permeability magnetic material to fix an overlapping state of a plurality of silicon steel plates of the iron core in order to improve an overall rigidity of the iron core and reduce a possibility of deformation or damage of the silicon steel plates caused by centrifugal force of high-speed rotation.
